Model SFD Direct Drive

Utility Fans

Supply, exhaust or return air fans shall be of the direct drive utility fan type, in AMCA Arrangement

4 with a single-width, single-inlet housing, in clockwise or counterclockwise rotation as specified.

The housing shall be constructed of heavy-gauge galvanized steel with lock formed seams permitting no air leakage. The housing shall be easily rotated in the field to any of the eight standard discharge positions. Housing supports shall be constructed of heavy-gauge galvanized steel to minimize vibration and rigidly support the motor and wheel.

The fan wheel shall be of the forward-curved type and shall be constructed of heavy-gauge aluminum. Wheels shall be statically and dynamically balanced. The wheel cone and fan inlet cone shall be carefully matched for maximum performance and operating efficiency. Motors shall be heavy- duty ball bearing type matched to the fan load and furnished at the specified voltage, phase and enclosure.

All fans shall bear the AMCA Air Performance seal.

Utility fans shall be model SFD (with forward- curved wheels) as manufactured by Greenheck Fan Corporation of Schofield, Wisconsin, USA.

Model SFB Belt Drive Utility Fans

Supply, exhaust and return air fans shall be of the belt driven utility fan type in AMCA Arrangement 10 with a single-width, single-inlet housing, in clockwise or counterclockwise rotation as specified.

The housing shall be constructed of heavy-gauge steel with airtight lock formed seams. The housing shall be easily rotated in the field to any of the eight standard discharge positions. Housing and bearing supports shall be constructed of welded steel members to prevent vibration and to rigidly support the shaft and bearings.

Model SFB fan wheels shall be of the forward- curved type, constructed of heavy-gauge steel with uniform stamped steel blades.

Wheels shall be statically and dynamically balanced. The wheel cone and fan inlet cone shall be carefully matched for maximum performance and operating efficiency.

Motors shall be heavy-duty, ball bearing type, matched to the fan load and furnished at the specified voltage, phase and enclosure. The fan shaft shall be ground and polished solid steel mounted in heavy-duty, sealed, pillow block ball bearings. Bearings shall be selected for a minimum L10 life in excess of 100,000 hours (L50 average of 500,000 hours) at maximum cataloged operating speed. Drives shall be sized for a minimum of

150% of driven horsepower. Pulleys shall be of the fully machined cast iron type, keyed and securely attached to the fan and motor shafts. The motor pulley shall be adjustable for final system balancing.

All fans shall bear the AMCA Air Performance seal.

Utility fans shall be model SFB (with forward-curved wheels) as manufactured by Greenheck Fan Corporation of Schofield, Wisconsin, USA.

SWB, SFD, SFB specifications

Greenheck Fan’s SFB, SFD, and SWB series represent advanced solutions in ventilation technology, designed to cater to a variety of commercial and industrial applications. Each series brings unique features and optimizations that enhance airflow efficiency and reliability, making them suitable for schools, warehouses, and manufacturing facilities.

The SFB series stands out with its durable construction and high-performance capabilities. These fans are engineered for direct drive applications, offering quieter operation and lower maintenance compared to belt-driven alternatives. The SFB series features efficient backward-inclined airfoil blades, which minimize energy consumption while maximizing airflow. Additionally, they are designed with an innovative airflow path that reduces turbulence and improves overall performance.

In contrast, the SFD series is intended for applications requiring high static pressure capabilities. It incorporates a special housing design that allows for increased efficiency in high-pressure environments. The advanced motor technology in the SFD series contributes to significant energy savings, while the unit's adjustable pitch blades ensure optimal performance across various operating conditions. These fans are particularly popular in commercial kitchen exhaust systems, where effective removal of smoke and odors is critical.

The SWB series, meanwhile, is specifically designed for sidewall applications, making it a versatile option for residential and light commercial use. The SWB fans feature a compact design that facilitates easy installation in tight spaces, and their weather-resistant construction ensures reliable performance even in challenging outdoor conditions. Additionally, these fans utilize energy-efficient motor designs that further contribute to their low operational costs.

All three series prioritize user-friendly operation and maintenance. They are equipped with standard access panels that provide easy interior access for cleaning and servicing, thereby extending the lifespan of the equipment. Greenheck also emphasizes noise reduction in its designs, employing sound-dampening technologies and vibration isolation features to ensure a quieter operation.

In conclusion, Greenheck Fan’s SFB, SFD, and SWB series represent a commitment to innovation in ventilation technology. Their distinctive characteristics, including energy efficiency, durability, and ease of maintenance, make them ideal choices in a wide array of applications, from industrial to residential settings. With ongoing advancements in technology, Greenheck continues to set benchmarks in the industry, ensuring effective air movement solutions that align with modern sustainability demands.
