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 <20Pa, making it ideal for quickly evacuating home and vehicle AC systems. It far exceeds the needs of DIY users.

Q: How loud is the pump? Will it disturb the work environment?

A: The noise level is ≤70dB (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. 

Q: What does the current protector do?

A: The built-in 4.5A overload protection automatically shuts off power if there is unstable voltage or motor overheating, keeping damage from the motor. Simply press the reset button after maintenance to restart the pump.

Q: Is the vacuum chamber seal reliable? How can I check it?

A: Test Methods: Soap Water Test: After vacuuming the chamber, close the valve and apply soapy water along the lid’s edge. No bubbles indicate a reliable seal. Pressure Test: Vacuum the chamber to 20 Pa, then let it sit for 30 minutes. If the pressure rise is ≤5 Pa, the seal is deemed satisfactory.
