Original Mitsui Seiki Air End Stainless Steel System. 100% Oil Free; Maintenance-free compressor; Reliable operation; Small energy consumption; Long life, 24 hours online.

Oil free screw air compressors are widely used in industries that require high quality air sources such as: pharmaceutical, food, electronics, chemical, packaging, etc. 100% pure compressed air is a necessary procedure to guarantee satisfactory crafts and product quality, which ensures the production of high-end products safely and risk-free.

The lubrication system of an oil free screw air compressor is an individual fuel recycling unit. The compression chamber and the bearings were separated by a set of sealed high-performance mechanical assembly. The lubricating oil can only flow in the enclosed area and is prevented to enter the compression chamber, which only contains 100% pure compressed oil-free air. The users could obtain 100% pure compressed air with some slight post-treatment of water and dust removal.

Advantages:

1. True Energy Saving:

Oil free water lubrication screw air compressor is a kind of compressor that provides clean, pollution-free, 100% oil free screw air compressor, its zero emission can protect the environment efficiently.

2. Water – Lubrication, Sealing and Cooling:

Ideal isothermal compression. High efficiency (large air delivery) Low temperature compression. No need for a after cooler Low rotation speed. Low noise, low vibration and Low viscosity of lubricant – water. Easy to be separated with the air.

3. All stainless-steel pipes:

Simple, non-corrosive, non-polluting, high reliability.

4. Single Stage Compression, High Efficiency, and Energy Saving, and Easy Maintenance:

Single stage compression makes the structure easy. Compression efficiency is higher than the two-stage dry air compressor.

Less consumable parts, easy to be disassembled, reduce the maintenance cost and time greatly.
