bag filter

Bag Filter

These filters usually can be used just to 260°C. Because of the distance between the compressed air storage with integratd membrame-closing-claps and the cleaned air channel a thermical isolation can be installed.

So powerful membranes are available for higher temperatures and a long endurance for these membranes and low costs for spare parts are the results.

cylindric filter

Bag Filter Cylindric Filter

The FAV-Cylindric Jetpulse filter can usually be used just to 260°C. Till a vessel diameter of 1300 mm round type Jetpulse filters are normally equipped with a swing around tube bottom. This bottom is to lift by hydraulical or mechanical forces. From a diameter of 900 mm FAV-Jetpulse filters have a clean air channel for inspection on foot. Special excecutions are possible in every case.

Filtermedia

The needled felt filter tubes are mainly made of synthetic fibre. The standard of a filter tube depends largely on the kind of the filter fibres. Special designed materials can stand very high running temperatures and are resistant against agressive chemicals.

Qualities and durability of a filter tube depends on composition, structure, surface treatment and the thickness of the material. Because of many years of practical experience in filter technology, FAV is your partner to check out the perfect combination of materials for your individual solution.

Filtertechnology

Filter Cleaning with Impulse Technique FAVORIT ECONOMY air pressure cleaning

The secondary air volume got increased at a constant consumption by optimizing geometric conditions of blast-pipe, venturi-nozzle and filter tube. Result: an improved drench activity. The tube gets drenched additionally effective after the air pressure push. Also the particles inside the filter get flushed safety. The result is a better, more intensive cleaning process of the filter tubes at a constant air consumption.
