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.
