Nowadays, HVLS industrial fans are increasingly widely used and are suitable for the workshop, logistics, warehousing, public places (bus and railway stations, docks, airports, stadiums, commercial streets, shopping centers, the school halls, gymnasium, leisure clubs, Internet cafes, government affairs halls, etc.), agriculture and animal husbandry (planting, livestock farm), effectively realizing the integral space flow loop, beautiful and durable without occupying space.
Here are some FAQs of HVLS industrial fans.
1. What is HVLS for HVLS fans? How long has it been used?
Short for "High Volume, Low Speed." HVLS fans refer to huge variable-frequency controlled fans, often referred to as large industrial fans.
Invented by an American in 1998, the oldest HVLS fan has been running for about 15 years.
2. Is the use/maintenance cost of HVLS industrial fans high?
The normal service life is more than ten years, and there is basically no maintenance and low costs in the process of use.
3. Airflow direction of HVLS industrial fans?
The air is inhaled from the upper part of the fan blade and diffuses toward the ground in a cone shape. Under rational conditions, the effective coverage radius can even reach more than 30 meters.
4. The role of the spoiler
The spoiler of the HVLS industrial fans helps the fan generate more air volume while effectively reducing wind noise.
5. The relationship between wind pressure and wind speed?
The wind pressure is related to the diameter and speed of the fan. To eliminate hot and cold delamination, the wind speed should reach more than 0.2m/s. Wind speed above 0.9m/s will make people feel cool.
6. What are the common building structures and installation methods suitable for installation?
I-beam (H Beam, I Beam), steel mixed Beam, spherical grid, etc.
7. Will obstacles affect the use of HVLS industrial fans?
It will affect the airflow direction and coverage area.
