Abstract
A filtration apparatus for use in a system containing a gas or liquid to be decontaminated. The apparatus has at least one housing for a filter that removes contaminants from a gas or liquid which include biologics and chemicals. The housing contains an inlet portion and an outlet portion in association with valves for closing or regulating the flow of gas or liquid to be decontaminated by the filter. A differential pressure gauge is optionally provided to monitor the pressure in the housing and to indicate when the filter should be replaced. One or more housings can be used for the apparatus. The apparatus is useful for securing water systems, gas delivery systems, and vacuum systems.
Claims14
A biological filtration apparatus which decontaminates biologics or chemicals for use in a system containing a gas or liquid to be decontaminated which comprises:
- at least one housing having an inner chamber;
- an inlet and an outlet;
- at least one filter means in said at least one chamber for decontaminating the gas or liquid;
- an outlet portion for said apparatus for discharge of a decontaminated gas or liquid from said filter means and chamber associated with said at least one housing after decontamination;
- an inlet portion of said apparatus associated with an inlet of said at least one housing for receiving said gas or liquid to be passed through said chamber and filter means;
- first valve means associated with the inlet portion of said at least one housing to selectively close off the inlet to said at least one housing and to control the flow of said gas or liquid;
- second valve means associated with the outlet portion of said at least one housing to selectively close off the outlet of said at least one housing and to control the flow of said gas or liquid whereby any biologics or chemicals are decontaminated.
A filtration apparatus for use in a system containing a gas or liquid having a biological or chemical to be decontaminated which comprises;
- a pair of parallel cylindrical housings having an inner chamber for housing at least one filter means;
- said apparatus having an outlet portion for discharge of a gas or liquid from said chambers, and an inlet portion for receiving a gas or liquid to be decontaminated;
- substantially identical inlet conduits communicating with the inlet of said apparatus;
- substantially identical outlet conduits communicating with the outlets of each of said housings and the outlet of said apparatus;
- valve means in each of said inlet conduits for selectively closing off said inlet conduit to preclude gas or liquid inflow to the respective chamber;
- valve means in each of said outlet conduits for selectively closing of said outlet to preclude gas or liquid inflow so that the gas or liquid will be processed through the open chamber, and
- differential pressure gauge associated with the conduits of each housing, whereby any biologics or chemicals are decontaminated.
