Remote aerosol injection systems and methods for use
View Patent ↗Systems and methods are provided for testing filters. In an exemplary embodiment, a method is provided for testing a filter within a duct system that includes mounting a port to a wall of a duct of the system, positioning a section of tubing within the duct from the port until an outlet end of the tubing is disposed adjacent a filter, connecting a source of test media to the port; delivering test media from the source through the port and tubing into the duct to the filter, and scanning the filter for test media.
1. A method for installing a testing system for delivering test media into a duct system of a facility to test a filter of the duct system, comprising:
mounting an injection port to a wall or a ceiling of an accessible location within the facility;
coupling a first end of a section of tubing to the injection port;
mounting a delivery port to a wall of a duct branch delivering air to the filter; and
coupling a second end of the section of the tubing to the delivery port, thereby creating a path for test media from the accessible location to the filter via the duct branch without exposing other sections of the duct system to the test media.
2. The method of claim 1 , wherein the injection port is mounted to a ceiling of the facility.
3. The method of claim 1 , wherein mounting the injection port comprises:
cutting an opening in a ceiling of the facility;
inserting a fitting of the injection port through the opening until a plate of the injection port contacts the ceiling; and
securing the plate to the ceiling.
4. The method of claim 3 , further comprising coupling an elbow to the fitting above the ceiling, and wherein coupling a first end of a section of tubing to the injection port comprises coupling the first end of the section of tubing to the elbow.
5. The method of claim 1 , further comprising inserting a plug into the injection port.
6. The method of claim 1 , wherein the filter is located within a cleanroom and wherein the injection port is mounted in a ceiling outside the cleanroom.
7. The method of claim 6 , wherein the injection port is mounted in a ceiling of an anteroom adjacent the cleanroom.
8. The method of claim 1 , wherein the injection port is a first injection port, the delivery port is a first delivery port, and the section of tubing is a first section of tubing, the method further comprising:
mounting a second injection port to a wall or a ceiling of a second accessible location within the facility;
coupling a first end of a second section of tubing to the second injection port;
mounting a second delivery port to a wall of a second duct branch delivering air to a second filter; and
coupling a second end of the second section of tubing to the second delivery port, thereby creating a path for test media from the second accessible location to the second filter via the second duct branch without exposing other sections of the duct system to the test media.
9. The method of claim 1 , wherein mounting the delivery port comprises directing one or more fasteners through a plate of the delivery port into the wall of the duct branch, and wherein the second end of the section of the tubing is coupled to a fitting extending from the plate.
10. The method of claim 9 , further comprising removing external insulation from the first branch to expose the wall of the duct branch before mounting the delivery port.
11. The method of claim 1 , wherein the delivery port is mounted to the wall of the duct branch in an attic space external to the filter.
12. A method for installing a testing system for delivering test media into a duct system of a facility to test filters of a duct system of a facility including a plurality of branches communicating with respective filters, comprising:
mounting a plurality of injection ports to a wall or ceiling of an accessible location within the facility;
coupling a first end of respective sections of flexible tubing to each injection port;
mounting a delivery port to a wall of a branch of the duct system delivering air to each filter; and
coupling a second end of the respective sections of the tubing to respective delivery ports, thereby creating separate paths for test media from respective injection ports at the accessible location to respective filters without exposing other sections of the duct system to the test media other than the branches corresponding to the respective filters.
13. The method of claim 12 , wherein the filters are located within a cleanroom and wherein the injection ports are mounted in a ceiling outside the cleanroom.
14. The method of claim 13 , wherein the injection ports are mounted in a ceiling of an anteroom adjacent the cleanroom.
15. The method of claim 13 , wherein each delivery port is mounted to a branch of the duct system in an attic space of the facility outside the cleanroom.
16. The method of claim 12 , further comprising labeling each of the injection ports to identify the filter they service, thereby facilitating subsequent testing.
17. A kit for installing a testing system for delivering aerosol into a duct system of a facility to test a filter of a duct system of a facility, comprising:
a section of tubing formed from flexible plastic material;
an injection port including a mounting plate and a fitting extending from the mounting plate;
an elbow comprising a first end configured to be coupled to the fitting and a second end including one or more elbow connectors for connecting the elbow to a first end of the section of tubing;
a delivery port including a plate configured to be mounted to a wall of a duct branch and a fitting; and
a nipple comprising a first end configured to be coupled to the fitting of the delivery port and a second end including one or more nipple connectors for connecting the nipple to a second end of the section of tubing to create a path for test media from the injection port to the duct branch without exposing other sections of the duct system to the test media.
18. The kit of claim 17 , wherein the first end of the elbow and the fitting include mating threaded connectors.
19. The kit of claim 17 , wherein the first end of the nipple and the fitting of the delivery port fitting include mating threaded connectors.
20. The kit of claim 17 , further comprising a plug for closing an inlet in the injection port mounting plate.
21. The kit of claim 17 , wherein the injection port is a first injection port, the elbow is a first elbow, and the nipple is a first nipple, the kit further comprising:
a second injection port including a second mounting plate and a second fitting extending from the second mounting plate;
a second elbow comprising a first end configured to be coupled to the second fitting of the second injection port and a second end including one or more barb connectors for connecting to a first end of a second section of tubing;
a second delivery port including a second plate configured to be mounted to a wall of a second duct branch and a second fitting; and
a second nipple comprising a first end configured to be coupled to the second fitting of the second delivery port and a second end including one or more barb connectors for connecting to a second end of a second section of tubing to create a second path for test media from the second injection port to the second duct branch without exposing other sections of the duct system to the test media.
22. The kit of claim 17 , wherein the plate of the delivery port is flat and includes one or more holes to receiving fasteners to mount the plate to a wall of a duct branch.
23. The kit of claim 17 , wherein the fittings and the section of tubing have a diameter between about a half inch to one and a half inches.
