Brushless dc WOB-L air compressors and vacuum pumps are for medical applications requiring a small-size and lightweight pump with variable output. The 250 series pump is extremely small (4.25 × 4.54 × 3.02-in.) and weighs only 1.9 lbs. In addition, the 260 Series features variable output (1,000 to 3,000 rpm) using an efficient brushless dc motor, an enclosed crankcase for reduced sound, and the proven reliability of Thomas' WOB-L piston technology.
