Mason Dump Tank 40mm by Vapergate

Time for another hardware review here at the Belfast Vape Bar. This time we have something rather large – 40mm, to be precise. Massive! Today we are reviewing the 40mm variant Mason ‘Dump Tank’ RTA by Vapergate. The Mason was sent to us by Vapergate themselves so that we could get a review up for you all before these go on public sale on the 21st August. So let’s get down to business and have a look.

Having a quick look over the packaging, Vapergate have gone with their good old, brick look. Although this time, in white – as the Mason normally comes in a black box. Flipping it over, you can see all of the specs and relevant information too.


  • 30mm Build Deck
  • 3mm Post Holes
  • 17ml Juice Capacity

Opening up the box, I’m greeted by the monstrosity that is the stainless steel Dump Tank. Along with the drip tip and spare glass, it’s all bundled up in padding layered with a nice, standout red felt. I have to say that the guys at Vapergate definitely know how to make their equipment stand out.

So let’s grab this Dump Tank and have a look over it. The first thing that is immediately noticeable is that this is a very heavy piece of kit. Scanning over it, all I can think is that it’s a piece of beautifully-machined excellence. I’m going to take it apart and we can look at the inside.

So as per usual we screw the top off and the build chamber barrel comes off and… holy build-deck batman. This thing has a 30mm, 2-post build deck, like the Mason Gemini. But with a 30mm deck, this means it’s time to build. Let’s have a look and see what I can do with this bad boy.

So for this, I’m going to use a DNA 200 along with some 20 awg Mad Rabbit, low-resistance wire – just to see how much fun I can have and to make sure that it chucks clouds for days. I’m going to wrap the coils around a 5mm bit, just so that I can get loads of cotton into the build to try and prevent leaking.

In the end, I went with 8 wraps and it lights up perfectly. I’m using the good old Cotton Bacon today. Although it’s already my go-to generally, Cotton Bacon has an affiliation with Vapergate themselves – so when you purchase a Mason, you’ll get a small packet with it.

One thing I’ve liked about the Mason series is the massive airflow. This monster is airflow city. If I’m honest, I’m just going to hit this at 150 watts in the hopes of not getting a dry hit. Although in saying that, it’s juiced up well – so all will hopefully be OK. With a DNA, it’s just all ‘go’ with no ramp up and no home – it’s incredible. At 150 watts, you’d obviously expect a seriously warm hit, but with all of the airflow you wouldn’t even notice.

So sod it, let’s try the full 200 watts…… Easy. The airflow on this makes vaping at extreme wattages like a casual walk in the park.

All in all, this is 100% a must buy if you can get over the sheer size of it. I’ll more than likely whip one of these out in any of my upcoming competitions.


  • Large juice capacity
  • Solid construction
  • Aesthetically pleasing
  • Easy to build and wick


  • Drip tip restricts airflow
  • Hex screws would have been preferred
