DeVilbiss FRC-650 Manual Del Usuario página 3

The DeVilbiss FRC-650 is a compact piece of equipment which
brings together a pre-filter, coalescing filter and air regulator in a
single unit. To ensure high level performance for many years, it is
important to carefully follow the instructions in this manual.

PURPOSE
The purpose of the DeVilbiss FRC-650 is to remove humidity, oil
and solid particles which exist in compressed air and provide
clean, dry, regulated air.
IMPORtANt
It should never be used under conditions that exceed the specified
pressure and temperature.
It should never be used in air systems destined for human
breathing, nor in gas systems which are not inert.
OPERAtION
Air enters the FRC-650 and is centrifuged by a deflector (19),
which impels the liquid and solid particles to the walls of the
bowl (29), where they trickle and accumulate at the bottom of the
bowl, and will be periodically removed via the drain (25) located
on the right. Then the air must travel through the pre-filter (21),
which retains the remaining residues. Finally, the air goes to the
coalescing element (22). The liquids condensed between the pre-
filter and the coalescing element trickle down and accumulate in
the reservoir (27), and will be periodically removed via the drain
(26) located on the left. The clean and dry air goes to the regulating
valve that is controlled by the regulating knob (1).

Automatic
The regulator is self relieving, and when it is necessary to lower
the regulating outlet pressure, the relief device automatically
relieves air pressure so that the air is regulated to the new set
pressure indicated on the gauge (10).
In addition to allowing for easy regulation to any pressure, the
regulating knob is robust and solvent resistant.
The gauge located on the bowl (28) indicates the air pressure
available at the outlet identified as "line".
INStALLAtION
The DeVilbiss FRC-650 should be installed in a vertical position at
the downwards end of the line, using a coupling and a valve to
shut the air flow at the time of maintenance.
It should be installed close to the point of usage in a place of easy
access to facilitate regulating, drainage and maintenance.
Do not install the DeVilbiss FRC-650 in areas above equipment.
Drained water may cause damage to the equipment.
REGULAtING OPERAtION
After installing the DeVilbiss FRC-650, and before opening any of
the ball valves, turn the regulating knob counter-clockwise so as
to completely stop the flow of air.
Open the desired ball valve, and turn the regulating knob clockwise
until you reach the desired outlet pressure.
When a new pressure is necessary, reach it from a pressure below
the one required.
MAINtENANCE
Disassembly of the regulator
Before disassembly, close the air supply and turn the regulating
knob (1), completely counter-clockwise so as to relieve the spring
pressure (5).
• Remove the screws (2) from the flange (3) and remove
the knob assembly.
• Remove the upper spring (5), the diaphragm assembly
(6) and the shaft guide disk (7).
• Use a 1" socket wrench to withdraw the nut (8) and
have access to the sealing ring, the valve shaft and
the lower spring (9).
Disassembly of the filtering elements and valve
Before you start disassembling, close the air supply and drain the
filter to relieve the internal pressure of the bowl.
• Remove screws (11) and manually remove the bowl
(29).
• Remove the nut base by turning it counter clockwise
(23) and remove the elements (21) (22).
• Take out the sealing rings.
Cleaning and lubricating
• Wash all parts.
• After cleaning, carefully dry all parts.
• Inspect the parts and replace the damaged ones with
new DeVilbiss parts.
• Lubricate o-rings and movable parts with a silicone
free lubricant.
• Before assembling the outfit, clean the body with a
cloth and dry with compressed air.
AttENtION
DeVilbiss reserves the right to modify the characteristics of its
products without previous warning.
