Airflow estimates

[vaper1960]

I've been doing lots of research about RTAs (specifically MTL, but I like "loose" draw) I was wondering if you all can help with a way to compare airflow of different tanks. Even if you don't know exactly the dimensions of the airflow, try to estimate (or compare to other tanks) 1mm, 2mm, 3mm, ect. Here's a list I made from another thread... very interested in feedback on these (or others, including DTL):

GEEK VAPE AMMIT 24MM MTL RTA

Coppervape Hussar Project X Styled RTA

INNOKIN ARES 24MM MTL RTA

Fumytech Rose MTL RTA

CTHULHU MOD HASTUR MTL RTA MINI

EHPRO True MTL RTA

Berserker V1.5 Styled MTL RTA

COILART SALT 18MM RTA

ULTON Tripod Style 316SS 22mm RTA

SILVERPLAY 24MM MULTI AIRFLOW RTA

SXK Doggystyle Styled RTA

and maybe the kayfun lite 2019...

From what I gather online.

1.6mm air-hole on deck for SXK Doggystyle, SJMY has a 2.3mm one.

Earlier version of the Fumytech Rose (I think black with red) is 1.8mm, black and gold version is 2mm.

Berserker Mini deck-hole is 1.4mm.

AngeNZ, thank you so much! That was exactly what I hoped for. Example: Berserker 1.5 "teenytiny" I love that RTA but no way for me... too restricted for sure! I actually meant to say "maximum airflow" cause that's a make or break for me. Just guessing, but I would say I need at least 2.5 mm (my Innokin Prism S tank has 2 small holes... nice little tank, like the coils, but totally not enough airflow. I had to drill out one hole with a 1/16" bit to make it usable) Another example: I have an Aspire Nautlius X tank and use it between half and wide open (slots on both sides... hard to judge mm)

 

[vaper1960]

I was very excited about the Ehpro True but don't know if 1.5 mm is going to do it... too bad (Silverplay is looking good right now!)
Looks like I should have said "loose MTL to restricted DTL".

2.5mm - 3mm is my favourite airflow bracket - but I mtl them

What is SMJY?

I'm looking for the same as you just to put back though. Kayfun 5 is 3.2 I think? Kayfun Lite 2019 is 1.8.

It's a Chinese company like SXK that make clones:

If interested in a kayfun, it's going to be the k5 or squared, as all others might be to tight for you...

Thought I'd bring this thread back to life... How about the SteamCrave Glaz mini RTA? It looks so simple to build and wick and should be fairly leakproof. I need an RTA to carry around.

 

[vaper1960]

I found the answer in a review... kinda bummed. Largest airflow hole is 1.6 mm (many will like this but not enough for me)

 

[AngeNZ]

What about the OFRF Gear RTA 2ml/3.5ml? Compact and incredible flavour. It's restricted lung, but could be tightened down to a very very airy mtl

 

[vaper1960]

My choices (besides the two Silverplays I already have (one for loose MTL. one for restricted DL) are:
Project X and Tripod (clones)

 

[vaper1960]

What about the OFRF Gear RTA

Ok, I missed that one... nice! Really good airflow and bubble option for more juice. Seems like it would have very concentrated flavor. Decent price (and that's from the US)

 

[vaper1960]

Off topic, but first I want to get a Vapefly Galaxies MTL RDTA. I am very excited about that but technically it's not a RTA so hadn't mentioned it.

 

[vaper1960]

So I have another one... Digiflavor Siren 2. Also found a clone. I love the airflow on this and easy build deck. Anyone tried the clone? Might sport for the real thin on this one. Does it leak (I know any RTA can depending on wicking)

 

[vaper1960]

I didn't realize this one has optional airflow inserts that are larger:
Coppervape Dvarw MTL Styled RTA
As high as 2.5 mm airflow (you get a set of different ones)

It's an older RTA. And some people here had problems with it leaking. There are a lot of much better RTAs out now.

Hellvape MD MTL RTA would be a good choice. Plenty of airflow options:
