Our scoreSCORE7.3 / 10Not reviewed yet
Our takeThe same pump without the overflow switch. We'd spend the little extra on the ULS for anything near a finished floor.Our default for a first flare install: a two-stage 5 CFM pump listed as sparkless for A2L refrigerants like R-454B and R-32. Pair it with a micron gauge, because the pump alone can't show you 500 microns.
