Sprinkler Installation
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.
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 20 gallons per minute.
Consult with local authorities
when installing fire control
systems on dust collection equipment.
