Frequently asked questions about
TORQ HVLS fans

The High-Volume Low Speed Fan (HVLS), also known as Big Fan, is a fan 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.

No, as the Big Fan has a relatively slow-moving RPM, it is virtually silent during operation.

In practice, the most typical implementation of ventilation fans that you find in factories are the use of smaller wall hanging or portable type fans designated for a single person or at most a single small area/zone. This approach requires a large number of small fans to be installed to get any adequate amount of airflow required for a typical factory, which in turn would needlessly drive up the electricity bill.

Enter Big Fans. With one single big fan unit, you can produce an enormous amount of air coverage that’s equivalent to 60 smaller wall hanging fans or more. That’s the beauty of it – save space, save electricity, and yield incredible air flow.

A typical installation of one (1) Big Fan unit can take up to 2 days on average. However, more complicated installations that involve extremely high ceilings, physical obstructions and uncommon mounting types may take longer.

We highly recommend that you allow one of our highly experienced installers to perform the installation for you to guarantee the safe operation of the fan.

All our fans are proudly designed in the USA and manufactured in Thailand. 

We provide 2-years warranty on the electronics and motor and 5-years warranty on the mechanical fan structure.

No maintenance is required for the motor as our fan is driven by a gearless Direct Current (DC) motor. The absence of gears mean that no periodic oil change is required unlike traditional AC type motors.

However, we still recommend to perform a yearly inspection on the mounting system of the Big Fan, ensuring that all hanging wires and mounting accessories remained tightened.

If you would like us to carry out your yearly inspection, please contact our Waterline service team to arrange a time for us to visit you to do so.
