1/2 HP Vacuum Pump, Reliable Power


Delivering 5 CFM airflow and a 0.3 Pa ultimate vacuum with a 1/2 HP motor, this vacuum pump gets the job done quickly. Its durable cooling design, visible oil window, and multiple air inlet port options make it ideal for HVAC servicing, resin degassing, and wood stabilization.
Q: What is the free air displacement (CFM) of this vacuum pump? Is it suitable for home AC maintenance?
A: This pump has a flow rate of 5 CFM and an ultimate vacuum pressure of < 30 Pa, making it ideal for quickly evacuating home and vehicle AC systems. It far exceeds the needs of DIY users.
Q: What pipe diameters does the inlet port accommodate? Do I need to buy an additional adapter?
A: The standard inlet ports are 1/4" SAE, 1/2" ACME & 3/8" SAE, covering most of AC hose specifications.
Q: How loud is the pump? Will it disturb the work environment?
A: The noise level is ≤ 70 dB (comparable to normal conversation). Featuring cast aluminum housing for noise reduction, it operates quieter than similar pumps with iron casings. Fit for use in garages, workshops, or other enclosed spaces.
