FSD Series Square Inline Mixed Flow Centrifugal Fan, 20" Duct (3,400 CFM)

Fantech FSD mixed flow centrifugal type exhaust/supply fans for moderate size ventilation applications were specifically designed to provide the high flow of axial designs plus the higher pressure, non-overloading characteristics of backward curved impellers. Fan motors are capable of operating in air stream temperatures up to 140°F. Motor bearings are a permanently sealed, self lubricating ball type.

The square design provides a larger discharge area than tubular centrifugal or vane axial fans, so outlet velocities are reduced for quieter operation. 100% speed controllable through voltage reduction allowing for on-demand ventilation or precision balancing of systems.

Features:

• Lightweight square design provides larger discharge area and quieter operation
• Straight-through airflow design allows easy installation; no installation extras required. Can be mounted at any angle, anywhere along ductwork.
• Galvanized steel housing
• Permanently lubricated sealed ball bearings
• 100% speed controllable
• External rotor motor
• Automatic reset thermal overload protection

• Terminal box with prewired electrical strip
• Mixed flow impeller design incorporates high flow with higher pressure, non-overloading characteristics and automatic reset thermal overload protection
• Suitable for airstream temperatures of up to 140° F
• UL Listed
• Three-year warranty
