The Robinair 15500 VacuMaster is a 5 CFM automotive vacuum pump with a two-stage rotary vane that pulls down to 35 microns, stripping moisture out of A\/C and refrigeration systems fast enough to keep your schedule on track. Whether you're servicing rooftop commercial units, pulling vacuum on tractor-trailer reefer systems, or doing a car ac vacuum pump job in the shop bay, this one unit handles it all with capacity rated up to 50 tons.\u003c\/p\u003e\n    \u003cp\u003eSingle-stage pumps leave moisture behind. The 15500's two-stage design pulls deeper and gets there faster, so you're not sitting around waiting to hit target vacuum on a system that should've been done ten minutes ago. A sealed-bearing, high-torque motor fires up reliably even after sitting in your van all weekend, and the cast aluminum body keeps weight at 28 lbs. Light enough to haul up a ladder. Tough enough to survive bouncing around in a service truck.\u003c\/p\u003e\n    \u003cp\u003eOil maintenance is where a lot of pumps waste your time. Not this one. The angled drain valve at the bottom empties faster and more completely than standard drains, the top fill port gives you easy access when topping off, and a large sight glass shows both level and condition at a glance. Brass intake valves with 1\/4\" MFL and 3\/8\" ACME fittings connect to the manifold sets you already own. An intake screen blocks debris from the pumping chamber, and the external exhaust filter separates oil vapor from exhaust flow to keep internals clean.\u003c\/p\u003e\n    \u003cp\u003eGarage Supply Guys carries Robinair vacuum pumps with direct support from people who know the equipment.
