(High Volume Low Speed Fan, HVLS Fan)

Economic, Lightweight, Powerful.

Waterline TORQ Big Fans offer supreme airflow and comfort from a minimally sleek design. This engineering marvel of a fan is equipped with advanced Brushless Direct Current Motor technology that provides the high torque needed to produce an air coverage of up to a massive 1,800m² despite being the lightest fan on the market.

The Most Practical Way of Producing Large Airflow

The High Volume Low Speed Fan (HVLS), also known as Big Fan, is capable of sending large volumes of air downwards with its uniquely edged blade profile, all while operating at a speed no more than 65 RPM. When the slow-moving air column hits the floor, it changes course and creates a ‘floor jet’ that moves outward in a 360° direction. It continues to move along on ground level until it meets the walls, changing direction once again and then moving vertically upwards. 

This tremendous movement of air covers the workspace and ensures that all personnel and equipment are constantly cooled down.

A Breakthrough in Big Fan Design


Equipped with an incredibly light motor, our standard three-bladed TORQGo model weighs a mere 79 kilograms - keeping the load placed on any ceiling structure to a minimum.

How Low Can You Go?

Compatible with down-rods up to 7 meters long, the TORQ series brings the airflow closer to the ground than any other Big Fan

Keeping Things Safe.

Uniquely designed vibration isolation system eliminates the transmission of excessive vibration onto the building stucture, keeping everything securely in place.

No Compromise In Material.

We proudly make our Big Fans from high-grade extruded aluminum alloys of no less than 6061-T6 quality - making this the most durable option in the market.

The Most Energy Saving Fan In The World

Developed in the USA, the TORQ series combines powerful yet impressively lightweight brushless direct-drive motors that generate high levels of torque while only consuming minimal levels of energy. Couple this with its smartly designed lightweight fan structure, our flagship three-bladed model produces a massive 280,000 CMH while only consuming 500 watts – making this the highest CMH per watt Big Fan available anywhere.

Now that’s special.

Is this Energy Saving?

No Maintenance Required. Ever.

Unlike traditional Big Fans equipped with geared AC motors, the gearless direct driven TORQ series represents a generational leap in its product category. No gears mean no oil, and no oil means you don’t need to carry out costly periodic maintenance to check for leakages or perform oil replenishment – saving you the extra time, energy, and additional expenses of doing so.

Additional Features

TORQ Big Fan series offers the option of attaching an industrial High Bay LED light under its frame to illuminate the surrounding space.

Anti-Drop Plate

In the unlikely event that the fan blade is dislodged, it will be secured to the fan assembly by the Anti-Drop Steel Cable and Anti-Drop Plate.

Adaptive Baseplate Mount

Fan unit can be securely mounted on any industrial building truss/ceiling including circular, rectangular, I-Beam, and concrete type.
