CAUTION!
Personal injury, death, or property
damage can result from material
discharge during venting.
The material discharged from an
enclosure during the venting of an
explosion should be directed safely to
an outside location.
The risk of damage or injury can be
minimized or avoided by locating
vented equipment outside buildings and
away from normally occupied areas.
Standard explosion vents are intended
for outdoor installations only.
Explosion Vents
Note: Remove all shipping materials, including
covers, from the explosion relief vents
prior to installation. Failure to remove
shipping covers will seriously compromise
explosion vent operation.
Explosion relief vents must be safely directed
outdoors away from personnel, buildings,
property, offices, walkways, and catwalks to
reduce risk of damage to property and personal
injury. Explosion venting calculations are based
on formulas from NFPA-68, for outdoor
applications only, with no duct or obstructions
on the explosion vent panel.
Explosion vents are suitable for negative pressure
installations only.
Contact Donaldson Torit for assistance in
calculating safe and specific venting requirements
for equipment.
Sprinkler Installation
CAUTION!
Sprinkler systems 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.
Sprinkler Installation
Optional fire control sprinklers are available for all
models operating under negative pressure.
Donaldson Torit supplied sprinklers require a
minimum of 15-psig water pressure to each module.
The volume of water discharged per sprinkler head is
17 gallons per minute.
Note: Consult with local authorities when installing fire
control systems on dust collection equipment.
1. Remove the top filter access doors and filters
to access the sprinkler taps 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.
