Main demands of the clean room technology and especially in pharma­ceutical applications are the air-conditioning and also accordingly the air quality. Air distribution is generally made through the HEPA filter installed to its housing. Therefore, selection and assembling the HEPA filter to its housing without leakage is very important.

HEPA Filter Housing consists of three main parts, which are the box, filter and the diffuser. Box has a duct connection port for air inlet at the top or at the sides. Filters can be chosen according to the room Class from El Oto U 17.

All HEPA Filter boxes with test groove system are tested for leakages. Test grooves that face the HEPA filter gasket achieves air tightness according to DIN 1946-4 and ISO 14644-3 Inside of the housing can be easily disinfected and will not be effected from disinfection chemicals.

To track filter working conditions, HEPA boxes have nozzles for differential manometer connections. Test aerosol inlet nozzle is standard for DOP/EMERY Test.

*Please check the fitting of diffuser, box and ceiling before order to provide tightness.
