Hartzell Series 34 Fiberglass Belt Drive Duct Fan – 12″

The Series 34 Fiberglass Belt Drive Duct Fan is manufactured by Hartzell Air Movement and is completely assembled and ready to install upon arrival. Series 34 fans can be mounted in any position, from horizontal to vertical.

The propeller is a 6 bladed airfoil design, constructed of a single piece of solid fiberglass with an aluminum insert securely molded to the hub. The hub is assembled using Type 304 stainless bolts and mounted on the fan shaft with a tapered bushing. The fiberglass propellers, fan housing and components can be used in temperatures of up to 200° F.

The fan housing is constructed of solid fiberglass, including the flanges, which come with drilled mounting holes. Fan construction conforms to ASTM Standard D4167 for fiber reinforced fans and blowers. The fan shaft is made of Type 304 stainless steel, with heavy duty bearings located in a sealed drive compartment to prevent the entry of corrosive elements. The fan bearings are built for continuous service of at least an L10 life of 50,000 hours.

The fan assembly is dynamically balanced at the Hartzell factory prior to shipping and the fans are balanced to conform with the American National Standards Institute, Std. S2.19-1989 “Balance Quality of Rotating Rigid Bodies,” Grade G6.3. Fans are manufactured in accordance with Hartzell’s standard quality assurance procedures. Fan performance is based on tests conducted in Hartzell’s AMCA accredited laboratory in accordance with the latest revision of AMCA Standard 210 for air performance and AMCA Standard 300 for sound performance.
