Dustin-Mizer Powder Duster is a lightweight yet tough solution to applying powdered Diatomaceous Earth to your gardens, lawn, or animal areas. The convenient hand crank helps distribute an even flow of the dust from the 16-inch tube. The hopper holds 1 pound of powder, depending on density, and the rate of application will depend on the speed you turn the crank. At 72 RPM, the duster will produce 35 cubic feet of air per minute. This enables swift yet controlled application of any powdered product. Doktor Doom products are available for fall booking. Inventory is restocked once per year.
