HEPA filter

HEPA filter

HEPA filter with MDF frame

This HEPA filter or absolute filter is used wherever it is necessary to ensure a defined air purity for the protection of people and/or manufacturing processes.

HEPA filters with MDF frame are usually installed in short intervals, such as annually disinfected ventilation systems, clean room systems and work areas that require clean air. The filter material is high efficiency microfiberglass paper. Thanks to the mini-pleat technology, a high filtration area is available, which slows down the airflow to support diffusion separation. The fused-in spacers provide high stability and uniform drive geometry.

All HEPA filters of filter class H13 and higher are tested individually by the manufacturer for freedom from leaks in accordance with EN1822 using a scan test or oil filament test.

In addition to the commonly used built-in sizes, our range also includes filters in individual sizes.

HEPA filter with aluminum frame

These HEPA filters achieve collection efficiencies of up to 99.99995 % and are used in cleanroom technology with the highest requirements. These high-performance filters are mainly used where a low-turbulence laminar flow is required. Typical areas of application are operating rooms in hospitals, the semiconductor, pharmaceutical or food industries.

A highly efficient micro-glass fiber paper is used as the filter medium. Due to the large surface area, which is generated by means of mini-pleat technology, the flow velocity is extremely reduced, which supports the diffusion separation of the sub-microparticles. Due to the pleat spacing by means of threads made of special hotmelt adhesives, a high stability is achieved and a very uniform pleat geometry is generated, thus enabling laminar flow.

All HEPA filters of filter class H13 and higher are individually tested by the manufacturers for freedom from leaks in accordance with EN1822 by means of a scan test. In addition to the commonly used installation sizes, our range also includes filters in individual sizes.

The following standard installation depths are available:

  • with PU foam seal: 69mm / 78mm / 90mm / 115mm / 150mm
  • with neoprene seal: 30mm / 78mm
  • with gel seal: 80mm / 90mm / 104mm / 128mm
  • Sword profile design: 86mm / 109mm / 134mm

High performance HEPA filter

High-performance HEPA filters are characterized by the range of application at face velocities up to 3m/s (4000m³/h at 610x610x292mm). They are used as final filters in ducted air systems or in air treatment plants.

A highly efficient micro-glass fiber paper is used as the filter media. The mini-pleat technology and design creates an extremely high filter surface area and extremely reduces the face velocity, which supports diffusion separation of the submicroparticles. Pleat spacing using filaments made of special hot melt adhesives creates high stability and very uniform pleat geometry. Up to 12 pleated pleat packets installed in a frame in a v-shape result in a very high filter area with a compact design.

All HEPA filters of filter class H13 and higher are individually tested by the manufacturer for freedom from leaks in accordance with EN1822 by means of a scan test.

We offer this type of filter with galvanized steel or plastic frames in the standard dimensions used on the market.

High temperature HEPA filter

These HEPA filters are specially designed for high temperatures. The filter material in this case is also highly efficient micro-glass fiber paper. However, the temperature resistance is ensured by a different production technology than for standard products. For panels produced with mini-pleat technology, high-temperature adhesives or aluminum plates are used as spacers instead of standard adhesives. In the case of high-temperature hot-melt adhesives, a maximum operating temperature of +120°C can be achieved, and in the case of filters with aluminum spacers, a maximum operating temperature is usually specified from +250 - 350 °C, but there are also products specified for +500 °C.

All HEPA filters of filter class H13 and higher are individually tested by the manufacturer for freedom from leaks in accordance with EN1822 by means of a scan test.

We offer this type of filter with galvanized steel or stainless steel frames in the standard dimensions used on the market.

HEPA filter

V-cell filter

V-cell filters are widely used in the chemical and pharmaceutical industries and for extraction at workstations and clean workbenches.

They feature a very compact design and are therefore well suited for use in confined conditions or in mobile systems.

High efficiency micro glass fiber paper is used as the filter media. As with the high-performance HEPA filter, the mini-pleat technology and design is used, which extremely reduces the inflow velocity due to the high filter surface and enables diffusion separation of the sub-microparticles. Likewise, the pleat spacing by means of filaments made of special hot melt adhesive produces high stability and very uniform pleat geometry. And the filter packs installed in a frame in a v-shape produce a high filter surface area with a compact design.
