Abstract
The invention relates to an air-guiding component (1) for a pipe system, in particular for a pipe system for gaseous media preferably used in an aspirating fire detection and/or air-monitoring system. The air-guiding component (1) comprises a housing (7) having a gas inlet (12a) and a gas outlet (12b), wherein the gas inlet (12a) and the gas outlet (12b) are fluidically connected or connectable to the pipe system in order to form a flow path from the gas inlet (12a) to the gas outlet (12b) in the interior of the housing. A connection region with a port (6) is also provided for fluidically connecting, as needed or optionally, the housing interior to a maintenance/cleaning device.
Claims7
A filtering air guide for an intake pipe system for gaseous media in an aspirating fire-detection or air-monitoring system (30), the air guide including a housing (7) having an interior and comprising:
- (a) a main housing (13) forming a component part of the housing (7) and having an opening (8), a gas inlet (12a) and a gas outlet (12b) and configured to receive a filter (5) interposed in a gas flow path between the gas inlet (12a) and the gas outlet (12b);
- and
- (b) a first component (10) forming a replaceable housing cover (14) that is an adapter part detachably connectable to the main housing (13) and closing the opening of the main housing (13) when the first component is detachably connected to the main housing, the first component (10) having
- (i) a fitting (6) with an opening into the housing interior through a wall region (11) of the housing cover (14), the fitting being connectable to a maintenance/cleaning device (22), and
- (ii) at least one shutoff element (16) projecting from the first component and positioned to register with the gas inlet (12a) or the gas outlet (12b) and reduce the effective cross section of the gas flow path when the first component is detachably connected to the main housing.
A kit for cleaning or maintaining a filtering air guide for an intake pipe system for gaseous media in an aspirating fire-detection or air-monitoring system (30), the air guide including a housing (7) having an interior and the kit comprising:
- (a) a maintenance/cleaning device (22) comprising a partial vacuum source or overpressure source,
- (b) a main housing (13) forming a component part of the housing (7) and having an opening (8), a gas inlet (12a) and a gas outlet (12b) and configured to receive a filter (5) interposed in a gas flow path between the gas inlet (12a) and the gas outlet (12b);
- and
- (c) a first component (10) forming a replaceable housing cover (14) that is an adapter part detachably connectable to the main housing (13) and closing the opening of the main housing (13) when the first component is detachably connected to the main housing, the first component (10) having
- (i) a fitting (6) with an opening into the housing interior through a wall region (11) of the housing cover (14), the fitting being connectable to the maintenance/cleaning device (22), and
- (ii) at least one shutoff element (16) positioned to register with the gas inlet (12a) or the gas outlet (12b) and reduce the effective cross section of the gas flow path when the first component is detachably connected to the main housing.
