Pressure tank
Assy: AT7-0012-CB

Product information:

Absorbs unwanted pressure changes and normalizes the workflow of the whole water system. 


It works by encapsulating an air bubble under consistent pressure within a flexible membrane. The air bubble's pressure is pre-set to 1.4 bar and can be adjusted using a bicycle pump.


We recommend using it with all AUTOTERM combiBOIL models that use our Pressure Pumps (Assy: AT7-0010-CB).
