I take it running this accesory kit won't work well with just a standard hand pump? Iv bought a cheap hand pump and it struggles to get over 15 (around 7psi) so I think a vacuum pump would be better and more convenient to run a few at once if I needed to??

Advice thanks

Ok thanks for that, I take it you can adjust the pressure on them all? There not all 1 setting, there's a lot on ebay iv noticed when I searched a/c vacuum pump.

There's a 42litre/min for $125 (weighs 6-7kg)

How does that 42ltr/min convert to the pressure we need? Is 42ltr/min a lot?

Also what the difference between a stage 1 2 and 3??

Can you run a few at once on a vacuum pump then? I'm just thinking if I get one that's too powerful its just going to rip thru all the filters and be no good.
I want to use fast-caps.

A 3 cfm pump will be more than sufficient. It will pull multiple filtering units to the negative vacuum that your looking for. These type of pumps only do one thing, "suck". There's no adjusting vacuum. It will always try to pull -30 in hg.

3 CFM Single-stage Rotary Vane Vacuum Pump R410a R134 Hvac A/c Air Refrigerant:Amazon:Automotive
Just did a quick search on Amazon. You'll still have to buy some fittings and hoses to adapt to your filter top.


Ok thanks for that, how does it work to keep the correct vacuum tho? Won't say 5+ filters need more than 1 filter?

If there's no adjusting then won't more filters drop the vacuum power the more you add??


Also is that not the same as the a/c high vacuum pump ib mensioned? They look the same anyway??

Thanks

buy some whatman fast caps! I just filtered 332 mls of 300mg/ml test E in 5 minutes, NO SHIT! I have a vacuum pump that keeps a steady 25 in/hg pressure, I have never seen gear filter so fast, temp was about 65* C, I have had the filters for a while, this was just the first time I've used on. They say that the filter has a life of 10 L, thats a lotta gear for one filter membrane! They're not cheap, I think they're about 25-30$ a pop, but so worth it!


I used 1 for 300ml was great but soon as I took it off to filter another batch it wouldn't work? Same happened with all 4 that I bought, once it has been vacuumed and took off, once I try to reuse it doesn't work.

If you put the new fastcap on the flask and pump it it doesn't suck on till you add the inlet for the oil.

Once it has oil in the filter if you detach the filter and remove the oil inlet, then vacuum pump it, it will suck to the flask without the oil inlet. It shouldn't do that, that's why it doesn't work if you try and use it a 2nd time.

I don't know why it does that tbh?

Anyone?
