Brushless DC compressor with variable flow at pressure output

Thomas Division has designed a compact, high performance brushless DC compressor, for applications with a higher performance to weight ratio requirement.


The brushless DC 2450Z Series compressor from Thomas is designed for medical and other applications requiring a small, lightweight pump (6.8 lb vs 9.5 lb ac motor) with a higher performance to weight ratio. The 2450Z features a small footprint (8.32 in. x 6.75 in. x 4.08 in.) and an efficient variable output brushless 140 V dc motor that conserves power, and energy, by matching the output of the compressor to the application’s requirements. In addition, the 2450 Series is quiet (50 dB(A) @ 20 psi) and features a balanced stroke design and center-line of gravity mounting to minimize vibration and cost of vibration isolation. The oilless 2450 Series is also RoHS compliant and features permanently lubricated bearings, as well as the long-life, proven performance of Thomas’ WOB-L piston technology.

Maximum flow is 3.3 CFM @ 2200RPM. Maximum pressure is 35 PSIG.
