The catalog provides a detailed procedure for selecting the appropriate fan, considering factors such as air flow, system resistance, and density corrections. It emphasizes the importance of accounting for accessory losses and unusual inlet/outlet conditions.
1. Calculate the equivalent selection fan static pressure by adding system fan static pressure losses to the standard density.
2. Re-enter selection tables with the equivalent static pressure and required ACFM.

IRT — (Industrial Radial Tip) The radial tipped wheel design is the most efficient selection in the industrial exhauster series of fans. It offers efficiency while maintaining some slight material handling capabilities where there is a light dust loading or slightly abrasive type material in the airstream. The performance is very stable throughout most of the operating range. Excellent selection where energy savings are a premium but material handling characteristics are required. Radially Tipped (RT) Series: The major usage for this product is in process fan applications. The advantage of the...

There are many applications which have a large fan moving a high volume of air but at a low static pressure, so a large horsepower motor is not required. In these instances, many times the motor is not large enough to turn the fan wheel and shaft due to high inertia requirements. In these instances one needs to consult with the motor or starter manufacturer to see if the motor is capable of the necessary load inertia. The chart that follows gives quick calculations that can be performed to see if the motor has the necessary start up capabilities. MOTOR TORQUE WR² x N² t= 1.62 x HPm t = Start...

FAN EFFICIENCY Mechanical Efficiency is defined as: The ratio of fan output to the power applied to the fan, can be helpful in selecting fan size, type or manufacturer for the same application. ME = TP x CFM 6356 x BHP TP = Fan Total Pressure =SPout + VPout SPin – VPin – NOTE: Spin normally carries negative (-) sign Static Efficiency is defined as: The ratio of fan output less the kinetic energy (outlet volocity pressure) leaving the fan to the power applied to the fan. SE = SP x CFM 6356 x BHP SP = Fan Static Pressure =SPout + VPout SPin – VPin – VPout – Therefore, ME is always greater than...

^Kil"Technology Corp. CORRECTION FACTORS Variable Inlet Vanes 30% of wide open (free air) flow are possible with inlet vanes. As an inlet vane closes it imparts a spin on the direction of the wheel rotation. This pre-spin of the air helps to maintain down conditions. To compensate for this slight loss, you must increase correction is shown as pressure loss Outlet Damper Due to resistance in air flow caused by a wide open position on the outlet damper, a correction must be made to obtain required performance. Outlet damper losses must be added to the fan static pressure before entering the performance...
