Customer Reviews for 4 Cfm 1/4 Hp Air Conditioner Vacuum Pump With 3 Gallon Vacuum Chamber

Easy to use,accurate pressure gauge clear see through lid

Bought this for degassing epoxy and it does a wonderful job. There are probably better (and more expensive) ones, but it's for our hobby and we are very happy with it.

This was my first major purchase from Vevor so I was a little aprehensive as to the quality of their goods. In all fairness I needn't have been, the vacuum chamber was sizeably bigger than I had in my head not being familiar with anything gallon based (being in the uk). It was plenty big enough for my usage and assembly was a breeze I cannot fault this product in the slightest. The furnace had a little kink in the outside mesh but this is purely cosmetic and affects the functioning of not one bit. I have yet to melt metal in it but I feel very confident that it will perform handsomely, the free crucible tongs that match the style of crucible are such a nice touch and save you more money on a bargain priced item. In this case bargain price does NOT mean cheap and nasty, this thing is well made and it is weighty instilling confidence in its construction.

Excellent! Have been using it with silicone and resin. No problems. Works fast and holds pressure. Pump is fairly quiet and the unit it easy to assemble out of the box.

Nothing really bad to say about this. Quiet, surprisingly fast in creating vacuum. Removed bubbles from my resin in few minutes. Recommended.

I'm a hobbyist just looking for a good quality tool for a relatively good price. Bought this kit to degass silicone. Delivery was fast with my order arriving just in a few days during the working week. I'm happy with the product but I am by no means an expert on vacuum chambers. Easy to assemble but you will need extra tools to put the kit together; the main tools being an adjustable wrench and a Phillips screwdriver. You'll also need to buy 'HFV 32' vacuum oil as the pump in the kit has very little. The instruction manual given in the kit is small and too vague; when it came to putting the washers on, the manual did not specify which of the two washers (rubber or metal) should go in which order. There is a Youtube video for this luckily: https://www.youtube.com/watch?v=KpxSuHwOyMk If you buy this equipment on another site for a cheaper price, do understand that Vevor's return and replacement policy will not apply. That means you'll have to trust your seller for refunds or replacements.

The item works well and if there are any problems the seller is responsive and prompt

Die Pumpe ist super leise. Habe gestern Abend gegen 19.00 Uhr die Luft aus der Kammer gezogen, habe heute 14.00 Uhr nachgeschaut ob sie dicht ist. Der Zeiger vom Vacuumeter hat sich kein mm bewegt. Super dicht die Kammer. Ist zu empfehlen.

Me encanta. No es demasiado grande y ya lo use unas cuantas veces y va perfecta. Todo como lo esperaba. Muchas gracias.
