Systemair DVCI 190E-P EC - Centrifugal roof fan, <125W, vertical discharge, insulated

100 % speed controllable Integrated motor protection Low noise level Safe and maintenance free operation Energy-saving The DVCI-P roof fans are driven by EC- external rotor motors, so called energy saving motors with high efficiency. The input voltage for single phase units can vary between 200 and 277V, for three phase units between 380 and 480V. All motors are suitable for 50Hz and 60Hz and from size 355 up to 710 suspended on effective vibration dampers. Motor protection is integrated in the electronics of the motor, no additional external motor protection device is needed. The DVCI-P versions have integrated pressure sensors and the electronics are programmed for a pressure constant operation. Casing from seawater-resistant aluminum with an 50 mm mineral wool insulation for low noise level, base frame from galvanised steel. Backward curved impellers manufactured from polyamide PA for size 190 and 225. From 315 up to 710 impellers manufactured from polypropylen PP.
