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.

Quality

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.

HS-Activated Carbons

Activated carbon for gas- and odor filtration. Availiable as bag- or bulk goods.

HS-Luftfilterbau supplies Activated Carbone in shaped and pulverised format. The granule size of shape and corn coal ranges between 0.6 and 6.3 mm, according to it’s application, pulverised activated charcoal has a granule size of <0,075mm. This activated charcoal is manufactured from various raw materials, compost, coconutshells or sugar. This is achieved either by burning, or special treatment procedures to achieve a substantial enlargement in the “outer” and “inner” surface.

Through this process the finest porous surfaces and the finest capillary systems are created, which increases the absorbent surfaces up to 1700 m²/g. This in turn results in excellent filter efficiency and dust storage capacity and enables a long life span and high capacity of the active coal filters. Basic rules with the use of active carbon:

  • with increasing virtual contact with the active carbon or larger amounts of coal being used, the efficiency of the coal used is increased.
  • For the absorption of special pollutants impregnated active coal is used.
  • The air temperature of the flowing air shall not exceed 50ºC as from this temperature onwards some of the pollutants will be released by the coal. Any materials to be filtered have to absorbable. (Refer to table).
  • Active coal is very sensitive towards dust, and therefore it is recommended to use high quality and efficient dust filters as a primary filters for non-gaseous pollutions.
  • The basic rule: any gas molecules, which have more than three non-hydrogen atoms, are easy to absorb.

Please contact us for more, specific informations about the materials you need to adsorb.
