Description

ZB’s standard- the flow you are used to. Highly responsive feel.

ZB’S open flow- best suited for larger rigs or rigs that require alot of air flow to function properly. These rigs fuction better with more air movement and tend to create more pressure than smaller or lower water volume rigs and thus don’t need as much pressure at the cap and benefit from more air flow. These are also well suited for beginning of a dab where some folks like to move more air.
