Two Stage Screw Compressor With PM Motor (VSD)
Keeping your production up and running leeair. compressors ensure long and trouble-free lifetime at the lowest operating cost.
Reducing your production costs
The innovative design of leeair compressors reduces your energy bill and overall compressor life cycle costs.

Two stage Air Compressor
The bearing load is greatly reduced.Improved Air-end longevity. Reduced maintenance.
2-stage air compressor can set the pressure ratio of three to one between first and second stage so that it can reduce internal leakage, and each pressure ratio of the 2-stage air-end is much lower than that of single stage air-end. So it improves pressure efficiency significantly.
After compression of air in the first stage, the air is cooled down by intensified oil injection cooling which reduces the intake air temperature of the second stage. As the results, the process of air compression is done by isothermal compression which can reduce energy consumption.
Through the optimization of volumetric efficiency and adiabatic efficiency, 2-stage air compressor can be obtained 15% more air volume compare to the same power of single stage air compressor

Low Pressure Screw Compressor With PM Motor (VSD)
Cost Saving by leeair. Low Pressure Compressor
Normally in the industries such as textile, cement, chemical fiber and glass production, required pressure for air is lower than 5bar. leeair Low pressure compressors which are available for providing low pressure range 2~5bar with much increased air flow compared to 7~8bar normal compressors enable customers to have remarkable cost saving up to 30%.

Fully redundant oil and air separation treatment system.
Large displacement air compressor is more suitable for dual oil and air separater tank

Application Scope
The new L-PL series has already passed the test runs in real conditions with flying colors.
As diverse as the operating conditions may be – its robust technology, low maintenance needs and the pioneering achievements to maximize efficiency will let it quickly win over friends wherever a reliable compressed air supply is indispensable.
leeair. Low Pressure Mechanism
Through application of big rotor and direct connection between motor and air-end , it is able to achieve low speed running and ensure high performance.
And leeair unique design of air oil separator tank guarantee the outlet oil content less than 3ppm or even equal.

Optional online maintenance system

Water Lubricating Oil free Single Screw Air Compressor
leeair ® L-series oil free single screw air compressor use water for lubricating.
The water after filter system can satisfy the drinking water standard so the air compressor can output clean compressed air.
Water in oil free compressor achieves the effect of lubricating, cooling, sealing and noise reduction. Water also facilitate the ideal isothermal compression process.
The discharged water require no special treatment which is environmental-friendly.
Best energy saving and lowest maintenance cost
Single screw is widely used in air compressor. It consists of a single main screw and two vertically-aligned star wheels. The rotator is uniform loaded, and the two star wheels are symmetrically positioned around the axial of main screw.
The dynamic balance achieved by this scheme can reduce the load of screw and reduce the working noise.
leeair ® provide clean, oil-free and pollution-free air compressor, the zero emission pollution treatment can effectively protect the environment.

For low temperature compression (45 degrees), easy line filter and water changes.
Production of low temperature clean air supply. No oil is used so no need for waste oil treatment. The permanent magnet motor is adopted to make the rotating speed change faster and the efficiency is higher than the induction motor, so the efficiency of the air compressor is greatly improved.

Quietness
Without thrust load on the axis direction of the rotor, the force in the circumference direction rotates quietly with good balance. As a result, the load on the bearing is reduced, minimizing the generation of noise or vibration.

Durability
The gate rotors follow the rotation of the screw rotor along its gear.
The water film formed on the screw rotor’s gear and the free floating mechanism maintain the high efficiency for a long working period.
High Efficiency
Since the lubrication water is jetted during the compressing process, the compression is done smoothly under almost even temperature, realizing ideal, safe and highly efficient compression with slow rotation.

Stable Air Delivery
Depending on the valve of pressure sensor, the digital controller change the motor rotation speed through inverter.
That is how it controls
The discharge air pressure to make stable air output.
