Energy Efficient Design

The effective utilization of resources and the sustainable use of our environment are a requirement of our time. HS-Luftfilterbau GmbH stirves to optimzie it's ISO 14001 certified production by the useage of innovative materials and to increase the energy efficiency of our products. Most of our prodcuts haven proven in the field that high filtration efficiency does not exclude a reduction of the operational costs.


HS Luftfilterbau supplies uncompromising quality. This is what our customers expect from us. Therefore, HS Luftfilterbau GmbH implemented a highly effective quality and environmental management system. Continuous improvement processes are part of our company culture and ensure that all processes lead to satisfaction of the concerning parties. Our core ideals are founded on our ISO 9001 & ISO 14001 and KTA 1401 cerzified quality assurance system.

Cleanroom / Pharma / Medical

The latest production processes e.g. in the microelectronics and pharmaceutical industries require highest degrees of purity of the environment. HS-Luftfilterbau GmbH operates ultramodern production and test facilities for HEPA, ULPA and molecular filters to maintain clean and sterile enviroments. All our products are intensively tested according to internationals standards before leaving our factory.

HVAC / Ventilation

Clean air and healthy climate affect the well being of people. HS Luftfilterbau GmbH offers a comprehensive range of high quality air filters ensure optimum ventilation of working, residential, commercial and office spaces. A careful choice of materials guarantees energy and economic efficiency.

Modern technoliges offer new scopes for development. We offer ulta modern rapid prototyping solutions for pre-series runs, design verification and for the production of individual filters. Within shortest time we can model your filterselements and produce filtercases from plastics to fit in various filter media. As basic material for the cases we use PLA or ABS. This process is especially suiting the requirement for smaller dimensionised filters for process air handling or equipment technoligies. Feel free to use our competitive service for your development of series products.

No matter if you whish to create hexagonal filter or other special cartridges - we'll make it real.

Please contact our sales engineers for design and construction.

CFD Simulation

We develop your filtration soulutions with the aid of CDF analysis tools.

Sometimes things are very different as they seem. To avoid bad suprises we use several CFD tools to stay on track with filter developments. We offer our experience and simulation capacity to customers during cooperating development pojects with our customers.

Probesampler for Activated Carbon

safe sampler for monitoring sorbent media such as activated carbons

The HS-Probesampler is used for sampling activated carbon and other sorbent bulk beds. Regular laboratory monitoring is required for safety-relevant sorbtion applications such as the exhaust air filtration of radioactive or highly toxic gases. The HS-Probesampler made of stainless steel 1.4301 allows piercing even in tightly compacted pouring beds. It is therefore ideally suited for sampling powders, granulates and broken carbons.

mobile filter leak test equipment to test HEPA filters prior to their installation

For changing filters at safety relevant systems it is reccomended to perform a leak test with HEPA filters either after installation or just before mounting. Beside the usual particle measures with optical or CPC counters there's also the option to perform an oil fog test according to EN1822-4 to prove the integrity of the filter.

HS-Luftfilterbau GmbH offers a mobile and robust testsystem which gives reliable results. The HS-Fogtester consists of a rigid stainless corpuis and easy to handle oilfognenerators. The fog is generated from parafinoil and has a major particle concentration at 0,2 - 0,5 µm. The fog is pressed throgh the filter by compressed air. A special lightsource is provided with the tester to iluminate and visualize penetrating particles against a contrast surface in the back of the tester.

All leakages of HEPA filters in EN1822 classes H13 and H14 can be detected by this method quick and securely.

Filters of lower classes such as finedust and EPA filters can't be tested successfully due to their high penetration rate. This test should not be used for filters of classes of EN 1822 U15 and higher.

This testsystem requires in opposition to ususal particlecounters extremely low maintenance, is very robust and is not required to be calibrated.

HS-Leak Test Device

Test equipment used for approval of a bypass free filter installation.

The use of leakage testers provides additional safety when replacing filters. With help of the HS-Leakage Tester combined with a leakage monitoring grove correct and leak free fitting of filter media is guaranteed.



HS-Differential Pressure Transmitter

Transmitter for measuring and transmitting pressure differences

  • 65°

The HS-Differential Pressure Transmitter (HS-DPT) detects the differential, positive and negative pressure between the two pressure inputs and converts the measured value into a linear or square-root output signal of 0(4)...20 mA or 0...10 V. In this way, an
statement can be made about the degree of loading of filters and transmitted, for example, to a control system or control station. The converter is offered in three variants (see below).

Thanks to ATEX approval, use in dust-laden and potentially explosive environments is possible without any problems.


HS-Sealing Tool

Tool used for the secure welding of maintenance bags at Bag-In-Bag-Out / safe change.

Filters have to be replaced when the suggested end pressure has been reached. Depending on the application, due to toxic or hazardous substances contamination free filter replacement is essential. To ensure contamination free filter exchange we recommend the use of the bag-sealing tool in conjunction with a mobile, height adjustable HS-Service trolley.



Adapter for screw drillers, fitting the starscres of all cover plates of our safety filter units

Filterchanges of big filter units may require to losen and re-fit 400 - 600 starscrews. Doing this by hand whilst wearing full protection can be very longsome and exhausting. When using our HS-X-Screw dill adapter this work is done much more relaxed in a fraction of the usual time.


HS-Maintenance Bag

Maintenance bag for safe change (Bag-In-Bag-Out).

A must for a contamination-free filter replacement is this robust maintenance bag made from PE. We also offer o-rings for proper fixation in various sizes or special variants with arm sleeves.
