Compressed air treatment equipment assist pneumatic equipment to control and improve the quality of compressed air. Raptor Supplies offers these units from brands like ARO, Dixon and Air Systems International. The refrigerated compressed air dryers remove oil aerosol and water vapours to deliver a dry and clean compressed air steam. Further, the air line lockout valves eliminate accidental startups of air-operated devices, compressed air filters purify the air stream by trapping moisture, dirt and other impurities, whereas the compressed air lubricators help minimise wear on pneumatic components. The compressed air regulators evaluate and monitor air pressures and are available in a maximum pressure rating of 450 psi on Raptor Supplies.
