Air management module
The air management module is used in applications involving heavy grain loading,
large or abrasive particles in the airstream, or in applications when a collector with
a single inlet serves multiple modules. It is equipped with a louvered panel near the
bottom, which prevents re-entrainment of the dust that falls through to the hopper.
This module does not contain filters, and is available for use with an extended dirty-
air plenum only.

Sprinkler
Sprinklers can place a large quantity of water in the dust collector when
activated. Provide adequate drainage to remove water. Excess water weight
can cause the leg structure to collapse.
Fire control sprinklers are available for models operating under negative pressure.
Donaldson Torit supplied sprinklers require a minimum of 1 bar water pressure which
will produce a discharge per sprinkler head of 77 liters per minute.
Consult with local authorities when installing fire control systems on dust
collector equipment.
1. Remove or open the filter access covers to access the sprinkler tap located in
the dirty-air plenum.
2. Apply pipe sealant to the threads of the pipe reducer located on the sprinkler
assembly.
3. Thread sprinkler assembly onto the 1-in diameter sprinkler tap.
4. Tighten securely.
