3 INTRODUCTION Zephyr Cabinet Fans PennBarry Zephyr series ZC/ZCC belt drive cabinet fans are general purpose duct blowers. These versatile, quiet operating air movers provide economical, convenient and effective ventilation in ducted systems. They are also used extensively in heating and cooling systems. Four sizes cover an air capacity range up to ZC units are sized with space saving in mind and furnished with inlet and outlet connecting flanges and side access panels as standard. ZCC units are dual units placed side by side to maximize airflow and minimize overall footprint. Optional accessories include a duct mounted filter assembly. Model: ZC Static pressure up to 1.5 wg. Belt Drive - Flow capacity up to 6,350 Model: ZCC Static pressure up to 1.5 wg. Belt Drive - Flow capacity up to 12,700 CERTIFICATIONS & LISTINGS AMCA Certifications PennBarry certifies that the Zephyr ZC and ZCC models shown herein are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Standard 211 and comply with the requirements of the AMCA Certified Ratings Program. UL and cul Certification Zephyr cabinet fans (models ZC and ZCC) carry the UL label (ZACT / ZACT7), File #E FEATURES & BENEFITS Internal Motor and Drive Assembly The motor and drive assembly are located inside of the unit for safety. This design also cools the motor so the unit will run more efficiently. Ball Bearing Motor Zephyr Cabinet fans utilize ball bearing motors for durability and long life. Easy Access Side Panels Zephyr Cabinet fans come with dual side panels. These panels are easily removable which allows for installation flexibility. Blower Shaft Ball Bearings The blower shaft rides on ball bearings for quiet operation. Application Versatility Zephyr Cabinet fans can be used for supply or exhaust. Model ZCC Twin Unit The twin assembly doubles the capacity of a single unit for the same static pressure with identical RPM. Two similar motors are used which enables the flexibility of independent operation when desired. Moving Your Way 3

4 OPTIONS & ACCESSORIES Acoustically Insulated Housing Optional insulation to line housing for acoustic sensitive applications. Vibration Isolation Zephyr Cabinets fans can be supplied with vibration hangers. Vibration hangers allow the fan to be isolated from the building structure which prevents any building resonance from being transmitted to the fan housing. Guards Zephyr Cabinet fans can be supplied with inlet and outlet guards for safety. Internal Wiring Standard wiring is NEMA 1 rated. NEMA 3R wiring is available as an optional upgrade. Safety Disconnect Switch Safety disconnect switches are available to allow positive electrical shut-off and safety. Switches are factory mounted when factory wiring is requested. Wiring is only run from the motor to the junction box. (Factory wiring of explosion proof applications is not available.) A wide range of Nema rated enclosures with disconnect switches are available for indoor, outdoor, and explosion proof installations. Disconnects are to be field wired by a licensed electrician. ZF Filter Series ZF filters are designed for compatibility with Zephyr series ZC cabinet fans. ZF filters can be close-coupled to ZC unit inlets or installed remote to the ZC in the system duct work. The compact design and ease of maintenance also make ZF filters an ideal choice as a standard duct filter. The filter media can be easily cleaned and is washable with plain soap and water. The pull-out drawer action provides quick and easy access. One filter is required for Model ZC and two filters for Model ZCC.

5 TYPICAL APPLICATIONS Zephyr ZC and ZCC Cabinet fan units are versatile in application. They may be used in ventilation, recirculation, and air conditioning systems as typified by the illustrations below. Dampers, inlet/outlet air diffusers/grilles, cooking appliances, air conditioning coils and ducting shown are typically furnished by others but in part may be available from PennBarry. EXHAUST AIR SUPPLY AIR (VENTILATION) CEILING PLENUM AIR / RECIRCULATION SUPPLY AIR (COOLING / HEATING) RETURN AIR / RECIRCULATION SUPPLY AIR (VENTILATION) BELT DRIVE PERFORMANCE DATA Belt Drive Losses The AMCA Review Committee has developed the chart shown below for the purpose of estimating belt drive losses. To calculate total BHP (including drive losses): Find the BHP of your operating point on the x-axis on the graph below. Follow the vertical line to the curves indicating the range of drive losses. Look at the y-axis on the left and find the drive loss percentage. Calculate the total BHP by adding the drive loss to the operating point BHP. For BHP s below 0.3, use 30%. For totally enclosed, explosion proof, multi-speed and all 1.0 Service Factor motors, fan BHP plus drive losses should not exceed motor rated HP.

Higher fan speeds tend to have higher drive losses than lower fan speeds at the same horsepower. Moving Your Way 5
