Fresh Oil-Lubricated Rotary Vane Compressor - L-GK 20-100

Features

• Single-stage, air-cooled compressor for compressing purified gas
• Note: permissible H2S content up to 4,000 ppm depending on application
• The rotary vane gas compressor complies with Directive 2014/34/EU
• Suitable for transporting explosive gases and vapors in explosion group IIB, temperature class T2 in zone 1. It can be operated in zone 1.

Design

Compact unit with acoustic hood and cooling air blower.

• All components are mounted on a main frame
• Rubber-metal bonded elements to reduce vibrations
• Electrical control panel wired to terminal boxes
• Can be installed without the need  to provide a foundation

Compressor Stage

Rotary vane compressor stage with

• Fresh oil injection cooling
• Multi-cell design principle
• Direct drive via elastic coupling between the drive motor and the compressor stage
• Suitable for compressing purified gas
• Outstanding operating reliability
• Dynamic oil film between the rotor vanes and the inner wall of the compressor housing
• Low rpm and self-centering rotor

Gas Path

The gas flows through the suction line to the compressor stage. Here it is compressed as a result of the increasingly smaller volumes of the compression chambers. The compressed gas exits from a compression fitting on the compression stage through a check valve and enters the compression-side piping system.

Cooling

The compressor is cooled by a separate cooling air blower in the acoustic hood. The intake cooling air flows through the acoustic hood from the bottom to the top and is discharged to the outside through the discharge air hood.

Drive

The compressor is driven by a built-in electrical motor via  V-belt.

Safety Equipment and Display

• Check valve on the pressure side
• Contact pressure gauge to monitor the compressor pressure, with two electric switching contacts, measuring range: 0 to 4.0 bar
• Contact thermometer to monitor the outlet temperature, with two switching contacts, measuring range: 0 to 300 °C
• Emergency stop switch to shut off the compressor in emergency situations
• Terminal box (Exe/Exi) for  wiring of electrical components
