Retrotec 301 Passiv Haus and Ducts

Over two years of development work and 4 injection molds later, the Model 300 has emerged as a unique and versatile testing system.  First, it has increased air flow to test a wider range of tight houses.  More power but a lot less weight too and the ability to run for hours on batteries!  The same fan makes an ideal duct tester. But there is more.This Super tight design, allows the Model 300 to measure flows down to only 5/1000 of a CFM (2/1000 l/s) which is low enough to measure a light switch or the leakage of a single nail hole with optional low flow plates. Option it into a high flow US style DucTester that operates on 10 inch flex or the European style that connects using 4 inch flex.

Super accuracy has been accomplished by the super tight tolerances of totally injection molded flow measurement parts and a unique flow pressure pickup guide fins that allow for super low but stable flow measurement. Nothing has ever been built with so much flow measurement innovation.

The Aluminium Frame has quick connect injection molded corners that decrease set up time with our snap together, snap apart frame while reducing leakage by 75%.  Making this the perfect Passive House frame.
