TD486 Dust CollectorsIntroductionThe Torit TD Dust Collector is used for collectionof airborne dust and particulate. Whether inanswer to the problems of air pollution or as apart of a manufacturing operation, Torit TDs provide continuous operation.Operational Explanation (See Figure 2)Normal OperationDuring normal operation, dust enters the inlet andis collected on the outside of the elements. The filtered air passes up through the venturis andplenum and out the blower outlet or outlet collar.Noise LevelA certain level of noise is created with any airmoving device. If for any reason this noise level isabove a tolerable level, exhaust silencers are available from Donaldson Torit as optional equipment.Contact your Donaldson Torit representative foroptional accessory blowers, attenuators, filter elements.Normal OperationFilter CleaningFilter element groups are cleaned automaticallyand alternately. The result is that at any one timeonly one group of elements is taken off stream forcleaning, while the remaining elements are still inoperation. Elements are: 7-7/8 O.D., 3-9/16” I.D.,by 16” long.During filter element purge, the solid-state controltimer automatically selects the elements to becleaned and energizes the air valve solenoid. Theair valve opens, sending a pulse of compressed airinto the blowpipe and down through the venturis.The compressed air pulse and induced air passthrough the filter elements from the inside outward, removing the dust from the outside of theelements. The dust falls into the hopper. At the endof the 100 millisecond pulse, the air valve closesand the elements are back in operation.Element Purgeblowpipeplenumventuriinduced airelementsair pulseFigure 2, Operational Schematics5
Donaldson Company, Inc.HoppersAssembly of Standard EquipmentStandard hoppers are at least 59 as viewed from ahorizontal reference and have one inlet.Note: A crane is recommended for the unloading,assembly, and installation of the dust collector.Hopper discharge clearance on standard hoppers is48”. Other hopper clearances are available on special order—for information on optional clearances,contact your local Donaldson Torit Products representative.InstallationCAUTION! Connect the lifting sling to a minimum of four (4) cabinet lifting lugs. Distribute loads evenly. Connect the lifting sling to doublethickness cabinet lifting lugs whenpossible. Use clevices, not hooks, on the liftingsling. Use spreader bars on the lifting sling.InspectionThe TD dust collector is normally shipped by common carrier truck and should be checked for anydamage that may have occurred en route. Anydamage should be noted and the carrier notifiedimmediately.Pre-Installation (See Figure 1)The weight of the dust collector and all auxiliaryequipment must be considered when planning forthe foundation. See individual SpecificationControl Drawing for dust collector weight.See Specification Control Drawing for anchor boltlocation. The 3/8” anchor bolts must extend1-3/4” above foundation. The collector locationshould be determined with consideration for emptying the hopper, shortest run for the location ofduct work, electrical and air connections andmaintenance. In the case of hazardous dust, consult with local authorities for the location of theunit.Remove all crating and strapping from the unit.All parts, bolts, nuts, etc. are shipped inside of theunit. Remove before lifting unit off the pallet.6Note: Each item to be attached to your collector isaccompanied by a drawing that shows the attachment. Refer to both the drawings and this manualwhen erecting your collector.Hopper to cabinet assembly is done on the job site.Remove hopper from pallet and stand on hopperdischarge opening. Apply 1/4” diameter sealer tothe hopper flange (see Parts Drawing 1 CabinetAssembly) NOTE: Apply sealer inside bolt holes.Lift cabinet from pallet and position on top ofhopper.

TD486 Dust CollectorsElectrical InstallationCAUTION!Disconnect electrical power beforeservicing any electrical component.2. Input: 105-135 VAC, 50-60 Hz.3. Output: Type—solid state switch (triac). Theload is carried by and turned on and off by thetriac. Rating—200 watts maximum load peroutput.4. Pulse Width: Factory-set at 100 milliseconds.Note: All electrical work must be done by a qualified electrician according to local codes.Continuous duty TD—standard TD units areequipped with 120 VAC solenoid valves rated at14.6 watts each, and a solid-state electronic120/60/1 control timer.Note: Solid-state TD control requires a low voltage(120 V) control circuit in fan circuit to be suppliedby others.TD Solid-State Timer Specifications (AutomaticCleaning Only)1. Operating Logic: Input power is applied to L1and L2 of the timer control circuit board whichis in parallel with the low voltage (120/60/1)coil of the fan magnetic starter. Upon fan startup, power is supplied to the control board andthe preset OFF time is initiated. At the end ofthe OFF time, the control will energize a solenoid to provide the cleaning pulse for one segment of the filter elements and then step to thenext segment. This cycle is continuous unless anauxiliary control, such as a pressure switch, isused to control the timer. See Figure 3,Operating Logic Diagram.5. Off Time: Adjustable between ranges shown. 1to 1.5 seconds minimum, 60 to 66 secondsmaximum (factory set).6. Operating Temperature Range: -20 to 130 F.7. Transient Voltage Protection: 50 KW transientfor 20µs duration once every two seconds.TD Solid-State Timer Installation InstructionsNote: All electrical work must be done by a qualified electrician according to local codes.1. Install proper sized starter (with low voltagecontrol circuit) conduit and wires for fan motor.2. Using wiring diagram (Figure 5 Wiring Diagramand inside control timer cover), make properconnections to fan motor, fan motor starter,solid state timer, and solenoid valves.Note: In grounded systems, neutral to control boxmust be connected to L2 of the control terminalboard.9
Donaldson Company, Inc.3. Bump the fan motor and check for proper rotation by referencing the rotation sticker locatedon the motor mounting plate. To prevent possible eye injury, wait for the wheel to run downto a very slow speed and wear eye protection.Proper fan rotation is extremely important. Even ifthe fan is running in the wrong direction, it willdeliver approximately 40% of its rated air volume,but it will required more then its rated horsepower.If rotation is in the direction opposite the arrow,simply reverse any two leads (3 phase only) on theoutput of the fan motor starter.4. Check operation of the solenoid valves. Thesevalves should open and close continuously witha factory-set dwell between each pulse.Note: To reduce compressed air consumption, aPhotohelic * or similar device can be used, allowing valves to pulse only when pressure reaches setpoint.5.
