The Robinair 15401 4 CFM Vacuum Pump is a two-stage, rotary vane pump designed for use on A/C-R systems using CFCs, HCFCs, and HFCs in conjunction with mineral oil, ester oil, alkylbenzene oil and PAG oil as lubricants. It is not for use with ammonia or lithium bromide systems; not for use with flammable refrigerants.
The pump features a two-stage design with a second stage that starts pumping at a lower pressure to pull a deeper ultimate vacuum. This helps to ensure that the system is completely evacuated and free of contaminants. The pump also features an offset rotary vane design that creates the deep vacuum conditions needed for a thorough evacuation.
The Robinair 15401 4 CFM Vacuum Pump also features a gas ballast feature that helps to keep the pump oil clean by reducing condensation of moisture. This helps to extend the life of the pump and ensure that it is operating at peak efficiency.
The pump also features an Iso-ValveTM that isolates the pump from the system with just a 1/4 turn, making it simple to measure rate of rise. This feature is also helpful for troubleshooting problems with the system.
The Robinair 15401 4 CFM Vacuum Pump is equipped with an integral check valve that prevents pump oil from being sucked into the system if a power loss occurs. This helps to protect the system from contamination and damage.
The pump is constructed with a die-cast aluminum housing that is lightweight but durable. It also features a molded base that improves pump balance and minimizes vibration.
The Robinair 15401 4 CFM Vacuum Pump is available in 110-115V/220-250V (selectable), 50/60 Hz, and has a flow rate of 93 l/m at 50 Hz.
