Operational Description - Centrifugal Separator
As the air, gas, or steam flow enters the separator, it is forced through a centrifugal element. There the heavier moisture droplets and dry particles are centrifuged to the outer periphery of the flow and are impinged against the vessel's wall. The flow forms a helical pattern as its path extends to the drain side of the separator. The flow then reverses by way of a center vortex. This center return vortex is a danger point where re-entrainment is most likely. The exclusive Eaton Vortex Containment Plate "VCP" combats re-entrainment by providing a quiet zone where the entrainment is permitted to fall out of the flow. This arrangement effectively segregates the removed entrainment from the outlet flow.
Maintenance and Spare Parts
Eaton separators have no moving parts. All components are either bolted or welded into place. Therefore parts lists are not available. The separators are bolted, threaded, or welded into the lines. They are self-cleaning, and do not need lubrication or maintenance. For this reason, lubricating, operating and maintenance manuals are not available.
Eaton separators, when properly sized, installed, and drained, will remove 99% of all liquid and solid entrainment where particle size exceeds 10 microns.
All threaded connections not being used must be plugged at time of installation.
For Positive Drainage of Separator
Install trap a minimum of 6" below separator drain. For every inch of horizontal piping to trap, add one inch to the vertical piping. Do not reduce separator drain size except at trap inlet. Never (with one exception) allow the top of the trap to extend above separator drain connection. Add 1/4" balance (vent) line where shown for air and other gas (not steam) installations.
Air and Gas (not steam) Service
4" Type T cast iron separator removing moisture and oil from a compressed air line. No. 230-AC trap to drain. A sediment pocket, as shown, should be provided for air and gas service (instead of a strainer).
2" Type T cast iron separator removing moisture from a compressed air distribution line. 3/4" No. 90-AC float type trap installed below separator to drain. This is the only type air and gas drain trap installation that does not require a balance (vent) line.
Prime trap with water before turning air pressure on.
3/4" No. 90-AC SISO (side inlet, side outlet) float trap installed on air receiving tank where floor clearance is at a minimum
Above: 2" Type T separator installed in 300 PSI steam line to turbine. 1-1/4" "Y" strainer and 3/4" No. 95 steam trap to drain.
Below: 4" Type T separator removing moisture from a steam header at 125 PSI. One inch "Y" strainer and 350-C trap to drain.
