Flexible Forced

Flexible Forced

Schauenburg Lay-Flat Ducting is ideal for positive pressure applications. This is the standard ducting used in hard-rock mines, due primarily to low initial cost and ease of installation. Seams and grommets are welded to be airtight, providing low airflow resistance.

 

Applying our world-wide experience and know-how, we work closely with our customers to make sure they are getting the most appropriate grade of duct to minimize cost and maximize durability.

  • Diameters from 6 inches to 96 inches (150 to 2,450 mm) available.
  • Lengths to 1,000 feet (308 meters).
  • Five different grades to match specific pressure and durability requirements. 

 

Flexible Forced Duct for postitive pressure, with two welded suspension strips. Steel wire cable with button stops welded into the suspension on both sides. Standard diameters 24-94″
lengths made to order.

 

 

 

Tees for any application
