FreeMax Mesh Pro Tank is a 25mm diameter sub-ohm tank which features dual and triple mesh coils. Constructed by stainless steel and pyrex glass, it has a juice capacity of a decent 4ml (5mL for optional e-Juice capacity) and is conveniently refilled by removal of the top cap. Airflow can be set at the bottom and occurs via two adjustable air slots that can even be set to all the way closed. Knurling can be found throughout this device making adjustments of the airflow a breeze. What’s the important, the Mesh Pro Tank works with dual and triple mesh coils that really bring out flavor thanks to a larger coil contact surface area. This design allows more even vaporization of juices and absorbs e-liquid more easily. 5 colors are available.
