High Performance Axial Fans Model AX • High Efficiencies • Low Sound

Greenheck’s high performance axial fan, Model AX, are direct driven axials designed for inline air ventilation in commercial or industrial buildings. The casing design and construction are well suited to indoor or outdoor applications and can be easily installed in ducted or non-ducted systems. The AX is designed to reduce operating costs with improved efficiency. Additionally, the AX blade design offers inherently lower sound levels than other axial fans. Typical Ventilation Applications include: • Supply and return fans for air handling equipment • Continuous duty operation at 110°F • Emergency...

Value Added Features l~^GREENHECK Building Value in Air. Extensive R&D and Performance Testing Program High Performance Propeller The AX blade shape and hub are designed to move high volumes of air with less power to save on longterm energy costs. Blades Tight tolerances between the blades and casing improve overall efficiency. This improved efficiency in turn reduces the overall sound levels, but the AX is even quieter as a result of the wide blade shape and unique blade spacing. The asymmetrical blade locations reduce the blade pass frequency tones while generating a smoother sound spectrum....

Configuration Options [~^GREENHECK Building Value in Air. The AX is available in a variety of casing configurations to provide solutions for many different applications and design requirements. AX Long Casing (Standard) The long cased axial is designed for ducted or plenum type applications. The all welded long-casing completely covers the motor and propeller assembly. This design offers numerous mounting options including horizontal or vertical orientations for either ceiling hung or base mounting. AX Vane Section (Option) The long cased axial with vane section further improves the efficiency...

Other Features & Benefits Electrostatic Powder Paint and Protective Coatings All internal and external steel components are electrostatically powder painted prior to assembly with an industrial polyester urethane, Permatector™. This finish is excellent for both indoor and outdoor applications and has added resistance to many common chemicals. One advantage of powder coatings is that they offer a uniform, durable and high quality finish that uses a one‑coat process applied over a phosphatized surface. Charged paint particles are able to penetrate and fill voids in hard to reach locations like...

Optional Accessories The AX is available with optional accessories to improve the ease of installation and provide safety during operation. Accessories supplied by Greenheck conform to our high standards of quality. Universal Mounting Brackets allow for field rotation of the AX from horizontal ceiling or base mount and vertical ceiling or base mount applications. The brackets also provide an attachment point for any vibration isolation devices. Companion Inlet and Outlet Flanges are available to aid the connection of the fan casing flange to ductwork. Companion flanges are prepunched to match...
