Airflow and Sound data test parameters.
(1) Actual Airflow in CFM as measured with Horizontal Airflow on discharge side of one 15” deep transformer radiator.
(2) Nominal Sound Pressure values expressed are determined from Sound Power measurements performed in accordance with AMCA 300-08 and are based on a 2 meter measurement distance.
*Blade diameter measurements are approximate.
Krenz fan motors feature:
- Totally Enclosed Non-Ventilated (TENV) weatherproof enclosure with a shaft water slinger and condensation drain holes.
- Internal automatic reset overload protector that senses both temperature and current.
- Class F insulation with Class B temperature rise for longer motor life.
- Rated for 55°C ambient temperature.
- UL Recognized and CSA Certified.
- 1/2” NPT connection hole in integral conduit box for cable, receptacle, or conduit fittings.
- Fully sealed ball bearings permanently lubricated with heavy duty grease rated -54°C to +194°C.
- 1 Phase motors are Permanent Split Capacitor (PSC) type — without a high maintenance starting switch.
- Motors are protected with a four-step, corrosion-resistant proprietary process. Final color is ANSI 70 Light Gray as standard. Custom colors are available upon request.
Guards & Housings
Fan Model F16 features a high efficiency, venturi-type housing. All other fan models feature basket type wire guards. All fans are fully guarded on both the inlet and discharge sides of the fan to meet OSHA requirements which dictate no opening greater than 1/2”. All standard fan guards are hot dip galvanized for long life in severe conditions. 304 Stainless Steel fan guards are available on our FS line of fans.
Fan Blades
Fan models F16, F24, F25, F26, F26D and F26X feature cast-aluminum fan blades for high efficiency and quiet operation. Fan models F12 and F20 feature a heavy duty fabricated fan blade with aluminum wings and steel hubs. All fan blades are machine balanced to rigid tolerances.
