Conical Finedust Filter Type GRV Overview The GRV conical filter cartridges are especially designed to meet the high demands of gas turbine air filtration systems. The special filtration media provides maximum protection for the turbine. The outstanding durability and the high efficiency of the filter media decreases the risk of dust entering due to media failure and decreases the values due to high penetration. FEATURES: • For use in gas turbine air filtration systems with backpulse cleaning • For use with filter type GR0 as filter pair • High quality paper made of cellulose & synthetic components • Filter is pulse cleanable • Lowest initial pressure drop Finedust - HEPA / ULPA • Long lifetime through media with high tensile strength 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

Design The filter has zinc-coated steel end-caps on each end. The upper one has a glued plastic ring that holds the filter in position and the lower one has a glued cylindrical gasket with tight connection to the housing. AVAILABLE STANDARDS: • High quality standards due Quality Assurance System • ISO 9001:2008 The reinforced pleated filter media FA8267 is cast together with the expanded zinc-coated steel screens into the caps and sealed with polyurethane. The embossed pleating spacers at the top of each pleat and the hot-melt fixation on the inside ensure the uniform shape of the filter media...
