The PM60A air-cooled vacuum pump from Moro USA weighs 265 pounds, has 29 psi positive pressure capability, 198 cfm free airflow at 1,100 rpm, and a suggested tank size between 500 to 2,500 gallons. It has a cast iron body with visual inspection ports and employs radial rotary Kevlar vanes to provide vacuum/pressure, and a direct-feed sealed oiling system. Its large, open-ported manifold design reduces noise and air friction. The cantered rotor produces ideal vacuum and pressure by preventing air from slipping past the vanes. Viton oil seals and low rotating speed leads to longer pump life. It can be easily mounted on a truck frame and connected to the truck drive system, or can be delivered in preassembled pump packages for special applications. 800/383-6304; www.morousa.com.
