Risk of personal injury.
Risk of property damage.
Except as otherwise specified by the manufacturer,
this product is specifically designed for compressed air
service and use with any other fluid (liquid or gas) is a
misapplication. For example, use with or injection of
certain hazardous gases in the system (such as oxygen
or liquid petroleum gas) could be harmful to the unit or
result in a combustible condition that may cause fire or
explosion. Manufacturer’s warranties are void in the
event of misapplication and manufacturer assumes no
responsibility for any resulting loss.
DESCRIPTION
This 100 CFM filter (Model HAF-502) is designed to remove dirt,
pipe scale and most liquid aerosol. It includes a 5 micron filter
element. A model with 50 CFM air regulator is also available
(Model HFRL-508).

INSTALLATION
Risk of injury. Release all air pressure from system before
servicing system. Do not place unit in service without
metal bowl guard installed. Plastic bowl
units are sold only with metal bowl guards. To minimize
the danger of flying fragments in the event of plastic bowl
failure, guard must not be removed. If the unit is in service
without the metal bowl guard installed, manufacturer's
warranties are void and the manufacturer assumes no
responsibility for a resulting loss. If unit has been in
service and does not have a metal bowl guard, order one
and install before placing back in service.
Certain solvents, paints and chemicals may attack plastic
bowl and can cause bowl failure. Do not use near these
materials.
IMPORTANT:
Read and follow all instructions and SAFETY PRECAUTIONS
before using this equipment. Retain for future reference.
1. Be sure to read all
"WARNINGS"
and
"CAUTIONS"
in
this manual and on the unit before installation or using this
equipment.
2. Install filter as close as possible to point where air is
being used. Install main air shut-off valve and standard
pipe union (supplied by user) upstream of filter to allow
maintenance to unit.
3. Install unit with air flow through filter in direction of arrow on
top of unit.
4. Minimum 1/2" piping is recommended. Avoid using
fittings, couplings, etc. that restrict air flow.
5. A 1/2" street elbow will be needed to allow vertical pipe
installation. Mount filter in a vertical position.
6. Do not install filter in an application where the pressure drop
will exceed 20 psi. For example, a quick opening valve
located upstream from the filter could cause a momentary
pressure drop in excess of 20 psi.
7. Install "T" handle into regulator (Model HFRL-508).
8. Maximum inlet pressure and operating temperature is:
150 PSIG (10.3 bar) and 150
°
F (65.6
°
C).
9. A 6' length of vinyl tubing is shipped loose with the unit.
Slide over automatic drain which protrudes from bottom of
bowl. Place other end of vinyl tubing into appropriate recep-
tacle (i.e. below booth grating, can, etc.). Prevent vinyl tubing
from becoming kinked which would prevent free movement
of liquids discharged from the automatic drain.
10. An optional manual drain (HAF-11) is supplied loose in the
carton (see item 10, Fig. 2). If desired, this can be installed
in place of the automatic drain.
OPERATION
After unit is installed and ready to use:
1. Attach air hose(s) to outlet ball valve(s), selecting regulated
and/or non-regulation according to the application.
2. Open main shut-off valve upstream of filter.
3. Main line air pressure is monitored by the top air gauge.
4. Adjust regulator to desired setting by turning "T" handle
in or out.
5. Open ball valve(s) to supply air to spray gun or tool being
used. With air flowing, readjust air pressure at regulator
if necessary.
6. After use, shut off ball valve(s) and bleed off residual air in
hose(s).
MAINTENANCE
Certain solvents, paints and chemicals may attack plastic
bowl and can cause bowl failure. Do not use near these
materials. When bowl becomes dirty, wipe only with a
clean, dry cloth. Immediately replace any crazed, cracked,
damaged or deteriorated plastic bowl with a new plastic
bowl. Reinstall metal bowl guard.
1.
If bowl is equipped with manual drain, drain bowl at least
once per shift. Units with automatic drain will drain auto-
matically.
2.
Before performing maintenance on unit, close main
shut-off valve located upstream of filter. Bleed off residual air
in unit.
3.
To open filter, press button located on clamp ring and
rotate ring either clockwise or counterclockwise. The metal
bowl guard and plastic bowl can then be removed from the
filter head.
