Page 19: Figure 3-2 - Water Quality Requirements
TYPE OF SERVICE – The blower can be operated in either pressure or vacuum service. Pressure – Never operate the blower above the maximum pressure shown in FIGURE 3-1. Excessive pressure may cause overheating and blower failure, it is therefore most important to have an accurate pressure gauge in the discharge line as close to the blower discharge as possible. -
Page 20: Figure 3-3 - Liquid Rate
If the injection water supply is allowed to run after blower shutdown, both the blower and adjacent discharge piping may fill with water and present a serious overload problem at the next attempted start. To prevent this, it is strongly recommended that an electric solenoid valve (normally open) be installed at the lowest point in the discharge elbow and/or connecting piping. -

Page 40: Figure 7-5 - Angular Contact Bearing Assembly
FIGURE 7- 5 – ANGULAR CONTACT BEARING FIGURE 7-6 ASSEMBLY The CycloBlower is designed for no metal-to-metal contact with parts within the housing. To achieve this, some preliminary measurements are necessary before completing the assembly. The first set of measurements are used to determine the shaft shim set thickness necessary for positioning the rotors in the housing to give the required clearance between the end of the rotors and the carrier face at the discharge end. -
Page 41: Figure 7-7 - Discharge End Bearing Carrier
EXAMPLE FOR 9CDL18 BLOWER: Micrometer reading of .015” plus .009” discharge end clearance, FIGURE 7-8, plus .002” crush gives shaft shim set thickness of .026”. Figure shaft shim set for each rotor and record measurements which will be used later in the assembly under Steps 15 and 16. FIGURE 7-7 The second set of measurements is used to determine total end clearance. -
Page 42: Figure 7-11 - Discharge Opening & Dowel Pins
FIGURE 7-11 FIGURE 7-12 11. Coat the I.D. of the shaft seals in the discharge end bearing carrier with “Moly” type grease. Remove bearings from the carrier. Tag bearings so they will be reassembled in the same bearing bore from which the measurement was made. Match the cavity of the carrier, FIGURE 7-7, with the discharge opening of the housing FIGURE 7-11, and lower the carrier, suspended plumb, in place on the housing. -
Page 43: Figure 7-13 - Seal Installation Guide
14. Using the correct installation tool, press the seal down into the bore. Verify that the seal face is below the bearing spacer face. Repeat for other shaft. 15. With micrometer, FIGURE 7-14, measure the thickness of shaft shim sets (22, 23) established in Step 5 thru 8. -
