BACOENG 1 1/2 Gallon Vacuum Chamber Kit with 3.6 CFM 1 Stage Vacuum Pump HVAC

I purchased this for degassing silicone and it works great! Follow the instructions because it sounds like you can break the pump if not used properly. I used this multiple times a day for about two years without issues. The only reason I'm retiring it is because I needed a larger chamber. This ended up being a great starter unit that I could depend on for daily repeated use and I highly recommend it.

Manche de couteaux

No se si haya mejores marcas de estas bombas, yo la he visto en videos y funciona bien para desgasificar el caucho de silicón, en lo personal siento que debería resistir mas vacío, trabajé al vacío máximo recomendado y aún así siento que tarda demasiado en desgasificar. La olla de tres galones se escucha espaciosa pero ya viéndola y en el uso, termina siendo pequeña... no quiero imaginarme la olla de un galón

My first vacuum chamber, and one I bought on recommendation from a friend. The first pump I received was broken in a strange way- it functioned, but leaked oil all over. Thankfully, it was swapped out when I reached out to support, no issues. The new one works perfectly, however I don't have too much faith in the valve stems, which are somewhat wiggly when I go to open or close them. I've not had any issues of leakage, but I am warning you to be gentle with them. Decent little starter! Also, to resin newbies- if you're trying to remove bubbles, a pressure pot is better than a vacuum chamber, unless your pour is something that's pretty flat. So, dicemakers should opt to look into pressure, instead, and follow every direction on the pressure pot- they are a bit more dangerous than a vacuum chamber!

This is the third unit I have ordered from Amazon and all three had to be returned. The first one was perfect out of the box, but would not pull a vacuum unless I pressed down on the lid with both arms extremely hard. I tried going through customer service, but after several days with no response I just made the exchange through Amazon. The company rep did finally get back to me and said they did not have any 3 gallons in stock, but offered a different type of chamber that didn’t fit my needs. When the Amazon replacement arrived, it was clearly a used unit. Oil already in the reservoir, residue build up on the fittings, and other obvious signs of previous use. Sent that one back for a refund. Company rep told me to return it for refund and order a new one, so I did. Third unit arrived and the valve housing fitting was cracked right out of the box!! The bottle of oil was sealed, but dirty like it had been on the floor of a jiffy lube all day. It appears to me that they do not have stock in the US right now and are either selling their scratch & dent units (B-stock) or are taking the working pieces of warranty returns and piecing together the kits to sell as new units. If that’s not the case, then the quality of this product is just not what everyone is raving about in previous reviews.
