Terminal-Housing with Inserted HEPA Filter Type HT Overview The HT Terminal High Efficiency Filter is designed and tested to extract the smallest particles out of the air. Each HT Housing Filter contains a ‘Minipleat-Filter’ available in different heights with a new application technology of ‘Hot Melt Spacers’ to achieve the lowest pressure drop results. The filter can be changed from the inside of the room, an option that makes maintenance faster, easier, and therefore, cost-efficient. FEATURES • Easy filter installation (change) from inside the clean room • Efficiencies of 95% up to 99.9995% (@ 0.3 μm) • High quality micro fibreglass media • Adjustable airflow by means of a damper • Two different damper designs Finedust - HEPA / ULPA • Lowest initial pressure drop Fine Dust Filter Final Filter for Fan Filter Units Final Filter for Clean Rooms Final Filter for Channel Installation Highly Active Filter Surface - Low Pressure Drop Final Filter for Grid Systems

FEATURES: • Anodized rigid aluminium frame • High quality standard due to Quality Assurance System • Tested by laser particle counting system • High economic through high final pressure drop • For use in clean rooms up to class 1 Design The filter frame is made from an anodized extruded aluminium profile with two-angled corners, producing a rigid, straight frame. The zinc-coated hood with attached collar is tie-glued onto the top of the housing. On the damper (version A), the aerosol/pressure drop checking-inlet is situated in a special middle bridge and is adjustable from downstream. The...

APPLICABLE STANDARDS: Testing Each filter is tested and packed in accordance with American Standard IEST-RP-CC001.3 (HEPA and ULPA Filters), in accordance with the European standard EN 1822-1 4&5 (testing filter elements, HEPA and ULPA efficiency, and scan method), or customer requested testing. XY - Scan Testing Device Filt Air’s XY-scan testing device is able to perform automated filter leak testing of high efficiency air filters using automatic particle counters and a motorized scan table. While the particle counter probe passes over the filter face, the computer compares the counted...

Version A of the damper system is a combination of an in-room adjustable damper with an aerosol inlet for efficient checking of the installed filter. This feature allows for easy adjustment of the airflow (filter velocity) during checking with a velocity meter from the clean room side. In addition, for DOP efficiency testing (of installed filters), an aerosol entry is provided to allow for easy channelling of the test aerosol to the upstream side of the filter media. Both are covered with a sealed screw to prevent any leaks. Version B of the damper system offers a functional possibility for...
