What healthcare professionals and WheelAir users think

“I’ve seen it first hand, the impact that overheating has on someone’s ability to carry out their daily activities and for their general well-being as well. Not just to simply carry out tasks, but for safety, the medical consequences as well, blood pressure, feeling of wellness. It is a significant issue”

Due to nature of my disability, a spinal cord injury, I can’t regulate my body temperature. I feel uncomfortable with any weather over 21 – 22 degrees. This causes all kinds of issues – fatigue, dizziness, nausea, inability to concentrate. However, by using the WheelAir before and after training and matches, my performance improved every time."

WheelAir cools back temperature down by 8ºC in 30 minutes

A flow of isothermal air takes away any excess heat and moisture through convection, conduction and evaporation heat loss, reducing the risks of infection and irritation associated with humidity and temperature such as pressure ulcers and heat stroke. It is designed to reduce exhaustion, pain and discomfort caused by overheating or over sweating.

Frequently asked Questions

Got a query? Check below

How easy is it to replace my current backrest with WheelAir?

The WheelAir is designed to easily replace the backrest of any (rigid or foldable) wheelchair with a canvas sling back. Just remove your backrest (which should be attached with velcro) and leave the tension adjustable straps on the frame. Simply fold your WheelAir backrest over the tension adjustable straps and you’re good to go.

Will WheelAir fit on folding wheelchairs?

The WheelAir backrest is designed to easily replace the backrest of any (rigid or foldable) wheelchair with a canvas sling back. The WheelAir is available in six sizes in order to best match your current backrest width.

Do I need to take my WheelAir off to fold my active wheelchair?

If you have a rigid active chair, the WheelAir can stay on when folding forward the backrest. If you have a folding chair, thus the frame folding in the middle, the fan box needs to be removed, but the backrest can stay on the chair.

Will the WheelAir backrest change my posture in my chair?

Many WheelAir users describe the WheelAir cushion as a more supportive and posture correcting backrest compared to regular sling backs. This is due to the custom blend of high quality viscoelastic foams.

I can’t sweat, will WheelAir still help me stay cool?

It will! WheelAir takes away excess body heat through convection, conduction, and evaporation heat loss. So even if you don’t sweat, the convection and conduction heat loss will still cool you down. Check our Clinical Indications for more info!

I have no sensation below my spinal lesion…how will I feel a difference with WheelAir?

Even without sensation in your back, WheelAir will still keep you feeling cool. Overheating can cause fatigue, muscle cramps, spasms, nausea and other issues that you feel throughout your body. As your body cools down with WheelAir, the feeling of wellness should return, which is how you’ll know its working. The airflow helps reduce body temperature through a process of convection, conduction, and evaporation heat loss.

Is the WheelAir like air conditioning for your wheelchair?

The WheelAir is not “air conditioning”, so it does not cool down the air temperature before it goes through the backrest. But it does cool you down through convection, conduction, and evaporation heat loss!

It’s really hot where I live, does it still work?

WheelAir still works when it’s really, really hot outside because the airflow helps with cooling down through evaporation and latent heat transfer. Ideally, WheelAir works best when humidity is below 70%. The Clinical Indications show how much you can cool through each setting, in each environment ranging from 10˚C to 37˚C.
