Axminster NVD750-2 Numatic dust extractor

HOME

---

I finally got a dust extractor for the workshop.
My Hoover would not filter out any fine dust and so things were becoming unhealthy.
I'll be doing some wood turning in the lathe and some routing soon (all indoors) and a dust extractor is now a must have item.
I bit the bullet and spent 310 pounds.

↓ I opted for the Numatic NVD-750-2.
I bought the machine from Axminster in High Wycombe. It has the Axminster colors, but it is a genuine Numatic. I'm getting to like the Axminster white.
It is a nice light compact unit and I can move it about the house easily. This is a big plus for me as I sometimes cut large wood sheets in the kitchen and will need to use it down there.
The vacuum is not quiet. It is fairly noisy but it is not so noisy that it is a great irritation. It is just as noisy as a normal house vacuum.
I can hear the vacuum running from every room in the house.
I can only just barely hear the vacuum when standing outside the house in the garden. I'm sure it will not bother the neighbours when I run it for long periods.
With 2kw of power consumption the machine gets very hot.
It will suck your eye out. I've already lost a heavy screwdriver up the hose and I will have to go digging in the bag later for that.
It does a great job of keeping the workshop clean and collecting dust from power tools.
The 3 stage filtration system means the exhaust air is virtually dust free.
I am extremely pleased with the machine.

It comes with:
Twin 1200w motors
4m x 100mm hose
2.9m x 32mm hose and step down adapter
5 filtered bags
An extra filter bag that is already cut in half (for use in wood chip mode).
1st stage round red filter
2nd stage round white filter
A nice long sturdy power lead
2 year guarantee

↓ The NVD will sit to the left of the lathe.
It is vulnerable there and it will get covered in oil and swarf and things will get dropped on and around it.
I decided the best thing to do would be to make a housing for it.
The housing will protect the NVD and also muffle down some of the noise.
When necessary I will be able to quickly dismantle the housing and move the NVD out.

 

 

Here is the space to the left of the lathe.

 

The homemade carcass is moved into position.
I decorated the back bedroom recently and disposed of an old bed and also removed the previous owners chipboard shelving.
I recycled, and used the chipboard and the wood from the bed to make the housing.
The slot for the electric cable is at the top left.

 

The NVD is lifted inside the carcass.

 

The front piece of the housing is secured with wing nuts.

 

The top back piece is secured with wing nuts.

 

The top front piece is secured by press fitting it onto a couple of 3mm metal studs.

 

The housing is pushed back into position.
The 32mm hose is connected to the NVD.
The hose will reach everything in the room from there.

 

The 32mm hose tucks away very nicely.
I have also gained a little bit of workspace on top of the vacuum housing.
The little filler piece on top and at the front of the housing can be easily removed to ventilate the NVD if it gets too hot.

 

After a few hours use I found the Numatic nozzle was getting battered and worn. I made a sacrificial nozzle out of 38mm plastic waste pipe.
