WARNING!
Shear points are present at the
open inlet and outlet of the rotary airlock.
For safety, you must cover the inlet and outlet
before performing this procedure!
THE AIRLOCK COULD SHEAR OFF YOUR FINGERS
if you do not take adequate safety measures!
HAND GUARDS ARE REQUIRED.
Note:
• The rotary airlock is a precision-machined device. Exerting twisting or
pulling pressure on the housing (as with poor installation of related
components) causes damage, excessive wear, and air leaks.
• The shaft seals are shipped loose and must be tightened before running
material through the airlock.
5. Install and/or inspect the optional rotary level indicator.
6. Mount the cyclone on top of the rotary airlock. The legs provided to the
airlock support the entire assembly. If the self-cleaning filter is purchased,
mount the airlock with the blow-through adapter to the discharge flange of
the filter receiver. The airlock/blow-through adapter can be oriented so the
airlock housing does not interfere with the filter receiver legs. Use the one
eighth inch (
1 /
8
”; about 3 mm) -thick composite gaskets. Tighten bolts
evenly to avoid distorting flanges. Draw up snug—do not over-tighten.
7. Take care to align the pressure blower discharge muffler and the blow-
through adapter. Airlocks are precision-machined devices. Do not load or
twist the housing.
8. Connect the discharge end of the pressure blower to the inlet side of the
discharge adapter. Black heavy-duty high-temperature oil-resistant hose is
provided for the connection.
