"Hand Held" Large Surface, Deep Cleaning/Polishing/Buffing/Surface
(Manufactured since 1996)
"DRUM TYPE" Polishers
have been developed to RAPIDLY "deep clean" &
polish, plus, provide a "consistent" finish,
on very large surfaces.
The SPEC Machines "Drum"
type polishers are indeed, the most advanced, reliable, versatile
and largest, industrial "hand held" surface polishing
machines, available on the market today.
type polishing machines do not completely replace, "circular"
type polishers, but greatly augment the polishing / cleaning process,
specifically on large surfaces. "Drum" type polishers,
used with proper techniques & polishing products, will allow
for a far more efficient, consistent and longer lasting finish,
on a wide variety of surfaces, (painted, bare metal, aluminium,
composite, plastic, acrylic, Plexiglas, Lexan, etc.,).
The most notable benefits of utilizing air driven "DRUM"
type polishers is a greatly reduced labour time, (approximately
1/3rd to 1/2 that of circular polishers. ie: a DeHavilland
Dash 8, - 78 - 100 man hours with circular polishers verses 22
- 30 man hours with Drum type polishers. An AIRBUS A320, 6-800
hrs vs 2 -300 hrs using DRUM type polishers. A Bombardier "Global
Express" wing leading edge 2 - 4 hrs, verses 8 - 12hrs.), with
improved safety, to not only the operators, but to the work surface
The SPEC Machines Industrial "Drum"
type units are indeed, the most advanced, reliable, versatile
and largest, industrial "hand held" surface
polishing machines, available on the market today. (The next
step up would be Robotic or Semi Robotic equipment.)
Keeping todays commercial aircraft "clean"
is an important and ever increasing challenge. Commercial airliners
are getting bigger, are being pushed through more "cycles",
and are operating in increasingly harsh environments. The
products we represent, the equipment we manufacture and techniques
we recommend, address these challenges safely and efficiently.
As with any "restoration" or initial cleaning you
may find you will use more product in the beginning, but after
the initial "polishing/deep cleaning" of each aircraft,
a "substantial" decrease in quantity and type of
product will be required for routine maintenance. For instance,
a 1 gallon (3.78Liter) ROLITE Polish Sealant will do 1 or 2, "737"
size aircraft quite easily, (1, if including wings, tops
and bottoms or 2, if doing fuselage only). Initially, the use
of the products like the ROLITE "SUPRA 90"
polishing compound is highly recommended, (the Rolite
"Pre Polish"(GP266) may be necessary for some areas),
to deep clean and polish painted surfaces smooth, (without affecting
the paint hardness). This step will "deep clean" and
prepare the paint efficiently and properly for the use of the
ROLITE Polish /Sealant, or similar type product. Once the
exterior of the aircraft has been "polished properly",
regular "Polishing", is really, totally unnecessary,
even in a tropic / salt water environment. To maintain the exterior
finish, only an annual, or in extreme cases, a bi-annual "polishing"
is usually all that is required. Some areas of high wear
or abrasion, like aft of: exhaust, landing gear on belly, APU
protection plate, leading edge areas and such, may require more frequent
attention. A good annual or bi-annual "Polishing" will
most definitely retard, if not completely prohibit, any type of
surface corrosion. Regular "Cleaning" or "Washing",
with an appropriate product, every two months or so, is usually
all that is required to keep all areas clean to allow easy identification
of any visible defects, cosmetic or otherwise. General cleaning
should be done with a good surface cleaner on an "as required"
basis, dependent on your operational environment. The "bright
work" is easily maintained by a regular simple "wipe
down" with the ROLITE Polish / Sealant to clean, maintain
and "re brighten" the surface.
There are two basic large models. The SPEC
"SA"(short arm) and "LA" (long arm). Simply
put, the "SA" is simply more versatile especially for
"up close" work. The "SA" can be turned
into an "LA" (long arm) by simply attaching a 2 ft extension
handle. The SPEC"LA" cannot be turned into an "SA".
The SPEC "LA" is primarily for doing large surfaces
from a "stand off" distance. Both units use
the exact same Atlas Copco power unit. All parts from
all units are interchangeable.
The SPEC Model "SD"
uses a special drum that can
accept standard "Synthetic" abrasive 8"D X 3"ID
wheels, ("stacked") or "Combo Flapwheels".
It has been designed for surface "texturing" or rapid
oxidation/material removal that can be executed, quickly, efficiently
and safely. (On "large" surfaces, approximately
5 times quicker that Palm or "Jitterbug" hand type sanders.)
Contact us for more details.
Please note: "DRUM TYPE" polishers are intended for, and
work best for, finishing and general "routine"
maintenance on large surfaces. They do not work well for
corrosion or material removal, unless used with the
SPEC "SD" drum & speciality abrasive brushes, (available
from the several manufacturers). For this type of work or "initial"
restoration on aluminum and bare metals, the "SD"
Drum is far more productive and will rapidly remove corrosion.
( On smaller pieces or areas, the SPEC 1300B Series
II "Detailer" with standard 6" polishing wheels
is excellent for this purpose. Circular polishers, are also effective,
but they will leave polishing, (swirl), marks. The DRUM TYPE polishers
with the Wool or Cotton pads on a regular 4 or 5 inch standard
drum will rapidly remove the "polishing marks" left
by the circular type polishers and allow for rapid and efficient
The SPEC Machine model "SA",
"LA", "SD" and SPEC 1300B "Detailer"
Drum polishers all require a consistent air supply of a minimum
of 30 cfm (cubic feet per minute) @ 85 - 90 psi, for maximum performance,
(full torque). A "Rotary Screw" or "Helical"
type compressor is recommended. An "AIR DRYER" or "CHILLER"
is aslo highly recommended for optimum tool performance and longevity.
Our ongoing commitment
is in providing our customers with the finest products possible.
SPEC Distribution International Inc. has undertaken the task of
designing, developing & manufacturing the most advanced, reliable
& versatile, industrial, "hand held", large surface
polishing machines, available on the market today. They may look
simple, but have been designed for INDUSTRIAL use. We have taken
all the best features of current and past "DRUM" type
polishers designs and improved on them. We have designed and built
this equipment with extensive and valuable input from our customers
who specilize in the "large surface" industrial polishing
markets. These clients include: BOMBARDIER AEROSPACE Inc, LEARJET
(Div. Bombardier Aerospace), NASA's (Dryden Flight Resaerch Center),
AVIONET Inc., AERO MEXICO, LUFTHANSA TECHNIK, EXECUJET (Dubai),
QATAR Exec FBO SKYSERVICE, INNOTEC / EXECAIRE, FALCON AVIATION
Dubai, JA AIR CENTER Chicago, AIR CANADA & AIR CANADA "JAZZ"
to name just a few.
Features and Benefits of the
SPEC Machines Industrial DRUM Polishers are:
- Productivity: On large surfaces the SPEC Machines
"DRUM" type polishers are unparalled in their capability
to reduce labour time and increase producitivity."DRUM"
type polishers do not completely replace, "circular"
type polishers, but greatly augment the polishing / cleaning
process, specifically on large surfaces. "Drum"
type polishers, used with proper techniques & polishing products,
will produce a far more efficient, consistent and longer lasting
finish, on a wide variety of surfaces, (painted, bare metal,
aluminium, composite, plastic, acrylic, Plexiglas, Lexan,
etc.,). The most notable benefits of utilizing air driven
"DRUM" type polishers is greatly reduced labour times,
(approximately 1/3rd to 1/2 that of circular polishers. ie: a
DeHavilland Dash 8, - 78 - 100 man hours with circular polishers
verses 22 - 30 man hours with Drum type polishers. A Bombardier
"Global Express" wing leading edge 2 - 4 hrs, verses
8 - 12hrs. An AIRBUS A320, 600-800 hrs down to 250 hrs.),
with vastly improved safety, to not only the operators, but to
the work surface itself.
- QUIET: Most of the current air driven drum polishers
that operate in the over 1 hp range, produce motor noise levels,
at or above, 95 decibels (a Boeing 747 is about 145 decibels
on take off). SPEC Machines, have been designed
& tested to operate, at full throttle ("free"),
below 75 decibels at a distance of 1.5 meters, (4ft).
This is a huge plus, in not only reducing overall fatigue for
the operator, but for those working on other tasks, in the same
- For comparison : Common
noise levels in decibels (db), (Increasing
Normal conversation -50-60 db
- A SPEC "LA" ,"SA"
& "SD" DRUM Polisher @ full throttle < 75 db
A loud radio -65-75 db
A busy street -78-85 db
A heavy truck about 7 metres (23 ft) away -95-100 db
A pighouse at feeding time -110 db
A chain saw -115-120 db
A jet aircraft taking off 25 metres (82 ft) away ->140 db
- VERSATILE: Interchangeble configurations. SPEC
Machines are easily changed in configuration, simply
using a standard 3/16" Allen type key. The air motor or
"heart" of the machine can be attached to any one of
the three drum sizes/type with one, 10/32 Grade 8, SS
bolt. The drum/motor assembly can be attatched to either of the
two types of handles. The control handle is adjustable
to assure full, safe and accurate operator control of the tool,
regardless of the type of operation, all with a 3/16" Allen
- SIMPLE: SPEC Machines utilize "standard"
parts. For instance, replacement air motor blades for the Atlas
Copco air motor are available WORLD WIDE, through any Atlas
Copco dealer or representitive. All the bearings we use
are "standard "and available from any reputable bearing
- POWERFUL: SPEC Machines use, an Atlas Copco
"LZB" industrial air motor with "sealed &
isolated" TRIPLE gear reduction units, that operate at 2550
RPM Max., producing 5.5 ft/lbs of torque, @ 2500 rpm(at the "DRUM"),
with an air consumption of 30 cfm @ 90 psi.
- INDUSTRIAL DEPENDABILITY: SPEC Machines use
Torington® or RHP Brand, Heavy Duty, industrial "roller
type" bearings in the "drum to motor" contact
surface, riding on a special hardened, "tool steel"
race. Aside from an occasional light grease application, these
bearings are maintainence free and extremely durable. They are
completely isolated from any air flow, entering or exhausting
the air motor, eliminating any contamination. Our "Drums"
are machined from a single piece of Delrin High
Density Composite Synthetic, (4" and 5"Diameter X7"Wide)
& are capable of absorbing an incredible amount of force
from a direct impact, ie: accidental dropping of the unit or
hitting an edge or corner, of a steel work table. This allows
the drum to remain round and true, for vibration free performance.
(Aluminium drums can easily come out of balance, producing vibrations
at high speed that is damaging to the equipment, produces fatigue
and difficulty for the operator plus, produces an "uneven
finish" on the surface.)
Operator safety is of prime concern. The manner in which
"DRUM" type polishers are used, allow the operator
to work in a natural standing position, controlling only the
rate at which the machine moves away from the operator, across
the surface. Circular polishers, on large surfaces, require unnatural
operator twisting, resulting in, rapid operator fatigue, potential
back problems and inadequate tool control.
The SPEC Machines "Drum" type polishers
are indeed, the most advanced, reliable, versatile, productive
and largest, industrial "hand held" surface polishing
machines, available on the market today. Important
to note: Similar units, available on the market, operate in the
over 3000 RPM range and at lower torque outputs. The lower rpm
(2500 rpm)with higher torque output SPEC Machines
units, allow for far less stress on the polishing pads and parts,
and allow more forgiving and exacting operator control.
- SAFE: Operator saftey is of prime concern. The manner
in which "DRUM" type polishers operate, allow the operator
to work in a "natural "standing position, controlling
only the rate at which the machine moves away from the
operator, across the surface. Circular polishing on large surfaces,
require unnatural operator "twisting", resulting in
potential back strain and loss of tool control.

1 year warranty on all parts, (except air muffler
& air motor blades.) Any warranty repair or replacement
of parts shall be done at NO CHARGE within the warranty period.

configurations. Above, the SPEC Model "SA" in
it's standard configuration for "BUFFING" and "FINISHING"
with a 4"X8" Cotton Finishing pad on the DHW 4"
X 7" (#SPEC47) Composite drum. The Model "SA"
can be converted to either of the configurations below, shown
with the specially designed drum (#SPEC37) that will accept
either a 4"(shown below on left) or 6" wide X 8"
diameter, 3M Scotchbrite® drum, for "SATIN"
finishes, or as in the right side, using the same drum, it can
accept single or multiple, (stacked) standard 1/2"wide X

varieties) for tool mark repair, heavy material suface alteration
or "texturing" etc. Contact us for more information

a standard 3/16" allen key, (comes with each unit) to assure
proper and safe operator control, "over center" for

Above shows some of the different
configurations of the SPEC "SD" using the

the middle is the 8" wide (20.3cm) wide"COMBO Flap Wheel"
(Grey Scotchbrite interlaced with 280G Aluminum oxide paper)
perfect for heavy corrosion or paint removal or metal surface
"texturing" producing a "SATIN" Finish. The
"SD39" Drum can
be used with on both the SPEC "SA" and "LA"
models. To change between the Standard 4" or 5" Buffing
drums and the SPEC37 drum involves only undoing
a 10mm SS bolt and switching drums, (Less than 1 minute)
NOTE: Standard Model "SA" & "LA"can
easily be converted to this configuration by simply purchasing
the SPEC "SD39" DRUM separately.
Shown below is the SPEC
Machines Model "LA" with the 5"
X 7" drum and SPEC57 pads. This configuration is for
polishing very large surfaces from a "stand off" distance
or standing position. For instance, aircraft fuselage sides and
crowns or in the case of the top wing surfaces, the operator can
be in a comfortable standing position, as opposed to "hunched
over" when using circular type polishers. The use of an optional
2 ft extension allows for a greater (and safer) "reach"
(see pics below). The tool actually becomes "weightless"
on fuselage sides and crowns as it will "climb" or "walk"
away from the operator. All the operator has to do, is
control the speed or rate, of the walk or climb. The control handle
(shown in the extended position below) can be easily re-positioned
for maximim operator comfort and control.

Parker Hannifin "EZ-Mate" quick connect-disconnect
SAFETY throttle, (Speed Control).
Each SPEC Machines unit comes with a
Parker Hannifin "EZ-Mate" quick connect-disconnect
SAFETY throttle. This unique design allows the throttle
to be part of the air line, independent of the tool. Similar systems
require a throttle with each tool. In a scenario where you have
three types of tools but only one air line, you simply plug the
tool directly to the line and you have instant throttle control.
As an added saftey feature, the tool can only be connected
(or disconnected) with the throttle in the CLOSED position.
This prevents accidental connections to a 2 hp, open
throttled machine, spinning at 2000 +RPM. (The results can
be quite exciting.Trust me, I know!) The "EZ-Mate"
has venting ports, that "exhaust" down stream air to
atmosphere, so disconnect is at ZERO pressure, thereby eliminating
dangerous "HOSE WHIP". The "EZ-Mate"
is not only safe but allows the operator "precision"
speed control of the tool.

Capabilities" of the SPEC Machines "DRUM"

The picture on the top left is of the horizontal tail
on a DeHavilland "DASH 8". It is approximately 30 ft
(15 meters) high and you can only get the lift so close to your
work. The center picture demonstrates the "reach" of
a SPEC Machine in a rather tight area for a scissor truck
or similar. The picture on the far right shows a polishing operation
on a wide body AIRBUS A330-300 using one of the drum buffers with
two, 2 ft (61 cm) extension handles attatched. (A 6 ft (1.8m)
extension is also available). This truly demonstrates the safe
"reach capability" of the SPEC Machines polishers.
Try maneuvering a lift between the fuselage and engine nacelle
without sweating about hitting the aircraft. Accomplishing these
jobs, with anything less than a SPEC "DRUM" type
polisher, with a 2 ft (61 cm) extension handle(s) installed, is
not only almost impossible, but downright dangerous. The less
you have to maneuver a lift, around & next to, the aircraft,
the less chance for "an accident". The job becomes quicker
& more importantly, far safer, for all concerned.
