Filter fan unit RETURN AIR

The innovative solution for pure space manufacturing with build-laterally caused insufficient return air zones the problem definition: Ever more frequently plant farmer before problems with spatial delimitations with new installations are placed. These structural defaults open new chances for innovative product solutions. The solution: On basis of its experience of many years in particle contamination control M+W Zander Products a singular Portfolio at standard and High Tech FFUs offers for the most diverse requirements and Designs of today's pure space manufacturing. Thus the filters fan unit RETURN AIR was developed by M+W Zander Products particularly for installation situations, with which due to the build-lateral conditions no sufficient return air zones for the circulating air for the order. The function mode: Air is sucked in within the upper range and prepurified - depending upon execution - over a prescreener.Within the lower range air is cleaned over a suspended matter filter and brought vertically into the pure area. The categories of purity 5,0 to 8,0 can be obtained by production with low turbulences of a displacement current according to DIN EN ISO 14644-1 and/or M3.5 (1) to M6.5 (100.000) to US Fed. standard 209E. Over integrated return airducts arrived up to 50 per cent of blown out air again in the plenum and by the fan one sucks in there. The return airducts in the FFU are hoehenverstellbar, in order to integrate superstructures (straight AMC filters or fine dust filters). Through particularly developed air deflector panels at the finalconstant filter a short-circuit of air in the pure area is avoided. The advantages: These units for the equipment of individual jobs or also complete pure area are suitable. By these product properties still further advantages are obvious: The saving of double bottom height saves cash money.Beyond that the pure area with narrower return air pits can be realized. Likewise only relatively smaller circulating air radiators are necessary. By the reduction of the circulating air quantities in the return air pits additionally operating cost (TCO) is saved.
