How Much Maintenance Does an HVLS Fan Require?

High volume, low speed (HVLS) fans are a cost-effective way to cool large industrial spaces, and require very little maintenance. Unlike costly air conditioning solutions that require quarterly service and inspections, HVLS fans are built for low maintenance reliability.

While HVLS fan manufacturers may differ in their maintenance recommendations for specific fan models, a facility manager can expect to perform maintenance that consists of inspections, verifications, and cleaning of HVLS fan parts annually.

What’s not required

VividAir’s Z-TechTM HVLS fan is built with durable, high quality materials that meet the needs of the challenging industrial environments where they’re installed. There’s no oil to change, nothing to grease, and no belts or fluids to maintain, because the gear box in a Z-TechTM is lubricated for the life expectancy of an HVLS fan.

The air scientists at VividAir have designed the Z-TechTM to perform optimally with minimal maintenance. Our best practices for HVLS fan annual maintenance have been developed with input from our engineers and installers with decades of industry experience.

What we’d recommend

Each of our HVLS fan products will come with a product-specific guide and maintenance recommendations. Here are a few of the tasks we recommend performing on an annual basis:

· Visually inspect the fan, including the hub, blades, and Z-TechTM leading edges for signs of damage or unusual wear. Regular visual inspections are important to identify any potential issues or abnormalities.

· Check the fan mounting structure and fan level and plumb. This maintenance task helps identify any misalignments that may occur over time, and ensures continued safe, balanced operation.

· Verify guy wire tension. Guy wires are used to support and anchor the fan. Over time, these wires may experience tension changes due to environmental conditions or other factors. By regularly checking and adjusting the guy wire tension, you can prevent potential issues such as excessive vibrations, fan wobbling, or structural damage.

· Verify hardware connections, cable connections, blade connections, and electrical connections.

· Check the integrity of the fan safety system by verifying the hardware is tight and the straps show no signs of wear.

· Check the gearbox performance and operation to ensure that the fan turns easily by hand in both directions, with no unusual noises or interruptions of smooth travel.

· Clean the fan with a mild detergent and/or clean water to remove build-up. Regular cleaning is recommended to maintain the performance and efficiency of HVLS fans. Dust, debris, and other particles can accumulate on the blades and affect airflow.
