What are fan sizes available for these large HVLS ceiling fans?

We have three main types of large HVLS ceiling fans which are:

The RTFANS industrial HVLS fans have five models of heavy-duty industrial ceiling fans. The diameter ranges from 3.7m to 7.3 meters. All models have different RPMs, applicable area diameter, current, and weight. You can select large or extra-large industrial ceiling fans for your use. Our team will assist you in getting the right size. Commercial HVLS fans have a diameter from 4m to 2.8m. These are available in four models. PMSM fans have a diameter from 2.8m to 7.3m. There are six models from the applicable area of 400 to 1,800 sq. meters.

Using this information

Use this page to prepare a clearer conversation with your facilities, engineering, or purchasing team. Confirm the building size, ceiling height, occupancy, process conditions, climate, electrical service, water and drainage needs, and any required exhaust or source-capture controls before choosing equipment. Published answers and references describe a starting point; a project-specific review is still needed when safety, code compliance, indoor air quality, or process emissions are involved.

Before requesting a quotation, collect the information that changes equipment selection: a plan or sketch of the space, mounting and clearance constraints, existing HVAC supply and returns, exhaust fans, doors and louvers, operating hours, peak occupancy, noise expectations, cleaning method, and maintenance access. For industrial sites, identify welding, dust, oil mist, solvent, combustion, or vehicle exhaust sources separately from comfort zones. For evaporative systems, confirm climate, humidity tolerance, water quality, drainage, and winterization needs. This preparation helps the RTFANS team explain what the referenced equipment can do, what must be designed separately, and which measurements or approvals are needed before installation.
