Es un buen producto cumple su función ya hice el vacio a dos aires de auto y todo muy bien El único inconveniente q tuve fue en una llave del manómetro esta como barrida cuando la abres ya q no llega a un tope solo es cuando la abro Por lo demás funciona muy bien

fonctionne trais bien j'utilise régulièrement je la recommande

Used for two different heat pump installations: a 18000 Btu and a 6000 Btu and it vacuumed both efficiently - one year apart. So it was still working great after a year in storage. I replaced the vacuum oil after that year - as recommended by the manual. Replacing the oil involves running it for about 15 mins to warm up and loosen the oil, then a hex screw to the front (have something to catch it ready underneath). The hoses and gauges worked for a nitrogen 300psi pressure test as well. Everything seems good quality - and held up to storage for a year in between uses. Would definitely recommend! If you plan on using the gauges for a pressure test, just keep in mind that some newer heat pumps recommend pressure testing at about 500psi which is beyond the accurate range of this gauge.

Me ayudo bastante en cargar el gas a mi auto, haciendo vacio a la línea! Muy recomendable!

I tried to change pump and condenser without a vacuum pump. Worked for about 15 mins, then vapor locked. Put on the pump and ran it 2 hours, had air since. What's not to like?
