HV1/2 Series Dental, EV, Oxygen Oil Free Compressor

NAILI HV series Oil free Piston compressors

Two-stage, double-acting reciprocating compressors with modern technology combined with robust engineering for reliability, durability and ease of maintenance, providing cost-effective, oil-free operation year after year.

Benefits

Improved carbon footprint

In oil-free compressors, there is no risk of oil contaminating products or equipment. In addition, the installation, energy and maintenance costs of condensate treatment, filtration systems or compressed air treatment are avoided. The result is a significantly improved carbon footprint.

Short payback times

High quality, robust construction and excellent efficiency mean that the payback time is very short. With its long economic life cycle, reasonably priced compressed air can be supplied year after year.

Easy installation

The units are ready for connection and are easy to install, requiring no additional foundations.

High air quality

The large size of the tube cooler allows water cooler technology to replace conventional oil lubrication. This ensures absolutely no risk of contamination and a class 0 air output.

What is an oil-free compressor?

An oil-free compressor or oil-free air compressor is a type of air compressor that does not use oil for lubrication. This type of compressor runs at a lower speed, which makes them quieter and more efficient.  

What is the difference between an oiled and an oil-free compressor?

Direct piston oil-free compressors differ from oiled compressors because they do not require oil to operate. Oil-operated air compressors are ideal for applications where high pressure and capacity are required. Oil needs to be added to the compressor to allow for higher RPM and to keep the compressor running at high speed. Oil-free air compressors do not require oil and are lighter in weight and easier to carry. This oil-free compressor is ideal for applications where noise and air quality need to be considered.

Oil free piston air compressor applications and industries

The laboratory, medical, electronics, dental and food and beverage industries benefit greatly from oil free piston air compressors because they are quiet and easy to maintain.


The Surface process and Piston seal O-ring IMPORTED from Germany 

which is most professional technology in this industry; 


We use the SPECIAL process with aluminium alloy on inner surface of cylinder in such piston compressor; 

Purpose to decrease the weight and improve the hardness(≥HV800) and abrasive resistance of surface 

at the same time under hone machining to guarantee the shade of inner hole with roughness of surface;
