Filter Pads And Rolls / Luftfilterplatten Und -Zellen

Air-filter pads and rolls are made from synthetic, glass, or natural fibres. They are used for special application areas in ventilation and climate-control, to include the following: controlled-condition cabinets; air-intake filter systems for fans, compressors, and motors; filter systems for motor combustion air; and in room-air treatment systems.

Bag Filters / Taschenfilter

Bag filter is composed of several filter bags. The individual bags, made of micro-fibreglass fleece, have been shaped so as to provide wedge-shaped filter bags. The spacers in the individual filter bags ensure complete utilization of the full bag depth and, in turn, of the entire filter surface. The spacer seam is sealed. The ready-to-install filter bags are secured to sturdy U-shaped profile frames (25 mm) by clamp fittings.


High efficiency submicron particulate air (HEPA) filters consist of special, paper-like fleece made of superfine micro-glass fibres that have different filtration and air-flow capacity depending on the filter class. 

The filter fleece is processed to form a stable package of folds; number and height of folds are designed for maximize product life and to match the optimal rated operating points and long service intervals.

The individual folds are separated down to the entire depth by continuous synthetic threads (hot melt) that are bonded together, which provides great stability and even thread runs as a result of the compact fold structure.

The packages of folds are cast airtight in robust frames. A number of different framing material is available:

- MDF, Plywood, Aluminium, Galvanized steel,  Stainles steel

High temperature (HT) filters

HT filter cartridges are made of deep-folded fleece of paper-type microfibers. The position of warehouses is stabilized by:

  • corrugated aluminum separators (versions F, T, H, E, G, S)
  • the warehouses are separated by strips of filter material
  • separators are designed for air flow on both sides.

The filter element is dry-inserted into a riveted filter frame made of galvanized sheet metal or stainless steel equipped with protective grille on both sides. None of the materials used contain silicone, which meets the requirements of surface technologies, and all are thermally stable up to at least 250 ° C. The filter inserts are equipped with a circumferential sealing tape made of glass fiber. The design flange has a thickness of 25 mm. All MultiTherm filter inserts are equipped with a protective grille as standard (galvanized sheet steel, optionally stainless steel).

Compact & Panel Filters / Kompakt- & Paneelfilter

Compact filters are made of micro glass paper which is pleated into folds to form extremely stable filter packs. The number and height of the pleats are optimally designed to match the operationg conditons of the filter element.

Carbon Filters / Aktivkohlefilter

Activated charcoal cartridges are inserted into mounting frames of air handling units. The cartridges guarantee a large contact surface in combination with a small approach flow cross section. They are replaceable as well as regenerable. The cartridges are employed in technical systems for air conditioning to adsorb harmful gases and smelling substances.
