GTS Terminal Filters

Each high efficiency filter, pleated in ’Minipleat shape,’ is available in different heights and is cast into the frame and middle bridge

  • GTS Terminal Filters

    The GTS terminal high efficiency filter is designed and tested to extract the smallest particles out of the air. Each GTS terminal filter contains a ‘Minipleat-Mediapack’ available in different heights with a new application technology of ‘Hot Melt Spacers’ to achieve the lowest pressure drop results.

  • Design:

    The housing is made from anodized extruded aluminium profile with two galvanized angles in each corner to create a rigid, straight frame. The alu-zinc hood, with an attached collar, is glued on top of the filter. The damper and the aerosol / pressure drop checking inlet is placed in a ­special ­middle bridge and is adjustable from downstream. The fibreglass media, pleated in ‘Minipleat shape,’ is available in different heights of 47 and 56. The filter cake is cast into the frame and middle bridge. This design produces high surface filtration and ensures the minimal ­pressure drop of the GTS model.

  • Testing:

    Each HEPA filter is tested and packed in ­accordance with American standard IEST-RP-CC-001.3 (HEPA and ULPA Filters) or in accordance with the European standard BS EN 1882-1, 4&5 (testing filter elements HEPA and ULPA efficiency and scan method) or other customer requested Testing. The prefilters are tested in accordance with European standard BS EN 779 (Particulate air filters for general ventilation). This standard is based on Ashrae 52.76 (Gravimetric and ­Dust-Spot Procedures for Testing Air Cleaning Devices Used in General Ventilation for Removing Particulate Matter 1992).

  • XY – Scan Testing Device:

    The 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 particles with the given leak tolerance setting. In addition, it calculates the overall ­efficiency for each checked filter and measures the pressure drop @ nominal airflow.

  • Dampers:

    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.
