The bottom coil DBOX PuriTank is made of solid metal and glass and holds a massive 4.0ml of e-liquid so frequent refills are not required.

Since the DBOX PuriTank is perfect for use with abrasive liquids such as the cinnamon red hots and spearment flavored e-liquids that often cause problems by reacting with the plastics used in standard clearomizers.

Also, the bottom feed design makes the PuriTank great for use with thicker liquids.  Since gravity helps keep the wick saturated thicker liquids (higher VG content) can be used without getting the dreaded dry/burnt hits that are common with many tanks.

Replacement Coil Heads for this product can be found here:  DBOX PuriTank Replacement Heads (5pk)

Fits any 510 or eGo threaded battery.  (Not recommended for use with mini/cigarette sized 510 batteries)

What You get With the Kanger ProTank Kit:

• 1 x 4.0ml PuriTank with clear pyrex glass tank.
• 1 x 1.8ohm head and wick assembly
• 1 x 2.2ohm head and wick assembly
• 1 x Stainless Steel Calabash style drip tip
• Instruction card

How to Use your DBOX PuriTank:

• To fill, turn the tank upside down and remove the threaded end cap.  Fill the outer portion of the tank (avoid getting e-liquid into the center airflow tube).  Screw the head and wick assembly onto the threaded end cap tightly then screw the end cap onto the tank tightly.  You can now turn it rightside up and check for leaks before using.
• Gurgling or Leaking can occur if liquid gets into the center airflow tube.  To clear this liquid and improve performance remove the tank from the battery and blow through the mouthpiece into a paper towel.  The excess liquid will come out of the threaded end of the device.  If this happens often you may need to check that all connections are screwed down tightly or replace the head and wick assembly with a new one.
• The head and wick assembly will sometimes loosen itself when the threaed end cap is unscrewed.  Always check that it is screwed on tightly before replacing the threaded end cap.  Not doing so could result in a leaking or non-working device.
• You should never run the tank completely dry.  Doing so could result in a burnt or damaged wick and can cause leaking.  Refill the tank when the liquid level reaches approximately 1/3 full
• The lifespan of replacement heads can vary quite a bit, but following the above instructions will maximize the lifespan of the coil.
