Suggested Third-party Components
Note: These are guidelines useful for many installations, but selection of
third-party components is at the discretion of the system installer
or vehicle manufacturer.
Suggested components for CAFS discharges:
The installer must provide fittings and tubing to connect the CAFS components to the
vehicle's discharge outlets. These are
suggested parts for the common discharge sizes. If
the planned discharge system is not covered in this guideline, please contact Pneumax.
Note: Pneumax strongly suggests that every CAFS discharge have an air check valve and
a water check valve, as shown below.
The air check valve prevents foam solution from backflowing into the compressor
and contaminating the oil. The water check valve isolates the discharge, preventing
CAF from backflowing into the foam solution manifold and exiting through another
discharge.

Suggested air hose
The interior diameter (I.D.) of the hose is the most important factor, and any hose with the
correct I.D. and rated to withstand the expected air system pressures (500 PSIG burst
pressure) may be used.
We have found the most cost-effective hose is the push-on type hose. H101 or H201
general-purpose hose has an acceptable working pressure. Gates, Dayco, Parker,
Weatherhead and Aeroquip brands will suffice. All of these hoses come in a variety of
colors for color-coding the lines by purpose.
