LOW PRESSURE STRAINER

A low pressure foam concentrate strainer is mounted  at the inlet of the foam pump. The strainer protects  the pump from
debris that might accumulate in the  foam concentrate tank. The strainer/valve assembly  has a composite non-metallic
housing with stainless  steel mesh strainer element and includes a service  shut-off valve.

The valve inlet offers 1/2-in NPT (13 mm) threads, with a fitting to connect a 1/2-in (13 mm) ID foam concentrate suction
hose.

The strainer and valve are low pressure devices and are designed for installations where the strainer IS NOT subject to
HIGH pressure flushing water.

HIGH PRESSURE STRAINERS (FS Series)

Hale FS series strainers (FS15 and FS25) are panel mounted with a 500 PSIG (34 BAR) pressure rating, suitable for use
where flushing water pressure must pass through the strainer.

The FS15 strainer uses 3/4” (19 mm) NPT connection ports and a 1-1/2-in NST cap. It is suitable for use with Class “A”
and low viscosity Class “B” foam concentrates.

The FS25 strainer uses 1” (25 mm) NPT connection ports and a 2-1/2-in NST cap. It is suitable for use with both Class “A”
and Class “B” foam concentrates.

TANK SELECTOR VALVES

SmartFOAM models 3.3, 5.0, and 6.5 may use dual foam tanks for A and B foam concentrates. Selection of the desired
foam concentrate tank with the

ADT

panel mounted toggle switch or

MDT II

selector automatically changes the foam con-

centrate injection rate to the preset default rate for the selected foam tank. No further operator Intervention is required.

The

ADT

MDT II

and

MST

include the check valves and connection points to provide foam pump flushing capabilities.

Air Dual Tank Selector (ADT)

The Air Dual Tank (ADT) valve is an air operated foam tank selector valve that enables selection of foam concentrate de-
pendent on fire ground operational demands.

The ADT is an integral part of the foam pump and provides an electrical interlock for the low tank level sensors and con-
centrate injection rate. A panel mounted selector toggle switch with indicator lights controls foam concentrate tank selec-
tion and shows which foam concentrate tank is in use.

Manual Dual Tank Selector (MDT II)

The Manual Dual Tank (MDT II) selector valve is available for the Hale Foam systems with dual tanks. The MDT II is a
panel mounted, manually operated selector that provides selection of foam concentrate dependent on fire ground opera-
tional demands.
