Pool Design Tip: Why Use Fabric Ducts?

There are many benefits to using fabric duct.  It’s less expensive than metal duct, easy to install, and lightweight. It won’t corrode and can be ordered in practically any color. You can also take it down and wash it. Our systems are also constant volume supply air, so there are no concerns about fans cycling off and ductwork deflating.

But fabric duct requires special consideration. The material grade must not “leak air” and diffusers need to be sewn in. Like a metal duct, the diffusers need to be in locations where they’ll contribute to good air delivery, and they need to have proper throw distance to get air into the breathing zone.

A good rule of thumb to remember is, if you wouldn’t do it with metal duct, don’t do it with fabric duct either. When using fabric duct, all the same air distribution and duct design rules apply. You must ensure supply air is delivered to the correct zones or it will result in indoor air quality problems. The duct still needs diffusers and nozzles in order to direct air, so don’t use duct that only has holes for air delivery.

Whether for a new project or a retrofit, fabric ducts absolutely deserve consideration because of their effective, durable and affordable function. One last note – do not hang them with stainless steel hardware. The stainless steel they use does not perform well in indoor pools.
