Constant pressure and constant airflow blowers automatically adjust to maintain optimum performance levels in changing conditions. The 180x180L EC double-inlet models are CE-approved and meet ErP 2015 efficiency requirements. The forward-curved centrifugal blowers, designated the GDSV8 Series, are powered by 230 V single-phase, 50/60 Hz EC motors. They run at speeds as high as 2255 rpm and generate a maximum airflow of more than 1000 cfm at free air. Speed control is possible through pulse-width modulation, 0 to 10 VDC, or a potentiometer.
