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 3.5 CFM and an ultimate vacuum pressure of < 50 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 and 1/2" ACME, covering 90% of AC hose specifications. For special connections, you can pair it with commercially available adapters (like 3/8" NPT).
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.
