Retrotec has been manufacturing blower door and duct testing equipment for over 30 years.
Commercial duct testing equipment.
Duct testing must be performed by an independant third party state certified hers raters and involves pressuring the duct system to a specified level and verifying that the ducts leak at a rate no greater than 6 of the total airflow.
The fastest and most convenient duct air leakage tester in the industry kanomax has developed the most advanced duct air leakage tester dalt for commercial duct systems.
Who is a trained qualified and certified person.
Commercial duct pressurization testing during the construction process when the duct is accessible before the grilles and equipment is installed each intentional opening in the duct system is sealed air tight with plastic and tape.
We are certified for residential commercial duct testing in both the new construction and alteration categories.

Measure duct leakage in commercial systems up to 295 cfm at 8 inches water column in wc with the first truly lightweight 20 lb handheld commercial ductester.
A complete game changer.
While the technology has been around for many years it is still not yet commonplace so there is great opportunity for contractors who want to add this service to their capabilities.
It s designed to be simple to use accurate and extremely convenient.
The duct system is then placed under high pressure and the airflow through the fan is measured.
Mount your dm32 wifi gauge directly onto the shell for easy accessibility.
The methods of measurement is a depth gauge comb which is scraped along the duct surface and for example a measured depth of 0 078 inches indicates the need to remove the deposition risk.
With 1700 watts of power available any comparable commercial duct tester will weigh 120 lb or more.
