Fiberglass Axial Flow Fans Models FDP FRV FBD TFBD VTFBD Medium Pressure Vaneaxial Model VTFBD & Vane Section Aerovent axial flow FRP (Fiberglass Reinforced Plastic) fans are built in a variety of sizes and designs as shown in this catalog. Aerovent also builds an FRP single-width centrifugal model (shown in Catalog 745), an FRP high-pressure blower (shown in Catalog 950), and an FRP in-line centrifugal model (shown in Catalog 60). Corrosion resistance is the primary consideration when selecting a fiberglass fan. The standard resin used is selected for resistance to a large variety of corrosive agents. When a corrosion resistant fan is required to withstand chemicals which attack glass or polyester resin, special construction features can be supplied. For reference, a Corrosion Resistance Guide is included on page 5. All models shown in this catalog have housings and fan wheels made of continuous glass lay-up using a combination of fabric-woven roving and mat. Tubeaxial Model FBD Belt Driven Models The bearing supports are integral with the housing and motor support flanges. The bearing bases are reinforced with cross-strutting, constructed out of glass and resin. Fan shafts are stainless steel. Bearing covers are sealed, but still allow for access to the bearings. Grease lines extend to outside the housing for ease of maintenance. The motor is located outside the airstream, with protective motor covers standard on all models. Advantages of Fiberglass Fans Superior corrosion resistance to gases and vapors. Lower maintenance costs. More economical than stainless steel construction. Lighter weight than steel. Model FBD Type FG Tubeaxial The Model FBD is the standard Aerovent FRP belt driven tubeaxial with many years of proven success in numerous and varied applications. It is furnished with the efficient semi-pressure type FG 7-bladed propeller on sizes up to 48 and the type FG 6-bladed propeller on sizes 54 and 60. For the medium performance range requirements, these fans generally run at a slightly higher speed than the type TF models, but have an economical advantage in many applications. Performance data for the Model FBD is shown on pages 7 and 8. Sizes 4" to 60" wheel diameters Performance Airflow to 5,900 CFM Static pressure to.5 inches w.g. 2 AEROVENT CATALOG 85

Construction Features Shaft The 6 stainless steel step shaft is machined and keyed with the end drilled and tapped. The propeller is held tightly against the shaft shoulder by a stainless steel retainer bolt and washer in the end of the shaft. Shaft Seal The bearing and shaft enclosures have covers that are sealed into place with an inert silicone sealant. The shaft is fitted with a rotating elastomeric seal that rides against a heavy Teflon wear plate. Bearings The bearings are sealed pillow block type with grease lines extending to the outside of the fan housing for ease of maintenance. The bearings, shaft and drive are enclosed to protect them from airstream contaminants. Motor Base A steel motor base with slide rail arrangement for belt adjustment is bolted between wide gussets integral with the flanges of the fan housing. The standard motor cover is made of fiberglass reinforced plastic and extends over the entire base, motor and drive assembly. Drives All belts and sheaves used on Aerovent fiberglass fans are manufactured by Browning and are selected to provide additional allowances of. to 2 times the normal satisfactory capacity. Corrosion Resistant All airstream parts of fiberglass reinforced plastic have resistance to most chemicals. The fiberglass propellers are standard with vinyl ester resin (optional on housing). See Corrosion Resistance Guide on page 5. Propeller The type TF and FG fan propellers are constructed using a resin transfer method (RTM). Glass cloth is cut to various template sizes to form laminations which are fitted into a mold. Glass is impregnated with vinyl ester in a low-pressure injection process. The fan wheel is cured under pressure in the mold, forming a monolithic structure. Housing The fan housing is polyester resin reinforced with cloth and mat with integral flanges. The bearing, base and drive enclosure is supported by gussets interlocked into and taped to the outer housing. These structural parts are all of laminated glass and resin. Product Finish All fiberglass parts are coated inside and outside with resin (with UV inhibitor), approximately 0 mils in thickness, to seal and provide protection from ultraviolet light. This results in a smooth finish. All steel parts are finished with light gray epoxy paint. Vane Section The vane section is of all laminated glass and resin construction with curved guide vanes interconnected with an inner and outer shell. Fire Retardant Resin Optional fire retardant resin reduces the resin s tendency to burn, attaining a flame spread rating of 25 or less. Optional Construction Special Fiberglass Materials Please contact the factory to ensure a suitable material is selected for the specific application. Vinyl Ester Provides increased corrosion resistance to stronger acids, chlorine and oxidizing agents. For use in industrial applications such as chemical and water treatment plants, and commercial applications where urban or salt air corrosion exists. Fiberglass propellers are standard with vinyl ester resin (optional on housing). Surface Veil Produces a smooth reinforced final surface with greater corrosion resistance and contains UV inhibitor. Spark Resistant Construction Spark resistant construction for fiberglass fans is recommended when the fan is handling explosive fumes. Although fiberglass is a non-sparking material, it can build and retain a static charge that can be potentially hazardous. With spark resistant construction, the fan is statically grounded by graphite impregnation to reduce a static charge build-up. 4 AEROVENT CATALOG 85

Design & Construction For roof mounted exhaust applications, the Model FBD tubeaxial fan can be converted into a roof ventilator (Model FRV) with the addition of a fiberglass stack cap and curb base. Performance data for the Model FRV is shown on page 5. For Model TFBD or VTFBD roof ventilator assembly data, add 8" for stack cap loss to the standard tubeaxial/ vaneaxial performance ratings, or contact factory. Note: A minimum flow rate is required to fully open the stack cap damper blades (700 FPM outlet velocity) Max 00 FPM. Model FRV Roof Ventilator Construction Features The stack cap windband section is constructed from a one-piece mold with drain channels and drain holes to allow water to flow out. The stack cap damper blades are reinforced with a turned-down flange at the blade edge that seals the fan discharge when the fan is shut off. The stack cap damper rods are constructed of fiberglass with PVC bearings to offer a long service life. The curb base is constructed from a one-piece mold that offers a no-seam base, thus eliminating the chance of water leakage. The curb base is reinforced to offer additional support for a long service life to prevent sag, cracking, etc. Stack Caps Designed with backdraft dampers that protect the interior of the building from precipitation when the fan is shut off. Motor Covers Designed to protect the motor and drive parts from the weather. Curb Bases Designed for mounting vertical fans on roof curbs and to provide easy installation of the unit. Installing Fiberglass Reinforced Plastic (FRP) Fans The installation of FRP vaneaxial and tubeaxial fans requires some special considerations. The material is very strong, but it is more flexible than steel; therefore, large fans with heavy motors should not be expected to support themselves by the flange mounting alone. A fan mounted in the vertical position should not be mounted to support a heavy stack without some reinforcement. It is usually satisfactory to mount fans having motors up to HP by the flanges alone. Match drill the flanges with the mating duct flange, using eight equally spaced holes, 7 6" diameter to accept a 8" bolt when bolting the fan to ductwork. Use a large washer under the head and nut to increase the bearing area, and do not tighten these to the point of crushing the flange. If the fan has a 5 HP or larger motor, it is good practice to attach a support leg or hanger rod to the outer edge of the motor base plate to take some of the weight. If the fan is to be mounted on the roof with a high discharge stack, brace the stack just above the fan so that not all of the stack weight is carried on the fan mounting flanges. Accessibility for service and cleaning is a very important consideration in installing an FRP fan. They should be mounted for easy removal for cleaning and service. A removable section of duct on either side of the fan may be installed to provide access. Access doors are available as an option.
