The Yellow Jacket BULLET DC Vacuum Pump features a brushless DC (BLDC) motor, capable of providing high torque and high efficiency. The unit functions in extreme low voltage conditions and is field rated to 25 microns. 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.
