Table of Contents◗CLUTCHES“Air Champ” ®DPC SERIESDUAL PLATE CLUTCHESThis Series, specified bycomponent, allows you to customdesign for specific applicationrequirements:◗ Static Torque capacity up to36,000 In. Lbs. @ 80 psi◗ Maximum Operating Speed up to2200 rpm◗ Thermal Horsepower values of3.3 to 9.0 at rated speeds◗ Components combine in a varietyof options to fit almost any need◗ Choose from Thru-Shaft orShaft-End Mounting◗ Choose between Sheave or Pilotstyle configurations◗ Rotary Air Union is included witheach Clutch Assembly.With the DPC Model Series, toughapplications are made easy. Each ofthe 4 Models and their manyoptions are detailed on the next fewpages.The DPC Series Clutches are designed for applications involving high inertia startsand stops. The Peak Input Rate may be the limiting factor in high inertia starts orstops, even though the Heat Sink Capacity is sufficient. The Peak Input Rate capacityis the rate at which the clutch absorbs heat at the <strong>friction</strong> interface during theacceleration period, while the interfaces are slipping or until the load and clutch areoperating at the same speed. See page 368 in the Engineering Data Section forinformation explaining how to calculate the Peak Input Rate and how to avoidpotential problems.◗ HOW TO SPECIFY AND ORDER DPC CLUTCHES:1. Determine if you require Shaft-End Mounting or Thru-Shaft Mounting;2. Determine if you require a Pilot Mount or Sheave Mount configuration;3. Determine which bore size you will need;4. Order each component individually, based upon your requirements.◗ MOTOR FRAME, SHAFT DIAMETERS & LENGTHSThis chart can be used for quick selection of many criteria.If you are using a standard motor frame and are within the rpm and horsepowerrequirements, the chart indicates a clutch and shaft to use.If you know the rpm, horsepower and desired clutch, the chart will indicate astandard motor frame and shaft to use.HORSEPOWER 600RPM 900RPM 1200RPM 1800RPM50 DPC13T DPC11T DPC9T DPC9TMotor Frame 445T 404T 365T 326TShaft DIA./LGTH 3.375 / 8.25 2.875 / 7.0 2.375 / 5.625 2.125 / 5.060 -- DPC11T DPC11T DPC9TMotor Frame -- 405T 404T 364TS, 364TShaft DIA./LGTH -- 2.875 / 7.0 2.875 / 7.0 2.375 / 5.62575 DPC13T DPC13T DPC11T DPC9TMotor Frame D5005 444T 405T 365TS, 365TShaft DIA./LGTH 3.5/ 10.25 3.375 / 8.25 2.875 / 7.0 2.375 / 5.625100 DPC15T DCP13T DPC13T DPC11TMotor Frame D5008 445T 444T 405TS, 404TShaft DIA./LGTH 4.0 / 11.75 3.375 / 8.25 3.375 / 8.25 2.875 / 7.0125 -- DPC13T DPC13T --Motor Frame -- D5005 444T --Shaft DIA./LGTH -- 3.5/ 10.25 3.375 / 8.25 --150 -- DPC15T DPC13T --Motor Frame -- D5005 445T, D5005 --Shaft DIA./LGTH -- 3.5/ 10.25 3.5/ 10.25 --◗ CLUTCH APPLICATION DATAMODEL DPC-9T DPC-11TPeak Input Rate 50 hp 84 hpEffective Friction Areas 55 in 2 93 in 2MODEL DPC-13T DPC-15TPeak Input Rate 131 hp 149 hpEffective Friction Areas 145 in 2 166 in 2◗ TORQUE VS.

Attach the End Cap to the end of the Hubwith three cap screws.2. Install the Rotary Air union and elbowfittings in the End Cap.3. Connect the cylinder hoses to the elbowfittings.AIR INLET4. Use the flexible hose (supplied) toconnect air supply to the Rotary Air Union(do not use rigid pipe or tubing for thisconnection).5. Make sure that of these hoses do notinterfere with the rotating parts of the unit.◗ MOUNTING/AIR INLETCONNECTIONSDPC Clutches are very flexible unitsbecause of their many mounting possibilities.Four of the more common applicationsare shown at left. Also refer to the AirInlet Connection information (at left)for each mounting style.◗ THRU-SHAFT MOUNTINGAIR INLET CONNECTION:1. Drill a 0.375 inch diameter hole in thecenter of the shaft, long enough to reachthe air outlets.2. Tap drill the air outlet holes straightthrough the shaft, intersecting the 0.375diameter hole, and tap the 0.125-27 NPTon both ends.3. The air outlet holes should be located0.375 of an inch from the end of the Hub.4. Tap a .625-18 inch hole, 0.625 inchesdeep in the end of the shaft for the RotaryAir Union.5. Install the two elbow fittings in the airoutlet holes and connect the cylinderhoses to them.6. Install the Rotary Air Union in the end ofthe shaft and use the flexible hose(supplied) to connect the air supply to theshaft (do not use rigid pipe or tubing forthis connection).45
