Stainless Steel Explosion-Proof Oil Purifier is mainly used in aviation maintenance enterprises, used to filter gasoline, kerosene, oil and hydraulic oil. It is also used in other places where explosion-proof requirements are high.
Characteristics of Stainless Steel Explosion-proof Oil Purifier, 1. The use of circular arc gear oil pump, with low noise, stable output, smooth operation.
2. Electrical appliances, motors are explosion-blown components. It can also be used as a power
purification source for flushing machine.
3. Stainless steel mirror shell appearance beautiful, piping system and components using stainless steel material, high filtration efficiency.
4. Filter filter precision is high, the pollution ability is strong, the filter cartridge service life is long.
5. The panel is fitted with a pressure gauge, which continuously indicates the operating condition of the system and the degree of contamination of the filter cartridge at work.
