Q: What is the airflow rate (CFM) of this vacuum pump? Is it suitable for maintaining domestic air conditioning systems?
A: This pump has a flow rate of 3.5 CFM and an ultimate vacuum pressure of <20 Pa. This makes it ideal for the rapid evacuation of air conditioning systems in homes and vehicles. It far exceeds the requirements of DIY enthusiasts.
Q: How loud is the pump? Will it disturb the work environment?
A: The noise level is ≤70 dB (comparable to normal conversation). Thanks to its noise-reducing die-cast aluminum housing, it operates more quietly than comparable pumps with iron housings. Suitable for use in garages, workshops, and other enclosed spaces.
Q: What does the current protection do?
A: The built-in 3A overload protection automatically shuts off the pump in case of unstable voltage or motor overheating, thus preventing motor damage. After maintenance, simply press the reset button to restart the pump.
Q: What pipe diameters is the intake manifold suitable for? Do I need to buy an additional adapter?
A: The standard intake connections are 1/4" SAE and 3/8" SAE and cover 90% of AC hose specifications.
