"OSHA valves are sized for the pressure and flow rate required by the tools to be used," says Massinon. "For this reason there is no one-size- fits-all OSHA valve. That's why OSHA valves are not a standard feature supplied on portable compressors." Filters and water For many applications you will want an air filter and water separator on your air compres- sor. Compressed air inevitably contains small amounts of dirt, water and oil that can damage tools or interfere with finishes. Clean, dry air is good for any application but aftercoolers and water separators are essential for paint and sandblasting opera- tions. If you have a compressor with a filter and condensate remover, be sure to check them every day. Tier 4 maintenance Most of your typical 185 cfm/100 psi portable air compressors use engines small enough that they don't need diesel exhaust fluid or a diesel particulate filter to clean their exhaust emissions. But ask about the engine main- tenance requirements before you head down the highway, espe- cially if you are towing a larger compressor. If your system uses diesel exhaust fluid you'll probably need to fill the reservoir once for every tank or two or three of diesel you burn. And a diesel particulate filter may need pe- riodic regeneration to burn off the accumulated soot inside the filter. On some models this may require you to cease work until the regen is completed.
