Products Description
A wheeled, self-contained foam unit for Class B and combined Class A/B fires. Used on its own as a mobile fire appliance, or rolled in as backup support alongside a large fixed foam suppression system.
0.6–1.0 MPa Working pressure
4 / 8 L/s Solution flow
Up to 36 min Effective discharge
OVERVIEW
The portable (lightweight) foam extinguishing unit is built to fight Class B fires and combined Class A/B fires. It can be deployed on its own as a standalone fire protection appliance, or rolled into position as backup support alongside a large fixed foam fire suppression system.
It's mainly suited to oilfield tank farms and refineries, petroleum and chemical plants, oil terminals, aircraft hangars, warehouses, and filling stations - sites where a fast, mobile response matters as much as a permanent installed system.
Mounted on castors for good mobility and flexible handling, the unit connects to a foam gun or foam generator to form a low, medium or high expansion foam fire suppression system on demand.

IN USE
Wheel into position
The unit is pushed by hand on its castors to the fire location, close enough to reach with the hose reel or a fixed monitor line.
01
Connect the water supply
A water line is connected at 0.6–1.0 MPa working pressure, feeding the onboard proportioning system.
02
Foam concentrate is drawn in
Concentrate stored in the onboard tank is proportioned into the water stream, producing foam solution at 4 or 8 L/s.
03
Discharge through gun or generator
Solution is routed through the reel hose to a foam gun or generator, which forms and applies the finished foam blanket.
04
FEATURES
Fully mobile
Castor-mounted chassis lets one or two people reposition the unit quickly across a tank farm or plant yard.
Onboard hose reel
A caged hose reel keeps supply hose protected and ready to unwind straight to the fire ground.
Dual outlet fittings
Integrated valves and couplings feed a hand-held foam gun or a larger foam generator from the same unit.
Standalone or backup
Works as an independent appliance, or as rapid-response backup alongside a site's fixed foam system.

Model code reads as [series] / [tank capacity, L] ([concentrate percentage]) - for example PY8/400 (6%) is the PY8-flow unit with a 400 L tank running 6% concentrate. PQ4 and PQ8 identify the matching foam concentrate tank fitted to the PY4 and PY8 units respectively.
FAQ
Q: How do I read a model code like PY8/400(6%)?
A: PY8 identifies the flow series (8 L/s solution flow), 400 is the onboard foam concentrate tank capacity in litres, and 6% is the concentrate dosing rate the unit is set up for. A PY4 unit is paired with a PQ4 tank and a PY8 unit with a PQ8 tank, sized to match its flow rate.
Q: Why does effective discharge time change with concentrate percentage?
A: A 6% concentrate is used up roughly twice as fast per litre of finished solution as a 3% concentrate, so for the same tank size a 6% setup runs out sooner. That's why the PY8/300(3%) unit is rated for 18 minutes while the PY8/300(6%) unit, with the same 300 L tank, is rated for 10 minutes.
Q: What fires is this unit rated for?
A: It's built for Class B (flammable liquid) fires and combined Class A/B fires, which covers most oil, fuel and chemical fire scenarios at the sites it's designed for - tank farms, refineries, terminals, hangars and filling stations. It is not a substitute for extinguishers rated for other specific fire classes.
Q: Can it run without a fixed foam system on site?
A: Yes. It carries its own foam concentrate and proportioning, so it only needs a water supply at 0.6–1.0 MPa to operate as a standalone appliance. It can equally be brought in as fast-response backup alongside an existing fixed foam suppression system.
Q: What else do I need to complete the system, and how is it maintained?
A: The unit forms foam solution but discharges it through a separate foam gun or foam generator, so one of those needs to be on hand or connected. Routine care centers on checking the concentrate tank and hose reel for leaks or damage, keeping castors and couplings free-moving, and confirming concentrate level and dosing rate before deployment.
