Air filters significantly influence the energy requirements of your ventilation systems.

It's high time: use energy-saving filters to reduce your energy requirements, CO2 emissions and operating costs. The purchase costs of energy-saving filters usually pay for themselves within one to two months.
This helps to achieve your climate protection goals and also saves you considerable costs! Good, isn't it?

For a well-founded decision, our energy experts will be happy to provide you with the calculation bases.

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.

HS-Econergy

Our program for greater sustainability in air filters envisages the substitution of fossil fuels with sustainable raw materials in the long term. A difficult mission in a product field with high demands on materials. For example, a compact filter absorbs approx. 300 - 600g of fine dust, with a net weight of 7.5 kg. After use, the filter (then approx. 8kg mass) is usually incinerated. Fossil raw materials are lost in the process. A start has been made: Compact filter HS-Mikro Pak 4V Econergy consists of up to 60% completely renewable raw materials.

Welcome

HS-Luftfilterbau GmbH is your innovative supplier of a wide range of air filtration solutions for HVAC, supply / exhaust air treatment in Cleanrooms, Medical-, Pharmaceutical- and Processair applications.

Here you will find high-quality air filters for many applications.  

From the standard air filter through to highly specified customer-oriented system solution, we offer you beside the complete range of usual standard products also fully tailored products according to your needs. All filter solutions we offer are manufactured in our production plants in Kiel / Germany.

New production line for temperature resistant compact & HEPA filters05.2023

We are constantly investing in the expansion of our capacities and the improvement of our products and services. A key aspect of our new production line for compact and HEPA filters is not only the fact that we can assemble completely new types of filter media for extremely demanding filtration tasks. The new plant complex also gives us new options in the field of temperature-resistant filters.

From now on, we can produce compact filters (HS-Mikro Pak) as well as HEPA and ULPA filters cost-effectively with temperature resistance up to 120°C.

Thanks to our new ABS plastic filter frames, even the more temperature-stable variants are fully incinerable and can thus largely be put to an energetic use (i.e. waste incineration) after use without any problems, as these products can be made completely metal-free. ABS plastic frames can replace steel and stainless steel filter housings almost everywhere. This saves operating costs and facilitates disposal.

HS-Inferno: keeps Pandora's box tight!02.2022

Process risks are not unavoidable, especially in complex applications with chemically and/or radioactive substances. If Murphy's Law occurs, pressure must be released from the containment in a controlled manner in an emergency or, in the worst case, fires or even explosions occur. In these cases, there is an acute contamination risk for the environment. The release of toxic and/or radioactive aerosols must be avoided at all costs by controlled pressure release. For this case, a HS-Inferno filter system is a risk minimization solution.

HS-Inferno offers ideal properties to be prepared in case of an emergency. Specially sintered stainless steel filaments serve as filter media to provide a filtration efficiency performance in the range of >99.95% MPPS i.e. ISO 29462 35H resp. EN 1822 H13 even in case of explosive pressure surges and temperatures above 600°C. The welded stainless steel construction can be designed either as a replacement filter element for extreme processes or as disposeable single use duct-housing solution for emergency cases.

We perform thermal simulations to evaluate the individual designs to avoid uncontrolled deformation and leakage at high temperatures and pressures during operation or in case of emergency.

HS-Inferno can be fabricated in standard filter element sizes e.g. 610x610x292 mm , but also in other process specific designs. Our engineers will design the solution for your individual process requirements.

Our project "HS-Econergy" stands for energy- and resource-saving filter solutions06.2021

Our project "HS-Econergy" stands for energy-saving and resource-saving filter solutions.

We at HS-Luftfilterbau GmbH have been pursuing the approach of sustainable production since the end of the 1990s. Last but not least, we underline our attitude to this with our environmental management, which has been certified for more than twenty years. While we have optimized our processes more and more in the past with regard to environmental compatibility, we consider the time to be more than ripe enough to also take certain risks in product development.  We will offer the market and consumers products that not only increase the energy efficiency of your ventilation system, but also give you the choice to reduce the consumption of irreplaceable raw material resources and the associated CO2 release in the production of air filters.

Storage filters (in this sense "air filters" for short) are essential consumable components to ensure the functionality of air handling systems. They consist of a variety of more or less high-quality and elaborately manufactured materials. In addition to the filter media, which consist of synthetic nonwovens or meltblowns, glass fibers or synthetic membranes, other important components are frames, seals and special adhesives. Optimization of the sustainability of these products has so far largely failed to materialize due to the price sensitivity of large-scale users and consumers. Manufacturers' efforts are mainly focused on energy savings during operation and the lowest possible manufacturing costs. In both cases, it may be assumed that these aspects of sustainability are already very advanced.

However, if you look at the resource requirements of a compact filter, which is used, for example, in HVAC systems, supply and exhaust air systems or gas turbines, an imbalance immediately becomes painfully apparent when you look at the figures. Filters of this type weigh 6 - 8 kg in standard dimensions. During the period of use, these filters store approximately 250 - 600 g of atmospheric dust, particles and aerosols.  In other words, a 7.5 kg filter (592x592x292 mm) will be disposed of after its weight increases to 7.9 kg when the final pressure differential is reached, or in other words: for a maximum of half a kilo of stored fine dust, 7.5 kg of mass must also be disposed of. Recycling of the components is not possible or would be extremely difficult simply because of the filtrates.

Thus, the balance of utility effectiveness for these products is conceivably poor.

Due to their widespread use and therefore large quantities, as well as their comparatively poor cost-effectiveness, the optimization of compact filters is our first development goal, which will be followed by a series of sustainability optimizations across our entire production range in the coming years. Here, it depends on users and consumers, i.e. ultimately you, whether we can consistently follow this path. The costs of sustainable products will initially be higher than those of conventional products. In the long term, however, these changes are unavoidable if we want to leave a planet worth living on to future generations.  Under the given circumstances, there is not much time left to carry out the transformation of our consumer goods and consumer products.

Our project "Econergy" starts this summer with our compact filter HS-Mikro Pak 4V Econergy whose plastic components consist of more than 60% renewable raw materials. If we succeeded in replacing our total demand of plastics in this segment, we could save about 70 - 90 tons of polystyrene per year and thus reduce the consumption of fossil raw materials in this supply chain by more than 70%.

Sad fact on the side: the production of 1 kg of polystyrene requires about 10 kg of crude oil, 7.4 kg of natural gas and 0.14 kg of coal to extract it.

We would be pleased if you would support us in this mission. Your purchase decision allows us to consistently continue on this path.
