Electric Pedal Fan, pay attention to keeping the fan horizontally positioned during installation. The weight of the return air duct and valve should not be placed on the housing. Selection of the fan type should

Based on the air volume and pressure loss of the inlet air system, determine the separate calculation of fresh air volume and pressure loss during clean ventilation and filter-toxin ventilation.

New airflow rates and corresponding pressure losses at those rates. If clean air ventilation and filter-dust ventilation share a single fan, the calculation should be based on the combined airflow rates and their pressure losses.

Select a fan for power loss; if clean ventilation and filter ventilation are separately set with inlet fans, the fan should be selected based on the fresh air volume of clean ventilation and its pressure loss, as well as the filter ventilation.

An inlet fan selected for its air volume and pressure drop.
