Pfannenberg 4th Generation High Air Flow Filter Fans

The filter fan has a new-to-the-market pleated fabric filter and louvre design that gives a high airflow at IP55. Its unique, patented water and dust pre-separation in the lamellas ensures that the majority of water and dust never reach the filter mat, extending its lifetime and therefore reducing the maintenance requirements. The "Click and Fit" design eliminates the need for fixings, providing hardware-free installation and filter mat changing, giving a unique user-friendly product. The new filterfan generation comprises IP54 variants, which filter to the improved G3 specification, and IP55 versions capable of G4 level filtration, with EMC versions of both. It features a new, patented 4-corner locking / fastening system; the terminal is of a cage clamp design and its position is changeable through 90° step turns to accommodate differing wiring directions. The units in the range are completely reversible to either introduce or extract air from the enclosure. Provision is made for mounting a thermostat on the rear face of all exhaust filters to reduce energy consumption. IP55 variants are also UV stable and suitable for use in outdoor applications without any extra protection. The cutouts are compatible with the previous generation and with those used by major competitors.
