Typical Take-off Compartment
3-21 Adjusting Fast Take-off (FCO) Compartments
When adjusting fast take-off compartments, make adjustments in
small increments (especially in systems with long runs) to allow air
flow to equalize throughout the system.
FCO-1.5M
In some applications, material flow characteristics may require a
more defined air-to-material ratio. You can do this easily by
covering one or more of the aeration holes located at the top of the
inlet tube in FCO-1.5M fast take-off compartment models.
FCO-1.5MD
The FCO-1.5MD model fast take-off compartment has adjustable
inner tubes fitted to the fixed outer tube. These adjustable inner
tubes are locked down by a hold-down screw on the outer tube.
Loosen this screw to adjust the inner tube.
When the adjustable inner tube is completely inside the material
compartment and the indicator knob is in a vertical position, no
material can be conveyed in the system. Adjust the tube by pulling
it away and keeping the indicator knob vertical.
The maximum amount of material can convey when the reference
hole on the adjustable inner tube is outside the edge of the outer
tube. Vary the amount of material conveyed by rotating the inner
adjustable tube.
