Delta Marinised Z-Series Variable In-Line Foam Inductors are designed for continuous use with sea water in harsh, saline-rich off-shore environments providing effective resistance to corrosion and long-term durability.




The Marinised Z‑Series foam inductors from Delta Fire are specially engineered for continuous use in harsh, saline‑rich marine and offshore environments that can quickly corrode standard equipment. Unlike the standard Z‑Series inductors, the Marinised version is manufactured with a corrosion‑resistant gunmetal body and stainless steel nozzle and filter, providing enhanced durability and long‑term resistance to salt water and corrosive atmospheres. It still offers fully variable foam induction between 1 % and 6 % and is suitable for all foam types, including fluorine‑free foams, while maintaining compatibility with international hose fittings. This makes the Marinised Z‑Series ideal for marine, offshore, industrial and other demanding sectors where exposure to seawater and extreme conditions is expected.
Marinised Z‑Series foam inductors are typically used in environments where exposure to salt water, corrosive atmospheres, or harsh weather conditions is expected. Common applications include offshore oil and gas platforms, ships, marine terminals, harbours, and coastal industrial facilities. They are also used in industrial and chemical sites where corrosion resistance is critical. The marinised design ensures long-term durability, reliable foam induction, and minimal maintenance even in the most challenging marine and offshore conditions.
Yes. Marinised Z‑Series foam inductors provide the same flow rate options as the standard Z‑Series. Both versions are available in models with induction capacities typically around 225 LPM, 450 LPM and 900 LPM, allowing foam concentrate to be drawn into the water stream at the same performance levels. The only difference is that the marinised version uses corrosion‑resistant materials for continuous use in harsh offshore or saline environments, while still offering the same fully variable 1 % to 6 % foam induction and flow capacities as the standard models.

Fantastic equipment and customer service. Would high recommend Delta Fire to any company looking for fire service equipment. After doing a lot of market research, I found and contacted Delta Fire to get more information about their equipment. Any questions I had where answered, they helped me look at my company's needs and pick which products where best suited. Extremely helpful. To add the very long warranty and that they are UK made is what separates the from the rest. Thank you guys for all your help. 10/10
