P15SS2P050 Plastec Ventilation Duct Fans Plastec Series, Single 115/230V

They are designed to exhaust fumes from highly corrosive environments such as laboratories, chemical plants, hospitals, universities, etc. 

How to Choose a Fan Model-Pole

Steps and Basic Requirements:

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

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 is 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
