Modular filters

ProTechCon modular dust filters are bag filters. Modular filters can have up to 30 single or double modules, and with various discharge systems: silo, blow through, bag emptying, rotary valve, screw or chain.

They are made of 1.25 and 2 mm galvanised sheet metal.

The standard filter medium is PE40/PE25 bags. The filters are available with different bag lengths, depending on requirements.

The fire damper has a 69°C thermal protection fuse and microswitch connected to the plant's main fan.

The number of fire dampers and doors depends on the number of modules. See table..
