WSO Mist Collector, WSO 25-4 and 25-6
4
Standard Equipment
The collector has a high center-of-gravity and may overturn if not secured properly.
Secure the collector to the lifting device.
Use care when moving the collector.
The WSO mist collector is shipped in three sections, a hopper plenum, a primary filter plenum and a fan support plenum. If there is
an afterfilter plenum, it will ship attached to the fan support plenum. The fan will ship loose.
Options and Accessories
Final Filter
Filter air can then be passed through a final filter to separate fine dust particulates which may have passed through the primary
filter.
Drain Collection Container
The optional drain collection container is intended for use where small amounts of liquid are collected and requires regularly
scheduled maintenance. Failure to empty the collection bottle will result in inlet plenum overflow.
First Stage Filter
Air laden with dirt and coolant mist passes through the dirty air inlet and into the hopper. First is passes through a reusable first
stage filter designed to collect and coalesce large coolant droplets which drain into the hopper.
Primary Filter
After passing through first stage filter, prefiltered air then passed through a primary filter where fine coolant droplets and mist
coalesces and again drain into the hopper.
Final Filter (Optional)
Filter air can then be passed through a final filter to separate fine dust particulates which may have passed through the primary
filter.
P-Trap with Optional Y-Strainer
Dirty coolant collected in the hopper flows through a standard P-Trap designed to drain coolant while maintaining a seal. Dirt can
be removed from the P-Trap by flushing with coolant or opening the optional strainer.
Sprinkler Coupling
Sprinkler couplings are provided for the convenience of fire control system installers. The fire control system installer shall make
their own decisions on the appropriate location of fire control system components.
Magnehelic
®
Gauge
The Magnehelic is a differential pressure gauge used to measure the pressure difference between the clean- and dirty-air plenums
and provides a visual display of filter change requirements. The high-pressure tap is located in the dirty-air plenum and the low-
pressure tap is located in the clean-air plenum.
