|CVALF - ALUMINIUM FIRE RATED FLEXIBLE DUCT|
Fully flexible, high quality, un-insulated aluminium laminated duct for general use in exhaust and fresh air ventilation systems.
Ultra-tough and airtight with a smooth core for low friction loss and lower operation costs.
The flex is constructed with a spring steel wire helix, fully encapsulated in a polyester, aluminum foil, and polyester tri-laminate.
Fully extend ducting, then cut to exact length required using a sharp knife and pliers/wire cutters.
To fix flex to spigots/connectors we recommend the strangle banding and jubilee clip system.
All diameters listed refer to duct size.
The flex is oversized to slip over the duct.
To calculate the length of flex required please see chart below.
