The surface is coated with a special anti-corrosion layer, which effectively resists common chemical substances and extends the service life of the pump body. The core distribution valve and directional valve adopt ceramic disc valve structure, which is wear-resistant, dirt resistant and does not require lubrication The membrane chamber has been optimized through simulation design to reduce air consumption, improve compressed air utilization, and effectively reduce energy consumption Built in exhaust chamber and muffler for dual noise reduction, while avoiding shutdown issues caused by condensation and icing Adopting a modular structure, the accessories have strong universality, reducing spare parts inventory and maintenance costs, and making replacement convenient.
