High-performance pocket filters

These versatile filters are used for diverse applications and contain synthetic filter media, which are also available in custom sizes. Pocket filters are the right choice for many applications in hospitals, offices and salesrooms, the chemical, optical, electronics industry, and for nuclear technology. These ultrasonically welded filters are optionally available with an integrated spacer and, on request, with a pre-filter layer for coarse dust separation as well as with metal, plastic or DRW quick-release divider frames. Our pocket filters are available in the following filter classes: coarse-dust and fine-dust filters G3 to F9.

Compact filters

Compact filters in a V-pack or panel filter design are used wherever there are stringent requirements with regard to air purity. They are mainly used to filter out coarse and particulate matter such as spores or pollen. These filters are used as pre-filters, main filters or as combination filters with an activated carbon layer and are also available in biostatic designs. The filter medium consists of a synthetic, pleated material, which is stabilized with glue beads and enclosed in a sturdy plastic frame. Compact filters are used in industrial, pharmaceutical, and food applications. They are dimensionally stable, pressure-resistant, and energy-efficient – and contain a large filter surface despite their small footprint. Their high dust-holding capacity prolongs the filter’s service life. Compact filters can be used as an alternative to conventional pocket filters.

In addition to air-conditioning and ventilation technology, we serve various sectors with this filter range, such as industry, energy, general construction, and room ventilation technology. Available upon request with EuroVent certification.


Where are these filters used?

Air filters are installed in all ventilation systems. And our product range covers each and every one of them, both in public and commercial buildings. Our filters are used wherever ventilation systems ensure a pleasant indoor climate and protect people and their health – whether in the field of ventilation, heating or air-conditioning technology.


Types of air-conditioning and ventilation filters

The most common and widely used products are traditional pocket filters with plastic or metal frames, as well as cassette and compact filters. From the ground up, we provide inherently rigid pocket filters that offer uniform, optimum flow rates at low differential pressures.  

For more challenging requirements, we can supply pocket filters with special spacers and V-shaped designs to further reduce the pressure losses in the system. In addition, multilayered filter media are used to maximize the dirt pick-up and dust-holding capacity. Modern nanomaterials offer significant energy savings and thus cost reductions compared to the traditional filter materials of recent decades.


Advantages and mode of operation

The purpose of every filter is to separate particles to the degree specified in the respective standards, which is referred to as the “retention rate”.
Pocket filters are usually fabricated by means of sewing or welding, depending on the filter material (synthetic fiber or glass fiber). Ensuring the correct installation position of a pocket filter – with the pockets always upright – is a prerequisite for trouble-free operation with minimal pressure loss. For all filter types, such as bag, panel or compact filters, careful attention must be paid to the filter’s orientation and installation location. The markings indicating the air flow direction must be observed. In addition, it is important to regularly check the unit for damage if the gaskets have been used more than once. This is the only way to be sure that the filter will work properly.


The mode of operation of a filter, regardless of its design, is always the same. Particle separation takes place between the upstream side (= dirty side) and the clean side. Depending on the application, surface or depth filters may be used. Using the traditional pocket filter as an example, the air to be cleaned passes through the pockets from the inside to the outside. Depending on the plant or application, it usually makes sense to filter the air via multiple filter stages. The first filter stage, the pre-filter, traps the coarse dirt and thus protects the highly effective fine filter from excessive dust loads, thereby extending its service life.



Filter cells / filter cassettes / Z-line filters / panel filters  

Filter cells, also known as filter cassettes, Z-line filters or panel filters, are flat, compact filters that are used in air treatment, air conditioning and industrial systems. They consist of progressively structured filter media made of synthetic or glass fibre materials, which are installed in a stable cardboard or plastic frame. Filter cells are often used as pre-filters or intermediate filters in multi-stage filtration applications and improve air quality by removing coarse dust particles. They are easy to install and replace and can be disposed of in an environmentally friendly manner as they are completely incinerable. Depending on the application, stabilising fabrics and other covers can be used to protect the filter fleece. Filter cells are ideal for applications where high indoor air quality and comfort are required and are often used in the 2nd second filter stage to filter finer particles. They have a shallow installation depth compared to conventional compact filters and are well suited for industrial ventilation systems and as preparatory filtration in clean rooms.

Pocket filters / bag filters  

Pocket filters are versatile air filters that can remove coarse and fine dust from the air. They can be used as pre-filters or main filters in painting and ventilation systems, air conditioning systems and general ventilation systems for industrial applications. Pocket filters are available in many different sizes, shapes and frame materials such as plastic or metal. The filter medium consists of fine synthetic fibre media sewn into wedge-shaped filter pockets. The filter class depends on the fineness of the filter medium. The number and length of the pockets can be customised to the requirements of the application. Optionally, pocket filters can be made antistatic and odour-inhibiting. The filter has several individual pockets and has a particularly large filter surface compared to other filter types. Pocket filters are the most common air filters in systems for industrial and commercial applications to improve indoor air quality and comfort.  

Structure: 
  • Standardised filter frames made of plastic and metal 
  • Filter media made of needle felt, polyester or glass fibre media suitable for coarse or fine filtration 
  • Antistatic, odour-inhibiting equipment possible 
  • Pockets for collecting large quantities of dust  

Advantages: 
  • Large dust volume absorption as filter cells or filter cassettes 
  • Low acquisition costs 
  • Easy filter replacement  

Areas of application: Ventilation systems, large construction and agricultural machinery with driver's cabs, paint shops 
Dust classes: ISO Coarse 55% bis ISO Coarse 80% (EN 779:2012: M5 – F9)
