Edwards ITF20K Inlet Dust Filter - A44215000

The ITF inlet dust filters prevent the entry of dust particles into the pump. The impedance of a clean filter reduces the pumping speed of a 20 m³h^-1 pump by about 20% at 1 mbar and 25% at 10 mbar. 

Depending on your application, you can normally clean the filter element with a vacuum cleaner or a clean air blast, and then re-use the element.
