Air Supply
1. Install an air filter (AF series) as a pre-filter on the inlet side of
the mist separator to prevent premature clogging.
2. Install a mist separator (AFM series) as a pre-filter on the inlet
side of the micro mist separator to prevent premature clogging.
3. Do not install on the inlet side of the dryer as this can cause
premature clogging of the element.
Caution
Maintenance
1. Replace the element every 2 years or when the pressure drop
becomes 0.1 MPa, whichever comes first, to prevent damage
to the element.
Warning
Design
1. Design the system so that the mist separator is installed in a
pulsation-free location. The difference between internal and
external pressure inside the element should be kept within 0.1
MPa, as exceeding this value could cause damage.
Caution
Selection
1. Do not allow air flow that exceeds the rated flow. If the air flow
is allowed outside the range of the rated flow even momenta-
rily, drainage and lubricant may splash at the outlet side or
cause damage to the component.
2.
Do not use in a low pressure application (such as a blower).
F.R.L. unit has its own minimum operating pressure depending
on the equipment and is designed specifically to function with
compressed air. If used below the minimum operating pressure,
a loss of performance and malfunction can occur. Please contact
SMC if an application under such conditions cannot be avoided.
Caution
Be sure to read this before handling. Refer to “Precautions for Handling Pneumatic Devices” (M-03-E3A) for Safety Instruc-
tions and F.R.L. Units Precautions.
