Our Partnership

(HVLS) industrial ceiling fans and ventilation systems designed for large-format industrial spaces

The HVLS fan category was pioneered by premium brands that proved the technology in large-format US warehousing operations. FJ Diamond applies the same engineering principles — large-diameter slow-speed blades, direct-drive or gearbox motor options, and variable-speed control — at a pricing point that makes the technology accessible to a wider range of Australian industrial operators. The product range spans ceiling-mounted HVLS fans from 3 metres to 7 metres in diameter, wall-mounted directional fans, and integrated ventilation systems.

Hold Fast Industries positions FJ Diamond fans as the performance-equivalent alternative to the premium HVLS brands for applications in cold storage, food processing, logistics and manufacturing facilities. Our technical team specifies the correct fan diameter, rotation speed and positioning for your facility's dimensions and airflow requirements — and backs every installation with HFI's national service and maintenance support.

HVLS Technology Delivers Measurable Outcomes

HVLS fans are proven to reduce the perceived temperature in industrial spaces by 3–8°C in summer through increased air movement, while in winter they destratify heated air — pushing warm air that collects at ceiling height back down to the working level. This alone can reduce heating costs by 10–30% in insulated industrial buildings. The energy consumption of a single large-diameter HVLS fan is comparable to a standard light fitting — making the return on investment period short and the long-term operational savings substantial.

Right-Sized for Australian Industrial Operations

Australian warehousing, manufacturing and cold chain facilities operate in a climate that creates real thermal management challenges — extreme summer heat, high humidity in coastal locations, and significant heating demands in southern states. FJ Diamond's range is specified and installed by HFI with local climate conditions, facility dimensions and operational patterns in mind. Every installation is supported by HFI's Progressive Maintenance Agreement programme, ensuring your fans continue to operate at peak efficiency for the life of the asset.
