Premium Efficiency Motors for Comair Oil Injected Screw Compressors
All Comair oil injected screw compressors are driven by IE4 premium efficiency electrical motors, whose efficiency could be over 96.3%. They are also of IP55 high protection grade, insulation class F and B rise. No matter how harsh your working environment will be, they are designed to supply continuous reliable operation.


Patented Air End Guaranteeing Unrivalled Efficiency
Comair’s patented air end is the key to high efficiency and long reliability for your oil injected screw compressors. Our new improved rotor profile ensures very little leakage of compressed air from the high pressure side to the low pressure side; optimized in and outlet portals could minimize the pressure losses; both male and female rotors are made of stainless steel with thermal treatment for good strength and toughness.
Heavy Duty Air Filter Protecting Your Oil Injected Screw Compressor
Comair oil injected screw compressors are using a heavy duty air intake filter protecting the compressor parts and removing 99.9% of dust particles over 3 microns; it supports long life cycle with 4000 maintenance hours; moreover, our air intake filters are equipped with pressure drop indicator, which could remind us the time for replacement.

An oil injected screw compressor might be the most widely used type on the market now. In the air end, when compressing is happening, lubrication oil is also injected inside to take away the compressing heat, to lubricate the bearings and rotors, to seal the very small gas between the rotors as well as to minimize possible generated noise. It is used in applications or industries where the compressed air quality doesn’t matter much.
No matter whatever kind of oil-free compressors, the main difference lies in the air end lubrication. Except for the oil free water lubricated compressor, it uses water to lubricate and to cool down the compressing chamber. For all the other types, there is no lubricating liquid at all. Oil free compressors are widely used in industries and applications where the compressed air quality affects the end products or the production facilities.
Comair oil injected screw compressors are designed and renovated after listening to our clients’ requirements and concerns. Their main advantages are as followings:
Low total cost of ownership: with the electricity cost being over 80% of a compressor total lifecycle cost, all Comair oil injected screw compressors are designed being energy efficient, especially with VSD technology;
Easy service: All the internal parts and filters are easily accessible. The maintenance work could be completed within a couple of minutes, greatly reducing the related downtime.
Low oil content: with our efficient oil gas separator, the oil content in compressed air could be limited to below 2 PPM. This could effectively protect the pipelines and other production facilities.
Oil injected screw compressors are gradually replacing piston compressors as the most widely used type. They could be seen almost in every industries including Aquaculture, Automotive, Brewery, Carbon Capture, Cement Production, Chemical & Petrochemical, Food & Beverage, Fertilizer, Glass Manufacturing, Metal Production, Mining Exploration, PET Bottle Blowing, Oil & Gas, Pneumatic Conveying, Power Generation, Pulp & Paper, Textile, Winery etc.
We can follow three steps in choosing the right compressor size for a factory.
Oil free or oil injected: check carefully whether the compressed air quality shall be oil free or not. Whether the tiny amount of lubrication oil in compressed air will affect your end product is the key to determine the compressor type.
Working pressure: check the compressed air consumption equipment. What pressure it requires. If it requires a pressure of 8 bar, we can suggest the compressor to discharge 8.5-9 bar.
Air capacity: check the compressed air consumption equipment and get the total required amount. If the total calculated amount is 8 m3/min, we can choose a compressor with air capacity of around 9 m3/min. We can leave around 20% as the fluctuation amount.
Comair oil injected screw compressor price vary greatly. The smallest will cost around 1,000.00USD while the largest one may be over 200,000.00USD.
