S&P - Fans & Ventilation

When S&P started the project to improve their upblast and downblast spun aluminum power roof ventilators they set fan efficiency as their number one goal. S&P knew the wheel, the heart of the unit, was the place to start so they took meticulous steps to design and engineer the most efficient and cost effective wheel they could. Their new wheel features curved blades, solid rivets and improved cooling vanes which together ensure the best fan performances possible. 

Model RED direct drive fans are designed to exhaust air up to 3,000 CFM in high static pressure applications to 1”. The spun aluminum exterior provides an attractive appearance. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable  for either ducted or nonducted applications. Its roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation.

The RED is generally used to exhaust air from all types of commercial and institutional buildings such as hospitals and health care facilities, schools, recreational buildings, machinery and equipment rooms, offices, retail stores and similar applications.

Model LPD direct drive fans are designed to exhaust air in low CFM, up to 420, high static pressure applications to 1-3/4”. When aesthetics are a concern the low profile design of the LPD is the perfect choice. The LPD is generally used for bathroom, office, or light commercial ventilation in ducted systems; and can be mounted either on the roof or wall as the application requires.

Model CWD direct drive fans are designed to exhaust air up to 3,360 CFM in high static pressure applications to 1”. The spun aluminum exterior provides a pleasing appearance, weatherproof construction and resistance to corrosion. The low silhouette design is less noticeable on the building exterior and the removable dome provides easy access to the fan interior for service and cleaning. The non-overloading backward inclined centrifugal wheel with its high static pressure capability, makes it suitable for either ducted or nonducted applications. It should be used where a sidewall mounted location is preferred to roof mounting. Direct drive units use smaller diameter wheels with lower rpm's, resulting in low sound levels and quiet operation. They have no belts or fan bearings to maintain or adjust and consequently require very little maintenance.CWDs are used to exhaust relatively clean air from a variety of industrial, commercial and institutional buildings such as machinery and equipment rooms, storage areas, office buildings, restaurants, retail stores, schools and similar buildings.

Model KSF fans are roof curb or curb cap mounted filtered supply fans rated from 375 to over 12,000 CFM, with static pressure capabilities to 2”. They are specifically designed for filtered make-up air in kitchen hood applications. Model KSF’s rugged design with heavy-gauge galvanized construction provides maximum weather protection, long life and the utmost in performance efficiency. The forward curved centrifugal blower provides efficient air flow at low sound levels with static pressure capabilities to handle ducted air systems or hoods within a building. The filters are washable and are reusable to reduce maintenance costs. Quick release hood latches make routine cleaning and maintenance fast and easy.
