2 Industrial Fans odels - Class 22 & 32 HO I HR I I HW I HP The H Series Industrial Fans manufactured by Aerovent are well suited for installations involving exhaust, material conveying, pollution control, air circulation, and a variety of other industrial applications. The typical performance characteristics for different wheels offered in H Series fans are illustrated below. It should be noted that all wheels essentially have overloading characteristic type brake horsepower curves; however, odel wheels have this to a lesser degree than other types. HO Arrangement 8 Aerovent certifies that the H Series odel HO/HR// HW fans shown herein are licensed to bear the ACA Seal. The ratings shown are based on tests and procedures performed in accordance with ACA Publication 211 and comply with the requirements of the ACA Certified Ratings Program. While the general pressure characteristic curve is similar for all H Series wheels, the type wheel is considerably more efficient than other H Series wheels. Therefore, the wheel is the first choice where brake horsepower savings are important, but the wheel is limited to handling relatively clean air or gases. Efficiency is critical in most applications, and it is important that the fan size is selected so that it will operate at or near its maximum efficiency point. This is particularly important with the units that have lower efficiency in general, such as the HO and HW wheels. Aerovent offers a complete series of wheels to meet the needs of most industrial process and material handling applications. Each wheel is statically and dynamically balanced on electronic equipment prior to being assembled in the fan. In addition, each unit is run at or near operating speed after assembly and the balance is fine-tuned as a complete assembly.

H Series fan housings are constructed in all usual arrangements and conform to ACA Standard (rive Arrangements for Centrifugal Fans). The fan sizes and wheel diameters conform to ACA Standard (Sizes for Industrial Centrifugal Fans). ACA does not have a standard for industrial fans designating class of operation. Aerovent offers three basic categories, based on performance, of industrial fans. Two of the categories are shown in this catalog: 1. Class 22 suitable for applications involving performance to approximately 22" SP; and 2. Class 32 for performance to 32" SP. Performances shown in the tables on pages 11 through 29 are shown in regular face type to indicate Class 22 fans and in bold face type to indicate Class 32 fans. A separate supplemental catalog (Catalog 911) shows the third category: Class 45 high pressure fans capable of reaching performance of approximately 45" SP. 2 Aerovent Catalog 710

3 HO Industrial Radial Paddle Wheel: The open type radial paddle wheel design is extremely rugged using heavy-gauge steel components which are jig assembled for accuracy and consistency. All wheels are welded with care to insure the maximum in strength and reliability. HO wheels are suitable for general handling of coarse, sticky, heavy, and/or abrasive materials. Wheel Types HR Industrial Radial Paddle Wheel: The HR wheel is similar to the HO, with the addition of end rings. HR construction is standard on size 926 and larger Class 32 fans. HR wheels are suitable for general handling of coarse, sticky, heavy, and/or abrasive materials. Industrial Radial Air Handling Wheel: The wheel is a more efficient type of wheel and is used when handling relatively clean air, fumes, vapor exhaust, and air with a light contaminant. The wheel is constructed with heavy-gauge blades welded to both backplate and front ring. HW Industrial Radial Backplate Wool Wheel: The HW wheel is constructed to prevent paper shreddings, threads from buffing system exhaust, and other similar matter from hanging up on and wrapping around the spiders and blades. Applications include long, stringy or fibrous materials. HO / HR HW HP HP Industrial Radial Paper Handling Wheel: This modified HW wheel features trapezoidal gussets for the extra rugged construction necessary when handling corrugated paper trims, fibrous material, metal trim, and other high impact loading material. A paper deflector cone over the face of the hub helps prevent wrapping of paper around the hub or leading edge of the blades. All HP fans are supplied with bearing stop blocks and a relieved inlet transition. The relieved inlet transition smooths the flow of paper trim and similar material through the fan. Breaker tabs are offered as an option on the relieved inlet transition to assist in the breakup of material. ue to the nature of the applications, HP Class 32 construction is limited to 22" SP and HP Class 45 construction is limited to 32" SP. Use HW performance tables for HP fans. The HP fan is not ACA licensed. Rotatable and Reversible Configuration The table on page 2 identifies fans that are rotatable or reversible. A fan available in a rotatable configuration indicates that the fan can be rotated in the field to any of the standard discharge locations. A fan available in a reversible configuration indicates that the wheel rotation can be changed in the field from a clockwise to a counterclockwise direction or vice versa. This is possible only on rotatable housings and requires the wheel housing to be removed and reversed. Consult the factory before reversing a fan. See the chart on page 5 for specific configurations and their designations.

4 Arrangements Arrangement 1 Arrangement 1 fans are available in either direct drive (see Arrangement 8 below), or belt driven installations. The belt driven configuration allows the motor to be mounted in any of the four standard motor positions shown on page 5. The choice of a belt driven installation provides greater performance flexibility with the use of belts and sheaves of differing sizes. Arrangement 8 Arrangement 8 fans use a fan shaft and motor direct coupled via a flexible coupling. The integral motor subbase is fabricated of heavy gauge steel and securely reinforced for rigidity. Aerovent can supply wheels in a variety of diameters and differing widths to give the greatest efficiency for any given application. If desired, an Arrangement 1 fan can be set up for direct drive. This requires a concrete motor pedestal to be built in the field. Arrangement 9 Arrangement 9 fans include a motor slide base mounted on the side of the motor pedestal. The motor and drive can be installed at the factory or field installed. Class 22 fans up to size 929 are offered in Arrangements 9A (shorter pedestal for small motors) and 9B (longer pedestals for larger motors). aximum motor frame sizes for Arrangement 9A and 9B are listed in the table on page 5. Unless otherwise specified, the motor will be installed on the left (L) side of the pedestal on CW fans and on the right (R) side on CCW fans. Arrangement 9F Arrangement 9F (floor mount) fans are recommended when a packaged unit is desired, but required motors are too large to be mounted on the side of the bearing pedestal. In this arrangement, the base is extended to facilitate motor mounting in a horizontal position similar to an Arrangement 1 fan. This arrangement is preferred over Arrangement 9 when larger horsepower motors are being employed. Unless otherwise specified, the motor will be installed on the left (L) side of the pedestal on CW fans and on the right (R) side on CCW fans. Arrangement 9F requires a separate subbase when vibration isolation is required. Arrangement 10 Arrangement 10 fans are suitable for roof or outdoor installations. A weather cover, as shown, provides complete weather protection for motor, shaft, bearings, and drives. This arrangement is limited to Class 22, sizes 905 through 919. aximum motor sizes allowable in this arrangement are listed in the table on page 5. Larger fan sizes in this arrangement, or larger motor sizes for smaller fans, may be available on special request from the factory. All usual accessories are available in this arrangement. 4 Aerovent Catalog 710

6 Accessories Access oors Bolted and quick-opening access doors are available for easy access to the fan interior for inspection or cleaning. All access doors are gasketed and are constructed with either evenly-spaced studs or heavy duty hinges and handle-type nuts which require no tools to open. Raised bolted access doors are available for use where insulation is being applied to the outside of the fan. Quick-Open Access oor Bolted Access oor Raised Bolted Access oor Inlet Bell On installations with an open inlet (no ductwork at the inlet of the fan), a streamlining inlet bell is required to achieve the catalog performance. Opposed Blade Parallel Blade Outlet ampers Inlet Bell Outlet ampers ue to the performance characteristics of industrial fans, a damper on the outlet of the fan is a very efficient way to control volume. An outlet damper can be used to reduce the power consumption of a fan operating at high temperatures or a fan operating in low density gas streams. uring a cold startup, the outlet damper begins in a closed position and is opened gradually as the fan reaches operating temperature. This allows for the use of a smaller motor sufficient to handle the duty at higher temperatures. Aerovent offers two basic styles of outlet dampers: Type 1 is made of single surface blades suitable for clean air applications, pressures to 25" SP and temperatures to 300 F; Type 2 has double surface airfoil blades for abrasive type applications, pressures to 40" SP and temperatures to 800 F. Both types of dampers are available with opposed or parallel blades and can be manually operated or set up for automatic operation. External Inlet Vanes Inlet Vanes For reduced flow situations with relatively clean air, inlet vane type dampers are available to maintain fan efficiency. The inlet vanes are external type attached to the inlet of the fan. Standard construction inlet vanes are suitable in applications up to 300 F. High temperature inlet vanes are also available for temperatures up to 600 F Aerovent, inneapolis, N. All rights reserved.

7 Accessories Inlet Boxes An inlet box is designed to minimize pressure drop and airflow losses. Inlet boxes are recommended for applications where uniform flow is difficult to obtain due to limited space or where the air must enter the fan at an angle. Inlet boxes can be either detachable or integral to the fan. This option is available with an inlet box damper to provide increased airflow control. rains A pipe coupling can be welded to the lowest point in the housing scroll to allow wash water or condensation to drain. Inlet Box rain Shaft Coolers Where high temperatures are encountered, the aluminum shaft cooler is recommended for dissipating heat and protecting bearings from the high temperature atmosphere. Shaft Seals The standard shaft seal is a non-asbestos type, sandwiched between two plates and the fan housing, providing a seal for most materials being handled. A variety of special seals, including mechanical type stuffing boxes, is available for gas-tight applications requiring more positive protection. Shaft Seal & Saft Cooler Spark Resistant Construction Three fan constructions are available for spark resistance. The materials used in the construction of these fans minimize the potential of sparks being generated by striking or rubbing components within the airstream. Type A All parts of the fan in contact with the air or gas being handled are made of nonferrous material. (Aluminum wheel construction is limited to 250 F.) Type B The fan has an entirely nonferrous wheel and nonferrous ring around the opening through which the shaft passes. (Aluminum wheel construction is limited to 250 F.) Type C The fan is constructed so that a shift of the wheel or shaft will not permit two ferrous parts of the fan to rub or strike. In applications where aluminum is not suitable, wheels constructed of monel can be furnished for temperatures up to 1000 F. Notes: 1. The user must electrically ground the fan. 2. Standard spark resistant alloy is aluminum. 3. Bearings must not be placed in the air or gas stream. Other Accessories A large number of other appurtenances and accessories is available from Aerovent, including: Belt guards standard and OS type Split housings Shaft and bearing guards Couplings and coupling guards Wheel liners Scroll liners Weather covers Inlet and outlet screen Special material construction (stainless steel, onel, etc.) Special coatings and finishes Insulation pins Abrasion resistant construction Common bases with and without isolation Breaker tabs are offered on HP fans as an option on the relieved inlet transition. These tabs assist in the breakup of material as it enters the fan. 7
