  • COMPLETE VAC CHAMBER SET: This professional degassing kit from Orion Motor Tech includes a 3.5 cfm pump, a 3 gallon chamber, a wire hose, and all the accessories needed to quickly, easily, and safely handle removing air and other gases from resin, epoxy, oil, and other solvents
  • 3.5CFM VACUUM PUMP: This set's single-stage rotary vane pump is powered by a 0.25 hp all copper motor to keep your degassing humming along; with its dual ports and included adapter, it also works with HVAC gauges and hoses to draw down car and low-tonnage AC systems to as low as 37.5 microns (5 Pa)
  • 3 GALLON CHAMBER: The vacuum chamber is constructed from brushed 201 stainless steel for superior durability and resistance to pressure, corrosion, and heat up to 248°F; the transparent acrylic lid and provided gauge allow easy monitoring at every stage of the degassing process; and a non-skid pad prevents noise and rattling during use
  • HELPFUL ACCESSORIES: This vacuum pump and chamber set comes with the system's necessary lubricating and absorptive oil included, as well as a funnel and one-size-fits-most gloves for quick and clean replacement; an adapter allows use of the pump with 1/4", 3/8", or 1/2" HVAC hoses as needed; and a 5 ft. reinforced wire hose and various gaskets, filters, and fittings provide a reliable connection between pump and chamber

Shipping was awesome, the company went above and beyond. Great care was taken to ensure that I received the product in one piece. I’m still waiting to use as I don’t have any projects going right now but I’m that I will not be disappointed at all….

Very nice unit

So far works as advertised. I have only used it a few times but worked well. The directions had one flaw as installing a metal washer to underside of the glass during gage mounting. Be sure you use a provided gasket directly on the glass...then the metal one behind it. Don't put the metal washer against the glass...other than that so far so good.
