Models SFD and SFB

Greenheck models SFD and SFB forward-curved utility fans have been designed for supply, exhaust and return

air applications requiring low to medium air volumes and pressures. You will receive the following benefits with these fans:

SFD fans are available in four sizes (6, 7.5, 9 and 10) with different rpm motors. Capacities range from 300 to 2,600 cfm (510 to 4,600 m3/hr) with static pressures to 2.5 in. wg (623 Pa).

SFB fans are available in ten sizes (9 through 30) with capacities ranging from 360 to 25,200 cfm (610 to 42,800 m3/hr) and static pressures to

3.5 in. wg (872 Pa).

Greenheck utility fans are designed, engineered and tested prior to shipment to provide years of smooth, vibration-free operation with minimal maintenance.

The fan may be mounted indoors or outdoors.

All fan sizes are tested in our AMCA accredited laboratory to ensure complete and accurate performance ratings. All models are licensed to bear the AMCA Air Performance seal. Performance as cataloged is assured.

Model SWB

Greenheck’s backward- inclined utility fans have many advantages; higher operating efficiencies, non-overloading horsepower curves and higher pressure capabilities. You will also receive

the following benefits with these fans:

SWB Series 100 in ten sizes (106 through 124) with capacities from 70 to 11,000 cfm

(120 to 18,700 m3/hr) and static pressures to

3.0in. wg (747 Pa).

SWB Series 200 in twelve sizes (206 through 224) with capacities from 70 to 13,700 cfm

(120 to 23,300 m3/hr) and static pressures to

5.0in. wg (1250 Pa).

SWB Series 300 in seven sizes (327 through 349) with capacities from 4,600 to 54,000 cfm

(7,700 to 91,700 m3/hr) and static pressures to

5.0in. wg (1250 Pa).

Three different series of construction will meet your exact needs in the most efficient manner.

Greenheck utility fans are designed, engineered and tested prior to shipment to provide years of smooth, vibration-free operation with minimal maintenance.

Fans are tested in our AMCA accredited laboratory to ensure complete and accurate performance ratings. All models are licensed to bear the AMCA Air Performance seal. SWB 300 Series AF fans are licensed to bear the AMCA Sound and Air Performance seal. Performance as cataloged is assured.

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.
