    HUSH-QUIET_Logo.jpgBendPak’s Hush​-Quiet RS7580H​-603 rotary screw air compressor is designed to tackle the compressed air needs of any kind of automotive shop or facility. It's an exceptional product in a world of copy cats, but the thing that really stands out about the Hush-Quiet series is what you don't notice. That is to say, a whole lot of noise. Our exclusive Hush-Quiet technology makes the RS7580H-603 the perfect compressor to install in noise conscious service areas.

    Rotary screw air compressors have become a popular source of compressed air for industrial applications. ​The principle is simple: air enters a sealed chamber, where it is trapped between two contra‐rotating rotors (Asymmetric Profile screws). As the rotors intermesh, they ​rapidly reduce the volume of trapped air to deliver it compressed at the desired pressure level.

    When this simple compression concept is combined with continuous contact cooling, the rotary screw air compressor operates with temperatures approximately half of those generated by a typical reciprocating piston compressor. This lower temperature enables the rotary screw air compressor run at full load, 24 hours a day, 365 days a year. So if your automotive facility or shop has extraordinary compressed air demands, the Hush-Quiet RS7580H-603 rotary screw air compressor is the absolute ideal industrial application for all your needs.

    How the RS7580H‐603 Rotary Screw Compressor Works
    The asymmetric profile screw set is driven by a 7.5‐HP electric motor and triple‐belt drive. Atmospheric air is drawn through the inlet filter into the asymmetric profile screw set. Here is where the air is compressed. BendPak's specially devoloped PowerCool synthetic lubricant is injected into the screw set to serve three important roles: coolant, lubricant and sealant. Under normal conditions the air reaches a maximum temperature of ​around 80°C during compression. ​Then the dual‐stage separator removes ​any cooling fluid from the compressed air. The cooling fluid is recycled, passing through the cooler, the micro‐filter and all the way back to the point of injection. Meanwhile, we regulate and optimize the air and fluid temperature with a clever thermostatic valve.The air emerges from the separator cartridge with a ​total fluid content of less than 2 mg/m³ before passing through the minimum pressure check valve and, at last, through the after-cooler. In the after‐cooler, we further reduce the air temperature between 5 and 10 degrees above ambient. Most of the moisture in the air condenses here and is easy to separate and remove in the downstream centrifugal separator. Now, the air can finally leave the compressor via outlet and applied to any automotive job you need.

    ​More Than Just a Simple Screw
    BendPak's asymmetric rotor profiles with precision ground lobe configuration provide higher compressed air ​output without trading for higher power consumption. Each rotor is fitted with high‐precision bearings allowing ​for a significantly increased air end life. Multiple shaft seals are also there to provide total protection from oil and other contaminants. Finally, toothed safety washers and a special locking nut ensure that the rotor tolerances are set throughout the life of the unit for improved reliability, stability and longevity.

    True Trouble-Free Operation
    With no ​parts to wear down, the RS7580H‐603 offers ​superior reliability and significantly reduced maintenance costs. Simply, there are no piston rings, valves, rod‐inserts, bushings and pistons just waiting to fail. There are no valves, valve plates or valve strips to service. With extended service intervals, you can save time and money. ​And convenient service panels allow you to easily access all the necessary internal components for occasional servicing. All regular maintenance can be performed from the comfort of your own shop at your leisure. But we do provide annual maintenance contracts for customers who​ prefer the assurance that their QRS compressor is always operating at peak performance. Ask for details.

    Reduced Long Term Operating Costs
    This is a big deal. Energy costs ​represent a significant portion of any compressed air system's total lifetime cost. In fact, the amount of energy required to run a traditional compressor for just one year can exceed the compressor purchase price! Over a period of 10 years, energy normally totals 70% of the overall costs. The efficient design of the BendPak Hush‐Quiet RS7580H‐603 rotary screw air compressor can reduce this burden significantly.

    Revolutionary Control
    Our easy-to-understand touch‐pad control automatically regulates and monitors ​the rotary screw air compressor via an industrial-​grade PC with real-time operating system. The four‐line, plain‐text display with touch keys and menu‐guided screens offer users clear function choices. At the same time, the controller manages the system​ by monitoring temperatures and pressures in order to protect your investment ​and ensuring you extract maximum energy efficiency and performance from every single kilowatt you use.

    Running Cool

    When designing the RS7580H‐603, we paid great attention to providing a ventilation and heat exchange system that guaranteed excellent cooling​ in even the harshest environmental conditions. With efficient, high-capacity cooling fans and oversized cooling intakes and discharge ducts, we're happy to report we've surpassed our own expectations. And we'll surpass yours, too.

    PowerCool Lubricant
    PowerCool lubricant is a specialized synthetic coolant ​engineered to achieve peak compressor performance for rotary screw air compressors. The unique PowerCool ​formula allows for long life, excellent cooling performance and improved compressor efficiency.
    • Two years/8,000 hours useful life, saving you money on cost and disposal
    • Low carryover up to 75% lower than mineral oils and PAOs, which means less fluid for makeup and less contamination.
    • Superior compressor performance means lower cost benefits due to excellent cooling and efficiency.
    • Lower maintenance costs, because PowerCool lubricant can be changed up to eight times less often than most other lubricants
