2.2 HIGH VOLUME, LOW SPEED FANS – MACROAIR AIRVOLUTION-D3
A. Regulatory Requirements: Assembly standards

1. Sustainable Characteristics: The MacroAir AirVolution-D3 is designed to generate large volumes of thorough air movement throughout a space at a low velocity to create a comfortable environment at a low energy consumption, contributing to cost-efficient facility management and operation practices. The efficiencies of the MacroAir high volume, low speed fan concept are such that air is thoroughly mixed within a space, achieving thermal equalization, and gentle air movement is delivered to occupants contributing to indoor air quality. The MacroAir AirVolution-D3 is designed with forward (counter-clockwise) and reverse (clockwise) performance capabilities, for cooling and heating solutions. Sensor less Direct Drive Motor: The MacroAir AirVolution-D3 HVLS fan model utilizes a specialty Direct-Drive (D-Drive) radial-flux sensor less DC motor, utilizing a small ring of ultra-low resistance copper for a motor coil.
