Yellow Jacket, a Ritchie Engineering Company, is a proud manufacturer of built in the USA Vacuum Pumps. The Yellow Jacket Bullet series is their economical line of vacuum pumps but that doesn’t mean they are cheaply made. These vacuum pumps are available in 3, 5, and 7 CFM Models depending on the size of the system you are looking to evacuate. They all feature a wide base with rubber legs to keep them in place during use. The Yellow Jacket Bullet pumps feature a ½ hp 1725 rpm motor and are a 2-stage rotary vane design. Each Yellow Jacket Bullet Vacuum Pump is rated to pull down to 25 microns or better. The Yellow Jacket Bullet line of vacuum pumps have a few subtle upgrades that give them longevity in the field. First they have a wide mouth oil reservoir and large oil drain that make changing the oil easier and faster than ever. They have also added intake filter screen to prevent particles from entering the pump. These features along with the heavy-duty bearings and rotors help make the Yellow Jacket Bullet Vacuum Pump a quality, long lasting pump that will be a workhorse for many years.
