The Brushless DC (BLDC) Motor incorporated in the next generation BULLET�DC Vacuum Pump provides key advantages over existing AC technology vacuum pumps. High torque and high efficiency define the ultimate performance in the most reliable vacuum pump. Able to function in extreme low voltage conditions and field rated to 25 microns, the BULLET�DC is the perfect combination of quality and value. The easy to carry, lightweight design is available in 7 cfm to handle most residential and commercial applications. Pulling down to less than 25 microns, BULLET�DC protects the system from contaminants and non-condensable gases, which can damage components, reduce efficiency and cause system failure.
