General Fiberglass Construction Features A variety of corrosion problems plague industry today. Fans and blowers made of coated steel or metals such as stainless and monel can handle some problem areas. Please refer to the corrosion resistance table on page 8 of this bulletin. Fiberglass fans can be used in most applications where corrosive elements exist in fume and vapor form. The resistance to corrosive elements is a major advantage, but the physical properties of fiberglass equipment offer these additional advantages: Fiberglass equipment is corrosion resistant. Fiberglass equipment weighs 2% less than comparable equipment made of carbon steel. Fiberglass has an extremely high strength-to-weight ratio, stronger than steel on a per-pound basis. Dimensional stability of fiberglass is excellent. Fiberglass air moving equipment will not become brittle at low temperatures and at 0 F the laminated fiberglass will be stronger than at room temperature. Hartzell Fan, Inc. conforms to ASTM D467-97, Standard Specification for fiber-reinforced plastic fans and blowers, when optional surfacing veil, electrical grounding, and dynamic balancing to ASTM D467-97 levels, are added to the fan. The following are standard Hartzell fiberglass construction features: Corrosion resistant polyester resin, having a class l flame spread rate of 2 or less is used for all housings and propellers. All structural parts in the airstream are fiberglass and resin. All fiberglass surfaces are protected with a minimum 0-mil thickness of chemical, flame, and ultraviolet resistant resin. Fan shafts, on belt drive units, are 304 stainless steel turned, ground, polished, and keyed at both ends. Shafts are sized to operate well below critical speed. 36 stainless steel or monel shafting is available as an option at extra cost. Internal hardware (airstream), is Type 304 stainless steel. All internal hardware (airstream) is encapsulated. All external hardware (out of airstream) is zinc plated as standard. Where metal is subject to attack by the corrosive elements being handled, all metal parts can be resin-coated after assembly. Propellers are of one piece construction, die formed of individual laminations of cloth mat plus woven roving. Adjustable pitch propellers incorporate die-formed blades. Bearing covers on belt drive fans are sealed with foam gasket and bolted to the bearing base. A fiberglass and neoprene shaft seal is placed where the shaft leaves the bearing cover along with a neoprene shaft slinger between the seal and wheel on belt drive units. (Seal is not gas tight.) Bearings on belt drive units are heavy duty, deep row radial ball or double row spherical roller type self-aligning and shielded in cast iron housings. Long inner races insure even load distribution, providing a high radial and thrust load capacity. Bearings are relubricable for continuous service with lubrication tubes extended to the exterior of fan base as necessary. V-Belt Drives, when necessary, are standard and are oversized for long life and continuous duty. Fixed pitch or variable pitch drives are available. Belts are oil, heat, and static resistant type.

Selection Guide How To Use Capacity Tables. Select size, RPM and BHP for a given air delivery and pressure of an axial flow fan from the rating tables, pages 7, 9,, or 4-7. Performance ratings are based on standard air conditions, sea level 70 F and 29.92 inches barometric pressure giving an air density of.07 lbs. per cubic foot. The specific gravity of air equals.00 at these conditions. 2. If non-standard temperature or altitude is involved, correct to standard air density (see Table ). 3. For speeds above ratings consult factory. Altitude Temperature Correction Temperatures above or below 70 F at sea level (0 ft.) are read vertically between the double lines giving the proper correction factors. Altitudes above sea level at a constant 70 F temperature are read horizontally between the double lines giving those factors. Any other factors are obtained by reading down to the desired temperature, then across to the desired altitude. EXAMPLE: Assume the required performance to be 6,00 CFM,.7" SP, 7 F, and 3000 ft. altitude.. Table gives a factor of.34. 2..7" SP x.34 =.00 SP for 70 F at sea level. 3. A 36" Series 29 Direct Drive Duct Axial Fan selected from the Rating Table on page 9 for the new conditions shows 6, CFM,.00 SP at 60 RPM with 4.36 BHP. 4. Correct the horsepower and pressure in Step 3 to nonstandard performance by dividing by the factors:.00" SP /.34 =.7" SP 4.36 BHP /.34 = 3.2 BHP. Final performance of the direct drive Duct Axial fan at the assumed conditions: 6,00 CFM,.7" SP, 60 RPM, 3.2 BHP, 7 F, and 3000 ft. altitude.

Discharge Cones Ratings shown in this bulletin are for axial flow fans with inlet and outlet ducts of the same diameter as the fan. Discharge cones may be used on the duct fans to adapt to larger diameters (see Fig. A). The result is a static pressure regain. Table 2 shows the amount of additional static pressure capability, which results from using the discharge cone. Add the amount of.4 (VP VP2) to the fan's static pressure. SP 2 = SP +.4(VP VP 2 ) Figure A Figure B FAN FLOW Thus, a fan selected for 4000 FPM O.V. at 3/4" SP using a size 8"-2" cone, the static pressure capability would be raised from.70" to.97" static pressure. Regain calculations are approximate and are not part of the AMCA certified ratings. Discharge cones may also be used to transform large ducts to the fan inlet size (see Fig. B). Since these cones have gently tapered sides, the friction loss is negligible, about.08 x the difference in velocity pressures (see Table 3). If the fan is to be used with ducts smaller in diameter than the unit (see Fig. C), the difference in velocity pressure across the cone must be added to the static pressure for which the fan is used.

Duct Vaneaxial Fan (Belt Drive) The addition of a specially designed vane section to the duct axial fan changes the design configuration to a fiberglass duct vaneaxial. The addition of the vane section to the discharge side of any duct axial fan makes it perform efficiently as a low-powered vaneaxial on the upper side of its pressure curve. Near free air the guide vanes offer no advantages but beyond the mid-range, the vanes provide about 30% more static pressure with the same horsepower. The purpose of the discharge vane is two-fold: Air leaves any axial fan wheel with a rotational component to the flow that increases from free air to block-off. The rotational component (spin) is straightened by the vanes to give a smoother flow leaving the fan discharge. A large part of the rotational kinetic energy is converted to potential energy resulting in higher static pressure for the fan. Comparison of 36" Duct Axial Fans, with and without Vane Section.

SAFETY ACCESSORIES, APPLICATION AND USE WARNING The safe application and use of equipment supplied by Hartzell Fan, Inc. is the responsibility of the installer, the user, the owner, and the employer. Since the application and use of its equipment can vary greatly, Hartzell Fan, Inc. offers various product types, optional safety accessories, and sound performance data per laboratory tests. Hartzell Fan, Inc. sells its equipment with and without safety accessories, and accordingly, it can supply such safety accessories only upon receipt of an order. The need for safety accessories will frequently depend upon the type of system, fan location and operating procedures being employed. The proper protective safety accessories to meet company standards, local codes, and the requirements of the Occupational Safety and Health Act must be determined by the user since safety requirements vary depending on the location and use of the equipment. If applicable local conditions, standards, codes or OSHA rules require the addition of the safety accessories, the user should specify and obtain the required safety accessories from Hartzell Fan, Inc. and should not allow the operation of the equipment without them. Owners, employers, users and installers should read RECOMMENDED SAFETY PRACTICES FOR USERS AND INSTALLERS OF INDUSTRIAL AND COMMERCIAL FANS published by the Air Movement and Control Association International, Inc., 30 West University Drive, Arlington Heights, Illinois 60004. A copy of this publication is enclosed with each fan shipped from Hartzell Fan, Inc., and is also available upon request at Hartzell s office in Piqua, Ohio 46.

General Construction Options Abrasive/Erosive Resistant Coating HartKoate is an abrasive/erosive resistant coating developed by Hartzell Fan for application in environments where abrasive/erosive conditions may exist. HartKoate helps prevent premature deterioration of equipment in environments where uncoated fans may fail. Impact resistant HartKoate is applied to a 0-60 mil thickness suitable for temperatures to 200 F. HartKoate is particularly appropriate for use when water mist and/or abrasive particles exist in the airstream. Contact your Hartzell representative for further details concerning the application of HartKoate coating to fiberglass fans in corrosive atmospheres. Caution: The drive assembly or the periphery of the blades of a fan less than seven (7) feet above the floor or working level must be guarded to be in accordance with OSHA regulations. Hi-Cor Construction For duct, duct axial and vaneaxial fans, extra flange mounting holes are provided. All airstream surfaces exposed to the corrosive environment will be protected with a layer of Synthetic (Nexus) surfacing veil. An additional final coat of resin will be applied for extra corrosion resistance. When Hi-Cor Construction is required, the factory should be consulted concerning the corrosive environment involved. Electrostatically Grounded Fiberglass Fans For applications in which fiberglass fans are handling gas fumes that are not only corrosive but also potentially explosive, the equipment should be specially constructed to control and remove static electricity. Interior airstream surfaces can be coated with a carbon rich resin coat and grounding straps secured from the side of the housing to the fan s steel base. All that remains to effectively ground the airstream is to ground the fan base at the time of installation. ASTM D467-97 Construction (ASTM D467-97, Standard Specification for Fiber-Reinforced Plastic Fans and Blowers) For corrosive systems where ASTM construction is specified this construction option adds: synthetic veil and electrostatically conductive surface coating applied to airstream housing and impeller surfaces, special nameplates, and special final dynamic balancing to fan.
