I’m brand new to making composites and I’m looking to start out doing some resin infusions and maybe some prepreg down the line.

As I’m new to this hobby I don’t to spend too much money on a vacuum pump as I’m unsure if It’s a hobby I’ll really get into or not.

I had been told by my brother I needed a dual stage pump (I’m assuming he meant for infusions).

I was looking to do quite small jobs. I’m not making boats, probably never do any car sized panels, but a bit smaller.

Do I really need a dual stage pump?

For reference the pump I was looking at was “4.5CFM 2 Stage Refrigerant Vacuum Pump Refrigeration Air Condition 128L/MIN” made by VEVOR.


Any help would be appreciated

No, single stage (oiled) rotary vane pumps are sufficient. 0,3 is a relatively normal number for dual stage pumps. But you will not need such a high vacuum. You could use it, but a cheaper single stage pump will do the job equally good.

Ok that’s great, thank you and everybody for the advice on this, think I’ll get one of these cheapy pumps.

Does anybody actually use one of these VEVOR pumps?
