The Jet Industrial Air Filtration Systems, Nos. 415100, 415125, and 415155, are designed to remove processed dust, oil mist and fumes, and other industrially generated airborne particles. The units are constructed of metal and have a fully enclosed ball bearing motor with overload protection for long, dependable service. The pleated fiber air filter is 99 percent effective with filtering oil mist, fumes, and water vapor based on eight to 10 micron size particles in the air, the company says. The two-filter inner system with air diffuser disperses outgoing air into a broader pattern. In addition, the metalworking specific outer filter attracts more oil mist, smoke, and dust generated during the metal process.
