Duskolectors

Hammond DusKolectors® are independent dust collectors used for isolated machines that cannot be connected to a central dust collection system, or where no central system is available. In operation, the DusKolector® draws the dirty air inside itself where the heavier particles are deposited in a dirt container at the bottom of the machine; either a tray or a 55-gallon drum. The air then goes through filters which remove the finer particles, and the filtered air returns to the room. There is no waste of energy exhausting heated or cooled air to the outside of the building. DusKolectors® are available in three models: cabinet, cyclone, and CycloPlus. Optional DK-655 with 55 gallon drum

CycloPlus Model

The CycloPlus (CDK) models range from 5500 to 5900 CFM. These models require relatively little floor space, offer better filtration and extended cartridge life, and are suitable for a wide range of applications.

During collection, primary filtration is by conventional cyclonic action. As much as 75-90% of heavy particles drop out in the dirt container. Escaping fines are captured on the surface of the pleated cartridge filter inside the DusKolector® body. Acting only as a final filter, the cartridge is not overloaded and can clean airstreams with up to 99% efficiency, and trap dust particles down to 1 micron in size.

During cleaning, the reverse pulse-air jet continuously cleans the cartridge on a timed cycle. Loose particles are blown into the outer cyclone air stream and carried to the dirt container; not redeposited on the cartridge filter. The CycloPlus cartridge filter stays cleaner and lasts longer than other models.

The illustrations below show the CDK during collection and during cleaning.

DUSKOLECTOR® APPLICATIONS

The following information is designed as a guide for selecting the right DusKolector® for your application. The first consideration is the CFM required for each dust-producing machine. The minimum CFM required for popular types of machines is shown below. The data is in accordance with the Industrial Ventilation Manual.

The volume, weight, and nature of the material being collected are other factors to be considered. In order to capture the dust, hoods or scoops must fit closely around the work point, and the DusKolector® should be located as close as possible. Duct runs should have a minimum of elbows, bends and vertical rises. Proper ductwork is important to provide maximum efficiency.

CFM vs. STATIC PRESSURE

Hammond DusKolector® CFM and static pressure ratings are arrived at by following the Air Movement and Conditioning Association test code procedures. The chart below is useful for complex, multiple machine installations. Total external static pressure is determined by hood entry loss; length of straight duct; and number of elbows and branch entries. For simpler applications, refer to the Maximum Collection Capacity for each DusKolector® model.

OPERATION SAFETY

Hammond DusKolectors® are designed to be effective and easy to use, but three caution plates are attached to each machine and these warnings must be heeded to insure safe operation.

Below are special considerations when collecting combustible dusts.

Never use the same DusKolector® to collect multiple spark generating materials, e.g. aluminum with steel.

Never use spark generating workholders or fixtures.

Never introduce fire into the DusKolector® system.

Never use a flammable finishing lubricant.

Never use flexible hose for branch or main duct runs.

Never allow accumulations of combustible dusts to remain in the system.

Empty the DusKolector®, bins, drums and bags frequently.

Clean the source machinery, hooding and ductwork regularly.
