Engineered and manufactured in the U.S.A. The Whisper Series Compressors
reduce stationary compressor DBA ratings by as much as 25%! A noise
suppression device was first conceived by Polar Air engineers after
feedback from competitor compressor users revealed a large number of
complaints regarding the extreme noise level of their compressors in a
work environment. Stationary air compressor noise levels typically
require owners to incur the added expense of a building or structure to
house the compressor in an attempt to reduce noise in the work
environment. The Whisper can be installed and operated in all
Garage, Farm Shop, and Industrial applications which eliminate the need
for traditionally expensive and often inadequate separate buildings or
structures to house the air compressor. The Whisper silent air systems
are already installed on the back of the tank with brackets that are
fabricated for easy removal and low profile.
dissipates compressor intake noise by channeling the intake air through a
series of baffle plates and pre-filter media within the silencer
cabinet. As a result, the piston intake noise is trapped and dissipated
within the silencer structure. As a result, the piston intake noise is
trapped and dissipated within the silencer structure. It also acts as a
secondary filtration for cleaner air.
Industrial Series offers all the same quality and durability as our
Plus series without all the extra cost of added features. We offer this
series so that anyone can afford to have an Polar Compressor.
This Industrial 10 HP 2 Stage Inline 1 Phase Vertical 80 Gallon Piston Air Compressor is designed for up to 50,000 hours industrial use with proper maintenance. This unit features our low RPM pumps and delivers 38 CFM @ 100 PSI. Our unit features automatic or continuous run functionality and is SUPER COOL & SUPER QUIET!
At the core of our Polar compressors is our Eaton Compressor pump. These pumps are SUPER quiet in operation and built too last! We start with a solid cast iron crankcase.
Unlike some competitor’s aluminum body crankcases – our solid cast iron
crankcase will ensure stable crankshaft alignment and will handle more
work load under heavy load conditions.
Our pump also features a precision balanced solid cast iron crankshaft
with Timken-Style stainless steel roller bearings on the front and rear
of the crankshaft to ensure smooth & efficient operation with less
drag and less energy use.
Our pumps also feature several other key components that ensure durability and performance!
steel connecting rods with replaceable rod bearing inserts. This allows
our rods to be rebuilt! 99% of our competitors now use “throw-away”
aluminum connecting rods in their pumps that have no re-build
- Removable 100% cast iron cylinders. These solid cast
iron cylinders are more stable under heavy workloads and do not warp
from heat. Most of our competitors are using aluminum cylinders with a
pressed-in sleeve that warp under extreme heat. This makes competitor
pumps good for about a 40-50% duty cycle – while claiming a 100% duty
cycle. Most of the pumps with aluminum cylinders have to be replaced in
1-2 years because they would not hold up under heavy use. Not our Air
pumps! Our solid cast iron cylinders can “take the heat” and are
designed to perform on heavy load demands.
- All cast iron cylinder heads. Cast iron heads are more durable and dependable for trouble free operation.
valve design” intake and exhaust valves. Disc valves have been around
for over 100 years and have been proven to perform. Most of our
competitors are using “throw-away” reed valves which are not nearly as
durable and can’t be re-built. Our disc valves come right out of the top
of the cylinder head where they can be serviced in minutes instead of
hours like reed valves.
- Top quality compression and oil rings. Our rings ensure performance with low oil carry over (1-5 PPM).
- Precision ground pistons machined to tight tolerances ensures low oil carry over.
- Premium “non-absorbent” gaskets prevent oil seepage from pump.
cast iron flywheel with built-in fan. The extra weight of our cast
iron flywheel during run cycle gives the pump more “throw” on the
compression stroke which will result in fewer loads on the electric
motor. Some manufacturers use aluminum flywheels that do not have the
proper weight ratio to give the proper throw on the compression stroke
when the pump is running.
- Built-in head unloaders. These
unloaders are built into the intake valve assembly on the compressor
head and perform a valuable function. They unload or open the intake
valves under constant run applications. This feature reduces internal
pump heat from compression because the intake valve is held open
throughout the unloading cycle. This allows fresh air to come into the
cylinder chamber. Under the compression stroke, the unloader holds the
intake valve open allowing the air to blow back out the intake
filter. This fresh air absorbs the heat out of the pump under heavy
- Built-in inter-cooler and after-coolers. The
inter-cooler allows air to be cooled between stages while the air cooled
after-cooler provides a second cooling stage that cools the air before
it goes into the tank. Our after-cooler also includes an all copper
main feed line from the pump into the tank.
Bottom line …
only do we have one of the highest quality, most durable compressor
pumps in the industry … but we have one of the lowest RPM compressor
pumps on the market. That’s the Eaton difference!
RPM is a very critical factor in both performance and longevity. For
that reason, on most of our compressors, we normally “GO BIG”
over-sizing our pumps and running them at lower RPMs than most
manufacturers. Our bigger, low RPM pump can still yield a high CFM
output because both our bore and stroke are bigger. Not only do you get
the big CFM output, but the lower RPM operation also reduces friction
and heat buildup to extend pump life!
NAME BRAND ELECTRIC MOTOR
These units have name brand OPD (open drip motors) on them. They carry a 5 Year warranty.
It is most important to note that all of our motors are low RPM motors (1750 rpm)
… most manufacturers now use higher RPM motors (3450 rpm). 1750 RPM
motors run much cooler than 3450 RPM motors because of the higher torque
factor. They also yield low harmonic distortion, provide much higher
torque in cold weather starting and require less electricity under start
Additional Motor Features:
- Large 1-3/8” output shaft
- High quality ball bearings on the front and rear of the motor shaft
- Large starting and running capacitors
- 15 Service Factor load. This means the motor can be pulled 15% over full load for more break horsepower
- Dynamically balanced armature for low vibration levels
- BELT GUARD We
at Eaton Compressor are always concerned about durability and about your
safety in everything we build. Our belt guards are no exception. Built
right here in the USA with 13 G steel and premium grade expanded metal,
we manufacture our belt guards to be tougher than any you will find in
the industry today. For your safety, our belt guards are OSHA approved.
- AIR TANK We
at Eaton are always concerned about durability and about your safety
in everything we build. Along with this philosophy, our air tanks are
manufactured right here in the USA and are ASME code compliant in 50 states including California.
- CONTROLS & COMPONENTS We at Eaton Compressor use only top quality components on our compressors.
- Top quality pressure switches with an adjustable screw which allows you to adjust your pressure higher or lower.
brass check valves with Teflon Seating. All check valves on our
compressors are all brass with a Teflon seating. This reduces tank noise
when the compressor is running because the Teflon seating is much
quieter than other materials and insulates noise when valves are opening
and closing during the compression stage.
- 100% brass ASME
safety valves. For your safety all safety valves are 100% brass and
comply to ASME code. Valves are preset and sealed for correct settings.
In the event that your compressor would not turn off, our safety valves
open keeping compressor from building too high of a pressure level in
the tank. This will help to avoid the potential of tank rupture.
- Top quality plumbing fittings are used to maintain proper sealing when connected to the tank.
- High quality 100% brass ball valves are used for turning air on and off from the air receiver.
tank water drain pipe plumbed out the front of the unit with a ¼” ball
valve handle for easy tank draining. Eliminates the hassle of draining
the tank with the typical petcock style drain under the tank.
starting. Thanks to built-in head un-loaders built into the intake
valve assembly on the compressor head, “load-less” staring is built into
this unit. This unloads the pump so the pump will not start under
direct head pressure. Without this feature, this will cause motor damage
under starting cycle.
- MOTOR PULLEY AND BELTS We
use taper lock style 2-groove pulleys (not single groove). We also use
dual 2-groove, B-Style belts to drive our pumps. This combination is
best for a couple of reasons.First, dual belts ensure long belt life and
yield low vibration which makes for smoother, more quiet operation
because the dual belts do not have to be as tight as with a single belt
setup. The tighter the belts (as with a single belt setup) the more
load on the compressor pump and motor bearings which decreases the life
of both.Second, our taper lock pulleys are much better than a fixed bore
pulley with a set screw. A taper lock design will lock the pulley in
position to the motor shaft allowing it not to loosen or move on the
motor shaft.Our 5-year warranty should not only give you, our customer,
complete confidence in our product – but also in our commitment to
excellence in quality, support and service.
