Quincy Oil-injected Screw Air Compressor QSI

A rotary screw air compressor enacts positive displacement using twin spiral screws. An oil-flooded system, the more common type of rotary screw compressor, fills the space between the helical rotors with an oil-based lubricant, which transfers mechanical energy and creates an air-tight hydraulic seal between the two rotors. The atmospheric air enters the system, and the interlaced screws push it through the compressor. Quincy Compressor manufacturers a full line of industrial-sized rotary screw air compressors built to meet the demands of your business. Check out the full line of rotary compressors below.

Product Description

There are many advantages of rotary screw compressors. They are the compressor of choice for a wide range of compression applications across many industries:

  • Continuous airflow and pressurization: Many air compressors generate excess heat and need to cycle off to maintain the machinery. Rotary screws can turn continuously and experience little to no downtime.

  • Easy maintenance: Some rotary screw systems are manufactured with up to 70% fewer parts than other compressors. This design drives down maintenance costs.

  • More power: Rotary screws have extremely high airflow rates. They can run tools and heavy equipment efficiently with impressive horsepower.

  • Safer at extreme temperatures: Many rotary screws can pressurize air in both high and low temperatures.

  • Energy-efficient: Rotary screws produce less heat, conserve more energy and consume less oil than most compressors. These features preserve the machinery for many years and keep the lifetime cost of the compressor low.

  1. Air enters the compressor through the inlet valve.

  2. Air then travels through the pressure control line and into the regulator valve. This process sets the air pressure for the system.

  3. Both oil and air enter the compressor, where they combine into a mist. Air travels the length of the matching rotary screws and becomes compressed.

  4. After exiting the compressor, the air and oil mist enters the primary oil separator tank. The tank uses centrifugal force to make the oil molecules come together, forming droplets that fall to the bottom of the tank. The oil can then be recycled into the air compressor for the next batch of air.

  5. The air then enters a secondary separation filter, which further purifies the air and removes more of the oil.

  6. The oil-free air then exits the system, into a reserve tank or the connected air tools or machinery.

  7. The oil travels from the separator tank to an oil cooler. Next, it goes through a filter that removes any debris and is then returned to the air compressor.
