FEATURES/BENEFITS OF CAST ALUMINUM

Cincinnati Cast Aluminum Blowers are a smart buy now and for many years to come because aluminum is:

NON-SPARKING Cincinnati Cast Aluminum Blowers are AMCA Type B spark resistant. With the addition of a non-sparking shaft, they meet AMCA Type A requirements. See Page 5. CORROSION-FREE No painting required. Maintenance free in moist environments. LIGHTWEIGHT Aluminum is 1/3 the weight of steel and, therefore, less structural support is required. NON-TOXIC Aluminum is friendly to foods, beverages and medicines. Cast Aluminum Blowers are used in many food processing applications where cleanliness is important. STRONG Aluminum's strength is exhibited in products such as highway guard rails, truck trailers and baseball bats. In high speed blower wheels, aluminum is alloyed with magnesium and other metals for greater strength. ATTRACTIVE Aluminum's natural appearance is desirable. No other metal accepts a greater variety of finishes. It can be brushed, buffed, colored by anodizing and has excellent paint adhesion. NON-MAGNETIC Resists magnetism even in magnetic fields making it ideal in electronic applications where prevention of interference is very important. WORKABLE Aluminum can be machined by every known metal working process. This makes future modifications easier. NOT AFFECTED BY COLD Unlike many materials that become brittle when super cold, aluminum alloys can actually become stronger. Cast aluminum blowers are used in many sub-zero applications. AVAILABLE Approximately eight percent of the earth's crust contains aluminum, making it the most common metal on earth.

SUGGESTED SPECIFICATIONS FOR CAST ALUMINUM BLOWERS

Blowers shall be cast with commercial grade 319 cast aluminum, having a 3/16" minimum wall thickness. Housing halves should be attached with tapered lugs having a minimum 45 degree taper from centerline for additional strength. Inlets and outlets shall be round for convenient slip fit of duct work or hose. Blower sizes 14A and larger shall have a reversible housing that is rotatable. Blowers shall be AMCA type B spark resistant or better. Blower performance shall be derived from data as tested per AMCA Standard 210. Blower wheels with tip speeds up to 13,000 feet per minute shall be 319 cast aluminum. Blower wheels with tip speeds over 13,000 feet per minute shall be 356 aluminum with a T6 heat treatment. Wheel hub shall be an integral part of the wheel casting. Wheels shall be locked onto the motor or fan shaft with two, knurled, cup point set screws with a locking patch or nylon insert. Set screws shall be 90° ­ 120° apart with one over shaft keyway. Up to 13" diameter wheels shall have 5/16-18 set screws torqued to 165 inch pounds. Wheels over 13" in diameter shall have 3/8-16 set screws torqued to 228 inch pounds. Balancing shall be accomplished by removal of material only ­ no additional weights are to be used in the

3

balancing process. Wheel diameters up to 13" shall be statically balanced. Wheel diameters above 13" shall be dynamically balanced. Fan motor and bearing cap vibration levels shall not exceed 1.5 mils displacement at 3450 RPM. All fan bases shall be a minimum of 12 gauge steel. All motors shall be continuous duty type. Inlet or outlet flanges (if required) shall be 319 cast aluminum and shall meet ANSI bolt circle and outside diameter dimensions (see dimensions on page 21).

DANGER

All fans & blowers shown have rotating parts and pinch points. Severe personal injury can result if operated without guards. Stay away from rotating equipment unless it is disconnected from its power source. Read operating instructions.

HOW TO SELECT A CINCINNATI PB BLOWER

A word about ratings...

Thirty years ago Cincinnati Fan manufactured one size blower and one size wheel. Today we stock eight sizes of blower housings and fifty-seven wheel sizes. Four of our eight housings are each available with three different inlet sizes. By combining different housings, wheels and inlet sizes, we can offer you more standard direct drive pressure blower ratings than any other fan company in the world. Because we have so many direct drive ratings, chances are good that we can meet your requirements with a compact, cost efficient direct drive Cincinnati PB instead of a heavier, more expensive V-belt driven alternative. Your Cincinnati Fan Representative is a ratings expert who is ready to help you select precisely the right PB blower for your application.

How to use the PB Series Direct-Drive Rating Tables

If you know the static pressure and CFM required for your blower application, you can determine which PB blowers you should consider by referring to the tables on Pages 8 and 9 of this catalog. To use the tables, follow these simple directions: 1. Reading to the right, find the column heading which displays the static pressure (SP) you require. 2. Reading down that column, find the line(s) displaying the CFM rating(s) which will satisfy your requirement. 3. Follow the line(s) to the left side of the table, where you will identify the wheel(s) and the blower housing model(s) used to achieve the CFM rating(s). You may find that several ratings come close to meeting your requirements. Generally, the rating with the lowest brake horsepower requirement (BHP) is the best selection (highest efficiency, least noise). In some situations, other requirements, such as blower dimensions and/or specific inlet/outlet sizes, may override the lower horsepower rule-of-thumb. Your Cincinnati Fan Representative is available to assist you with selection and pricing information.

Some DOs and DON'Ts

DO... consider that radial blades are self-cleaning in most applications. Backward curved (BC) blades are not self-cleaning and may collect dust which can cause balance problems. DO... specify heat-resistant construction (steel wheel) for use with airstreams having temperatures exceeding 200° F (93° C). BC wheels are not available in steel.

W A R N I N G

DO NOT use a steel wheel and/or a steel blower housing in any type of environment where sparks could cause an explosion and/or fire. See Page 5. DO NOT use any blower with an unducted inlet and/or outlet without an inlet and/or outlet guard. Severe personal injury could result. See Page 7 for guard accessory.

8 STANDARD DISCHARGE POSITIONS AVAILABLE. 45° DISCHARGE POSITIONS AT ADDITIONAL CHARGE. Discharges shown are determined by viewing fan from motor or drive side.

SPARK-RESISTANT CONSTRUCTION

Type A: All parts in contact with airstream are of nonferrous material. Blind bore in wheel and brass hardware in airstream. Maximum Temperature 200°F. Type B: Standard on all PBs. Aluminum wheel and aluminum rubbing ring on motor shaft or fan shaft. Maximum Temperature up to 400°F except if with EXP motor, maximum temperature is 150°F.

WARNING

The use of aluminum or aluminum alloys in the presence of steel which has been allowed to rust requires special consideration. Research by the U.S. Bureau of Mines and others has shown that aluminum impellers rubbing on rusty steel may cause high intensity sparking. The use of the above Standard in no way implies a guarantee of safety for any level of spark resistance. Spark-resistant construction also does not protect against ignition of explosive gases caused by catastrophic failure or from any airstream material that may be present in a system.

Fan performance tables are developed using standard air which is 70°F., 29.92" barometric pressure and .075 Ibs. per cubic foot. Density changes resulting from temperature or barometric pressure variations (such as higher altitudes) must be corrected to standard conditions before selecting a fan based on standard performance data. Temperature and/or altitude conversion factors at left are used in making corrections to standard conditions.

EXAMPLE:

Select a belt driven PB blower to deliver 800 CFM at 4" SP at 200° F., and 9000' altitude. STEP 1. From the table, the conversion factor is 1.75. STEP 2. Correct static pressure is: 1.75 x 4" SP = 7" SP at standard conditions. STEP 3. Check the belt drive tables on pages 10 & 11 for 800 CFM at 7" SP. We select a model PB-12A at 3378 RPM and 1.74 BHP. STEP 4. Correct the BHP for the lighter air: 1.74 ÷ 1.75 = .99 BHP. A 11/2 HP motor will suffice at 200° F and 9000', but a 2 HP motor would be required at standard conditions. Special motor insulation may be required above 3500 feet altitude. Consult your local Cincinnati Fan sales representative.

HOUSING SIDE PLATES

On models PB-8 through PB-12A, the inlet collar and motor mounting pad are an integral part of the housing halves. Housings are rotatable but not reversible. On models PB-14A through PB-18WA, the inlet collars and motor side plates are separate castings which are bolted to the housing halves. These housings are rotatable and reversible. Note, however, BC type wheels are not reversible.

MATERIAL CONVEYING

Bulky materials such as those shown in Table 1, page 15, can be conveyed pneumatically using a Cincinnati Fan "PB" series cast aluminum pressure blower. Follow the steps below to determine the fan best suited for your application. EXAMPLE: Assume a requirement to move 900 pounds per hour of barley through 75 feet of straight, horizontal, round duct. See notes 1 & 2 below. I. Convert pounds per hour to pounds per minute: 900 lbs/hr ÷ 60 = 15 lbs/min II. Refer to Table 1, page 15. Find "barley" under material (column A) and read horizontally. Barley weighs 38 pounds per cubic foot (column B), requires 38 CFM of air per pound of material (column C) and a minimum of 5000 feet per minute conveying velocity (column D). III. Determine the minimum cubic feet per minute (CFM) requirements: 38 (from column C) x 15 (from step 1) 570 Total minimum CFM required @ 5000 ft/min conveying velocity (column D) IV. Determine the system static pressure requirements from Table 2, page 15. Read across the 5000 ft/min velocity line to the 6" duct size column. We have selected 6" duct size with 980 CFM (actual) to maintain a velocity of 5000 ft/min. The friction loss is 8.02" SP per 100' x .75 = 6.01" plus 3.5" SP suction pickup (column E, Table 1) = 9.51" total system static pressure for 75 feet of straight 6" duct. V. Check direct drive rating tables for 980 CFM at 9.51" SP at the lowest horsepower. We suggest a Model PB-14A, 14 x 31/4 wheel, 6" inlet. Interpolate 2.94 BHP. Do not use B.C. type wheels for material conveying. VI. If material being conveyed will be going through the fan, the fan BHP can be significantly increased. The approximate increase is calculated as: CFM/LB of Material x lbs/Minute =

Actual BHP = lbs/Minute of air + lbs/Minute of material x Fan BHP (2.94, Step V) lbs/Minute of air In this example: lbs/Minute of air = 980 (Actual CFM, Step IV) x .075 lbs/ft3 Standard = 73.5 Density lbs/Minute of material = 15 (See note 3) 73.5 + 15 = 88.5 = 1.20 x 2.94 = 3.53 Actual BHP Therefore: 73.5 73.5

NOTES: 1. For each 10 feet of vertical duct, add 10 feet to your total straight duct length. 2. For equivalent losses through elbows, see chart on page 9 of our Engineering Data catalog. 3. Make sure you use correct density for location of fan.

WARNING

When fans are used in material conveying applications, care must be used in their selection and location within each material conveying system. The material should be crushed, shredded or pulverized BEFORE it passes through the fan to eliminate premature fan housing, wheel and/or bearing failure which could cause severe, personal injury and/or complete system failure. Please contact a Cincinnati Fan sales engineer in your area for selection assistance for your specific application.

NOTES 1. If used with a boot kit, the temperature range of the boot is -40°F up to +250°F. 2. Standard paint may fade or deteriorate at temperatures above 200°F. 3. All models contain fiberglass media. 4. Model CSA silencers are flexible and can be carefully bent a little to go around obstructions. 5. Neoprene boot kits are available to mount CSA and GSA silencers only. Boot kits include 1 boot and 2 hose clamps. Neoprene boots are approximately 1/4 " thick. Flanges are optional for all models. 6. Model SSA silencers should use flanges for mounting but flanges are optional. 7. All GSA and SSA silencers must be independently supported. DO NOT use the blower to support the silencers. 8. Flexible hose will NOT fit over the O.D. of the inlet/outlet collars (A dimension). The inlet collars will not slide over the inlet or discharge of the blowers. 9. The GSA-7 requires a special boot kit if requested. There are no GSA-7 silencers. We use a GSA-6 with a special boot that is 6" ID on one end to connect to the GSA-6 and 7" ID on the other end to connect to PB-12A inlet or 7"duct. For a current detail drawing of the GSA-7 silencer, contact the Cincinnati Fan sales office for your location.

EXAMPLES OF CUSTOM PRODUCTS

These are just a few of the many custom blowers designed to meet the customers' exact requirements. Let us design one to yours ....

PB-14 with special motor and mounting plate for cooling traction motors on rapid transit systems. All aluminum parts were black anodized.

PB-12 with special wider housing (PB-12W) and integral discharge flange. Blower used to cool large DC motors.

PB-9 with air motor. Cast aluminum blower with non-electric motor required to handle highly volatile substances at variable flow rates.

PB-14 with continuous flange added to ensure meeting "low leakage" requirement in evacuating oil mist at 14" SP WG on discharge.
