2.	PRODUCTS

2.1	MANUFACTURER
A.	Greenheck India Private Limited, Plot no. 241, Sector-3, HSIIDC Growth Centre, Bawal, 123501, Distt. Rewari, Haryana, India.  Phone 011-91-124-4272494. Fax 011-91-124-4711263. Web Site www.greenheck.co.in.

2.2	GENERAL

A.	Base fan performance at standard conditions (density 1.2kg/m3).
B.	Fans selected shall be capable of accommodating static pressure and flow variations of +/-15% of scheduled values.
C.	Each fan shall be direct driven in AMCA arrangement 4 with propeller secured to the motor shaft.

2.3	FAN HOUSING AND OUTLET

A.	Base fan performance at standard conditions (density 1.2kg/m3).
B.	Housing to be made from either Z275 galvanized steel or mild steel that is hot dipped galvanized to DIN EN ISO 1461. Housing to be seam welded with Integral Rolled Flange for increased housing rigidity and roundness.
C.	Motor support framework to be constructed of structural steel that is suitable to handle the weights of the motor and propeller. Structurally Integral Performance Vanes are critical to the operation and structural support of the fan.

2.4	FAN IMPELLER

A.	A taper lock bushing shall be used to mount the propeller to the motor shaft on the cast propellers and a key and bolt shall be used in conjunction with a machined hub for the welded propellers.
B.	Fan propeller shall use cast aluminum airfoil blades or welded aluminum extruded blades. Cast blades to be adjustable within a cast aluminum hub to allow for performance changes. The propeller shall be both statically and dynamically balanced.
C.	The wheel and fan inlet shall be carefully matched and shall have precise running tolerances for maximum performance and operating efficiency.

2.5	FAN MOTORS AND DRIVE

A.	Motors shall be 3600 RPM, 1800 RPM, 1200 RPM or 900 RPM in 60 Hz (2900, 1500, 975, or 750 in 50 Hz), an enclosure rating of IP55, and a cooling method of IC418 with a 1.0 service factor.
B.	Motors must be standard IEC foot mount or pad mount designs that are readily available from motor vendors.
C.	Motors for emergency smoke ventilation shall use class H insulation for F400.

2.6	SOUND ATTENUATOR
A.	All silencers use Z275 galvanized material for exceptional resistance to corrosion. 
B.	Available in either Inlet Bell or ducted connection up to diameter 1120 mm and only ducted above 1120 mm diameter.
C.	Standard cylindrical perforated casing is made from a continuous sheet of 1.5 mm (315 mm to 1120 mm diameter) and 2.0 mm (1250 mm and above) thick Z275 galvanized with integral flanges on both inlet and outlet side.
D.	All silencers are provided with convenient backing nuts for ease of installation to mount the silencers (i.e. no drilling at site)
E.	Acoustic infill (Rockwool), density 80kg/m3 can withstand up to 400OC backed with black glass tissue (BGT) is rolled over the perforated tube. Black glass tissue avoids fiber erosion in air stream up to velocity 30m/s.
F.	Acoustic infill (Rockwool) thickness used is 50mm for size 315 mm to 800 mm diameter and 75 mm from 900 mm to 1600 mm diameter.
G.	External wrap is 1.0mm thick Z275 galvanized mounted behind rolled in return flanges. This construction provides better look and rigidity in the product.
H.	Guard is optional for all sizes.

3.	EXECUTION

3.1	EXAMINATION

A.	Examine areas to receive fans. Notify the Engineer of conditions that would adversely affect installation or subsequent utilization and maintenance of fans. Do not proceed with installation until unsatisfactory conditions are corrected.

3.2	INSTALLATION

A.	Install fans systems as indicated on the contract drawings.
B.	Install fans in accordance with manufacturer instructions.
