The BlackMax® VPBM4V is a compact, professional 4 CFM vacuum pump engineered for modern refrigerants including A2L classes. A 1/2 HP brushless DC motor delivers variable-speed performance and quiet operation, while universal 100–240 V (50/60 Hz) input eliminates voltage-selector hassles. A mist-free exhaust/oil-fill cap, large vertical oil sight glass, and analog vacuum gauge simplify service. The plated-brass gas ballast reduces moisture in oil to stabilize deep vacuum performance down to 15 microns. With 1/2" M, 3/8" M, and 1/4" M intake ports and an auto shut-off solenoid valve that prevents oil backflow, VPBM4V is built for reliable, ignition-proof operation in extreme temperatures.
