NIS-CO FANS AND BLOWERS

Inline Fans manufactured by experts!

Inline Centrifugal Fans are quiet and dependable centrifugal fans recommended for a wide range of general exhaust applications where low, medium and high ranges of air volume and pressure are specified, in both ducted and non-ducted ventilation systems. The advantages of belt drive inline centrifugal fans over direct drive fans include quiter operation, adjustable performance to suit operating needs and availability of larger volume units.

All inline centrifugal models feature a durable and rigid housing, inlet cone with overlapping deep-spun venturi profile, non-overloading backward inclined, or airfoil wheel, a heavy duty shaft, pillow block bearings, and shaft and bearing tunel for tube models. Both, sqare and tubular designs utilize standard variable pitch V-belt drive and adjustable motor support base for belt driven models.

Inline Duct Fans are avaialble in tubeaxial and vaneaxial design. These are high performance, axial flow fans designed for duct connected applications, such as meke-up air systems, booster fans, return air fans, or to exhaust contaminated or high temperature air. Heat and smoke emergency exhaust fans include cooling wheel and sealed shaft and bearing tunel in order to withstand higher temperatures during emergency mode.

All tubeaxial and vaneaxial fans are made of heavy gauge steel for maximum strenght and durability. Painted parts are coated with epoxy to provide a protective coating rated excellent for hardness, impact resistance, adhesion and chemical resistance. All blade assemblies are dynamically balanced. Drive mechanism includes V-belts and fixed pitch, or adjustable pitch pulleys. Totally enclosed motors are standard for all applications.

Accessories: Atomatic and Motor-Operated inlet vane dampers, companion flanges, mount feet, spring vibration isolators, rubber-in-share vibration isolators, suspended mount, vertical mounting brackets, spark resistant construction, explosion proof construction, high temperature construction and many others are standard avaialble options.

All models bear the AMCA Seal.
