Previous : Hydrogen Reciprocating Air Compressor
Nitrogen piston compressor is a product specially designed and developed for special gas media on the basis of our company's leading product oil-free lubrication air compressor.
In addition to the characteristics of the air compressor, it has been specially designed for the particularity of the compressed medium. The model has a compact structure, small size, beautiful appearance, stable operation, low specific power, and low noise.
The main features are as follows:
1. Absolutely sealed, the compressed medium does not leak, ensuring environmental production safety.
2. Using oil-free lubrication, the compressed medium does not contain oil, does not react, and maintains the original gas characteristics.
3. Equipped with gas recovery device to avoid gas loss.
