M-SERIES FOAM BRANCHPIPES – Medium Expansion

The Delta M-Series range of Medium Expansion Foam Branchpipes have been designed for use with all foam types, producing long throws and coherent flows of stable medium expansion foam over a wide pressure range. The M-Series are strong, compact and lightweight and designed for use in conjunction with Delta Inline Foam Inductors.

Perfectly suited for tackling fire scenarios where rapid foam coverage is essential the M-Series Branchpipes require minimal water for effective fire suppression or blanket coverage of inflammable liquid spills. They are also the perfect choice for use with many of the new hazard material vapour suppression foams. Perfect powerful jets of medium expansion foam are produced, even at low branchpipe inlet pressures. Optimum inlet pressures are between 2 to 7 bar depending on the foam type. The M-Series have a stainless steel body available in a choice of three flow options and can be supplied in either International Orange, High-Viz yellow or Natural finish.

Optional pressure gauge and On/Off ball valves can be supplied for ease of operator control and carrying handles are fitted as standard on all models. Supplied with 2” BSP male threaded inlets the M-Series can accept any International inlet adaptor for compatibility to existing hoselines.

Delta’s M-Series Medium Expansion Foam
Branchpipes are flow engineered to provide three
flow options – 225, 450 or 900 litres per minute to
cater for all types of fire and spill risks.
Fixed, bespoke flow options are also available for
integration into fixed foam suppression systems.

The M-Series are manufactured with a stainless
steel body and mesh net for excellent corrosion
resistance and can be supplied in a choice of
finishes. Available with either black epoxy powdercoated or bronze nozzle holders the M-Series is
incredibly robust and suited for use in any
environments. A wide choice of light alloy or
gunmetal International adaptors are available for
ease of connection to existing equipment.

All Delta M-Series Foam Branchpipes can be
supplied with lever-operated ‘On/Off’ ball valves
as an optional extra. This allows the operator to
have total control over the flow of foam at all
times. Available in Light Alloy or Marine Brass to
suit all climates and applications. A pressure gauge
is also available for accurate monitoring of inlet
pressures.
