Fan Power Consumption. The ideal power consumption for a fan (without losses) can be expressed as. P i = dp q (1). where. P i = ideal power consumption (W). dp = total pressure increase in the fan (Pa, N/m 2). q = air volume flow delivered by the fan (m 3 /s). Power consumption at different air volumes and pressure increases are indicated below:
