Delta Monitor Canons are available in six standard flow rates but can be flow engineered to suit customer’s specific requirements on request to suit any water or foam application. The Delta Canons offer excellent performance characteristics enabling projection over long distances and are available in DFC-A (light alloy) or DFC-M (stainless steel) models in either Standard or Self-Inducing formats. The DFC-M Series can also be supplied fitted with a lever-operated ‘Blabber-Mouth’ foam spreader which flattens and widens the foam stream providing rapid blanketing of inflammable liquid spills. When the spreader function is disengaged the unit will provide the same performance as the standard canon. With flow options from 1500 LPM (396 GPM) to 4000 LPM (1056 GPM) and throw ranges from 30 metres to an impressive 73 metres the Delta Monitor Canon range provides enhanced risk protection when used in conjunction with Delta Fire Monitors (or equivalent). The Delta Monitor Canons are suited for use with both Fixed & some Portable Monitors. Please contact us for advice on compatibility. Supplied as standard with 2½” BSP female threaded inlets.

FAQs

Delta Fire Standard Monitor Canons, often referred to as “Blabber Mouth” monitors, are high capacity firefighting monitors designed for delivering large volumes of water or foam over long distances. They are used in industrial, marine, and petrochemical environments where powerful, fixed or portable fire suppression is required. They provide a simple, robust, and highly effective solution for major incident fire control.

The term “Blabber Mouth” comes from the large bore discharge design of the monitor, which produces a very wide and powerful stream of water or foam. This high output flow creates a visually distinctive, heavy discharge pattern that led to the informal industry nickname over time.

Its effectiveness comes from its high flow capability, simple mechanical design, and long range projection. It delivers large volumes of water or foam with strong reach and penetration, making it suitable for cooling, fire knockdown, and protective water curtains. The robust construction also ensures reliable operation in demanding industrial and marine environments where durability and performance are critical.
