Parker Hannifin Corporation recently released a line of pneumatic stainless steel filters, regulators and lubricators. The Parker Prep-Air Stainless Steel Series of air preparation units is designed for protecting pneumatic system components in corrosive and washdown applications. Parker FRL air preparation units feature high flow rates and standard fluorocarbon seals, and are suitable for systems with pressures up to 300 pounds per square inch gauge (PSIG). Prep-Air II air line filters are available in miniature (Âº-inch port size) and standard (Î©-inch port size) models, and feature a two-stage filtration system. Coalescing filters, also available in miniature and standard models, use a thick membrane of “borosilicate” glass fibres coated with epoxy to remove liquid aerosols and sub-micron particulate matter. Prep-Air II pneumatic regulators have a large diaphragm-to-valve area ratio for precise regulation and high flow capacity. Regulator adjustment mechanisms and springs are made of 316 stainless steel, with fluorocarbon diaphragms and seals. Models are available with Âº-inch and Î©-inch ports. Pressure adjustment ranges are available from zero to 250 PSIG. Parker Prep-Air II air line lubricators supply a controlled state of oil delivery to the pneumatic system. The oil delivery rate increaseslinearly with the increase of air flow. The standard port size is Î©-inch.
