Ventiflex H&V Ducting Hose

Features

Ventiflex: is a tough reinforced, high performance airduct with extremely low air friction-loss due to its smooth bore.

This type of duct fits to high, medium and low velocity heating, ventilating or air-conditioning systems. Perfectly suitable for industrial smoke or fume removal.

Construction: spring steel wire helix PVC-coated and bonded to PVC-coated fabric of fibreglass or polyamide.

Applications: Ventiflex is widely used for industrial applications, such as welding fume and non-abrasive powder extraction.

Typical applications: as a connector from an attenuation box to the outlet.

In modular ceilings: as runouts from mechanical ventilation or packaged systems to air outlets (replaces fabricated elbows and fittings in confined or problem areas).

As connectors between misaligned ceiling outlets and supply ducting, reducing transmission of vibration and noise.
