Cloth Panel Systems
Retrotec Model Q4E consists of a [DM-2]. Fan and a cloth door panel.
The Q4E system comes with a highly portable and lightweight cloth frame that is adaptable to a wide range of door sizes. However, this system implements the stronger, 2 hp 3300 Series Calibrated Fan, capable of up to 8100 CFM, making it applicable in tests of larger residential and mid-sized commercial structures.
Control this system directly via the DM-2 Series 2 Channel Digital Pressure Gauge, or Download the Software to connect the DM-2 to your laptop and run your test automatically.
All Retrotec fans are made with extremely durable space-age hard plastic foam, which makes them both lightweight and and tough. They are also easily reversible: to switch from pressurizing to depressurizing your enclosure, simply flip the fan around in its panel.
The DM-2A that comes with this system offers an onboard “Set-and-Forget” control of enclosure pressure and flow pressure. All you need to do is choose your desired pressure, and then let the DM-2A do the rest. As you seal the leaks in your enclosure and the leakage rate decreases, the system automatically and instantly readjusts to the correct pressure.
[DM-2] measures and controls pressure and air-flow automatically. Air change rate, ELA or air-flow per unit area results without a computer!
[3300] Fan has a variable frequency drive that runs on both 110 and 240 Volts. On 50 Hz other fans slow down to 4000 + cfm while this fan still puts out 8000 cfm! Built-in computer controls pressure or flow.
