Three Simple Steps

Steps and Basic Requirements:

• Phase - single or three
• Static Pressure in In WG (inches of water)
• Flow in CFM (Cubic Feet Per Minute)

*Explosion resistance or XPFC -CIP (Explosion Resistance - Carbon Impregnated)

1. Static Pressure: Locate the required or estimated static pressure in InWG (Inches of Water) on the selected series performance chart. If none has been specified it always a good rule to use a minimum of 0.25

2. Flow: Find the desired flow rate in CFM (Cubic Feet per Minute) on the selected series performance chart.  Note: For balancing, use a damper for single-phase, and a damper or VFD for three-phase

3. Locate the Fan Model: The model is listed in bold above the performance curve line where the static pressure and flow rate intersect.  

Example:

A Static Pressure of 1.5 InWG and a Flow of 300 CFM is MODEL = P15-2
