Polycarbonate Bowls

Although air line lubrication is not required for some valves, other mechanisms in the system may need such lubrication. When a lubricator is used it should be supplied only with oils which are compatible with the materials used in the valves for seals and poppets. Generally speaking, these are petroleum based oils with oxidation inhibitors, and aniline point between 180¼ F (82¼ C) and 220¼ F (104¼ C) and an ISO 32, or lighter, viscosity. Oils with phosphaste type additives, such as zinc dithiophosphate, must be avoided because they can harm polyurethane valve components. Some of the available compatible lubricants are listed below. However, oil manufacturers sometimes change the chemistry of their oil. The oils listed, although believed to be compatible at the time of printing, could change without notice. Therefore, the best oils to use are those specifically compounded for air line lubricator service.

Cautions on the Use of Polycarbonate Plastic Bowls

Use Only with Compressed Air. Filter and lubricators with polycarbonate plastic bowls are specifically designed for compressed air service, and their use with or injection of certain hazardous fluids in the system (e.g., alcohol or liquified petroleum gas) could be harmful to the plastic bowl or result in a combustible condition or hazardous leakage. Before using with fluid other than air, or for non-industrial applications, or for life support systems, consult CAS.

Use Metal Bowl Guard When Supplied. A metal bowl guard is supplied with all but the smallest bowls, and must always be used to minimize danger from fragmentation in the event of failure of a plastic bowl.

Avoid Harmful Substances. Some compressor oils, chemical cleaners, solvents, paints, and fumes will attack plastic bowls and can cause bowl failure. Do not use with or near these materials. When a bowl becomes dirty , replace the bowl or wipe it with a clean, dry cloth. Immediately replace any plastic bowl which is crazed, cracked, or deteriorated.
