The PRG300 instrument air filter
regulator is designed to provide
clean, accurate air pressure to
instruments, valves, and other
automatic control equipment. This
filter regulator has been proven
to provide accurate operating
characteristics under variable
conditions. Durable materials and a
standard epoxy paint finish provide
long lasting corrosion resistance in
harsh industrial environments.
