Product Introduction

Two galvanized rectangular end flanges are joined by a sewn blue coated-fabric sleeve, creating a hollow air passage with a flexible wall section between rigid duct connections.

Key Features

Flexible fabric interrupts direct vibration transfer.

Twin flanges provide defined bolted interfaces.

Coated fabric limits air leakage through the sleeve.

Corner holes support repeatable alignment.

Customer Product Concerns

Rigid duct connections can transmit fan vibration and stress adjacent sheet-metal joints.

Equipment vibration travels into ductwork.The fabric sleeve decouples limited movement.

Misaligned ends load rigid joints.The flexible span accommodates small installation offsets.

Uncoated fabric leaks air.A continuous coated textile forms the air barrier.

Weak edge attachment can peel.Fabric edges are continuously retained at both flanges.

Typical Applications

Fan discharge jointsAir-handler connectionsCleanroom supply ductsExhaust equipment transitions
