What is HVLS?

HVLS stands for "High Volume, Low Speed" and is a classification of ceiling fan. HVLS fans differ from traditional fans in that they move a large amount of air at a low speed, whereas most fans rely on high speeds for their air movement. Because HVLS fans do not need to work as hard as traditional fans to provide airflow, they are much more efficient and cost-effective than several smaller fans.

 

Can HVLS fans help with humidity?

HVLS fans are very effective at reducing the humidity in a given space, which can not only greatly elevate worker comfort and product quality, but can also improve worker safety by aiding with potential hazards such as sweating slab syndrome.

 

What is my order status? Can you provide tracking information?

For Sales orders, please reach out to your MacroAir Sales Representative at (866)668-3247 option 1 with your order information and they will be able to update you. For warranty orders, please reply on your ticket email thread, or call us at (866)668-3247 option 2 to speak to Technical Support. Please have your ticket number ready for quick reference.

 

What is the warranty on my fan?

The warranty on an HVLS fan varies by manufacturer and ranges from a few years to decades. Some manufacturers reduce the warranty in half if another service provider installs their fan. Other manufacturers offer a full warranty regardless of who installs it. MacroAir offers mechanical warranties up to 15 years and electrical warranties up to 10 years, regardless of who installs it.

Warranty information for current fan lines can be found on our website here. For warranty information on older products, please reach out to Technical Support at (866)668-3247 option 2 with your original Sales Order Number or serial number of your fan and we will be able to assist.

 

Where can I find the installation manuals or specifications for my fan?

Installation manuals, specification sheets, and other documentation for current fan lines can be found on our website here. For documentation on older fans, please reach out to Technical Support at (866)668-3247 option 2 with your original Sales Order Number or serial number of your fan and we will be able to assist.

 

How do I mount my fan? Is C or Z purlin mounting acceptable?

Our installation manuals here contain guidelines for common mounting applications, such as i-beams, glulams, and unistrut span mounting. You cannot mount a fan directly to a beam that does not meet the minimum width requirements outlined in the manual.

C and Z purlins require the unistrut span mounting method. We recommend getting in touch with Unistrut for advice on spanning and mounting. Never mount the fan to a single purlin, truss, or bar joint.

It is recommended to always have a structural engineer approve your mounting method, especially if it is a mounting method not covered in the MacroAir installation manual. MacroAir cannot offer any mounting guidance other than what is covered in our manuals.

 

How do I schedule a service call?

To schedule a service call, please submit a support ticket here.

 

Do you comply with the Build America/Buy America Act?

Yes we do! Please view the relevant documentation here.

 

Why is the motor cable 25 ft on AirVolution/AirLegacy Series but 50 ft on an X Series?

The X Series uses a different motor and VFD configuration that allows for longer cable lengths.

 

Can I install a motor cable longer than the standard provided length?

Longer lengths may be approved depending on the application and fan model. In order to maintain the warranty of the fan, the length increase must be approved by MacroAir in writing BEFORE placing a fan order.

 

I ordered 240/1PH but received a 3PH motor. Did you mess up my order?

MacroAir uses 3-phase motors regardless of input power. If you read the control panel, you will notice that it is set up for single phase input, but outputs 3 phase power to the motor.

 

I ordered my fan for 240V 3PH, but I need a different voltage now. Can I change the parameters?

Changes between voltages are hardware changes and have nothing to do with parameters. You will need a new control panel in the correct voltage.

 

What are your fans’ CFMs? When will numbers be published?

CFM Numbers for our HVLS fans will not be available until a regulatory body mandates that every HVLS fan manufacturer adheres to the same standards of calculating CFM. This prevents comparison of legitimate CFM numbers to numbers that are obtained from dishonest or outdated calculation methods.

The Lincoln Street fan has 10,155-15,150 CFM of airflow depending on the diameter.

 

I ordered a 5' drop length, but only received a 3' tube. Did I get the incorrect part?

It is important to understand the difference between the terms drop length and extension length. The drop length is the total distance between the top of the mount and the bottom of the blades. The extension length is the length of the tube itself. The drop length takes the height of the motor and mount into account to ensure that your fans hang at the specified level. For example, the standard 8'-18' AVDX drop length is 35.5", which uses a 13" extension tube. Below is a drawing which illustrates the difference. 

 

 

Can I have a drop length over 10’?

Drop lengths over 10’ may be possible depending on the fan model and mounting method. Please reach out to our Sales team at (866)668-3247 option 1 to discuss.

 

Can I cut my drop length in the field if it is too long or source my own tube from elsewhere?

Modifications or substitutions to drop lengths in the field will void the warranty of the fan. If a different length is necessary, please reach out to our Sales team at (866)668-3247 option 1 to order the correct length.

 

What size breaker should I use for your fans?

There are many factors that go into sizing a breaker that MacroAir cannot account for. This is a decision that the installing electrician will need to make based on the amp draws we provide in our installation manual and specification sheets here.

 

Can I install more than 1 fan on my breaker?

Assuming the breaker is sized correctly for more than one fan, and all national and local codes are adhered to, it is acceptable. However, having each fan on its own breaker allows for easier troubleshooting if any issues arise.

 

What size fuses does my fan need?

All MacroAir fuse holders accept class CC or class gG fast acting fuses.

AirVolution, AirLegacy, and AVDX fans ship with fuses inside of the control panel. For fans that utilize a fused disconnect switch, such as the AVD370, AVD3, and AVD5, please refer to the installation manuals here for fuse recommendations. For documentation on older fans, please reach out to Technical Support at (866)668-3247 option 2 with your original Sales Order Number or serial number of your fan and we will be able to assist.

 

What size/gauge of wire do I need to run to your equipment?

MacroAir cannot provide guidelines on sizing wires, as this differs greatly from application to application. The appropriate wire size will need to be determined by the installing electrician using the amp draws given on our specification sheets here.

 

If I need smaller blades, can I cut the existing ones in the field?

Cutting blades in the field can lead to many issues and will void the warranty of your fan. Certain motors are only designed to work with certain blade sizes and may not work correctly with a smaller diameter. If you need a smaller diameter, please reach out to our Sales team at (866)668-3247 to assist with getting you the desired diameter.

 

Why don't your fans have winglets?

Winglets negatively impact the performance of an HVLS fan by increasing the amount of energy the fan uses and making the fan wear out faster. The small, curved caps added to the edge of some HVLS fan blades have sparked much debate. Some companies add winglets to capture and move more air, but it actually hinders a fan’s performance.

 

Some HVLS Fans have 3 blades, some have 5, some have 6, and some have 10. What's the difference?

The differences are the amount of airflow the fan can produce, the energy it uses, and how it affects your building’s infrastructure. Different manufacturers have varying beliefs on how many blades are best for specific situations. However, with today's technology at play, fans with fewer blades move an extreme amount of air and are more energy efficient because of the lighter weight.
