Tru-FlateÂ® airline filters are used for all airline applications where efficient filtration is required. Filtration removes airborne solid contaminants, pipe scale, rust, which may cause wear or failure of pneumatic components. Large filter element surface gives low pressure drop and long element life. The mini series of airline filters offers a higher degree of filtration. All filters are complete with filter element and either manual or automatic drains. Maximum pressure 150 psi at 125 deg F with polycarbonate bowl and 250 psi at 175 deg F with metal bowl. Temperature range -10 to +175 deg F.
