WSO Flex
INTRODUCTION
Product information
The WSO Flex mist collector is used for the collection of airborne mists. Whether in
answer to the problem of air pollution, or as part of a manufacturing process, the mist
collector provides highly efficient, continuous, on-line mist collection.
The WSO Flex mist collector is designed to collect oil, water soluble and synthetic
coolant mists from a variety of machining operations and other industrial processes.
The unit will also collect a small amount of dust from machining operations. With the
optional HEPA (High Efficiency Particulate Air) filter, smoke from machining operations
can also be captured.
The filter element is the heart of the mist collector. This filter element helps to ensure
that only cleaned air is returned to the plant environment. The filter element is either
a Dryflo or a Synteq XP element depending on the scope of the delivery.
Technical and field support are available from your local Donaldson representative or
distributor to answer your questions.
Function
During operation, contaminated air enters the WSO Flex mist collector through the
dirty air inlet, located on the bottom of the unit. The air then passes through the first
stage filter which is designed to collect and coalesce large droplets and particles.
After the first stage filter the air still contains smaller mist droplets.
For Dryflo element specific, the filter element wrap provides an additional level of
filtration compared to the Synteq XP element. This standard filter element wrap is
designed to collect and coalesce fine mist into larger droplets. The vertical orientation
of the wrap promotes drainage of the droplets. The filter element wrap also collects
particulate that may be in the airstream, extending the life of the third stage filter
element.
In the core and most efficient stage of filtration, the air passes through the filter
element.
As mist particles coalesce and form larger droplets, the droplets become large enough
to run down the filter element. During operation, the droplets will drain on both the
inside and outside of the filter element. The filtered air exits the filter element into the
clean air chamber, where it exits through the clean air outlet and can be recirculated
into the environment.
