The Lenworth Guide to HVLS Fans: Information, Benefits and Models

 

Guide to HVLS Fans: Here is what you need to know

From warehouses, manufacturing plants and automotive dealerships to breweries, restaurants, atriums and more, large facilities of all types constantly contend with how to use energy more efficiently. Whether it’s using A/C in the summer or heating in the winter, this issue goes beyond saving on energy costs. It’s equally a matter of employee safety, comfort and productivity.

The fact is, large facilities will struggle with all these issues in hotter and colder months if they cannot effectively circulate and distribute treated or ambient air to where it needs to go. With the help of HVLS (High-Volume-Low-Speed) Fans, large facilities can easily circulate and destratify air in both ambient environments and ones using heating and cooling systems. Read on to consult our guide to HVLS fans, how they work, how they can benefit large facilities and the various models that Lenworth carries.

What is an HVLS fan?

HVLS Fans are large ceiling fans that move large quantities of air at lower speeds. The low speed ensures whisper-quiet operation, even as these fans distribute and circulate airflow in large spaces.

What do HVLS fans do?

In the summer months, HVLS fans provide incredibly effective evaporative cooling and change the perceived temperature in spaces that do not have A/C. In ambient environments, these fans can help spaces feel up to 10°F cooler. If your facility does happen to have an A/C unit, HVLS fans help facilities can raise temperature setpoints and save up to 40% on energy bills without sacrificing the comfort of employees and patrons.

During the winter months, these systems help facilities properly destratify warm air generated by HVAC systems. This destratification process involves redistributing warm air trapped at the ceiling down to the floor level. These large fans work with HVAC systems, supplementing and effectively moving the air they generate to help facilitate heat savings of up to 30%.

What benefits do these fans offer?

Reduced Heating and Cooling Costs

As we’ve mentioned, HVLS fans will help facilities of any size save money on heating and cooling costs. By working in tandem with HVAC systems, HVLS fans help facilities use their energy more efficiently while not sacrificing performance. On their own, these fan systems are incredibly efficient, with units costing pennies per day to operate. These combined benefits will help facility managers take meaningful strides towards saving on energy costs and reducing the overall carbon footprint.

More Comfortable Interior Conditions

In the summer, hot temperatures can decrease productivity and increase the likelihood of errors. When employees don’t feel comfortable in their place of work, it’s easy to lose focus and energy in situations that demand both. Maintaining a comfortable workplace temperature in the summer enhances employee safety, well-being and operational efficiency. The same goes for colder conditions in the winter months. HVLS fans make it easier to create and sustain these comfortable working conditions year-round.

In commercial applications like restaurants, lobbies, atriums, breweries, or automotive dealerships, HVLS fans create ideal internal conditions for all customers, all year round.

What HVLS fan models do Lenworth carry?

Lenworth’s entire line of HVLS fans is manufactured in Ontario for fast lead times, local application engineering and product support. These high-end HVLS fans will all lead to safer, more efficient working conditions in hotter and colder months. Here’s a guide to HVLS fans that we carry:

1. The Altra-Air Sailfin Gearless HVLS Fan

Powerful, durable, quiet and efficient, this direct-drive HVLS fan delivers maximum air circulation in a variety of applications.

Simple Gearless Design: With only two moving parts, this direct-drive unit eliminates any potential oil leaks. It’s lighter, stronger and quieter than traditional HVLS fans and virtually maintenance-free.

A Tapered Airfoil Design for More Efficiency: Enjoy consistent airspeeds and better coverage at less cost. The industry-leading tapered airfoil (or fan blade) that’s up to 10-¾” wide maximizes airflow from the hub to the tip of the fan with a pitch that moves from 16° to a 23° angle of attack.

Advanced Safety Features: This model includes multiple built-in safety features: an unbreakable cast alloy aluminum hub, a steel flat bar restriction system running the length of the fan blade, 3/16″ safety cables, guy wires, airfoil toppers, an integrated 20,000 lumen LED light, and an auto-impact shutoff system.

Varying Sizes & Easy Operation: Available in diameters ranging from 8’ to 24’ for different applications. The remote keypad easily controls power, speed and the fan’s direction.

2. The Altra-Air Sailfin HVLS Fan

While this model does not feature the direct-drive motor, it too creates faster fan speeds, increases airflow and operates at whisper-quiet levels. It also features a durable cast alloy aluminum hub and high-end safety features.

Advanced Airfoil Design: Enjoy consistent airspeeds and better coverage at less cost. The industry-leading tapered airfoil that’s up to 10-¾” wide maximizes airflow from the hub to the tip of the fan with a pitch that moves from 16° to a 23° angle of attack.

Strong and Lightweight: Sailfin airfoils eliminate noise by using a non-linear leading edge to spread noise across a greater range of frequencies. A combination of zinc-coated steel and injection mold fibre-filled polypropylene creates a lightweight, industrial-strength fan blade.

Varying Sizes & Easy Operation: Available in diameters ranging from 8’ to 24’ for different applications. The remote keypad easily controls power, speed and direction.

3. The Jazz Fan

From showrooms and restaurants to office spaces and atriums, the state-of-the-art customizable Jazz Fan is a stylish, comfort-enhancing, cost-effective addition to any space. More than just an aesthetically-pleasing HVLS fan, the Jazz Fan is an example of premium fan design and engineering.

Advanced Design for Efficient Air Movement: The Jazz Fan’s airfoils have an industry-leading, varying-degree angle of attack. Ranging from 6° at the tip to 14° at the greatest point, these blades maximize air movement and minimize power consumption for cost-effective comfort year-round.

Strong and Lightweight: The Jazz Fan’s airfoils eliminate noise by using a non-linear leading edge to spread noise across a wide range of frequencies. A combination of zinc-coated steel and injection mold fibre-filled polypropylene creates a lightweight, industrial-strength fan blade.

Simple Gearless Design: With only two moving parts, this direct-drive unit eliminates any potential oil leaks. It’s lighter, stronger and quieter than traditional HVLS fans and virtually maintenance-free.

Smart & Safe: On-board, pre-wired controls constantly measure fan loads and make real-time energy-saving adjustments. UL, CSA, CE certifications, on-board safety controls, a built-in dimmable LED light, a superior harnessing system & universal mounting ensure safety in any application.

Visually Appealing & Customizable: Choose from a variety of custom finishes: vibrant red, brilliant chrome and more. Enjoy custom textured finishes like rich carbon fibre, rustic barn board, soft leather, and deep mahogany.
