Panel Finedust / HEPA Filter Type GP Overview The GP filter is designed and tested to extract the smallest particles out of the air. The GP series contains a fibreglass media pack in four (4) different heights (47mm, 56mm, 70mm, and 93mm) and in different kinds of extruded aluminium frames. The filter media is pleated in ‘Minipleat shape’ with a new application technology of ‘Hot Melt Spacers’ to achieve the lowest pressure drop results. FEATURES • HEPA efficiencies of 95% up to 99.99995% (@ 0.3 μm) • Finedust efficiencies of 60% up to 98% ASHRAE • Lowest initial pressure drop Fine Dust Filter • Rigid frames Finedust - HEPA / ULPA • High quality micro-fibreglass paper 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

APPLICABLE STANDARDS: Testing The prefilters are tested in accordance with European Standard EN 779 (Particulate air filters for general ventilation). This standard is based on ASHRAE 52.1 (Gravimetric and Dust-Spot Procedures for Testing Air Cleaning Devices Used in General Ventilation for Removing Particulate Matter, 1992). XY - Scan Testing Device Filt Air 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...
