Fabric ducting technology for uniform air flow by Smooth-air Products


In the complex world of commercial ducting and HVAC systems, an issue can be easy to notice but hard to pinpoint. A professional team will spot the problem and supply the appropriate response.

Commercial kitchens produce smoke, steam or airborne grease that needs to be captured and removed, says Smooth-Air HVAC product manager Paul Shaw.

"However, restaurants often add more cooking hoods or heat-producing appliances that skew the ability of the HVAC to perform to specifications.

"In this restaurant, smoke and food odours from the kitchen were wafting into the dining room because turbulence from a high-velocity HVAC supply diffuser prevented the cooking draft hood from operating effectively. The problem was solved when traditional ducting was switched for two D-shaped fabric diffusers. The resulting even output changed the kitchen air pressure from positive to negative, resulting in cleaner air for the dining area."

With DuctSox Fabric Air Dispersion Systems, the air is discharged more evenly along the entire length of the duct, providing consistent and uniform air dispersion in the occupied space, says Shaw.


Lightweight and custom engineered to specific requirements, fabric damper systems come with a 10-year warranty. They are easy to maintain and can be washed in a commercial washing machine. The DuctSox System can be coloured and silk screened to precise customer requirements.

This is just one of the many advanced ducting and HVAC solutions offered by Smooth-Air.
