OK but wouldn't fit ...

The height of these just wasn't enough to enter & locate in my existing system ( based on standard soil pipe fittings with each of the blastgates sandwiched between two 110mm WC pan connectors ) . The actual item itself wasn't well finished and had some sharp edges to the two halves of the casting both internally & externally . The movable gate also seemed to be a bit sloppy but does have the option of the locking screw . All in all I'll be sticking with the cheap & nasty plastic ones ...

excellent and very good value

I had a setup based on the axminster plastic gates that I found to be flimsy and not air tight. These aluminium ones are a very solid, quality product that seems to be air tight so far at least. I suggest to fit the thing so that the 100mm pipe is vertical and avoid the blocking plate dropping downwards with gravity... if not locked with the screw, which I usually do not bother with (i.e. I leave it loose). My setup now uses just two pipes that go to one 100mm pipe via a Y bend. I have 3 metres of very flexible 100mm diameter antistatic pipe connected that I manually connect to three machines as needed because I tend to use one machine for several hours and then move to the other machines. I have taken care to use metal duct in the pipe layout under the machines and these are earthed to avoid a fire if ordinary plastic drain pipes are used. The system works well.

I researched blast gates here in France and a similar product exists here in bent stainless but it is not as good and costs £30 each. I also looked at 125mm gates with an electric control and pneumatic actuator and these cost about £400. I looked at DIY approaches on Youtube etc and these looked to me as flimsy, not robust and would take hours to fabricate.....so these aluminium ones fit the bill very well.

I agree with other reviewers that you need to use tape or a heavy duty glue / mastic to prevent leaks. My local pro shop says that dust extraction is the most complex thing in woodworking as like me most people have a small size extractor (900m/hr) due to cost, physical space and noise constraints associated with a bigger machine. The trick seems to be to have as short a duct run to the machine and completely air tight blast gates which these give you.

I highly recommend

Just what I needed, just when I needed them!

Just bought (amongst some other bits and pieces) a couple of alloy blast gates for my 4" dust extractor system. I had the plastic ones before, but they seemed to clog easily and required constant digging out of the grooves with a bent paper clip - if I didn't do that, the blast gates wouldn't close properly and I lost suction. The alloy ones open and shut smoothly and there's even a threaded bolt which holds them in place and avoids the gates sliding in or out of their own accord. The only downside seems to be the rather short fitting flanges - mind you, that was soon sorted out with the addition of a length of duct tape. All in all great improvement over the plastic ones!

Excellent!

Agree on closing the gap with tape, but they exist for a reason wich is no clogging, so once and a while you´ll have to take the tape of and unclogg.
Regardless that wich isn´t really a problem with a powerfull dust extractor, they are great!!
Recently created a dust extraction system with 9 meter of tube, 10 100mm of these blast gates connected to an 950m3 dust collector, and works perfect!
Dont forget to mount them in the right position.

Good quality

I agree with Mr. Esbjorn and also Alan.

The plastic blast gates can get easily clogged from chips and it's not easy to remove them. The aluminum one has this quite large opening at the back which needs to be closed.

The problem I've found is that these blast gates fit loose in the plastic connectors from axminster. I had to put 4xM4 screws but now works like a charm.

A really good improvement!!!
