Greekn H.I. Air Compressor GARL37 Locomotive Use Screw Air Compressor 37kW Air Compressor For Train

GARL series locomotive use screw air compressor

Installed with oil heater

Greeknhi's GARL series air compressor is designed for cold region 50 degrees below zero. This series features with oil heater in the oil separate tank, thus ensuring the air compressor will not fail during cold temperature operations.

Small in size

Greeknhi's GARL series is special designed for locomotive,smaller size,less space taking,easy to move.

Three stage oil-gas separator

This three stage oil-gas separator is made independently by Greeknhi and has won a national patent. It includes three stages: centrifugation, sediment and filtration. It can provide high quality compressed air with an oil content less than 2ppm.

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 quality air end bearing

Greeknhi GARL series compressor uses SKF bearings. It features a stable operation and is applicable to variable working conditions, ensuring the motor a longer service life.

Highly efficient drive system

It is an integrated drive system without a gear. Using a 1:1 direct connection drive, there is no production loss, making it an ideal drive system. It combines the motor, coupling box and air end as a whole to ensure compressor efficiency and center alignment of motor and air end when they are installed or during operation.

Special motor for air compressor

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

Special design for locomotive use

Greeknhi's GARL series compressors are reliable air source for the locomotive braking system.We have redesigned the overall structure of the air compressor to meet dimensional,voltage, frequency and operating system specifications according to the customers requirements.
