1.5 SUBMITTALS
A.	Provide dimensional drawings and product data on each mixed flow fan.
B. 	Provide fan curves for each fan at the specified operation point, with the flow, static pressure and horsepower clearly plotted.
C.	Provide outlet velocity of mixed flow fans and both inlet and outlet sound power readings for the eight octave bands. 
D.	Strictly adhere to QUALITY ASSURANCE requirements as stated in section 1.4 of this specification.

1.6	DELIVERY, STORAGE, AND HANDLING
A.	Deliver materials to site in manufacturer’s original, unopened containers and packaging, with labels clearly indicating manufacturer, material, products included, and location of installation.
B.	Store materials in a dry area indoor, protected from damage, and in accordance with the manufacturer’s instructions. For long term storage, follow manufacturer’s Installation, Operation and Maintenance manual.
C.	Handle and lift fans in accordance with the manufacturer’s instructions. Protect materials and finishes during handling and installation to prevent damage. Follow all safety warnings posted by the manufacturer.

1.7	WARRANTY
A.	Submit, for Owner's acceptance, manufacturer's standard warranty document executed by authorized company official. Manufacturer's warranty is in addition to, and not a limitation of, other rights Owner may have under Contract Documents.
1.	The warranty of this equipment is to be free from defects in material and workmanship for a period of 12 months from the purchase date. Any units or parts which prove defective during the warranty period will be replaced at the manufacturers’ option when returned to the manufacturer, transportation prepaid.
2.	Motor Warranty is warranted by the motor manufacturer for a period of one year. Should motors furnished prove defective during this period, they should be returned to the nearest authorized motor service station.

2. PRODUCTS
2.1	GENERAL
A.  	Base fan performance at standard conditions (density 0.075 Lb. /ft3).
B.	Fans selected shall be capable of accommodating static pressure and flow variations of +/-15% of scheduled values.
C.	Each fan shall be direct drive in AMCA arrangement 4 according to drawings. 

2.2	FAN HOUSING AND OUTLET
A.	Fan housing to be aerodynamically designed with high-efficiency inlet, engineered to reduce incoming air turbulence.
B.	Tubular fan shall include an outer shell formed and rolled from a single piece of galvanized steel. Joint seem between matching edges are fully welded along the length of the tube for increased strength. Stich welding or joints with fasteners are not acceptable. Seem weld to be sprayed with zinc coating for rust protection.
C.	Inner housing including inlet cone, support structure and air straightening vanes shall be constructed of high strength co-polymer composite material.
C.	All mixed flow housings shall include vanes to straighten airflow prior to exiting the fan discharge. Vanes shall include integrated cooling channels to dissipate heat away from the motor.
D.	Straightening vanes and motor support shall be fused to the inner fan body. Mechanical fasteners or adhesives are not allowed.
E.	Fans meet all requirements of AMCA Spark A construction with no ferrous materials in the airstream.
F.	Motor shall be completely encapsulated and not exposed to air stream.
G.	Fan to  have inlet and outlet punched flanges for mounted directly to duct work.

B.	Motor enclosure shall be Totally Enclosed Non-Vented (TENV) – No opening in the frame or brackets. Airflow over motor is not needed. Electronic commutation type motor (ECM) 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.
C.	Motors are permanently lubricated, heavy duty ball bearing type to match with the fan load and pre-wired to the specific voltage and phase.
D.	Internal motor circuitry to convert AC power supplied to the fan to DC power to operate the motor or integrated variable frequency drive.
E.	Motor shall be speed controllable down to 20% of full speed (80% turndown). Speed shall be controlled by either a potentiometer dial mounted to the exterior of the fan housing or by a 0-10 VDC signal.
F.	Motors can achieve up to 95% efficiency
G.	Motor power and control wiring shall be extended to the exterior of the fan housing. Wiring shall not be exposed to the airstream.
