Precoat filters

Precoat filters (AS, AST, ASG)

Precoat filter with wet discharge, type AS

Conventional precoat filtration with wet discharge; the sludge is treated by secondary filters.

Precoat filter with dry discharge, type AST

Advantages are the small space requirement, no secondary sludge treatment required, dry filter cake discharge and wear-free cartridges.

Electroplating precoat filter, type ASG

Cleaning of electroplating baths (acid baths), treatment of saline solutions during electrochemical processing and treatment of other aggressive media.

The dimensioning of precoat filter systems is adapted to your application, for example in terms of design, individual dimensions, other materials and customer specifications.

Application areas

FAUDI precoat filters are used when the highest demands are placed on filtrate quality, e.g. in amine filter systems and in ultra-fine filtration. All filter types are available in a compact design.
For applications in the chemical, oil, gas, life sciences, food & beverage industries and for many other applications.
Use as a prefilter.

Filtration capacity

This is dependent on the filter size and the filter medium. The modular design makes it possible to adapt the filtration capacity to suit individual needs. Filtration capacities from 5 m³/h to 500 m³/h are possible.

Precoat filters

With a filtration capacity of 15,000 l/min and a filtration fineness of 3 µm, in use by the largest automotive supplier worldwide.
