Silent Air Piston Compressor! 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 Eaton 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.The Whisper 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.
COMPRESSOR PUMP At the core of our Eaton compressors is our 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!
RAISED MOUNTING PLATFORM Our raised pump platform design is a nice feature for keeping your oil cool within the pump. This platform raises the pump approximately 2” off the mounting base plate. This allows for 100% constant flow of cool air from the flywheel fan to circulate by not only the top & sides of the pump crankcase, but also opens the underside of the crankcase to cooling air flow. This ensures cooler oil temperatures within your pump. Cooler oil not only helps to lubricate the pump but also pulls the heat off the pistons and connecting rods - reducing wear and adding many years of life to the compressor pump.
NAME BRAND ELECTRIC MOTOR A tough pump needs a tough motor that can drive it! Eaton uses only high quality name brand premium efficiency motors that meet all UL and CSA requirements.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 up.These motors are TEFC (totally enclosed – fan cooled) style motors which keeps harmful dust and particulate out of the interior of the motor. This allows them to be used in dusty commercial and industrial environments without worrying about maintenance.The running and starting windings on these motors are all 100% copper wound for premium efficiency, reliable performance and durability. Buyer beware: some motor manufacturers actually use aluminum windings with a copper coating in their motors which will last a fraction of the time that copper wound motors will last.Additional Motor Features:
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.
DUAL TIMER AUTOMATIC TANK DRAIN Eaton incorporates yet another standard value-added feature in it’s compressors that will eliminate maintenance and help to add years to the life of your air tank.In hot, humid industrial environments, there is typically a lot of excess moisture in the air that is consumed into the compressor while under the intake & compression cycles. This moisture can then be transferred to the compressor into the air tank.Additionally, if the compressor operates at a lower RPM and runs cooler (like our unit does) then water is condensed out of the air and collects in the air receiver. This water is harmful in many ways and must be drained out regularly.First, it robs you of air capacity in your tank. Secondly, this moisture can be transferred through air lines into your equipment and/or tools.Last, this water must be drained out regularly to avoid corrosion within your air tank which will shorten the overall life of your tank or worse yet result in tank failure.Eaton’s Automatic Tank Drain with Integrated Dual Timer will do this maintenance for you automatically on the time intervals you set to ensure that the condensation is removed regularly to avoid all of this.
CONTROLS & COMPONENTS We at Eaton Compressor use only top quality components on our compressors.
CONTINUOUS RUN & AUTOMATIC START/STOP Eaton Compressors come equipped with “continuous run” feature that maximizes performance and reduces wear on the internal components of your motor.Under heavy workload applications such as sandblasting, your compressor can cycle on and off many times per hour. This constant cycling is causing more wear on the magnetic contacts in the motor because they are arching as the motor starts and stops.If your workload is over 50% - 60% duty cycle we recommend engaging the continuous run feature to eliminate this “start & stop” arching and wear and tear on the magnetic contactors in your motor.For normal workloads in your shop, you can turn off the continuous run and the unit will go back to automatic start/stop operation.
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.
