The product: The Radiator 22mm MTL RTA is a Chinese-original design (by Benzene Ring Company, manufactured by Auguse) that made waves in 2023 for its innovative airflow system. At 22mm diameter and 4ml capacity, it’s a compact top-airflow MTL RTA with a unique twist - the air enters through the top cap but is redirected to hit the coil sideways, achieving the flavor concentration of a bottom-airflow atty without the leaking risk.

What our customer says:
“the mtl airpins are incredible silent, impossible to make it wistle even after longer use and different vape styles(mtl/rdl). wicking works great aswell, building it is very easy. sadly the refilling is not simple, you have to unscrew inner air pipe first, otherwise it will block tank. if you force the tank it, you will strip the inner thread because of different threadpitch. rta arrived cleaned and is machined very well, i dont like the engraved radiator text at the vaporchamber though.”
Pros:
[OK] Genuinely silent airflow - no whistle at any setting. This is rare in MTL RTAs
[OK] Excellent flavor clarity - the top->side redirect creates a turbulent airflow that amplifies subtle notes without overheating
[OK] Wide air pin selection - 6 pin sizes (0.8->1.6mm) + block pin, covering tight MTL to loose RDL
[OK] Easy build - dual posts with adequate spacing, straightforward wicking
[OK] Well-machined - clean threads, arrived pre-cleaned
Cons:
Outdated refilling - requires unscrewing the inner air pipe; force it and you’ll strip threads
Capacity less than advertised - the wide chimney eats into the 4ml; expect ~3.5ml usable
Engraved “Radiator” text on the vapor chamber may divide opinions aesthetically
Build quality is decent, not premium - machining is good but doesn’t rival higher-end German or US-made attys
A well-engineered MTL RTA with a genuinely innovative airflow system that delivers on flavor and silence. The refilling hassle is the main trade-off. Best for vapers who prioritize flavor and build quality over convenience.
