Fandis has created the FF series Virdis line, a new generation of fan filters dedicated to enclosures ventilation. A patented fixing system with clips makes these fan filters easy-to-mount without tools. The FF series fan filters are suitable for 1 to 8mm thick plates and the assembly is obtained just by pushing the fan filter on the enclosure. The upgraded construction with a particular base with micro beads reduces the risk of water infiltration and offers safety advantages. The FF series fan filters are available in 8, 12, 15 and 20 sizes with protection degree of IP54 or IP55.
