The CET Wild CAFS provides a self-contained, diesel-powered, “slide-in” type compressed air foam system (CAFS) unit. The CAFS unit is designed to fit into the back of a standard length and width pick-up truck body.
The CAFS is designed to discharge water only, air only or compressed air foam from the same discharge outlet. In addition, the consistency of the compressed air foam (expansion ratio), wet/dry is fully adjustable. There is also a water only discharge that will supply two spray nozzles to protect the truck.
Part #223510105
The power to drive the system is provided by a Kubota V-1505T, 4-cylinder, 4-cycle, water-cooled diesel engine at a rating of 45HP @ 3000 RPM. Automotive engines or ratings will not be used. The power unit has a 35-amp alternator, a dry cartridge air filter and a muffler.
Water Pump
The water pump is a CET model MR single-stage centrifugal pump with a vertically split aluminum case with replaceable bronze impeller and seal rings on a stainless steel shaft. It is designed to provide up to 275 GPM of plain water flow and pressured up to 250 PSI with the air compressor in the “unload” mode or “load mode”. The pump seal is of a mechanical design.
Air Compressor
The air compressor is of the oil injected screw type, designed and installed to supply a minimum of 80 CFM at 125 PSI of air at maximum engine RPM. The air compressor is driven by two dry Goodyear -V type belts from the engine crankshaft and is mounted to the pump platform. The air compressor is capable of maintaining prolonged pressure from 100 to 150 pounds per square inch throughout the service life of the complete CAFS unit.
The compressor is cooled with air and the compressed air is cool enough to be utilized by any tooling. The system is be capable of maintaining recommended operating temperatures throughout the full operational range in ambient temperatures up to 115°F. A dry cartridge type air filter is provided on the compressor air intake.
Foam Proportioner
The foam proportioner is a Foampro model 1601 automatic, 12-volt, direct-injection system capable of maintaining a solution ratio of as low as 0.1% to at least 1% of class “A” foam. The proportioner has a maximum operating flow range of 3-145 GPM (11-549 liters per minute) and a maximum accuracy flow range of 5-110 GPM (19-416 liters per minute). The proportioner is capable of using different types of class “A” liquid foam concentrates. This complete system is mounted within the module
Drive System
The water pump is driven using two V-type belts with automatic. The compressor, which is mounted to the engine flywheel housing, is belt-driven using a two V-type belts with automatic tensioner.
Electrical System
All electrical equipment installed by the manufacturer is in conformance with current automotive electrical system standards and the requirements of the applicable NFPA apparatus standards. The wiring is individually and permanently color and function coded.
All exposed wiring runs in loom with a minimum of 280°F (137.8°C) rating. All wiring loom is properly supported and attached to frame members along the entire rum. At any point where wire or looms must pass through metal, rubber grommets are installed to protect the wire from abrasion.
The main low voltage electrical terminal block and circuit breaker panel are provided behind the pump operator’s panel in a location which provides easy service access.
The electrical connections are made using heat shrink and/or waterproof connectors. All electrical circuits are protected with automatic reset circuit breakers or fuses.
Priming System
A CET Ventury type priming system is utilized. The primer is capable of priming the water pump through 20' of hard suction hose with a 15' lift. Primer controls is mounted on the operator’s panel.
Plumbing, Hoses and Lines
All piping is stainless steel. Use of grooved end pipe couplings are required for flexibility and movement of system components on mobile equipment. The compressor hoses are made of Teflon and
braided with stainless steel. Hydraulic hoses are not used. Check valves are required throughout the system to maintain integrity and shall be placed so that the air, water foam and foam solution do not inadvertently mix. One (1) master drain valve is provided on the control panel to completely drain the system to prevent freeze damage.
Tank to Pump
There is a 2.5" tank to pump suction valve fitted in the module and controlled from the operator’s panel with a push/pull T-handle control.
Inlets
A 2.5" inlet is provided to draw water from the control panel with a 2.5” NH male connection and cap is provided. It is possible to use that line for “direct tank fill” operations with a pressurized water source.
Discharge Outlets
There are two 1.5" discharges with stainless steel, plumbing to panel, mounted CAF discharge outlet. Two additional CAF discharges are plumbed to the rear of the module for use as a hose reel and pre-connect.
Check valves are installed on each discharge to prevent foam from back flowing into the pump. Discharge valves are
Fire grade self-locking, swing-out valves.
Tank Refill
A 1" tank refill line with a 1" Akron and flexible, reinforced hose using internally expanded fittings to allow maximum flow.
Module Frame
The frame is constructed of steel and designed for rigorous fire service. The top of the module is an aluminum diamond-plate material, with slide out louvers for a complete service access door.
Control Panel
A brushed stainless steel, laser-cut control panel is mounted to the electrical box, which is of a water resistant design. The following items are marked in a logical manner on the control panel to provide for simple and easy operation.
- 2-Lamp Shielded Pump Panel Light Cluster & Switch
- Water Tank Level Indicator

Testing
The competed unit shall undergo a manufacturer’s run-in test prior to delivery. The engine, pump and air compressor are operated for a minimum period of one day, during which time the test operator will monitor and record the functions and performance of each system component. Compressed air foam is produced during the test.
This testing will be performed to ensure proper system operation and performance prior to shipment. The manufacturer provides written certifications that the tested unit meets all performance criteria contained herein (NFPA). Water flow performance is measured using standard fire department test methods.
Manuals
One (1) copy of the Operation and Maintenance Manual and a CD copy are provided to the purchaser with each unit. This manual includes detailed instructions in the operation and maintenance of the overall unit, engine, water pump, air compressor and foam proportioner.
