The B2 Injector is an addition to our line of "B" Series heads, it can still be filled with balls but in an injector style diffuser which opens the door to be able to use your flowerpot with an array of widely available glass bowls.
The diffuser is a "B" style diffuser, so it can be filled with balls which increases the surface area the air must travel through before it hits your bowl.
The 3/4" screen will sit in a groove where it will retain all the heating balls.
The size of the injector is based around our 18mm post, which will allow for it to work with a wide variety of bowls already available on the market.
Some examples of available bowls that work:

These are just a few examples, but the possibilities are endless!
