Spun Aluminum Centrifugal Fans
LPD
LPD direct drive fans are designed to exhaust air in low CFM (up to 420), with high static pressure capability up 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.
SDBD and SDBDe
SDBD and SDBDe direct drive fans are designed to exhaust air up to 4,984 CFM, with high static pressure capability up to 1-1/2". The non-overloading backward inclined wheel with its higher static pressure capability makes these units suitable for either ducted or non-ducted applications. The spun aluminum exterior provides an attractive appearance. Direct drive units use smaller diameter wheels, 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. Its roof mounting permits short duct runs and more efficient operation.
SDB
The SDB belt drive fans are designed to exhaust air up to 31,563 CFM in high static pressure applications up to 1-3/4". The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Model SDB well suited to applications where quiet operation is important. Belt drive also permits easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation.
STXD, STXDe, and STXDeRHUL
Model STXD direct drive fans are designed to exhaust air up to 4,780 CFM in high static pressure applications to 1-1/2". The 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 or wall mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation. 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.
STXB, STXBRHUL, and STXBHP
STXB and STXBRHUL Upblast Belt Drive Centrifugal Roof/Sidewall Exhaust Fans are designed to exhaust air up to 37,920 CFM in high static pressure applications to 3". The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Series STXB well suited to applications where quiet operation is important. Belt drive also permits easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof or sidewall mounting options permit location near the area to be ventilated, allowing short duct runs and more efficient operation.
STXB-HT2 and STXB-HT
The STXB is now available with the UL Smoke Control Options (HT2 and HT). These fans can provide emergency heat and smoke ventilation in the event of a fire, which can provide valuable time to people exiting or emergency personnel. The HT2 has a steel wheel and is certified to exhaust heat and smoke in emergencies [500°F (260°C) for 4 hours and 1,000°F (538°C) for 15 minutes]. The HT has an aluminum wheel and is certified to exhaust heat and smoke in emergencies [500°F (260°C) for 4 hours].
DB
Downblast belt drive fans are designed to exhaust air up to 28,000 CFM, with high static pressure capability up to 1-1/4". The belt drive results in lower operating RPM and sound levels, making the DB well suited to applications where quiet operation is important. Belt drives also permit easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof mounting permits short duct runs and more efficient operation.
TXB, TXB-HP, TXB-W, and TXB-RHUL
TXB belt drive fans are designed to exhaust air up to 35,000 CFM, with high static pressure capability up to 3-1/4". The belt drive results in lower operating RPM and sound levels, making the TXB well suited to applications where quiet operation is important. Belt drives also permit easy performance adjustments when needed to balance the total ventilation system. The non-overloading backward inclined wheel with its higher static pressure capability makes this unit suitable for either ducted or non-ducted applications. Its roof or sidewall mounting options permits short duct runs and more efficient operation.
