Three-proof Polyester Needle-punched Felt Bag (waterproof, antistatic, oil-proof)
In the process of producing needle-punched felt,conductive fibers or conductive materials are mixed into chemical fibers. The filter cloth is rolled and imegnated with PTFE (waterproof agent),which is used in occasions with high moisture content .The filter material is not easy to block the paste bag,the service life of the cloth bag is prolonged,the gas flow rate is increased, and the maintenance cost is greatly saved.
The bag has the advantages of high void, good air permeability, high dust collecting efficiency and long service life, which are peculiar to common felt filter bags. It has moderate high temperature resistance, and can reach 130"C in an instant. It also has moderate acid and alkali resistance. and very good wear resistance.

Submerged Right Angle Pulse Valve
Product Description Pulse valves are divided into right-angle pulse valves and submerged pulse valves. Right angle principle: 1. When the pulse valve is not energized, the gas enters the decompression chamber through the constant pressure pipes of the upper and lower shells and the throttle holes in them. Because the valve core blocks the pressure relief holes under the action of the spring, the gas will not be discharged. Make the pressure of the decompression chamber and the lower air chamb...
