Round Insulated Multi Layer Composite Non Metal Fabric Compensator Air Duct Expansion Joint
The Round Non-metal Fabric Compensator is a flexible, insulated air duct expansion joint engineered for circular ducting systems. Its multi layer composite fabric body absorbs axial, lateral and angular movement while damping vibration and reducing noise, making it an ideal soft connection for hot air ducts, fume ducts and HVAC pipelines. The fabric body is durable, flame retardant and protected against dust and corrosion. All dimensions are customized to your required duct diameter and installation conditions.
The round fabric compensator compensates axial, transverse and angular movement in circular ducts. It features no thrust, simplified support design, corrosion resistance, high temperature resistance, insulation and vibration damping, and low fluid resistance. It is especially suitable for round hot air ducts and fume ducts, and can be supplied as an insulated multi layer composite version for higher thermal and acoustic performance. Every unit is custom made to order.
The circular non-metal fabric compensator is widely used in round air ducts, hot air ducts, flue gas and soot ducts, HVAC ventilation systems, dust removal and desulfurization ducting, and low pressure industrial gas and air pipelines. It is a maintenance free soft connection for round ducting in power plants, metallurgy, chemical and building services.
