Air Screw Compressors

GODREJ LUBRICATED SCREW AIR COMPRESSORS- GL SERIES


Highly Efficient GRD Rotors

GRD series rotors are highly efficient and world renowned for their 5/6 profiles which has evolved from previous generations to meet today`s market requirement – “Energy and cost efficiency with greater capacity”

Lower inter-lobe leakage losses: Greater the number of lobes, smaller is the pressure difference between the two neighbouring working chambers. Thus, inter-lobe leakage losses are reduced. Hence leakage to delivery ratio decreases as the number of rotor lobes is increased.

Larger wrap angle & discharge port: Furthermore, more lobes combined with a large wrap angle ensure multiple rotor contact. This reduces vibration & thus minimizes noise. Larger discharge ports decrease the discharge velocity and therefore reduce the discharge pressure losses, thereby increasing the compressor overall efficiency.

Larger rotor size: To increase the rotor throughput, Air-End of our Air Compressors are of larger size.  Our Air Compressors built with 5/6 profile with larger rotor size than the traditional profile consumes lower specific power (kw/cfm ratio).

Versatile Package Control System

Minimum pressure check valve assures continuous pressure for lubricating the compressor, reduces fluid foaming and protects the air-fluid separator element.

 

Integrated Microprocessor Controller

User friendly interface

Constant readout of discharge pressure, motor current and air/oil temperature.

Selective readout of all operating and maintenance parameters.

Safety shutdown.

Provides 24 hours automatic start-stop operation.

Lead-lag and sequencing with multiple compressors.

Maintenance reminders.

Electrical Control Protection

Protection against ‘Single phasing’

Phase sequence protection

High discharge temperature shutdown.

Auto-dual control: If there is no system demand during the pre-set time delay, the compressor will shut down the drive motor. The controller will restart the compressor when system pressure drops to the preselected pressure level.

High Efficiency Drive Motors

IEC high efficiency TEFC IP55 motors.

High temperature F class insulation rating

Direct coupling design for extended bearing life

Easy maintenance with grease refill port.

No load start protection. Automatic blow down during unloading before the unit shuts off ensures the unit does not start under load.

Superior Filtration System

Ultra efficient inlet air filters provide clean air that traps dirt particles to less than 3 microns.

Easy Spin on Oil Filters.

Pressure differential gauges for easy filter maintenance.

Compressor Model No.
