Description

The Downflo II dust collector is a continuous-duty, modular collector with cartridge-style filters. The downward airflow design delivers high filtration efficiency while using less energy. Continuous-duty means no downtime. The filters are pulse-cleaned in sequence, one set at a time, without turning the unit off. The modular design allows flexibility in system design and adapts easily to limited space areas. Each standard module is two or three filter rows wide by two, three, or four rows high by two filters deep.

Designed to increase the versatility of the unit, standard options include abrasion-resistant inlets, extended dirty-air plenums, and air management modules. Quick-removal access covers, the Drum Sentry�, Bag-Out, cold-climate kits, and steep-sided ledge-free hoppers are among the many options available to customize the Downflo II to the specific application.

Purpose and Intended Use

Downflo II collectors are widely used on nuisance dust where the load to the collector is less than two grains per cubic foot. Some typical applications include abrasive blasting, grinding, pharmaceuticals, powder paint applications, sand handling, and welding. Each application is different and selecting the correct filter cartridge for the application and type of dust collected is important.

� For all ambient, extremely fine, and non-fibrous dust, use Ultra Web® filter cartridges which offer high efficiency and performance on fine particulate.

� For fibrous dust, use a cartridge with an open-pleat design, such as Fibra-Web®.

� Operations involving high temperature and high humidity may require special attention.

Temperature, moisture content, and chemistry issues may require custom collector design.

Appropriate cartridge options are available from Donaldson.

� Hygroscopic dust such as fertilizer, salt, and sugar should be handled under a controlled, low humidity environment. Contact Donaldson for filter cartridge selection.

� Flammable or explosive dust may require custom collector design options and special cartridges. Contact Donaldson for design assistance.

� Applications with high hydrocarbon or high oil content may require special treatment or filter media.

Caution!

� Misuse or modification of this equipment may result in personal injury.

� Do not misuse or modify.

Operation

During normal operation, dust-laden air enters the unit through the dirty-air inlet. Airflow is directed downward through the collector and heavier particulate falls directly into the hopper. The cartridges remove fine particulate and clean filtered air passes through the cartridges to the clean-air chamber and discharges through the clean-air outlet.

Filter cleaning is completed using pulse-jet technology. A solenoid and diaphragm valve aligned to each row of filters provides the pulse cleaning. The cleaning sequence starts at the top filter row and continues down through each row.

Remove, inspect, or change the cartridges from outside the unit by removing the filter access cover and sliding the filters out.

Solenoid Connection

The unit is equipped with 115-Volt solenoid valves that control the pulse-cleaning valves, which clean the filters.

lne of three types of solenoid enclosures, the weatherproof NEMA 4 with 3D2 solenoids, the explosion proof NEMA T with 5D2 solenoids, or the explosion proof NEMA V with 5D2 solenoids, is mounted near or on the unit�s compressed-air manifold.

Wire the solenoids to the solid-state timer following the wiring diagram supplied with the unit. cilter life and cleaning operation will be affected if not wired correctly.

Timer and Solenoid Specifications

Power to the solid-state timer is supplied to Terminals L1 and L2, which operate in parallel with the fan starter�s low-voltage coil. ln fan start-up, power is supplied to the timer and the preset lcc time is initiated. At the end of the lcc time, the timer energizes the corresponding solenoid valve to provide the lN time cleaning pulse for one diaphragm valve and then steps to the next until all filters have been cleaned.

To pulse when the fan is lcc, install a toggle switch as shown on the Solid-State Timer Wiring Diagram. When the toggle switch is lN, the timer receives power and energizes the solenoid valves� pulse-cleaning operation even though the fan is turned lcc.

Transition and Rotary Valve

The 7-inch tall transition is designed to connect a standard hopper and a rotary valve. Rotary valves are used as an airlock and a metering device in dust control applications. When used as an airlock, an airtight seal between the valve�s inlet and outlet is maintained while allowing dust or material to pass through. Comparatively, the airlock works along the same line as a revolving door on a building; an airtight seal is maintained while people are allowed to pass through.

When used as a metering device, the valve allows a specific amount of material to pass per revolution, depending on the size and speed of the valve. Sizing is determined at time of order and based on product load. Standard sizes include 8, 10, 12, and 16-in inlets.
