As wet, contaminated air is drawn through the unit, the hydrophobic media repels water while the particulate filter captures dirt, preventing both from entering the equipment (ND-2).
As wet, contaminated air is drawn through the unit, the hydrophobic media repels water while the pleated particulate filter provides a large surface area and protects against particulate contamination. The unit also blocks free water from the reservoir (ND-35).
