Questions and answers of the customers

Does it have a robber seal?
-
A Good morning Andrea. It has a rubber seal where the shutters close, but no rubber seals on the outside.Kind regards, Marc
Does this just sit inside the spiral ducting, or is a connection needed on either side?
-
QDoes this just sit inside the spiral ducting, or is a connection needed on either side?answer nowA Good morning Chris.This item does indeed fit between 2 pieces of ducting, as it is a male fitting, whereas spiral ducting is female.Kind regards, Marc.
Does this need to be used like a coupler between two pieces of duct or is it designed to be fully pushed inside a single piece of duct? Is there a rubber sealing ring around the outside to achieve a good seal between this and the duct (like the Safe system)?

QDoes this need to be used like a coupler between two pieces of duct or is it designed to be fully pushed inside a single piece of duct? Is there a rubber sealing ring around the outside to achieve a good seal between this and the duct (like the Safe system)?answer nowA Hi Martin, Thanks for your question.Male Fitting - Will fit inside the i-sells range of 150mm Spiral DuctingIt can be pushed down a single length.There is not a rubber seal - so its not part of the safe system it is designed to be a tight fit for the spiral ducting.I hope that helps to answer your question.Best RegardsChris
Can this be used with 150mm plastic duct and can it be mounted vertically? I accept some fettling may be required.

QCan this be used with 150mm plastic duct and can it be mounted vertically? I accept some fettling may be required.answer nowA Hi Martin, and thanks for your question. Yes it can be used with plastic ducting, and it can be sited vertically or horizontally. It is a better backdraught shutter than the plastic one to be honest.Kindest regards, Marc.

Morning,
If I was to install one of these into a fixed piece of ducting connected to a domestic cooker extract unit would the air movement be strong enough to open the shutter
Many thanks

Can this backdraught shutter be mounted in a horizontal position? Thanks!
-
A Hello Francis Thank you for your question. Yes it can be fitted horizontally.
I cant see any difference between this shutter and others available on line at a quarter of the price as details are in short supply.
Perhaps you could advise me of the differences as this is being installed in a domestic MHVR system

The product you are looking at is made from pre-galvanised steel with spring-loaded vanes of aluminium. We also do plastic backdraught shutters. They both do the same job and you have a two choices to choose from.
