Frequently Asked Questions (FAQ)
Q1: What does HVLS mean, and how is it different from traditional fans?
A: HVLS stands for High Volume, Low Speed. Unlike small, fast-spinning fans, HVLS fans
rotate slowly but move massive volumes of air to efficiently cool large spaces without turbulence
or noise.
Q2: Can HVLS fans replace air conditioning systems?
A: While not a direct replacement for HVAC, HVLS fans significantly reduce cooling and
heating loads, making them ideal as a cost-effective supplement.
Q3: Are they suitable for both summer and winter use?
A: Yes. In summer, they create an evaporative cooling effect; in winter, they push down
warm air trapped at the ceiling to maintain consistent temperatures.
Q4: How much energy do they consume?
A: Despite their size, HVLS fans are energy-efficient—most models consume less than 1 kW at
full speed and can run on BLDC motors or variable frequency drives.
Q5: What’s the noise level during operation?
A: Thanks to precision engineering and brushless motors, HVLS fans operate at near-silent
levels, making them perfect for places where low noise is essential.
Q6: What ceiling height is required?
A: A minimum ceiling height of 12 feet (3.6 meters) is recommended. Fan size and placement
can be customized based on building layout and airflow needs.
Q7: How often do these fans need maintenance?
A: Minimal maintenance is needed—usually annual inspection of blades, bearings, and motor components.
Models are designed for long service life even in industrial conditions.
Q8: Are there installation services or support?
A: Yes. We provide after-sales service.
