Expander Tank

Fully collapsible self-erecting tank with a floating collar

Product Overview

Our Trident expander tanks are manufactured from PVC as standard (also available in PU).  Expander tanks are fully collapsible and self-erecting without the requirement for any metal frame-work.  The expander tank can be turned inside out for easy cleaning.
