An air purification unit spends its life fighting a dirty filter: resistance climbs as the media loads, and a weak fan just slows down, starved for airflow. The YEM is sized for that condition. Its forward multi-blade wheel, 120-280 mm, moves 50-3,000 m3/h at pressures up to 1,000 Pa - the pressure reserve keeps output steadier as filter pressure builds over time. Motor power runs 10W-950W, covering everything from small residential terminals to medium fresh-air boxes.
EC motor and control
Motor and controller sit together, so there is no external VFD to add to the equipment enclosure. Control is VSP/485; the fan can follow a thermostat, CO2 reading or purification cycle schedule rather than holding one fixed speed. Direct drive means no belt or pulley to service. Insulation grade B, working temperature -25 C-60 C, suited to indoor fresh-air and purification environments.
Where it shows up
Fresh air units and air purification systems are the stated use, installed in homes, offices, schools and commercial buildings where filtered fresh air matters. When selecting, tell us the filter grade and final expected pressure drop; the 1,000 Pa value should leave headroom once the filter has loaded in service.
