Airflow has a dedicated hub that explains the reach and effect of the ErP Eco Design Directive. The hub breaks the ErP Directive down so that it is easy to understand and covers both residential and industrial fans. You can find the hub here.
The ventilation industry is governed by a number of different parts of legislation and Building Regulations, some of which are found below. As of 2015, all ventilation systems must adhere to the ErP (Ecodesign) Directive. You can learn more about ErP in our dedicated hub.

You can easily adjust the timer by turning the timer either anticlockwise to decrease the time (minimum of 4-5 minutes) or clockwise to increase the time (maxiumum of 45-50 minutes).
L terminal is for permanent LIVE wiring. T terminal for SWITCHED LIVE wiring.
In most ceiling installations, taking hot baths and showers will produce hot, humid air that will rise. Once this humid air reaches the cold loft space, it will cool and condense back into water and trickle down the pipe. To help combat water damage, it is good practice to ensure that a condensation trap is fitted to your system. Condensation trap are sold separately from the main unit, please contact us so that you will receive the correct condensation trap for your unit.
Another way to combat water damage is to ensure that the unit's timer (if applicable) is turned up to run on for at least 20 minutes after the fan has been switched off.
You can indeed change the module of your iCON at a later date - but your iCON may require additional wiring to do so. You can find the full range of iCON modules here
MVHR (Mechanical Ventilation with Heat Recovery) is the process of continuously ventilating your home. MVHR units supply your home with fresh, clean, filtered outdoor air whilst removing the stale, polluted air. MVHR systems can also help you save on your energy bills as they extract the heat of the air being removed from your home to pre-warm the incoming outdoor air. At no point do the airstreams mix.
MVHR is different from normal ventilation systems because it recovers the heat that would otherwise be lost and uses it to pre-warm in the incoming air. This means that you can see a reduction in your heating bills and the carbon footprint of your home, as you shouldn't need to have your heating on for as long.
Summer bypass is process whereby the heat exchanger is bypassed during the summer months. This only takes place once the temperature sensor reaches a predetermined temperature and is designed to prevent overheating within your home.
We recommend that the filters are changed at least once a year. However, depending how polluted the area around your home is, they may need to be changed more often.
Our standard fans are suitable for clean air with an ambient temperature of up to 40oC.
We have a range of high temperature fans that are suitable for use up to 250oC. Please contact us for more details.
Yes we do. We will have to look at the fan requirements prior to commissioning. Please contact us for more details. Please note there will have to be a minumum order quantity which is dependant on each particular fan.
There are significant advantages in using dilution fans instead of conventional flue stacks as they offer the opportunity for the flexible siting of boiler and water heaters within the boiler room, and the elimination of unsightly external, or expensive internal flues. Based on efficient and quiet double inlet centrifugal fans they are capable of overcoming the system resistance of flue duct runs, and, with the built-in self proving safety switches safety is not compromised in the event of fan failure or flue blockage.
