oil free air compressor
Achieve ultra-high compressed air quality and highest energy efficiency
1. The surface of rotor and base shall be treated with GHH patented special coating. Compared with other coatings, GHH patented special coating has a longer service life and can save 10% of the main engine energy consumption.
2. The second stage rotor is made of stainless steel, providing users with superior anti-corrosion performance.
3. Stainless steel and aluminum alloy pipes are selected to connect the intercooler and the stainless steel secondary rotor. Condensate generated during the intercooling process will not corrode these materials, and can prevent the generation and falling of rust, thus extending the service life of the coating and rotor.
4. The cooler shell is also made of stainless steel to effectively prevent the corrosion of cooling water.
5. The internationally famous Marathon high-efficiency motor is adopted, with the protection grade of IP55 and insulation grade of F, which is durable.
6.High efficiency air filter, dust and particle content reduced to 10 μ Below m, 99.9% dust removal efficiency can be achieved.
