SUCTION AND RETURN FILTERS SERIES HF 620 - 625
PRESSURE DROP CURVES
The pressure drop for filters series HF 620 on suction line is 0,2 bar max; the pressure
drop for filters series HF 620 and HF 625 on return has to be between 0,2 and 0,4 bar.
1) The by-pass pressure drop is directly proportional to fluid specific gravity and it’s
irrelevant to determine the total pressure drop.

3) The filter element’s pressure drop is determined by standard media and AS surface,
they have been calculated experimentally and thy are valid for clean elements.
