Large and mid size building test kit. Carry the lightweight components under your arm and set up in minutes in any doorway. Ideal for TM23 testing UK standards up to 4,800 m2 floor area or for pressurizing large buildings for thermography. Heavy duty commercial 3 phase fans will run all day at any speed without over heating. The Variable Frequency Drive creates the 3-phase power but uses regular single phase wall outlet power; either 110 or 240 Volts!

Retrotec Model QMG consists of one DM-2A, one DM-2, three 3300 Fans and a Light weight hard door panel for 3 fans. Add fan cases, software, grill mask and accessory options.

One DM-2A measures and controls one fan automatically, a second DM-2A displays flow pressure for the other two fans. A third DM-2 could optionally be added so that each fan would display the flow for that particular fan.

Three 3300 Fans have 3 variable frequency drives that run 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.
