Description
The Retrotec DU402 reducer is designed to facilitate duct tightness testing using the Retrotec DucTester commercial duct system. This part allows a 10″ diameter duct to be adapted to a 2½″ connection, facilitating measurement in installations where the standard adapter does not fit.
Thanks to its robust construction, this accessory helps to keep the air flow controlled and accurate during testing, ensuring reliable results and reducing assembly speeds on site. Ideal for HVAC technicians, energy auditing and ventilation leakage testing.
