Which vac pump
I`m thinking of buying a new vac pump but the more I look the more I`m confused by the wide variety: 50 microns, 25 microns 15 mcrons; 3,5,6 and 8 cfm. Obviously the lower the micron rating the better but it seems the cfm goes down. So what do you guys recommend for around £300. I`m working on commercial splits mainly so something to cope with typical (if there is such a thing) pipe runs.
Thanks guys,
Glenn

Re: Which vac pump
Duel voltage here refers to 220/110v. We all use the Robinair 4cfm

Re: Which vac pump
Why do you need 110v in England for?

Re: Which vac pump
110v is the preferred option on building sites across the UK.
The difference between genius and stupidity is that genius has its limits.

Re: Which vac pump
If we are working on a construction site all portable tools need to be run off of a 110v transformer, its a 2x 55v supply, the idea being we shouldn't be able to kill our selves with that voltage.
So a dual voltage pump allows for 110v site work an 240v when we can't be ar$ed to get the transformer out of the van
I'm happy with my Yellow Jacket vac pump, no need to go to big with the cfm rating as gauge lines don't flow well enough for it to make much difference.

Re: Which vac pump
Nonsense, even 24V can kill.
Its the amps that kill you.
All you need is an RCD on the extension cable and you are safe.

Re: Which vac pump
Thems the rules, nonsense or not. Have even heard of 36v battery drills being banned from site. We have to have those yellow jackets, hard hats, safety shoes, gloves, fibre glass steps, it goes on.
In one office their health and safety officer insisted i had four traffic cones with hazard tape round them, a fibre glass ladder and someone standing by just incase so i could measure the air on and off temps and write down the model number on a cassette, i had to have a site induction and fill out a form before the even let me do this...
The UK is run by numpties, and its the working man that has to put up with it, or move abroad which is looking increasingly attractive as time goes by

Re: Which vac pump
You can't go wrong with a yellow jacket, I've got two of them, built like tanks. The robinair ones are pretty good as well.

Re: Which vac pump
Many places don`t allow stanley knives on site now. On one site induction I was even asked if I knew the correct way to use a spanner. Oh and on two sites I got to I can`t wear riggers boots incase something hot falls inside them

Re: Which vac pump
The best vacuum pumps available have got to be Edwards (Used to be BOC Edwards), the old EM Series being the best..
The smaller sizes are only available reconditioned now though, although i think the speedyvac 2 is still available new..
They arn't cheap though, but in my own experience they last alot longer than any other make, duel voltage motors & spares/rebuild kits are readily available..
Tried to post links, but cause i'm a newishbie computer say's no.. Google- Edwards High Vacuum or Absolute Vacuum Services..
Apart from these the yellow jacket ones are pretty decent for the money..
'elf & safety has gone crazy in the UK, think the compensation culture is largely to blame for this myself..
Got chucked off a site in 08 for not wearing sunglasses while working on a roof, to their surprise i was only to happy to leave & made my own decision not to go back..

Re: Which vac pump
Yellow Jacket's SuperEvac pumps are all rated at 15 microns. The 6 CFM is usually the best bang for the buck. If you have some time to spare, their new Bullet pump will get you 8 CFM for the same price (or less?) than their 6 CFM. I think it will ship in April.

Re: Which vac pump
Yellow Jacket are not represented in my country, I am not familiar with your stuff.
It could be very good, or not. I am very pleased with my pump.

Supco International represents Yellow Jacket in Israel. If you want, I can provide contact details.

Re: Which vac pump
Had 2 robinair 5cfm never let me down in 11 years of use until retired, a mastercool 6cfm and 10cfm which lasted 3 months and 4 months respectively (garbage like the rest of their range IMHO).
Currently on yellow jacket 4 and 6 cfm models which the only downside i can see is the amount of oil they require compared with my old robinair - 24-26oz against 14-16oz - nicely built too with a comfortable handle for carrying

Re: Which vac pump
Hi All,
We also uses Edwards, but i want to know from where i can get the minimum vaccum pressure the pump can achieve with what LPM ?
Also whats the optimum value of Vaccum pressure need to be maintained during production for Low Pressure / Medium Pressure / High Pressure applications
Thanks
Amit
