7. How to Ventilate Buildings
November 08, 2013

Power roof fans of the type manufactured by CB Fan Co. are very similar in basic design to the wall fans. Size and capacity closely parallel the wall fans.

9. Fan Performance Table
November 08, 2013

Fan performance tables are based on laboratory test data and are sometimes referred to as "test curves". A typical test curve will often define the performance parameters for a specific design and size of fan, operating at a given speed, moving a gas of a given density. Inspection of this graph will show that it is actually composed of four separate curves: • Static Pressure vs. Volume Curve: This plot is the one often referred to as the "fan curve" or "characteristic curve" because it defines all the possible pressure-volume combinations the fan is capable of producing given stated condi...

10. Different Methods of Buildings Ventilation
November 08, 2013

A vital element in the successful breeze conditioning system is a supply of clean, cooler, fresh air. While such an ideal air supply may not be available, common sense dictates that air being supplied into the building should be from the best available source. Avoid recirculating air that has just been exhausted from the building or another nearby structure. It is usually wise to locate the exhaust fans near the area where heat-producing machinery is found in the industrial building. This has the very practical advantage of exhausting this superheated air near its source and preventing a ... (read more)

November 08, 2013

Below is a time-honored approach to a determination of air volume requirements. It is based on the theory that a complete change of air in a room or building should be made at a certain time frequency. The rate selected is frequently an arbitrary decision. It may be based on experience with similar installations or may be established by a health or safety code. Many fan manufacturers have published charts that show recommended rates of air change for typical installations. Although the rate of air change method of calculating air volume has been used for many years, Buffalo Fan engineers have ... (read more)

16. How to Improve Fans Performance
November 08, 2013

Even in large fans, a sixteenth of an inch of material build up can reduce performance. Centrifugal fans will move some air even when running backwards. While some types would use so much horsepower they would trip circuit breakers, other design s could run for years without being detected. Fan components may be out of position due to routine cleaning or painting or the wheel could have shifted during shipment. For backward inclined fans, the relation of wheel to inlet cone is very critical. Even a quarter of an inch can have a major impact. The fan’s installation and maintenance literature sh...

21. Fan Noise Problems
November 07, 2013

Some of the more common sources of abnormal or unanticipated noise are: 1) Fan wheel unbalance. 2) Resonance of fan or attached components. 3) Rotating components rubbing on stationary parts. 4) Failing, misaligned, or contaminated bearings (on the fan or on the motor). 5) Air leakage. This can allow sound leakage and also generate a whistle-type noise. 6) Belts slipping. 7) Coupling misalignment. 8) Motor noise, especially with improper power supply. Inverter drives may increase motor noise at certain speeds. 9) Air turbulence. 10) Operation in surge. 11) Loose components. 12)... (read more)

November 07, 2013

As a rule, the factory's ventilation equipment is inadequate for anything more than safeguarding the health of the occupants. In some cases, it does an inadequate job of this. To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and/or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure. The most effective way to incorporate wall or roof exhausters into a system will be discussed below. A large number of buildings use exhaust fans and/or power roof ventilators t... (read more)
