Knows air condition technology GmbH - optimized with low turbulences the circulating air covers type ULA.4

The ULA.4 belongs to the new generation of OI pure air covers. It is built to the finalconstant suspended matter filters H14 (alternative H13) as a whole in the intermediate cover of the OI and consists of an air discharge opening element, (einlagiges, according to the requirement doppellagiges or Differenzialflow polyester tissue), in accordance with DIN EN 1822, a Druckkorpus of anodized aluminum or high-grade steel inclusive muffler as well as of circulating air modules. The circulating air modules contain one in air direction seen circulating air-suck in (high-grade steel Microgewebe or polyester tissues), a F9-Filter, in accordance with. DIN EN 779, a muffler, fans with check valve as well as the supply air connection. Function mode: The room air is sucked in on the circulating air module, mixed with the supply air prepared by the air conditioner in the module and promoted to the Druckkorpus arranged over the filter cover. Pure air flows afterwards filtered into OI and forms the protected zone.The ideal pure air discharge opening with low turbulences of the ULA.4- cover has plexiglass over a homogeneous diverting surface without neutral zones and a circulating apron made of group security, down-pulled up to door fall height -, or. Advantages of the new ULA.4 mixture of the circulating air and the supply air in the circulating air module arranged before entrance into the Deckenkorpus complete homogenized diverting behavior sound pressure level in accordance with guidelines reaches no fire load flexible assembly (no fixed points) measuring connecting pieces for task and measurement of the test aerosol clearly and central variable frame system with highest accuracy to size integrable into clean-spacefair, surface-concise "barrier ton Wall" system
