Oiler, filter for air powered tools
Iowan Carl Greenwood, Jr., put together this portable automatic oiler and moisture-removing air filter that hooks up between air-powered tools and air compressors. It eliminates the need to manually add oil to air tools and also removes moisture from the air line to keep tools from rusting out. In addition, the unit has a pressure regulator that lets him slow down the operating speed of air tools.
The "Air Witch", as it's called, consists of a 50-lb. aluminum frame fitted with the pressure regulator, air filter, automatic oiler and three quick couplers. One coupler hooks up to the air compressor, another hooks up to tools, and a third, which by-passes the automatic oiler, can be used to run a paint sprayer.
"A big problem with air tools is that moisture gets inside the tool and causes rust. The filter keeps moisture out of the line," says Greenwood, of Farley. "The oiler automatically lubricates the tool and eliminates the need to stop and add oil every h ilf hour or so. We shut the oiler off whenever we hook up the paint sprayer, but we leave the air filter on. It keeps moisture out of the paint so it won't bubble up."
The pressure regulator lets Greenwood operate air tools at slower speeds so they won't wear out so fast. 'We simply set the regulator at whatever pressure we want and lock it in place. The slower working speed also helps keep us from stripping sockets on our air impact wrenches."
Making the accessory unit portable lets Greenwood use it in the field with his port-able compressor, and back in the shop with his wall-mounted compressor.
Greenwood spent about $160 to build the Air Witch.
