The FRL-15 is a combination air filter/regulator/lubricator
unit that controls the air pressure to the chuck's
built-in cylinder, and provides lubrication
to the rotary air bearing assembly. This unit
also filters contaminants from the air supply.
Water that accumulates in the filter unit can
be purged by a manual drain.
Each unit includes a pressure
gage, as well as air hoses and fittings.
