Includes all of the parts listed above for a typical duct testing system, except instead of a Flex Duct, the
Blower Door systems include an Aluminum Frame and Cloth Door Panel to tightly fit the Model 300 fan
into a doorway. Also included is a hard-sided case for the Aluminum Frame. The gauge can be placed
securely into the included gauge holder that holds it upright on the Aluminum Frame for easy access
during a Blower Door test.
To expand your DucTester into a Blower Door system for testing tight enclosures, you only need to add a
Low-Flow Cloth Door Panel with Aluminum Frame.
