MODELS F222 & F451 LIQUID/PARTICLE FILTERS
Specifications - Installation and Operating Instructions
Bulletin IN-F221
Coalescing compressed air filters protect equipment and
instrumentation from harmful contaminants such as dirt,
water, and oil. Liquids are continuously coalesced and
released through the manual drain valve. Replaceable filter
element removes particles and droplets as small as 0.1
micron with 93% efficiency. Each assembly comes
complete with a filter cartridge and a manual drain valve.
MODEL NUMBERS
INSTALLATION
The model F222 coalescing compressed air filter is
designed to be mounted in-line. The unit is equipped with
1/4” inlet and outlet ports. An arrow, indicating flow
direction, is molded into the head assembly. When installing
make sure the inlet and outlet ports follow the direction of
the indicating arrow.
The model F451 coalescing compressed air filter has 1/4”
NPT(F) inlet and outlet ports. The unit also has 1/4-20
mounting holes tapped for panel mounting or mounting on
a bracket. Follow flow direction on label.
Warning: Be sure the media being used is compatible with
the material used in constructing the filter assembly. Do not
expose filter assemblies to solvents, alcohols, or glycols.
Exposure to these materials could cause failure of the
housing. Use only non-detergent mineral base oils. Use of
other oils could lead to dangerous failure of the product.
OPERATION
All installation and maintenance activities should be
performed using reasonable care. Turn off compressed gas
supply and depressurize the filter housing prior to
performing routine maintenance.
A manual drain valve is located at the bottom of the filter
bowl. For model F222, open drain valve by depressing drain
pin. Pin will automatically return to closed position when
pressure is removed. To release coalesced liquids from
model F451, turn stopcock clockwise. Turn
counterclockwise to close drain valve.
Both filter assemblies include a replaceable filter element.
The filter element should be replaced when a noticeable
pressure drop occurs across the filter assembly. How often
the element needs to be replaced is strictly application
dependent. Replacement filter elements are available for
both models. See table above left for correct model
numbers.
