BRANO Filter mats – for clean air and a healthy indoor climate!

Where are BRANO filter mats and non-woven filters used?

BRANO air filter mats are used for cleaning supply air and exhaust air in ventilation technology, in ventilation or air conditioning systems, ventilators, air cleaners, in forced ventilation systems for low-energy technology (with or without heat recovery) and in control cabinets, when the ambient air is heavily contaminated with dirt or dust particles. They are also important as pre-filters in motor protection hoods or as supply air filters. And - a particular field of applicaion for our non-woven filters - in varnishing, paint-spraying and drying systems.

What are the special characteristics of BRANO filter mats and non-woven filters?

BRANO´s high quality filter mats are manufactured from silicon- and PVC-free Polyester (PES) or Polyethyleneterephthalate (PET) non-woven materials, and hence absolutely environment-friendly. Further, as a textile fibre, PET has a number of highly useful features, because it is not very elastic, has high dimensional stability and hardly tends to crease. Our non-woven fabrics comprise progressive depth structure, i.e. the fibre density changes in cross section (decrease of the fibre thickness in the direction of air flow), so that coarser particles are caught outside and finer particles in the middle of the filter mat. Result: the air resistance does not rise so quickly, and – a welcome characteristic – the service life of the filter mat increases accordingly.

Particle filter classes in air filters, to DIN EN 779

These particle filter classes indicate the separation efficiency level for particles of a certain size or of other particles in the air or in exhaust gases. DIN EN 779 comprises 17 classes (Classes G1 to F9 for coarse and fine dust filters). BRANCO offers perfect coverage of the range G2 to M5 (coarse to medium dust particles).

Filter class G2 (coarse filter mats)
Pre-filters for high dust concentrations in ventilation and air conditioning systems (with low demands on air purity, e.g. in window-mounted air conditioners, supply air for cooling of switchgear etc., filters for coarse dust particles).
Filter class G3 and G4 (standard and fine filter mats)
Filters for supply and exhaust air ventilation technology, in ventilation or air conditioning equipment, ventilators, air cleaners and in forced ventilation systems.
Filter class M5 (fine filter mats)
Filters for fine dust separation in ventilation and air conditioning systems with high level of air purity, supply air filtering for sensitive switchgear, supply air for paint spray booths, pre-filters for particulate air filters.

Our non-woven filter mats are available as roll material and in individual customised sizes

If required, you can easily cut BRANO filter mats to size yourself, to meet your own particular requirements.

BRANO filter mats and non-woven materials guarantee separation of coarse and medium dust particles in the fields of ventilation technology and air conditioning systems.
