Standard Construction Features

1Wheel SFD and SFB fans have forward-curved centrifugal wheels constructed of die formed steel with blades securely riveted to a steel backplate and rim. Each wheel is statically and dynamically balanced to precise tolerances.

SWB Series 100 and 200 through size 210 have backward-inclined non- overloading centrifugal wheels constructed of aluminum. Series 200, sizes 212 and larger and Series 300 wheels are constructed of steel or aluminum. Backward-inclined wheels are made of a heavy-gauge material with single- thickness blades securely riveted or welded to a heavy-gauge backplate and wheel cone. SWB Series 300 fans are available with aluminum airfoil wheels. Each wheel is statically and dynamically balanced to precise tolerances.

2Finish All structural steel parts are phosphate treated and coated with Greenheck’s Permatector™ for a long lasting finish. Galvanized construction remains unpainted.

•See housing and drive frame information for specific material and coating.

3Housing SFD and SWB Series 100 housings are constructed of galvanized steel. SFB and SWB Series 200 and 300 housings are constructed of steel and coated with Permatector™. Both are available in clockwise or counterclockwise rotation and are field rotatable to the eight standard discharge positions. Housing sides are bonded to the fan scroll with an airtight lock seam. Fully welded scrolls are available on SFB and SWB Series 200 and 300 models.

4Housing Housing supports are constructed of heavy gauge-steel with formed

installation.

6Drive Series 100 and 200 drive frames are constructed of rugged, welded

Frame	and coated steel members (Series 300 drive frames are constructed of
	reinforced heavy gauge galvanized steel) supporting the shaft and bearings
	to provide rigid reinforcement for the housing. SFD drive frames are
	constructed of galvanized steel, bolted and available in arrangement 4.
	SFB and SWB are arrangement 10.

7Fasteners Corrosion-resistant fasteners are used to secure unit base and blower scroll assembly.

8Motor Heavy-duty ball bearing motors are carefully matched to the fan load. Open drip proof, totally enclosed and explosion resistant enclosures are available.

9Inlet Cone Streamlined inlet cone design provides for low turbulence air intake, reducing intake losses and sound levels.

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.
