4 Fiberglass Exhauster Construction Features A variety of corrosion problems plague industry today. s 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 3 of this bulletin. Fiberglass centrifugal blowers 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 25% 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, Inc. conforms to ASTM D , Standard Specification for fiber-reinforced plastic fans and blowers, when optional surfacing veil, electrical grounding, and dynamic balancing to ASTM D 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 25 or less is used for all housings. Vinylester resin having a Class l flame spread rate of 25 or less is used for all wheels. Structural parts in the airstream are either fiberglass resin or epoxy coated stainless steel. All fiberglass surfaces are protected with a minimum 10-mil thickness of chemicals, flame, and ultraviolet resistant resin. Shafts are turned, ground, polished, keyed at both ends, and fiberglass enclosed in the airstream on belt drive units. On direct drive units shafts are stainless steel. Shafts are sized to operate well below critical speed. 304 or 316 stainless steel or monel shafting is available as an option on belt drive units at an extra cost. Internal hardware (airstream) is Type 304 stainless steel. All internal hardware (out of airstream) is zinc plated as standard. A fiberglass and neoprene shaft seal is placed where the shaft leaves the housing. Series 82 & 83 Downblast Series 87 & 88 Upblast Fiberglass Exhausters 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 ensure even load distribution, providing a high radial and thrust load capacity. Bearings are relubricable. V-Belt Drives are oversized for long life and continuous duty as standard. Fixed pitch or variable pitch drives are available upon request. Belts are oil, heat, and static resistant type. Type FE Wheel Type FE Wheel Features The Type FE wheel offers a slight enhancement to the Type FA wheel which is unique in the fan and blower industry. It is available in diameters from 12" to 60" in both clockwise and counter-clockwise rotations. The wheel is airfoil design and solid fiberglass die formed and coated with Dow Derakane 510-A corrosion resistant vinylester resin. The manufactured wheel is a single piece, removed from the pattern whole. This ensures each wheel is aerodynamically identical and provides reliable repeatable performance without the variability of hand made and taped components. The design is the result of a substantial investment in research, development, tooling, and manufacturing methods by Hartzell, Inc. The type FE wheel is highly efficient, with tapered inlet side and airfoil blades. It has non-overloading horsepower characteristic curve. When used in conjunction with a precision inlet cone it efficiently moves large volumes of air at high pressures with low noise characteristics at low RPM. The fiberglass resin has a Class I flame spread rate of 25 or less. The wheel is electronically statically and dynamically balanced to the requirements of Application Category BV-3 of AMCA ANSI Std and receives an Operational Test and Inspection before shipment. Special constructions are available for abrasive environments or extremely corrosive environments. 4

5 Fiberglass Exhausters The Hartzell Fiberglass Exhausters provide a lower profile roof or wall exhaust solution in a corrosive environment in an upblast or downblast configuration. Applications Paint and chemical storage facilities, gas transmission pump houses, battery charging facilities, and wastewater/odor control pumping stations Sizes Available in sizes 12, 15, 18, 24, 30, 36, and 40. FRP Materials The dome ventilators consist of a fiberglass housing, fiberglass curb cap, and fiberglass motor cover all constructed of Ashland 693 resin. The solid fiberglass wheel is molded with Dow Derakane 510-A corrosion resistant vinylester resin. Unit has a formed fiberglass venturi inlet and outlet. All airstream hardware is 304 SS. Wheel These exhausters utilize the FE wheel, the FA wheel slight modified to improve performance in an exhauster application. The manufactured wheel is a single piece and removed from the pattern whole. This ensures that each wheel is aerodynamically identical and provides reliable, repeatable performance without the variability of hand made and taped components. It is highly efficient with tapered inlet side and airfoil blades. Temperature Limitations Suitable for temperatures up to 200 F. Motor Direct drive motors standard with extended shaft; belt drive motors are standard t-frame. Motor and drive components are protected from the airstream and internal isolation to minimize vibration. They are available in single or three phase, with two-speed and explosion proof motors available on some models. Options and Accessories See Page 11.
