Industries Introspection: Ventilation Ducting Options


Celina Industries’ has a wide variety of product venues which have been created to serve as many people as possible over the years. At Celina, we believe it is important to hone in on each of those product venues and really dig into the specifics that make up each product line.  Our continuing Industries Introspection Series this week focuses on an area that, again, seems like an ultra-specific topic: Ventilation Ducting.

The Differences Between Ducting Styles

Ducting, as used for ventilation, can be broken down into two main categories based on their construction:

1. Plenum/Duct Socks

Mostly used in agricultural barns and more industrial-style buildings, Duct Socks are lightweight and easy to install. Made from 6.5 oz. vinyl, each duct has the option of either snap clips or grommets for securing in place. Snap clips are the easiest to install, only requiring a single line for the clips to attach to. Grommets, however, allow the ducts to be connected virtually anywhere – rope can be fed through the grommets and then secured to whatever structures are available.

Plenum can be designed with any configuration of vent holes along the length to ensure the desired dispersal of air. Diameters of the individual ducting range from 18” to 24”, with in-between sizing at 2” increments. The ease of construction allows us to create customizable duct socks as well, letting us create product for whatever job you have in mind.


2. Spiral Ducting

These are the ducts most people imagine when the ducting topic is breached in conversation. Spiral Ducting is fabric that winds around on itself, allowing us to create a tube from a single piece of material. As the fabric winds around the stand, it is either heat sealed or sewn; either method is available according to the end use of the product. Air-tight ducts require the heat-sealing method in order to create air-tight welds along the seam.

During the fabrication process, wire reinforcement can be added to the seam areas. This adds structural support, making sure the duct won’t fold in on itself or collapse. Wires can simply be integrated into the seam, or further reinforced with wear stripping that can reduce damage due to wear at various wire locations.

A Ducting Solution for Every Situation

“Apart from looks, why make two kinds?” you may be asking yourself (and rightfully so). In cases such as livestock barns or industrial complexes/offices, the lighter ducting sock is more than enough to get the job done. The easy-hanging design and lay-flat material makes it a staple in simple air distribution systems. Celina employs a Positive Pressure Tube Ventilation Consultant who specializes in the creation and design of air system that use the lay-flat plenum for use in agricultural barns.

Spiral ducting is more often put to specific uses; when used to transport materials instead of air, the wire supports can prove indispensable in keeping the flow from getting stopped up in the process (think vacuuming packing peanuts, for example). There are also various military and industrial systems and processes that require spiral ducting, from aircraft connections to tent ECU systems. This is also the primary method for creating dog agility tunnels, used to train dogs for competitions.
