When residential duct testers tap out… this one keeps going.

1700 watts of controlled power drive this 20 lb (9 kg) commercial system — delivering up to 295 CFM at 8 in. w.c. (≈1,400 Pa).

That means higher static capability, larger duct systems, and fewer work-arounds on commercial jobs.

Included is the DM32X touchscreen digital manometer — the control center for your duct tester and blower door (Retrotec or TEC). One gauge. One interface. Total control.

Color-coded tubing. Color-coded wiring. Touchscreen setup. Faster deployment. Cleaner data. Professional results your reports can stand behind.
