Inline Fans

The QEI is a mixed flow fan for commercial, institutional, and industrial applications handling everything from clean air to high temperature exhaust. Model offers multiple construction levels to match the application providing best performance at the most economical solution. Features performance enhancing airflow straightening vanes and easily accessible motor outside of the airstream. The QEI model has a variety of mounting options for indoor and outdoor locations.

Model QEID is a compact, direct drive version of the QEI for space critical applications. It requires less maintenance with fewer components, while airflow straightening vanes assist in improved performance. For best value by application, the QEID has the construction level options, but with performance and lower maintenance benefits by eliminating belts, pulleys and fan shaft bearings. Vari-Green® EC motors or induction motors with factory programmed VFD provide easy adjustment and control.

Model QEID FJ Fume Jet is an ideal fan for exhausting chemical or odor-laden air. Standard with Spark A resistant construction, it provides the highest level of protection. The airstream pathway is constructed of corrosion-resistant, lightweight composite materials and includes a durable flanged casing for duct connections. This direct drive model has an encased Vari-Green® EC motor with uniquely designed hollow support channels isolating the motor from the contaminated airstream and dissipating motor heat to the fan's exterior.

Model SQ is a direct drive square inline mixed flow fan designed for intake, exhaust, return or make-up air applications when efficiency, sound and cost are a major focus. Units have multiple mounting options for indoor and outdoor locations, Vari-Green® EC motors and a variety of accessories that make this model a great solution for many applications. All of these features add up to make the SQ Mixed Flow fan the most cost effective mixed flow option on the market.

Model BCF is a belt-drive inline cabinet fan designed for efficiency in supply, exhaust and ducted return applications. Units feature flexible mounting configurations, forward-curved wheels and galvanized steel housings.

Model BSQ is a belt drive square centrifugal inline fan designed for intake, exhaust, return or make-up air applications where space is a major issue. Units feature a galvanized steel housing and aluminum backward-inclined wheel.

Model SQ is a direct drive square centrifugal inline fan designed for intake, exhaust, return or make-up air applications where space is a major issue. Units feature a galvanized steel housing and backward-inclined wheel.

Model AX is a direct drive fan offering increased performance capabilities and several installation configurations to suit project needs. The unit has one casing option: a long casing that completely covers the propeller and motor, and bolt-on vane section with 15% performance improvement. The vane section provides total efficiencies in excess of 70%, which improves efficiency and reduces operating costs.

The TBI-CA is a belt-driven model with a cast aluminum hub and airfoil propellers. Key features are compact size, mounting flexibility, and ease of performance adjustments. Model TBI-CA cast aluminum impeller, sealed internal belt and bearing enclosure meets spark resistant specifications. Typical applications include warehouse, industrial ventilation and paint booth fume exhaust

Model TBI-FS has a fabricated steel hub and airfoil blades. The unit is suitable for continuous high temperature (400ºF/204ºC max.). Bolt-on straightening vanes are available for increased efficiency. Typical applications include clean air, industrial processes, and high-temperature exhaust.

VAB belt drive models offer flexibility to adjust pulleys and easy access to the motor with low vibration level for smooth operation. System balancing is made through sheave changes or manually adjustable blade pitch.

VAD direct drive model has the most compact design for the available performance range with minimal maintenance and low vibration levels. Final system balancing uses manually adjustable blade pitch.
