Retrotec US3212 Blower Door with Model 3000 Double Fan
This is a high output air leakage test system, featuring two of the Model 3000 Calibrated Fans, a tight fitting double-hole cloth door panel, and a DM32 gauge. The upgraded 2 horsepower 3350 speed control drives combined with the duo of 8 blade fans puts out over 17000 CFM, making the system ideal for testing large residential homes and some commercial buildings with a single fan.
Included is a larger size, easy-to-install aluminum frame door panel which adjusts to accommodate those enclosures that have larger than standard doorways. The door panel comes in a rugged carrying case complete with a custom designed cloth that can hold two fans in one aluminum frame, industrial strength velcro straps to hold the fans securely and numbered aluminum frame pieces that make set up quick and easy. Extra crossbars help keep the frame secure in the doorway even under high test pressures.
With the fans installed in the door panel, the 3210 Series Blower Door perform fully automatic testing using the gauge, a laptop and our FanTestic software. Alternatively, simply key the desired test pressure into the gauge and read “Air Changes” or “leakage per unit area” in real time directly from the touchscreen gauge; a unique and highly sought after Retrotec feature. The gauge also offers an onboard "Set-and-Forget" control of building pressure. All you need to do is choose your desired pressure, and then let the gauge do the rest. As you seal the leaks in your enclosure and the leakage rate decreases, the gauge automatically and instantly adjusts the speed on the fans to keep the enclosure at the correct pressure.
Software provided with the DM32 touchscreen gauge provides automatic data logging, and remote gauge control from a laptop. With our new 5 year recommended calibration interval on the DM32, you will have the peace of mind knowing that yearly calibrations are a thing of the past.
Calibrated range configurations allow one fan to test a wide range of enclosures, from super leaky to super tight. This high output fan includes 11 flow ranges to provide accurate results over the widest range of enclosure volumes. All Retrotec fans are made with extremely durable space-age hard plastic foam, which makes them both lightweight and tough. They are also easily reversible: to switch from pressurizing to depressurizing your enclosure, simply flip the fan around in its panel.
![Intuitive-operation]()
Intuitive operation
Match the colored tubes to the ports even when pressurizing where you normally need to run an extra tube but not with Retrotec where the gauge figures it all out. You’re always hooked up correctly, nothing to remember; you cannot make a mistake.
