help a little

HI
Thanks for all your advice on buying a dust extractor, I eventually bought a numatic nvd750 extractor, but I don't know if it's working right when I use the 4" hose it barely removes the comb webs off the rafters, it just will not pick up dust off my bench ethier, the defuser seems to be generating more air than the hose. the good news is I only bought it 7 days ago, the bad news is I cut the hose up to filter different machines with a y joint, the suction is crap with just a single 4 "hose connected, does anyone know of my rights of return of this item, and it's noisy as hell too.
I know I should have checked the suction before cutting the hose, but in my favour it does say trade on the side of the bloody thing.
cheers

Mine sucks like anything, definitely send it back. Do remember its not airflow but pressure with these.

The noise is normal, either live with it or build a noise reduction cabinet.
The suction should work. Check you have the connections right. When you cut the hose did anything fall inside and get stuck?
Take out any bag inside to see if that improves it. If so do you have the wrong bag?

I have the same extractor and it works very well indeed. Silly question, but you have opened the exhaust haven't you?

Yeah I have opened the fitting on the top of the extractor,
I want to use the extractor with a hood connected to the 4" hose, should there be enough suction to do this ?
I have spoken to rep from axminster and he said it operates on a vacuum

if this is the case then it's not fit for purpose, what's my chances of getting my money, considering I have cut the hose?
cheers all.

Remove all hose, bags/filters, and see what the suction is like. Easy way to narrow it down.

HI
It's a little late, I have packed it all up to go back, It's not really working out of the box?
just one question is this extractor ok to use in a system of machines?
I've bought fittings and blast gates for a system?
thanks for all of your help.

I've no experience with that machine per se, but the flow rate of 300m^3/hour on the Axminster site seems woefully underpowered for a system of HVLP requirements.

The end result is I returned the extractor, and instead of refunding like I agreed over the phone with one of Axminster tools reps, they sent it to a engineer to look at it, and he concluded, after a hour of inspection that I had left the defuser cap on the top of the extractor head, which I did NOT ,after all I did read the instruction which came with the damn thing, so by the time I had to respond to them they had already sent it back to me without any formal conversation at all, the bottom line if I wanted to return it I would have to pay for the engineer's inspection which is 10 percent of the total cost which amounts of 50 quid , So I have decided to keep the thing, not through choice.
SO MY ADVICE IS STAY WELL AWAY FROM AXMINSTER TOOLS !!
