Delta Z-Series Variable In-Line Inductors are available in three flow rates to suit customer’s specific application.
Suitable for use with all foam types including fluorine-free foams.




Delta’s Z-Series variable inline inductors introduce foam concentrate into a water stream. They are portable, easy-to-use units with adjustable foam concentration from 1 % to 6 %.
Three flow models (Z225, Z450 and Z900) provide 225, 450 or 900 LPM induction rates. Standard bodies are epoxy-coated aluminium or LG4 gunmetal, while a fully marinised version (stainless steel and LG4 gunmetal) is available for saline-rich environments. Colour options include International, Hi-Viz Yellow or natural metal finishes.
The inductors come with a quick-release foam pickup tube and stainless-steel drum piercer. A twist dial selects 1 %, 3 % or 6 % foam settings. Delta supplies various adaptors so the inductors fit all international hose couplings.
