There are a number of large-diameter high-volume low-speed (HVLS) fans on the market that are designed for shifting large volumes of air in industrial premises such as workshops, warehouses and factories. But now there’s a new name in the market, which is claiming a new class of equipment, the SHVLS fan, or super-high-volume low-speed fan.
Mammoth Fans has based its design around a permanent magnet synchronous brushless direct-drive motor, which is not only highly efficient, it offers a wider range of control parameters than traditional designs.
Thanks to this direct drive, unlike other designs Mammoth industrial fans have no mechanical gearbox (and no gearbox oil to replace), making them very low maintenance. It also gives them a typical motor efficiency of 86%, compared with 78% for traditional brush and AC motors.
Also, while traditional 7.3-metre industrial HVLS fans will have a speed range from 20 to 50 RPM, the Japanese designed variable speed drive used in the Mammoth fans enables speed control from 5 to 57 RPM, allowing greater control over the airflow and hence the comfort level.
The controller is a wall-mounted unit that provides manual control of the fan speed and displays power consumption in real time.
The Mammoth Fans range comprises two models for commercial premises, sized at 3 and 4.2m, and two industrial models, at 5.5 and 7.3m diameters. All models run from single-phase 240V supplies.
In terms of performance, both industrial fans are rated at 1.8kW with a low 43dB noise level. Maximum airflows are 13,350m3/min for the 5.5m fan, and 14,800m3/min for the 7.3m model.
Mammoth Fans are available exclusively in Australia through Beacon Lighting.
