Clamp Together Ducting: Innovation In Exhaust Duct Installation

Traditional installation of round duct for exhaust systems requires the use of screws or rivets to assemble the components. Working with heavier gauge or alloy materials such as stainless steel is labor intensive and costly when you consider the number of drill bits, rivets, and screws required.

These older systems also require an excessive amount of time and material to modify or redirect if that becomes necessary. all of the screws and rivets need to be removed, then replaced when the modification is finished.

Enter the future with clamp together ducting

Clamp together ducting requires no rivets or screws to connect exhaust duct components. As its name implies, duct and fittings are connected by clamps. Both straight duct and fittings have a flared edge for greater stability and are available in a variety of standard duct sizes.

Clamp together duct creates a complete seal with the use of o-ring gaskets at each connection point. These thin rubber rings are compressed between the surfaces of two duct components when the outer clamp is applied to join them together.

While rubber o-ring gaskets are suitable for most exhaust applications, o-rings made from silicon and other materials are available for exhaust systems that carry caustic substances that could cause degradation of rubber gaskets.

What kinds of materials can clamp together ducting handle?

This type of exhaust duct can handle the same types of applications that typical systems can accommodate, including:

Dust collection

Dust may be produced from a specific operation at the location of the exhaust system, or collected as ambient dust from the entire work site. This can include industrial applications such as paper and plastic packaging, and agricultural use such as grain handling.


 Paint spray from painting booths.


Fumes from welding operations or paint and solvents.

Fuel exhaust systems

Machinery that burn oil or gas can be vented through these exhaust systems.

What kinds of materials can't be vented by clamp together ducting?

This type of system can't handle heavy concentrations of liquids (it is not pipe). It also can't be used for pressurized collection systems, which means that material is forced into the duct system. This type of pressure requires the use of bolted or welded flange connections that can handle the stress with less danger of joints blowing apart from a buildup or obstruction in the duct system.

Clamp together ducting works with exhaust systems that blow materials out of the duct, through an exhaust fan in a roof.
