Why is my Wood-Mizer Ventilation Hood losing suction?
- EErik JohnsonAug 5, 2025
Suction loss in your Wood-Mizer Ventilation Hood can occur due to several reasons: increased static pressure or resistance (caused by dirty filters, sharp bends in hosing, or excessive hose length), low airspeed (due to unused inlet ports), leaks in the system, or the impeller spinning in the wrong direction. To resolve this, clean or replace dirty filters, remove sharp bends in the hosing (keeping bends larger than 45 degrees when possible), minimize hose length by moving the extractor closer to the workpiece, block any unused inlet ports, use blast gates to increase suction in specific areas, ensure all connections are airtight (using silicone caulk or duct tape if needed), and verify the impeller is spinning toward the outlet by consulting the wiring diagram.
