Introducing the Model 7000: a groundbreaking blower door fan. Weighing in at just 23 lbs- over 30% lighter than its predecessors- the Model 7000 sets a new benchmark for portability and efficiency.

The innovation doesn’t stop there. The Model 7000 delivers even greater power than Retrotec’s trusted Model 5000. Pair it with our cutting-edge DM32X gauge, and you’ve got the blower door reinvented, delivering a completely revolutionized testing experience.
Features
Remarkably lightweight. An astonishing 30+% lighter than other fans on the market.
Extremely powerful. Reach higher CFM @ 50Pa than the Model 5000 Fan (in many scenarios, even more than the 6000 fan).
Built in accelerometer acts as an “auto tip” sensor. Fan will shut off if tipping is detected.
Electronic Speed Control (ESC) takes the 48c DC Supply & conveys it to 3-phase to the motor for precision speed control and adjustment.
New safety feature enables auto braking of the DC motor in the case of fan failure.
Fans never go in wrong direction during multi fan test.
