2.2	DIRECT DRIVE DIRECTIONAL DESTRATIFICATION FAN - GREENHECK 
MODEL DDF 

A.	General Description:
1.	Fans are designed to destratify spaces with ceilings up to 65 feet to maintain even temperatures from floor to ceiling.
2.	Fans are available in three sizes with nominal propeller diameters ranging from 10 inches to 14 inches (10 - 14 unit sizes).
3.	Performance capabilities range between 640 to 1,500 cubic feet per minute(cfm)
4.	Maximum continuous operating temperature of 104° Fahrenheit
5.	Each fan shall bear a permanently affixed manufacturer's mylar nameplate
containing the model number and individual serial number of the fan.
B.	Propeller:
1.	Propeller shall be constructed of aluminum blades riveted to a steel hub.
2.	A standard square key and set screw or tapered bushing shall lock the propeller to the motor shaft 
3.	The propeller and fan inlet shall be matched and have precise running tolerances for maximum performance and operating efficiency.
C.	Propeller Guard:
1.	Propeller guard prevents objects or obstructions from contacting the fan propeller.
2.	Propeller guard must comply with OSHA guidelines for safety
3.	Propeller guard shall be constructed of structural steel members to prevent vibration and to support the weight and load of the motor and propeller.
D.	Electronically Commutated (EC) Motor: 
1.	Motor Enclosure: Totally Enclosed Non-Vented (TENV) - No opening in the frame or brackets. Air over cooling.
2.	Motor to be a DC electronic commutation (EC) type motor specifically designed for fan applications. AC induction type motors are not acceptable. Examples of unacceptable motors are: Shaded Pole, Permanent Split Capacitor (PSC), Split Phase, Capacitor Start and 3 phase induction type motors.
