The disclosure relates to an apparatus for removing a sterilant from a sterilant containing atmosphere of a room comprising an enclosure (10) having an inlet (13) to receive sterilant containing air from the room following sterilization of the room, outlet nozzles (17) to return air from which sterilant has been removed to atmosphere and a catalyst (15) within the enclosure for removing sterilant from the air. A fan (14) draws sterilant containing air from the inlet through the catalyst and thence to atmosphere. An additional fan (18) is provided to circulate air containing sterilant from the room during a room sterilization process through that part of the enclosure which is downstream of the catalyst to ensure sterility of that part of the enclosure for the sterilant removal phase.
An apparatus for removing a sterilant from a sterilant containing atmosphere of a room comprising an enclosure (10) having an inlet (13) to receive sterilant containing air from the room following sterilization of the room, an outlet (17) to return air from which sterilant has been removed to atmosphere, a catalyst (15) within the enclosure for removing sterilant from the air, and means (14) for drawing sterilant containing air from the inlet through the catalyst and thence to atmosphere, characterised in that means (1 8) are provided to circulate air containing sterilant from the room during a room sterilization process through that part (12) of the enclosure which is downstream of the catalyst to ensure sterility of that part of the enclosure for the sterilant removal phase.
An apparatus as claimed in any of the proceeding claims, characterised in that the catalyst (15) is a carbon filter.
An apparatus as claimed in any of the proceeding claims, characterised in that the outlet comprises a nozzle or nozzles (17) for directing the stream of air from which sterilant has been removed into the atmosphere around the enclosure to create turbulence in the air.
An apparatus as claimed in any of the proceeding claims, characterised in that the supplemental means (18) to draw sterilant through the part (12) of the enclosure downstream of the catalyst during the room sterilization process comprises further fan means of relatively low throughpull compared with the first mentioned fan means having a further inlet disposed in said enclosure on said downstream side of the catalyst-to draw air containing sterilant from the atmosphere into the enclosure during the room sterilization process and to circulate air through the downstream side of the enclosure to sterilize that part of the enclosure, the air containing sterilant being released from the enclosure by said outlet from the enclosure.
An apparatus as claimed in any of the proceeding claims mounted on wheels to be readily mobile.
