Tecsonic Duct – Acoustic Flexible Duct With Interliner

TECSONIC DUCT – ACOUSTIC WITH INTERLINER

• High quality flexible acoustic ducting ideal for use where attenuation of duct borne noise is required.
• Fire resistant – Tested to and complies with BS476 (British standard 476 fire test)
• Suitable for applications where high strength and flexibility is required.
• Certified acoustic performance – independently tested.
• Complies with HVCA specification DW144.

Tecsonic 400 is a high quality fully flexible acoustic ducting. It is ideal for use in low and medium pressure ventilation and air conditioning systems where attenuation of duct borne noise is required.

• Flexible Ducting
• Fire-resistant – Tested to and complies with BS476.
• Certified acoustic performance – independently tested.
• “S” type includes acoustically transparent interliner
• Suitable for medium and low-pressure applications.
• Individually cartoned 10-metre lengths.
• Complies with HVCA specification DW144.

Construction:

Tecsonic 400S is constructed in a similar manner to Tecsonic 400 but with the addition of an acoustically transparent interliner between the inner core and fibreglass layers. This interliner allows for good acoustical performance yet shields the airstream from the fibreglass and prevents the possibility of fibre migration into the airstream. This feature makes Tecsonic 400S especially suitable for specialist applications e.g. Food preparation, clean rooms etc. Like Tecsonic 400 this construction still provides a highly flexible duct in which bends of 1/2 D radius can be produced.

Specification:

Acoustic flexible ducting for joints or connections shall be TECSONIC 400S. It shall be manufactured with an aluminium/polyester inner core continuously perforated and wrapped with an acoustically transparent interliner. The interliner shall be covered by an overlapped fibreglass blanket with an outer jacket constructed from a reinforced aluminium fabric. The duct shall meet the time requirements of BS476 parts 6 & 7.

Packaging:

Tecsonic 400S is supplied, as standard, in 10-metre lengths. Each length is individually cartoned and labelled. Storage space required is kept to a minimum with a 10-metre length being compressed to 1150mm.

Technical Data:

• Diameter Range: 100mm to 500mm
• Temperature Range: From -30ºC to +120ºC
• Air Velocity: 15 m/s maximum
• Working Pressure: 1000 Pa maximum
• Fibreglass: 25mm thick. 16Kg/m3 density
• Outer Jacket: Scuff-resistant reinforced aluminium laminate fabric
• Colour: Metallic silver
• Standard length: 10 metres

Installation:

Fully extend ducting, then cut to exact length required using a sharp knife and pliers. Pull back fibreglass insulation and tape the inner core to the spigot. Then tape and clamp the outer jacket and inner core to the spigot.
