Frequently Asked Questions
How does this compare to single-stage vacuum pumps?
The two-stage design pulls deeper vacuum levels reaching 35 microns compared to single-stage pumps that typically only achieve 100+ microns. The second stage starts pumping at lower pressure, allowing better ultimate vacuum and more thorough moisture removal from HVAC systems for professional results.
What size air conditioning systems can this pump handle?
This 5 CFM pump is rated for air conditioning systems up to 50 tons or 176 kW capacity, making it suitable for large rooftop commercial units, tractor-trailers, buses, and residential applications. The high CFM rating ensures fast evacuation times even on larger systems.
How often should I change the oil?
Change the oil after every 8-10 uses or when the sight glass shows dark or contaminated oil. The angled drain valve at the reservoir bottom and accessible top fill port make oil changes quick and complete, requiring only 7.5 oz of vacuum pump oil per change.
What refrigerants and oils are compatible with this pump?
This pump works with CFCs, HCFCs, and HFCs in conjunction with mineral oil, ester oil, alkyl benzene oil, and PAG oil lubricants. It is not compatible with ammonia systems, lithium bromide applications, or A4L and other flammable refrigerants for safety reasons.
