Problem with airflow valve on mini Protank

[doveman]

I recently bought an airflow valve for my mini Protank and it makes a massive difference. No longer does it feel like I'm sucking on a sealed tube and the cloud is much more satisfying. I'd recommend anyone with a mini Protank to get one and they don't cost much. I'm mainly using a Cloupor mini with a SubTank Mini, which is obviously much better but I still like to use the Protank on my Clover spinner as a backup for when that's charging.

The only issue is the airflow valve seems to cause some issues with the connection to the battery and if I do it up normally, it tends to just flash the light when I fire it as if nothing's connected, or sometimes it will light up normally but won't actually power the coil. I have to unscrew it around a quarter of a turn to get it working but as it's no longer tight, it does tend to move from this position and stop working again until I re-adjust it. So I was wondering if there's anything I can do to fix it, so that it works when tightened up normally, as the Protank does without the airflow valve?

Could it be shorting when its snugged up tight?
You could possibly try another head in it see if it solves the issue.

Can you post a PIC of the airflow plz, it sounds like an issue I had, some of the kanger heads are slightly different in size likewise the quality control on the AFC centerpins can be a but questionable.
Depending on what mod you have it might be squashing the 510 on mod causing a short,or it might be a short head missing connection by a smidge.

I'm not sure what you wanted to see or if these will be any good but I took a couple of pictures:





I'm not using it on a mod, just a Clover spinner. I guess it probably is shorting, which is fixed by unscrewing it a bit, although that's not ideal as it makes it loose. The heads do seem to differ in size though, one I've got won't even screw up with the airflow valve, even if I remove the silicone seal, but it does without the normal mini protank screw base.

looks like you can use a screwdriver to mate with the positive pin inside the atty aero base, if so try screwing it in a bit more so its not sticking out so far start with about the same sort of turn you need to currently undo to get it working??

Can't see from the photo what type of coil you are using doveman, is it a BCC (single coil), the old style dual coil or the new style dual coil?

I've used mini Protanks/Aerotanks in the past and would agree with igual, sounds like a short somewhere, I don't think it will be the airflow controller base, sounds more like the coil. It could be shorting out - one of the positive or negative legs may not of been trimmed properly and is touching somewhere, or try pulling out the pin on the bottom of the coil 'very slightly' so it makes contact with the battery better, failing that, change the coil for a new one and see if that sorts out your problem.

these slight difference in sizes do make a big difference, between coil head +ive pins, afc +ive pins and your battery, sometimes playing mix'n'match with heads in the afc make all the difference.... frustrating, yes, but when fractions of a mm make a difference, it has to be done..

Ye definitely like like its shorting out.
Tbh it might be better getting a better tank as I had endless issues with protank mini lol.
If you like the protank style I'd suggest a protank 2 with the additional AFC base from myepack

Thanks, that seems to have helped. It doesn't actually seem to tighten, as I turned it several times it it's still no tighter but it seems like it might have moved it up a bit anyway and it's firing now without me having to loosen the AFC. It might be that the AFC is just slightly shorter than the normal base, so that the head sits closer than it should do.

It's just a BCC but I've got some microcoils as well. A very generous forum member who knows what he's doing recently recoiled and rewicked them for me, so I doubt there's any issues with the coils and it's only when I use the AFC that I have problems, so I think there's just a slight difference in size between that and the normal base that's causing the problem. Anyway, it seems OK now I've turned the pin as phatfil suggested, so I'll try that again if I have the same problem when I change the head.

I'm planning to get a protank 2 actually, just been so happy with my subtank mini that I haven't got round to it yet
