Cloth Panel Systems : Q4E Automated Blower Door

Retrotec Model Q4E consists of a DM-2A, a 3300 Fan and a cloth door panel. Add fan case, software and accessory options.

DM-2A 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.
