Frequently Asked Questions
The industry standard target is 500 microns or below. For new system installations, many manufacturers require 300 microns or below to validate the warranty. The SRG4 displays real-time readings so you know exactly when you've reached the target.
Yes. The SRG4 connects via a standard 1/4" SAE flare fitting and works with any HVAC vacuum pump. It's compatible with the Fieldpiece VP85 and all other professional-grade vacuum pumps.
Yes. The SRG4 measures vacuum (not refrigerant type), so it works with all refrigerant systems including new R-454B equipment. Proper evacuation is especially important for A2L refrigerant systems to prevent moisture contamination.
