Refer to Form 5S6040 for General Safety Information and Warranty
Description
Speedaire coalescing filters remove oil aerosols and submicron solid particles down to 0.01
micron from air supply lines by means of a coalescing filter element. Typical applications
include air bearings, air conveying, high speed air motors, pneumatic instrumentation and
controls, gauging equipment, and spray painting. Units are equipped with a manual drain.
Turn manual drain valve to drain accumulated liquids.
General Safety Information
Coalescing filters are utilized in a variety of
air system applications. Because the
coalescing filter and other components
(compressor, spray gun, filter, regulator,
hoses, etc.) make up a high pressure
pumping system, the following safety
precautions should be observed at all times.
1. Read the instruction manuals for each
component carefully before attempting to
assemble, disassemble, or operate your
particular system.
2. Do not exceed the pressure rating of any
component in the system.
3. Protect material lines and air lines from
damage or puncture.
4. Never point a spray gun at oneself or any
other person. Accidental discharge may
result in serious injury.
5. Check hoses for weak or worn condition
before each use, making certain that all
connections are secure.
6. Release all pressures within the system
before attempting to service any
component.
Water vapors will pass
through these units
and could condense into liquid form
downstream as air temperature drops.
Install an air dryer if water vapors could
have a detrimental effect on the
application.

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 or 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. Push bowl, or bowl with guard, into body
and turn fully clockwise before
pressurizing.
4. Install a Speedaire air line filter with a 5
µm element upstream of the coalescing
filter to obtain maximum element service
life.
Operation (See Figure 2)
1. Open manual drain to expel accumulated
liquids. Keep liquids below element (Ref.
No. 20).
2. Replace filter element when pressure
differential across element exceeds 10 psi.
The mechanical service indicator (Ref. No.
25) shows approximately full red when
pressure drop across the element reaches
10 psi. An excessive pressure drop across a
saturated but uncontaminated element
may indicate operation above maximum
flow rate (CFM). See Specifications.
Disassembly (See Figure 2)
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. Remove bowl. Push into body and turn
counterclockwise.
4. Disassemble in general accordance with
the item numbers on Figure 2. Do not
remove the drains or the service
indicators unless replacement is necessary.
Remove and replace only if they
malfunction or converting to automatic
drain.

Cleaning (See Figure 2)
1. Element cannot be cleaned. Clean plastic
bowl with warm water only. Do not
submerge electrical service indicator (Ref.
No. 27) in water. Clean indicator with dry,
clean cloth. Clean other parts with warm
water and soap.
2. Rinse and dry parts. Blow out internal
passages in body (Ref. No. 1) with clean,
dry, compressed air.
3. Inspect parts. Replace those found to be
damaged. Replace plastic bowl with a
metal bowl if plastic bowl shows signs of
cracking or cloudiness.
Assembly (See Figure 2)
1. Lubricate o-rings, the portion of the
manual drain body (Ref. Nos. 5 & 13) that
contacts the bowl, and the hole in the
manual drain body that accommodates
the stem of drain valve (Ref. Nos. 3 & 11)
with o-ring grease.
2. Assemble filter as shown on Figure 2.
Arrows on indicator (Ref. Nos. 25 & 29)
and body must point in same direction.
3. Torque items listed in Torque Table.
4. Push bowl, or bowl with guard, into body
and turn fully clockwise
