Technical characteristics

The EVO-H-MRH recirculation modules are designed to clean the recirculation air in the operating room and other rooms with high hygienic requirements. Amount of air that is supplied to the air-conditioned clean room is increased but the use of the module allows to reduce the size of the AHU system in the operating room (including the air conditioning unit) and to save operating costs. The devices are installed in the operating room or in adjacent rooms which also need the purified air. The modules are compatible with the NSL laminar ceiling equipped with connections and additional air channel. The recirculation modules are produced in two sizes. There are two options for mounting the air supply connection: upwards and from the front. A radial fan with forward curved blades, double-sided suction, directly driven with an EC motor, is used to force the airflow. The silencer’s lever is made in a hygienic version, easily disassembled from the module’s housing. Compact filters F7 or F9 class (according to PN-EN 779) or equivalent according to PN-EN ISO-16890:2017 are used for air purification. There is a hygienic exhaust air grille of GWB-G5 type installed at the inlet to the filtration section.
