Air Take-Off Compartment
Levels A and C
The FCO-1.5MD model fast take-off compartment has an adjustable inner tube fitted to the fixed
outer tube. A hold-down screw on the outer tube locks down the adjustable inner tube. Loosen
the screw to adjust the inner tube.
Vary the distance of the indicator knob from the outer collar (See Figure 6) to control the flow of
material to be conveyed. Adjust the inner tube so that the inside edge of the vertical knob
touches the outer collar. This position is the minimum and factory-recommended setting. The
minimum and factory setting should adequately meet the throughput requirements on
SDAP cart systems.
For higher flow rates, increase the distance by pulling the adjustable tube away until you get the
flow rate you want. The maximum amount of material should be conveyed when the adjustable
inner tube is pulled all the way out.
Note: This condition may cause the flow to be unsteady, and
eventually may plug up the line.
Along with the take-off adjustment, take special care when setting the convey time:
• Too short of a time shortens the service life of the blower.
• Too long of a convey time causes material to back up in the convey line, which could lead
to plugging.
Suggested convey time is a minimum of five (5) seconds and a maximum of twelve (12)
seconds.
Basic Tips
Every material has different conveying characteristics because of factors such as bulk density
and particle size. Some material is easier to flow than others. That is why the inner tube is
adjustable to give you the flexibility to control how much material you want to convey.
1. When adjusting the inner tube, always adjust from the inside out. Start from the tube
positioned all the way in (minimum setting), then slowly pull the inner tube out until the
distance from the outer edge to the indicator knob is one eighth of an inch (
1 /
8
” / 3 mm).
This is the eighth-inch ( 1 /
8
” / 3 mm) setting.
