HT Group completes extension of products and services in the field of HEPA filter housings successfully

After the ceiling-integrated HEPA filters, make “HT_clean” and the partly bolted and welded filter housing following modular design principles were added to wide range of HT Group´s product range, the product group of filter systems has now been completed with the new fully welded filter system for high-safety laboratories completed the HEPA filter family.

The new filter housing is characterized by a corrosion-resistant, fully welded and gas-tight design and is used in supply and exhaust air systems to separate highly sensitive particles, such as microorganisms, for class 3 and 4 safety laboratories and meet the requirements of standards and guidelines for these areas.

The clamping device is operated from the outside and dimensioned in such a way that with maximum admissible loading of the filter elements and retreating sealing of the filter element due to e.g. aging, compliance with the tightness requirements according to DIN 25 496, Table 3, is ensured.

The new filter housing includes the following safety functions:

• Inspection of the integrity of the filter element seal from the outside
   
• In-situ leakage measurement of the HEPA filter element according to ISO 14644-3 with a fully automatic, movable scanner system
   
• Contamination-free filter element exchange on the basis of bag-in-bag-out technology.
   
• Monitoring of filter elements with pressure measuring devices, make “Magnehelic”, and measuring pipes, which are protected against the spread of contamination by inline-filters.
   
• Suitability and preparation for decontamination with disinfectants such as hydrogen peroxide.
   
• Double protection of connections of the housing secured against contamination spread to the outside, e.g. all particle measurement- and seal test connections are designed with manual ball valves and quick-release couplings.         

Immediately after the launch, HT Group was able to announce incoming orders for international high-safety laboratories in the Netherlands and Taiwan.

“The HT Group is constantly working on expanding its own range of products and services to demonstrate its leading international role for BSL-3/4 laboratories," said Thomas Fritsch, CEO of the HT Group.

He added that the new filter housing will be presented with a life act as part of the 5th  International Conference on Biosafety and Laboratory Technology from November 29th to November 30th 2021 in Berching.
