Norgren F22 Installation Instructions
DISASSEMBLY
1. Filter can be disassembled without removal from air line.
2. Shut off inlet pressure. Reduce pressure in inlet and outlet
lines to zero.
3. Disassemble in general accordance with the item numbers
on exploded view. Do not remove the drains unless
replacement is necessary. Remove and replace drains only
if they malfunction.
CLEANING
1. Clean parts with warm water and soap.
2. Rinse and dry parts. Blow out internal passages in body (1)
with clean, dry compressed air.
3. Inspect parts. Replace those found to be damaged.
ASSEMBLY
1. Lubricate seals and o-rings with o-ring grease. Apply a
small amount of anti-seize lubricant to full length of
threads on metal bowl.
2. Assemble filter as shown on the exploded view.
3. Torque Table
Item Nm (Inch-Pounds)
6 (retainer) 0,8 to 1,1 (7 to 10)
11, 15, 18 (nut) 2,3 to 2,8 (20 to 25)
24 (baffle) 1,1 to 1,4 (10 to 12)
CAUTION
Do not over torque retainer (6) as damage to gauge glass
(9) will occur.
4. Turn bowl clockwise into body until stop (approximately 5
turns), then unscrew no more than one full turn to position
sight glass for best visibility. Do not attempt to turn bowl
when filter is pressurized.
CAUTION
Water vapor will pass through these units and could
condense into liquid form downstream as air temperature
drops. Install an air dryer if water condensation could have a
detrimental effect on the application.
WARNING
These products are intended for use in industrial
compressed air systems only. Do not use these products
where pressures and temperatures can exceed those listed
under Technical Data.
Do not substitute any other bowl for the stainless steel
bowl furnished with these products.
Before using these products with fluids other than air, for
nonindustrial applications, or for life-support systems consult
Norgren.

INSTALLATION
1. Shut-off air pressure. Install filter in air line -
● vertically (bowl down),
● with air flow in direction of arrow on body,
● upstream of regulators, lubricators, and cycling valves,
● as close as possible to the air supply when used as a
main line filter,
● as close as possible to the device being serviced when
used as a final filter.
2. Connect piping to proper ports using pipe thread sealant
on male threads only. Do not allow sealant to enter
interior of unit.
3. Flexible tube with 3 mm (0.125") minimum I.D. can be
connected to the automatic drain. Avoid restrictions in
the tube.
4. Before pressurizing, turn bowl clockwise into body until
stop (approximately 5 turns), then unscrew no more than
one full turn to position sight glass for best visibility.
SERVICING
1. Open manual drain to expel accumulated liquids. Keep
liquids below baffle (24).
2. Replace filter element (26) when dirty or when pressure
drop across element exceeds 0,7 bar (10 psig).
