Use Your DucTester or Blower Door as a Powered Flow Hood
Add Retrotec’s PP105 DucTester Powered Flow Hood attachment to convert your duct tester into a precise airflow hood.
Measure exhaust, supply, or return register flows, and even total air handler flow—especially handy during HVAC system inspections or code compliance checks.
This extension enhances mobility and minimizes equipment overhead.
Test Exhaust and Supply Flows; Measure Total HVAC Air Handler Flow
Flow hood setups allow direct capture of airflow at registers—ideal for kitchens, bathrooms, or balanced systems like HRVs/ERVs.
Measuring total flow for HVAC systems ensures correct sizing and commissioning—and can be performed quickly using existing equipment with the powered hood.
Enclosure Zone Testing
Use blower-door systems to assess airflow integrity in tight, compartmentalized zones:
Pressurized stairwells
Enclosure zones like raised floors, control rooms, or areas of refuge
Test cleanness or leakage between zones to support building safety or code-level pressurization requirements.
Water Penetration Testing
Blower doors can simulate wind-driven rain to test water resistance of building envelopes.
By pressurizing a zone and observing moisture pathways (often with smoke or moisture meters), you identify leaks before finish stages—avoiding callbacks.
New Business Opportunities by Offering Expanded Testing Services
Adding these tests attracts work from:
HVAC installers seeking flow certification
Building departments requiring stairwell integrity or pressurization testing
Project teams needing air-tight envelope validation under wind or moisture load
Use your existing blower door or DucTester gear—minimizing overhead and maximizing profit.
Key Takeaways
