Product Information

If a product fails after six months of receiving the item it is considered a warranty claim and is the responsibility of the buyer to pay for the return postage. We will then dispatch a free-of-charge replacement once the original has been received and tested. Book a DPD Return Here They are either pressed or fabricated. The majority of pressed reducers are in the size range upto 315mm diameter, however some sizes within this range (which are classed as non-standard) will be fabricated. Diameters from 355 upwards are fabricated i.e a specialist metal worker will make them with there own fair hands.

Be aware that a negative change in diameter can have an impact on the airflows within the duct system, as the air is forced through a smaller area it can create more resistance and more noise. Reducers up to 315mm diameter are pressed reducers (for Standard Sizes), 355mm and above are fabricated reducers.Please Note: Under current regulations, Flexible Adaptor Couplings and Reducers are prohibited for use on adopted drainage systems. Straight Connection couplings with a shear band should be used instead to ensure the connection is protected under earth loads. If a connection needs to be made between drainage pipes that have different outside diameters, combine a Shear Banded Coupling with a Flexseal Bush or Multibush. Flexible Drainage Adaptors and Reducers offer a versatile solution for connecting pipes of different diameters. These special couplings are available in a variety of size ranges to suit most applications and are easy to install without the need for special tools or equipment.

I have used Fastlec three times each time I have found them to be efficient fast and happy to give you information on their products." In short, it all depends on how your ducting system has been designed. It is possible. There are many variables, the duty of the fan, where the reducer is situated within the duct run etc, etc.A concentric reducer is a basic peice of metalwork that is used as a duct adapter to decrease (or increase) diameters of a duct system. A concentric reducer, is shaped like a cone and the centre line is directly in the middle of the two diameters. It is advisable to only use reducers to make adaptations to the duct diameter if it is absolutley essential. What is the most common common size of ducting reducer? An eccentric reducer has an edge that is parallel to the connecting pipe and creates an offset in the centre line of the ventilation duct run.
