Harsh Environment Suspension System

FabricAir introduces the Harsh Environment (HE) Suspension System.

Originally published: 1/5/2023

The Harsh Environment Suspension System is the fabric HVAC duct industry’s first and only hot dipped galvanized (HDG) coating for safely protecting critical weight-bearing suspension components from corrosion in commercial/industrial building harsh environments.

The HE Suspension System is designed for use with FabricAir’s proprietary anodized aluminum H-Rail suspension products and consists of HDG threaded M8 steel rods, nuts, washers, threaded rod couplings and rod/H-Rail connectors. The specially-designed, proprietary connectors accept M8 (5/16-inch) rods, but adapt to the M6 (1/4-inch) diameters required for standard H-Rail connection. The HDG coating’s minimum 40-micron layer is thicker and more protective than most competitive coatings. Consequently, the male and female threads of the rods and receptacles are cut strategically to facilitate smooth turning.

The HE Suspension System complies with North American building standards. The HE suspension system and H-Rail are both designed to endure a minimum of 30 years in a natatorium. Natatoriums are often classified under corrosion categories of C4-C5, because they’re one of the most challenging engineering environments due to inherent high humidity, chloramines and gaseous pool sanitization chemicals. Food processing, waste water treatment, chemical and other corrosive environment facilities and are also ideal applications for the HE suspension system.

FabricAir recommends combining the HE Suspension System with Combi permeable fabric duct for a total HE air distribution system. Combi’s polyester material is corrosion resistant and its permeability prevents duct condensation formation. Optional antimicrobial fabric treatment is also available for food processing, pharmaceutical and other applications where mold, mildew and other microbes potentially grow. Combi is available with all FabricAir air distribution vent designs.
