Options and Accessories

Greenheck Fan SFB, SWB, SFD manual Options and Accessories

UL/cUL 762 - SWB Series 200 and 300 models are listed for grease removal (UL/cUL 762). The UL/cUL 762 option includes a weatherhood, threaded drain connection and access door. Indoor mounting requires the fan to have welded scroll construction.

Weatherhood - Available to completely cover the motor and drive compartments; protecting the shaft, bearings, motor and drive components from moisture and other adverse weather conditions. Weatherhoods are vented to provide sufficient motor cooling, designed to meet OSHA guidelines and are easily removed for service access. Series 300 includes an access door.

Drain Connection - Threaded drain connections can be provided to drain moisture from the bottom of the fan housing.

Grease Trap (SWB Only) - Aluminum trap is designed to collect grease residue and avoid drainage onto roof surface. Disposable grease absorbents are available for easy maintenance.

Access Doors - Access doors provide access for inspection and cleaning. Either bolted or hinged, quick opening access doors are available on all models except SFD. (Series 100—bolted option only)

Welded Scroll Construction - Welded scroll construction is available on SWB Series 200 and 300.

Aluminum Construction - Aluminum airstream option is available on SWB Series 200.

Dampers - Gravity or motorized parallel blade backdraft dampers feature sturdy galvanized frames with prepunched mounting holes, aluminum blades with felt edges and balanced design for minimal resistance to airflow. Backdraft dampers are not suitable for downblast or bottom

angular downblast discharge positions. The fan must be supplied with a flanged outlet to install a backdraft damper directly to the fan. Heavy-duty dampers are available for high pressure applications on fans with motors equal to or greater than 71⁄2 horsepower.

Disconnect Switches - A wide selection of NEMA rated switches are available for positive electrical shutoff and safety, including: dust-tight, rainproof and corrosion-resistant.

Wiring Pigtail - Allows direct hookup to the power supply eliminating field wiring to the fan.

Extended Lube Lines - Lubrication lines with grease fittings are extended from shaft bearings to the base of the drive frame panel or weatherhood for easy bearing lubrication.

Inlet and Outlet Guards - Constructed of expanded metal mounted in a steel frame to provide protection for non-ducted installations. The guards can be easily removed for fan maintenance or inspection.

Flanged Inlet and Outlet - Flanges are available for damper mounting or flanged duct connections. Inlet flanges have prepunched mounting holes. Outlet flanges are bolted on standard; welded for UL 762 applications

Companion Flange - Connects to the inlet flange and then attaches to the ductwork. Recommended for slip-fit duct connections.

Inlet Vane Dampers (SWB only) - External inlet vane dampers are available on model SWB fans, sizes 112– 124 and 212–224. External vanes are mounted on the inlet flange. Inlet vane dampers feature

zinc-plated steel blade axles, stainless steel washers and bearings. Vanes can be used for either manual or automatic operation, with controls furnished

by others. Maximum operating temperature is 200°F (93°C).

Coatings - A wide variety of coatings and

colors are available for decorative to acidic applications on SFB and SWB Series 200 and 300. All Greenheck coatings can be found in the Performance Coatings for Commercial and Industrial Fans publication.

Permatector™ is our standard coating. Typically used for applications that require corrosion resistance in indoor and outdoor environments.

Hi-Pro™ Polyester is resistant to salt water, chemical fumes and moisture in more corrosive atmospheres. Typically used for applications requiring superior chemical resistance, excellent abrasion and outdoor UV protection. This coating exceeds protective qualities of Air Dried Heresite and Air Dry Phenolic.

Baked Enamel Decorative Coatings are heat cured enamels applied as electrostatic powders. Customers can choose from 16 standard decorative colors or color match any color.

Heat Slinger and Shaft Seal (all belt models) - Heat slinger is an aluminum cooling disc mounted on

the fan shaft between the inboard bearing and the fan housing. The disc dissipates heat conducted along the fan shaft.

The shaft seal with an aluminum rub ring is available for applications where

contaminated or high temperature air is being handled.

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.
