Abstract
An access door that includes a scanning mechanism for a containment system, a containment system having the same, and a method for leak testing a filter installed in the containment system are described herein. In one embodiment, a containment system is disclosed that includes a housing having a downstream test section access port selectively sealed by a downstream test section access door. A displacement assembly is coupled to the downstream test section access door and is operable to move a plurality of probes disposed in the housing relative to the test section access door.
Claims19
A containment system comprising:
- a housing configured to hold a filter in a position that separates an upstream section from a downstream test section, the housing having a filter access port for replacing a filter disposed in the housing, the housing having a downstream test section access port formed in the housing communicating with the downstream test section;
- a filter access door configured to selectively seal the filter access port;
- a downstream test section access door configured to selectively seal the downstream test section access port;
- a plurality of probes coupled to the downstream test section access door;
- and
- a displacement assembly coupled to the downstream test section access door, the displacement assembly operable to move the probes relative to the test section access door.
A downstream test section access door comprising:
- a door assembly configured to selectively seal a containment system access port;
- a plurality of probes configured to obtain air samples;
- and
- a displacement assembly coupled to the test section access door, the displacement assembly operable to move the probes relative to the test section access door.
A method for testing a filter disposed in a containment system, comprising:
- flowing air into the containment system and through a filter disposed in the containment system;
- and
- scanning the filter with a plurality of probes mounted to a door of the containment housing.
A containment system comprising:
- a housing configured to hold a filter in a position that separates an upstream section from a downstream test section, the housing having a filter access port for replacing a filter disposed in the housing, the housing having a downstream test section access port formed in the housing communicating with the downstream test section;
- a downstream test section access door configured to selectively seal the downstream test section access port;
- a displacement assembly disposed in the housing;
- a plurality of probes disposed in the downstream test section and non-intrusively displaceable by the displacement assembly;
- a filter access door configured to selectively seal the filter access port;
- a plurality of sample ports formed through the downstream test section access door, the sample ports coupled to the probes by tubing.
