VAD Direct Drive Vaneaxial Type VANAX Fan
American CoolAir Type VanAx vaneaxial VAD fans are true vane axial fans designed for a wide range of commercial and industrial applications. High pressure efficiency permits the fans to be installed anywhere in the system — in any position. The fans can be used for either supply or exhaust by simply turning the entire unit to move air in the desired direction. Vanax fans are extremely compact and well suited to locations where space is limited, and can often be easily mounted directly to the ductwork. As a result of very close tolerances and carefully matched vanes and rotors, Vanax fans offer exceptional performance across its size ranging from 12 to 60. VAB fans are rated from 1,200 to 47,000 CFM and static pressures up to 4”.
VAD Construction: CoolAir Model VAD feature a rolled steel casing with a die formed steel vane section. Both the steel casing and vane sectionare coated with a protective epoxy paint finish. The vane section for both the VA and VAD also serves as the motor mount for the fan, and the cast aluminum rotor is mounted directly to the motor shaft. This direct drive arrangement provides years of maintenance-free service. The cast aluminum rotor is mounted directly to the motor shaft. Motors for the VAD are of Totally Enclosed Air Over (TEAO) design. The Adjustable Pitch Airfoil Blades of the fan prop allow the performance of a VAD unit to be precisely matched to the system in which it operates.
Motors: Totally enclosed motors are standard. Several alternatives are available to fit your specific needs, such as explosion proof. Only nationally recognized brand motors with nationwide service facilities are used. Motor availability is limited on certain fan models. Totally enclosed type, single phase motors have built-in overload protection, other motors may require separate overload protection.
Finish: VAD and VAB parts requiring painting are processed through the advanced American Coolair multi-stage pretreatment system prior to the application of any coatings to ensure maximum finish adhesion. These parts are then powder coated with epoxy to provide a protective coating rated excellent for hardness, impact resistance, adhesion and chemical resistance.
Controls and drives: all standard controls available.
