NOTE
These are general recommendations. Due to variations in viscosities of
catalyst and resin (Gel-Coat), actual optimal sizing may differ. The intent
is to optimize mix by minimizing catalyst pressure.
NOTE
Periodic lubrication of the chopper air valve assembly is
necessary to ensure smooth operation.
The OLD style chopper air valve assembly (102-2618) is
no longer supported by Binks. Contact Binks to obtain the
NEW style chopper air valve assembly.
