Greekn H.I. Variable Speed Drive Screw Air Compressor GA55VSD 55kW 75HP Oil Lubricated Type Screw Air Compressor

Company introduction

The Greekn H.I. company covers a construction area of 25,000 square meters, the factory covers an area of 15,000 square meters, more than 100 employees, including more than 60 workshop technicians, 10 R & D engineers, more than 20 sales team.Our specialization lies in screw air compressor technology. We are fully committed to providing customers with highly effective air compressors and dryers to help customers achieve optimal performance in even the most challenging conditions, like tropical areas with high-temperature operation. Our products help lower the consumption of electrical energy without sacrificing performance.

Original air end with large air capacity

The air compressor is equipped with asymmetric male and female rotors and they have two prominent advantages over the other rotors:

As the gear tooth profile of the rotor consists of an arc and arc envelope, a "convex-concave" seal is achieved between the rotors, which helps to produce hydrodynamic lubricant film and make the compressor more efficient.

Speed of this air compressor is 30-50% lower than that of other air compressors, due to the large rotor and bearing. The rotor and bearing also reduce noise, vibration and effects caused by impurities and carbides on the rotor and ensures a longer service life.

High efficiecy motor

The highly efficient motor meets IE3 standards with an energy efficiency up to 93%.

Thermostatic valve

Sense the temperature of oil by thermostatic valve,protect machine from over-heating.

Oil separate tank

Triple stages of separator can effectively reduce the oil content to less than 2ppm.

Patented design of inlet valve

Sinking gravity sensor oil stop valve,effectively stops the oil reverse and largely reduces the inlet obstruction loss.

Controller

Triple stages of separator can effectively reduce the oil content to less than 2ppm.

Oil separator

Multi-grade oil separator,the oil content of fine public 2ppm pollution minimum and required minimum maintenance.

Air filter

Triple stages of separator can effectively reduce the oil content to less than 2ppm.

Large cooler

Combined design of air cooler and oil cooler.A higher level standard makes the compressor run in ambient temperature 55 centigrade.

Centrifugal fan

An optional backward curved centrifugal fan uses an impeller to increase air flow.In addition,during the operation the centrifugal fan features no friction,low noise,no dust and easy maintenance.

Inverter

Energy saving 20%-30%

Highly-efficient PWM inverter:

Keep constant discharge pressure.

Lower the sudden current of launching.

Adjust the motor rotary speed to produce air according to the demand.

** The GAVSD series compressor can run in two mode,variable speed mode or fixed speed mode.
