Frequently Asked Questions

Q: How does this compare to single-stage vacuum pumps? A: The two-stage design pulls deeper vacuums by activating the second stage at lower pressures, achieving better moisture removal than single-stage pumps for more thorough system evacuation. This results in faster pump-down times and better protection against compressor damage from residual moisture in A/C and refrigeration systems.

Q: What size A/C systems can this vacuum pump handle? A: The 15150 works on passenger cars, light trucks, and domestic refrigeration systems up to 10 tons or 35 kW capacity. It handles most automotive A/C systems efficiently but is not suitable for large commercial HVAC systems over 10 tons or specialized applications using ammonia or lithium bromide refrigerants.

Q: How often does the oil need to be changed? A: Oil change intervals depend on usage frequency and contamination levels, but the angled drain valve and sight glass make monitoring easy. Heavy commercial use may require changes every few months, while light residential service can extend intervals significantly. Always check oil color and consistency regularly for optimal pump performance.
