Features
Ningbo Yuxin Pneumatic Valve Co., Ltd. is one of the leading pneumatic air preparation unit manufacturers and suppliers in China. If you're going to buy cheap pneumatic air preparation unit, welcome to get quotation from our factory. All customized products are with high quality and competitive price.
| Introduction |
Generally speaking, the compressed air from the air source contains excessive water vapor and oil drops, as well as solid impurities, such as rust, sand, pipe sealant, etc. These will damage the piston seal ring, block the small exhaust holes on the components, shorten the service life of the components or make them invalid. The function of the Pneumatic Air Preparation Unit is to separate the liquid water and liquid oil droplets from the compressed air and filter out the dust and solid impurities in the air. Our products have various specifications and filter elements of different sizes, so they are widely used.
Features
The Pneumatic Air Preparation Unit is designed as a transparent container, so you can visually observe the internal conditions and control the capacity.
All copper filter element has good filtering performance, you can choose 5 microns or 40 microns.
Zinc alloy die-casting shell has good pressure resistance, wear resistance, and corrosion resistance.
The main components of the Pneumatic Air Preparation Unit include the regulating handle, air distribution block, oil drop regulating screw, pressure gauge, pressure reducing valve, oil mist collector, etc.
