Flexible Duct Hangers - The Right Way To Hang Flexible Air Conditioning Duct

An important issue today in relation to the efficiency of air-conditioning systems

is the hanging of flexible duct so as not to impede or restrict air-flows. FDH - Flexible duct hangers have a unique adjustable design which allows ease of correct installation of flexible duct to help solve this problem.

Everywhere there's a commonly seen problem in a large amount of channeled aircon systems, that problem, inefficiency. When aircon systems are installed, be they business, commercial or domestic systems, issues arise which cause power consuming inefficiency like thermal loss. This inefficiency derives from the limitation of needed / designed airflow rates. The source of this problem is the wrong installation of flexible channel.

Now , flexible channel is being hung using assorted non-compliant materials and techniques - if in any way. A few of these materials are ; blue plastic packing strap and a piece gutter guard, tape, foil insulation tape, string and strips of wire to cite a couple. The usages of these materials can and occasionally do cut into the foil or plastic outer jacket of the channel permitting air leaking. The coiling, twisting, squashing and kinking of the channel creates not only limitations in the airflow but also poor thermal efficacy of the insulation. In some extraordinary cases, the over pressurisation of air in the channel can cause exaggerated leaking or "blow-out" of the channel, or overworking of the fan leading to possible breakdown and high-priced service call.

There is an industry practice to hang flexible duct to various standards, in America for instance, the standard is called the S.M.A.C.N.A. Standards. Where in Australia it is a requirement of Australian Standards AS4254 (2002), which is almost a mirror image of the American Standard. Section 2.8.5 of AS4254 gives a brief overview of what is required. This section will need to be updated in 2009 to incorporate the new Building Code of Australia (BCA) Section "J" duct insulation requirements which are being brought into force this year. The BCA now requires a minimum duct insulation thicknesses for ducted air-conditioning systems, be they rigid type or flexible duct type. The minimum insulation thickness is now 38mm, whereas formerly it was 25mm.

Employing a correct methodology of installation as laid out in the standards and a simply alterable flexible channel hanger material could guarantee these issues being raised. When flexible channel is hung properly, the air conditioned air flows unfettered to the diffuser to uniformly dispel the warm or cool air as needed. The wear on the fan coil unit is reduced as it is not working as hard against a proscribed airflow trail. An effectual system would in turn use less power, saving money in operation time and servicing breakdowns.

The FDH - Flexible duct hanging system is designed as an essential way to hang and support flexible air-conditioning duct and lightweight associated accessories. This registered design allows height and diameter adjustment according to the chosen hanger length. Installation is easy with various methods of attachment giving the FDH - flexible duct hanger versatility and reliability. The material used in this unique design has been tested to Australian Standards AS1530.3, achieving a 0,0,0 rating.

It has other constructive properties like being UV treated, has chemical and anti fungal Resistencia, is intensely sturdy and has particularly high tear strength. Fixing strategies like a straightforward lap-over beam design, market available masonry or nylon anchors, steel or timber screws all provide a powerful, trusty way of fixing off. Available in a "do it yourself" roll and buckle combo or custom made lengths to your necessities, the decision is yours! For more information visit : http://www.flexibleducthangers.com.au.
