An essential parameter of the filter apparatus is the surface of the filter. It often is not identical with the total filter area. The usable filter area AF is the quotient of the air-quantity and fitration speed.

The extreme-area is between 0,2 and 0,5 m/min or 2,5 and 4 m/min. The usual pressure-loss at the filter lies between 50 and 200 mmWS.

There are different factors influencing the operation performance of the filter units. A few aof them are listed below:

• physical properties of the filter media, e. g.: cracking pressure air permeability
• dust, bulk material and their properties, e.g. bulk density, chemical composition etc.
• carrier gas , e.g. air volume, temperature, pressure and relative moisture
• construction of the filter apparatus, e.g. form of regeneration, geometry of the star filters
