Specifications

81 of 104
The air compressor shall be controlled by a modulating inlet valve mounted on the air compressors
inlet port. A controller shall be provided that senses air pressure and controls the delivery volume of
the air compressor while maintaining a constant pressure. The controller shall feature an automatic
balancing system to maintain the air pressure within plus or minus 5% of the discharge pressure of the
fire pump, throughout a pressure range of 60psi to 150psi.
The compressor system shall have operators controls at the pump panel for the following functions.
Automatic pressure regulation, to match the compressor discharge pressure to the pump
discharge pressure.
Fixed pressure regulation, to set the air pressure at on pressure for the use of air tools, etc.
PTO engagement switch
PTO engaged indicator light
AIR TOOL OUTLET Bidder Complies: Yes ( ) No ( )
A 1.00" air outlet supplied by the foam system compressor shall be provided on one of the pump
panels. This outlet shall have a chrome plated 1.0" FNST swivel fitting at the panel and a valve behind
the pump panel. The outlet shall be capable of supplying the capacity of the compressor. A mating
1.0" MNST x 1.0" NPT fitting shall be supplied with loose equipment.
REFILL, SINGLE FOAM TANK Bidder Complies: Yes ( ) No ( )
The foam system's proportioning pump shall be used to fill the Class A foam tank. This shall allow use
of the auxiliary foam pick-up to pump the foam from pails or a drum on the ground into the foam
tank. A foam shut-off switch shall be installed in the fill dome of the tank to shut the system down
when the tank is full. The fill operation shall be controlled by a mode in the foam system controller
stating TANK FILL. While the proportioner pump is filling the tank, the controller shall display FILL
TANK. When the tank is full, as determined by the float switch in the tank dome, the pump shall stop
and the controller shall display TANK FULL.
AUXILIARY AIR OUTLET Bidder Complies: Yes ( ) No ( )
One (1) air outlet shall be supplied by the compressor for the CAFS. The outlet shall provide air to an
air reel for tool usage. An adjustable regulator and gauge shall be provided near the reel for pressure
regulation with a moisture separator. When the compressed air foam system is used the performance
shall be reduced if the air outlets are in use at the same time. An oiler shall be provided as a part of
the system to provide lubricant to air tools attached to the air reel.
CAFS CONTROL Bidder Complies: Yes ( ) No ( )
A second air injection switch shall be provided for the turret in the cab.
CAFS CONTROL Bidder Complies: Yes ( ) No ( )
One (1) air injection locking rocker switch shall be provided in the cab for the turret.
COMPRESSOR COVER OVER PUMP Bidder Complies: Yes ( ) No ( )
The CAFS compressor shall be totally enclosed with a cover constructed of .125" bright aluminum
treadplate. The cover shall be provided with adequate ventilation (louvers or knock outs as required
for the specific compressor) and have any necessary access doors for maintenance or operation. The
cover shall be removable.
FOAM SYSTEM TRAINING Bidder Complies: Yes ( ) No ( )
The fire department shall order one (1) vehicle with this foam system. The operation of the foam
system shall be demonstrated at the plant where the apparatus was manufactured.
This demonstration shall include:
- A review of the foam system manual, emphasizing key areas
