3 HOIE OF 3 WHEEL DESIGNS Three wheel designs provide the widest choice in application suitability, efficiency, sound, and cost. ll three feature the backwardinclined, non-overloading horsepower characteristic where the horsepower reaches a peak and then decreases even as flow increases. This characteristic allows maximum brake horsepower calculation and motor selection that prevents electrical system overloading even if system pressure changes. OUSTFOIL KWRD URVED PLR WHEEL DESIGN True aerodynamic airfoil-blade shape allows stable operation from wide-open to closed-off. Ideal for clean-air applications such as building ventilation with variable-air-volume system control or clean industrial-gas-handling. Dual aerodynamically designed blade surfaces provide the most efficient design of all wheel types. In addition, the coustafoil design offers a broad peak efficiency range for selection. ecause of superior efficiency, coustafoil wheels generate the lowest sound levels over a wide range of performance. Sizes and 5 available in welded aluminum only. Sizes 8 to 73 available in all-welded steel and optional aluminum and stainless steel. erodynamic, single-surface blade shape offers alternative selection points to the coustafoil for building ventilation and industrial gas-handling. ackward curved wheels also provide stable operation from wide-open to closed-off. EFFIIENY urved, single-thickness blade surface generates efficiency levels approaching the coustafoil but with alternative operating points for greater choice. SOUND The backward curved wheel offers low sound levels approaching that of the coustafoil. ONSTRUTION Sizes 8 to 73 available in all-welded steel and also optional aluminum. PERFORMNE Flat, single-thickness, backwardly inclined blades are suited to applications from clean air to those where dust and limited material is present in the airstream and airfoil shapes are not recommended due to material build-up. Peak efficiency point is on the steeply rising portion of the pressure curve and vastly superior to forward curved and radial wheel designs. Sound levels are the lowest with the most efficient fan selections.

Standard max. temp.: 300 F. Heat fan max. temp.: 650 F. PGE 6 DIRET-DRIVE RRNGEMENTS See atalog Sheet S 35, rrangement 4 fans, and ulletin 6, 4 Fans, for additional information on these models including performance, dimensions, and limitations. PPLITION ONSIDERTIONS s compared to belt-drive fan arrangements, directdrive rrangement 4 fans of all styles, where the fan wheel mounts directly onto the motor shaft, are more compact, require less maintenance, and generally have a lower first cost. However, relative to belt-drive fans, they are limited in application, size, available features, and the ability to adjust performance. Directdrive rrangement 8 fans offer much of the flexibility of belt-drive fans and are even preferred in systems that require large volumes of air and are over HP due to drive limitations. major objection to direct-drive arrangements in the past was the inability to adjust fan speed if system requirements changed. With the advent of variable frequency drives (VFDs) the speed, and therefore performance, of direct-drive fans can now be adjusted to meet varying requirements. See page 8 for additional fan-control information. Given the variety of operating speeds available, choices in wheel width, and its effect on wheel safe speed limits, the only cost-effective method for selecting today s direct-drive fans is software selection programs such as Mechanovent s Electronic atalog.

7 ELT-DRIVE RRNGEMENTS See ulletin 05, General Purpose Packaged Fans, for additional information on rrangement 0 models including performance, dimensions, and limitations. PPLITION ONSIDERTIONS s compared to direct-drive fan arrangements, beltdrive fans, where the fan wheel is supported by a shaft and bearings and driven by belts, allow for a wider range of sizes and applications, and offer a greater selection of accessories and modifications. However, relative to direct-drive fans, they have a larger footprint for a given fan size and have a higher first cost. Without additional controls, belt-drive fan performance can be easily altered in the field by changing sheaves and belts. ecause of the numerous choices available between belt-drive and direct-drive arrangements, it is recommended that you consult your Mechanovent representative for selection guidelines. SIZE/RRNGEMENT VILILITY Wheel coustafoil PLR rrangement Wheel diameter in inches RRNGEMENT Overhung wheel keeps bearings out of airstream. Motor mounts independently from fan. Greatest flexibility. Standard max. temp.: 300 F.* Heat fan max. temp.: 650 F.* RRNGEMENT 3 Wheel supported between bearings is compact and suitable for clean, dry-air service. Max. temperature: 0 F. RRNGEMENT 9 Similar to rrangement but with motor mounted on side of fan pedestal reducing overall size and field-installation costs. Standard max. temp.: 300 F.* Heat fan max. temp.: 650 F.* RRNGEMENT 0 ompact, packaged design with motor mounted within the fan pedestal. Minimum field installation labor required. Standard max. temp.: 00 F.* Heat fan max. temp.: 650 F.* *Limit for Sizes and 5 fans with coustafoil wheels is 00 F.; heat-fan construction not available. V-ELT DRIVES In the lower horsepower ranges, V-belt drive selection is relatively simple, but as horsepower requirements increase, V-belt drive selection becomes more complicated and requires more consideration of the drive s effects on fan and motor bearings. few general recommendations to remember are: motors are not generally recommended for belt-drive above 0 HP motors are not generally recommended for belt-drive above 300 HP. 3. When motors 00 HP and larger are to be used with belt-drive fans, Mechanovent requires that the motor manufacturer: a. Recommend the minimum diameter motor sheave that may be used. b. Recommend the maximum motor-sheave width that may be used. With the above information from the motor manufacturer, the drive may be selected. PGE 7

8 FN ENGINEERING ND SELETION GENERL Fans are an integral part of the systems in which they are applied. s such, Mechanovent sales representatives work closely with design engineers in assessing requirements and meeting critical performance and dimensional specifications. ecause of the wide variety of choices available, it is recommended that selection be made using Mechanovent s Electronic atalog software and that a Mechanovent sales representative assist in optimizing the final selection. WHEEL SPEED VS. WIDTH major component in the determination of wheel maximum safe speed is blade strength. Narrower wheels are inherently stronger, permitting higher wheel maximum safe speeds. Using a variety of engineering tools such as a finite element analysis, Mechanovent can now provide performance selections previously unavailable. For example, the direct-drive performance curves shown here illustrate maximum performance capabilities with full-width wheels [solid lines] and maximum performance capabilities with narrow-width wheels [dotted lines] at 70 F. Note that the pressure generating capability approximately doubles. Final selection of direct-drive fans can only be optimized using Mechanovent Electronic atalog software. SIZE 30 LSS II FN PERFORMNE SP [in. WG] coustafoil coustafoil PLR PLR FULL-WIDTH URVES NRROW-WIDTH URVES HET FNS Fans handling hot airstreams must be kept in operation after system shutdown until the airstream cools below 00 F. to prevent damage to the fan. The fan wheel or shaft might otherwise distort due to heat-soaking. The shaft cooler is only effective while rotating. urners should be located so that the air is thoroughly mixed before entering the fan inlet. Improper placement could cause hot spots on the fan wheel which exceed maximum design temperatures. ontact Mechanovent when the application involves temperature changes greater then 0 F per minute. Refer to the selection example on page 9 for the effect of temperature on the maximum safe speed of wheels and the temperature derate factors in hart I. PITY ONTROL The rising cost of energy requires that air-handling systems be operated efficiently at less than maximum design airflow. The high efficiency and inherent stability of the coustafoil wheel is particularly wellsuited to variable airflow systems. The coustafoil wheel design ensures not only maximum operating efficiency at design but also at reduced airflow regardless of the control method applied. This higher efficiency allows quieter operation throughout the modulation range. Mechanovent s nationwide network of trained sales representatives is familiar with each of these control alternatives and can offer further assistance in selecting the best control for a particular application. INLET-VNE DMPER ONTROL Inlet-vane dampers affect the fan s output by spinning the air in the direction of wheel rotation. With this prespin, the wheel cannot develop its full output, yielding a reduced at reduced horsepower. Each damper setting creates new pressure and horsepower curves. With inlet-vane dampers, reduced airflow always results in reduced horsepower. VRILE FREQUENY MOTOR SPEED ONTROL Variable frequency motor speed controllers provide energy savings by directly controlling fan speed. From the fan laws, varies directly with the change in fan speed and horsepower varies by the change in fan speed cubed. For example, a 0% reduction in fan speed yields a 0% reduction in airflow and a 49% reduction in. ontrollers must have lockouts to prevent operation beyond the maximum safe speed of the fan. % PRESSURE % INPUT POWER % PRESSURE % INPUT POWER % VOLUME % VOLUME % VOLUME % VOLUME PGE 8

9 HOW TO USE PERFORMNE TLES For a given fan size, wheel design,, and static pressure, performance tables can be used to obtain outlet velocity, fan, and. If capacities are at conditions other 70 F., sea level, or standard density [.075 lb./cu.ft.], correction factors must be applied to static pressure and. PROEDURES STEPS EXMPLE: fan is required for 3,000 at 4 WG at 600 F. and sea level. If conditions other than standard are involved, correct static pressure for actual altitude and temperature using harts II and III. hart II gives a.00 factor for 600 F. orrected SP is 4 WG x.00 = 8 WG at 70 F. Select fan from performance tables for 3,000 at 8 WG. Select size, wheel type,, and of fan from performance table. Size 30 with coustafoil wheel is selected for 3,000 at 8 WG at 650 and 0.5. heck maximum safe speed of fan at operating temperature as shown in the performance tables and hart I. From the performance table and hart I, the maximum safe speed of a Size 30 fan with coustafoil wheel at 600 F. is 660 [805 x.9]. Fan is satisfactory for operation at 600 F. Determine actual performance at operating conditions by correcting SP and. PERFORMNE ORRETION FTORS Fan performance is based on actual feet per minute [] at the fan inlet at standard density [.075 lbs./ft. 3 ] and static pressure at the fan outlet. Static pressure capabilities are shown in inches water gauge [ WG]. ir-density corrections are necessary for proper selection when air density varies from the standard.075 lbs./ft. 3 at 70 F. at sea level. Multiply the required static pressure at operating conditions by the appropriate factors in harts II and III to obtain the corrected static pressure for standard conditions. Pressure and will be reduced at conditions by the inverse of these factors. Multiply one factor by the other if temperature and altitude are non-standard. For example: if the installation is located at an altitude of 4000 feet and the gas temperature is 300 F. the correction factor is.66 [.6 x.43]. Temperature and altitude correction is made automatically using Mechanovent s Electronic atalog software. MXIMUM SFE SPEED INFORMTION Each performance table on pages 0-7 includes the maximum safe speed of the standard wheel at 70 F. Fan operation at temperatures above 70 F. primarily affects the strength of rotating components, which declines as temperature increases. When alloy construction is specified or when temperatures are involved, multiply the appropriate safe operating speed shown in the performance table by the factor shown in hart I. Note that Sizes and 5 coustafoil wheels are aluminum as standard. lso that the maximum safe speeds apply only to wheels operated at or below 70 F. and are free of material build-up, corrosion, or wear. See discussion on page 8 regarding direct-drive fans and maximum safe wheel speeds for wheels that are narrow-width.
