Multi-Filter Containment Enclosure Leakage Detection Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containment enclosures require disassembly for testing filters, leading to inefficiencies and increased error likelihood due to the complexity of reassembling filters, making effective leakage detection of multiple filters within a multi-filter containment enclosure time-consuming and ineffective.
Innovation Solution
A containment enclosure with integrated ports that allow for leakage testing of filters without disassembly, using a testing probe and test air supply to sample and analyze air upstream and downstream of filters, enabling individual filter testing within the enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filters are tested by disassembly and reassembly, then leakage detection can be performed, but the process becomes time-consuming and error-prone
Solution Approach 1:
Test ports are pre-integrated into the filter housing during manufacturing, positioned at optimal locations for leakage detection. This preliminary setup eliminates the need for disassembly during testing, allowing direct connection of testing equipment to detect leaks while maintaining filter installation status.
Solution Approach 2:
Test ports serve as intermediary access points that enable leakage detection without requiring direct access to filter sealing surfaces. These ports provide a mediated pathway for introducing test gases and measuring leakage, bypassing the need for physical disassembly while maintaining testing capability.
2Reliability
If filters are disassembled for testing, then leakage can be detected, but the complexity of reassembly increases error likelihood
Solution Approach 1:
The test ports are pre-positioned and pre-configured during filter housing manufacturing, with threaded connections and sealing surfaces already prepared. This preliminary action ensures that testing equipment can be directly connected without complex disassembly or reassembly operations, maintaining operational simplicity while enabling reliable leakage detection.
3Measurement precision
If multiple filters are tested individually through disassembly, then each filter can be evaluated, but the process becomes inefficient
Solution Approach 1:
Each filter housing is equipped with dedicated test ports that are spatially segmented and positioned to provide independent access to each filter's leakage pathways. This segmentation allows multiple filters to be tested simultaneously or sequentially without interference, maintaining individual evaluation precision while dramatically improving overall testing productivity through parallel processing capability.

AI summary
Embodiments of the present invention relate to apparatuses and methods for leakage detection for installed filters of a multi-filter containment enclosure, without requiring disassembly of the multi-filter containment enclosure. The containment enclosure of the present invention comprises a filter housing. The filter housing comprises one or more filter compartments for housing at least a first filter and a second filter. The filter housing comprises at least one port which is operatively coupled downstream of the first filter and upstream of the second filter. Typically, the at least one port allows for leak testing of the first filter and the second filter without having to remove the first filter and the second filter from the containment enclosure.
