Air-conditioning and ventilation filters
We are your filter professionals. We offer a wide range of filters for air-conditioning and ventilation systems in accordance with DIN/Norm EN779 or ISO 16890, such as:
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.
Z-line filters
These versatile pre-filters meet the highest safety standards. Whether designed as pre-filters for pocket filters, HEPA filters, heating, air-conditioning and ventilation systems, extractor hoods or control cabinets: ELSÄSSER mat filters are always the right choice!
Panel filters
Designed for use as primary or secondary filters in ventilation, heating, and air-conditioning systems, ELSÄSSER panel filters deliver high performance thanks to the use of high-quality, robust materials.
Filter mats
These versatile pre-filters meet the highest safety standards. Whether designed as pre-filters for pocket filters, HEPA filters, heating, air-conditioning and ventilation systems, extractor hoods or control cabinets: ELSÄSSER mat filters are always the right choice!
HEPA filters
These filters are perfect for use in the pharmaceutical and healthcare sectors. They meet the strictest quality requirements for filtration of pollen, viruses, smoke particles, and toxic dusts in hospitals, cleanroom applications, microelectronics, and the food industry. HEPA and ULPA filters are available in filter classes H1 to H14 and U15 to U17. With ELSÄSSER HEPA filters you can achieve the highest possible separation efficiency.
Metal filters
Our metal filters are used in a variety of ways to filter oil-laden exhaust air. For example, ELSÄSSER metal filters can be used as dust and oil filters in cooker hoods in the catering sector and in industry in general.
Filters for paint shops
These versatile pre-filters meet the highest safety standards. Whether designed as pre-filters for pocket filters, HEPA filters, heating, air-conditioning and ventilation systems, extractor hoods or control cabinets: ELSÄSSER mat filters are always the right choice!
Activated carbon filters
Our activated carbon filters ensure clean air in hospitals, laboratories, kitchens, and sewage treatment plants. They can also remove hydrocarbon compounds from combustion residues, deposits from tobacco smoke, and sulfur compounds (for example).
Antistatic or biostatic versions are also available. Our product range includes coarse filters, medium filters and fine dust filters.
Air-conditioning and ventilation filters at ELSÄSSER
Our extensive air-conditioning and ventilation filter range includes the filter classes specified in the old (yet still-often-mentioned) EN 779 standard: G2, G3, G4, M5, M6, F7, F8, F9, and those specified in the new ISO 16890 standard: coarse, ePM10, ePM2.5, ePM1, and EN 1822-1 for E10, as well as U17 for HEPA filters. All of these products are characterized by impressive levels of safety and quality as well as environmentally friendly materials and short installation times. Experience our excellent service and take advantage of our products’ outstanding price / performance ratio.
Various air-conditioning and ventilation filters containing activated carbon are available for adsorption to remove unwanted substances from the air. We are also your competent partner for customized solutions in this product area. 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.
