Filter Fans: What is the difference between the FF & FPF?

The re-engineered FF series of filter fans offers an innovative easy-to-mount solution that requires no tools thanks to a simple click-fit design. Due to its enhanced construction, the FF considerably reduces the risk of water infiltration and increases operational safety. We explain the key differences between the FF series and the original FPF series of filter fans below. FF Filter Fans Diagram no title Key Changes between the Old Style FPF and the New Style FF Range of Filter Fans Click-fit rapid installation with mounting clips Innovative new mounting clips have been added to the FF series to allow for fast, tool-free installation. No screws are needed as the filter fan unit uses a cage clamp system and is simply pressed into the enclosure cut out. It is designed to work with multiple panel thicknesses from 1mm to 8mm. Although the FPF series also have mounting clips, they are more limited in terms of the thickness of the panel to which they can be applied. Easy slide opening A key difference between the FF and FPF design is the sliding front cover. To replace filter media, the cover of the FF can be easily slid upwards and removed by hand with no need for tools. Whereas, a screwdriver is required to take off the FPF cover. Whilst this is a small change, it will save maintenance time and reduce the risk of damage to the cover. Improved water resistance Both FF and FPF series benefit from Fandis design features, such as, slanting louvres on the filter cover to facilitate water runoff. However, the FF also has angled grooves in the seal between the base and cover to improve moisture resistance up to IP55. This can be increased to IP56 with use of a stainless steel cover. The FF series offers a Type 3R certified version suitable for outdoor installation. Type 3R, is a certification which identifies specific products that are proven to be effective in difficult conditions where there is a requirement for elevated IP protection. Type 3R FF filter fans have additional metal grids placed internally to the filter providing excellent protection from adverse weather conditions and from the intrusion of solid bodies. Hidden seal The FF benefits from a dedicated perimeter seat that houses the seal between the filter unit and the enclosure. This has been added to improve ingress protection by allowing the filter to sit flush to the panel without letting dust settle on the seal. Materials The FF range is manufactured using glass fibre reinforced plastics in addition to usual PC / ABS blend plastics. This preserves the life of the product when exposed to atmospheric agents and weather conditions that promote deterioration. EMC versions are available in both the FF and the FPF ranges. The EMC version filter fans provide protection against electromagnetic radiation due to the outer metal shielding which creates a barrier of protection as it meets the electromagnetic walls of the enclosure.
