Single-Phase Rotary Screw Air Compressors

Ingersoll-Rand rotary screw air compressors are used for compressing large volumes of high-pressure air or operating high power air tools. They are ideal for chillers, jackhammers and impact wrenches. They feature a smart controller for monitoring system pressure, providing multiple parameters for quick adjustments & increasing equipment uptime. They come equipped with rugged motors for extra toughness and Poly-V belt drive system for reducing friction loss & maximising airflow output. These single-phase rotary screw compressors are available in a pressure range of 125 - 150 psi on Raptor Supplies.

Working Mechanism

  • These compressors have two interlocking helical screws / rotors that turn in opposite directions inside a casing.
  • The rotors have a specific profile, allowing them to mesh together closely without touching each other.
  • As the rotors turn, the air gets drawn in through an inlet port and gets trapped between the rotors and the casing.
  • As the rotors continue to turn, the air volume between them decreases, which causes compression.
  • The compressed air is then forced out through a discharge port into a storage tank or a pneumatic system.

Frequently Asked Questions

How to maintain these rotary screw compressors?

Regular maintenance involves changing filters, checking & adjusting belts, inspecting & cleaning the cooling system and monitoring oil levels & quality.

How to select the right rotary screw compressor for my application?

Consider factors like required flow rate, operating pressure, duty cycle and ambient temperature of your application.

What are some safety considerations when using a rotary screw compressor?

Proper installation, regular maintenance and following the manufacturer's recommended safety procedures are ideal for the safe operation of these rotary screw air compressors. Also, wear appropriate personal protective equipment (safety glasses & hearing protection) when working with the compressor or operating pneumatic tools.

What are some tips to reduce energy consumption with a rotary screw compressor?

To reduce energy consumption with a rotary screw compressor, optimise the compressor's operation, use variable speed drives and reduce system leaks.
