URANUS HEAVY DUTY EXHAUST FAN 24"/600MM

IGMA range of Heavy Duty Exhaust Fans are developed to combine high quality with being economically priced, economical to maintain and economical to operate.

Applications

IGMA Heavy Duty Exhaust Fans can be used in a wide variety of ventilation applications like power plants, warehouses, factories, parking garages, poultry farms or any general ventilation need.

Construction

IGMA Heavy Duty Exhaust Fans are of the propeller fan construction. The blade tip clearance is kept small and uniform to prevent air from flowing back around the propeller and thus achieving higher static pressure. The fans are designed to move large volumes of air at low static pressure but will perform well also at slightly elevated static pressure.

Performance

Fan Performance Airflow rate and static pressure are closely related for fans and ventilation systems. The airflow rate delivered by a fan is measured in cubic feet per minute (cfm) against a static pressure measured in inches of water. The amount of air moved is inversely rated to the static pressure. As the resistance to airflow (static pressure) increases, the delivered airflow capacity decreases. Therefore, a fan delivers more air against a lower static pressure than a higher static pressure. Common measurements used to describe the characteristics of a fan are blade diameter, revolutions per minute (rpm) and motor horsepower. These are useful measurements but without performance characteristics such as airflow and static pressure, they give only general indicators of fan capacity. Test results comparing the performance of 36-inch diameter fans used in the ventilation of enclosed buildings can show big variability in fan performance even though they are similar size fans. At a static pressure of 1/10 inch, the air delivery capacity of fans can easily vary from 6,400 to 10,000 cfm. These large variations in fan capacity for similar diameter fans significantly affects the selection process of fans. This shows the importance of selecting fans based on performance rather than strictly fan diameter or horsepower.
