FLT - GFV FILTERS AND FANS
The “FLT ..7” series of filters and filters with “GFV ..7” fans permits the user to obtain IP54 level protection (an IP 55 level of protection can be obtained on some of them on request, by simply substituting the filtering cloth), and has been widened with new models, to satisfy the Increasing needs of our customers.

MOST IMPORTANT FEATURES
The plastic parts are in ABS UL 94-V0 (nylon charged with fibreglass), which guarantees self-extinguishing capabilities. The filtering cloths are in non-fabric material that has a high yield and progressive structure, in synthetic thermally bound and unbreakable fibres. They are resistant up to 100° C and up to 100% of relative humidity. They can store up to 650 g/m2 of dust. The loss of initial load is 25 Pa. The cloths can be cleaned by rinsing, treatment with a jet of water or beating. Quality is in accordance with DIN 24185 norms. The fans utilised in the kit are built according to CE, VDE and TUV norms. The rotation supports are exclusively ball bearings for high dependability and long life (Min. 50,000 hours at 25° C and 65% relative humidity). All of the materials can be recycled.

OTHER CHARACTERISTICS
115 V AC or 230 V AC feed voltages are available. Other power voltages in AC and DC are available on request. Standard suction air flow (from outside the electric panel towards the inside); on request, the opposite air flow (forced) can be installed for filtering groups with a fan. Standard RAL 7035 colour. Standard level of protection IP 54 (on request IP 55 protection or EMC protection is available).

ASSEMBLY
Assembly of the filters takes place flush with the electric panel to avoid harmful external displacement (maximum protrusion from the panel 8 mm). Assembly on the panel with 1.2 ÷ 2.2 mm thickness is performed with a snap on clip, with no need for screws. The field of tolerance of the boring with respect to the nominal dimensions is 1.5 mm.
