Fit this Verplas extractor fan condensation trap into the ducting on the exit side of an extractor fan to capture any moisture running down the inside of the duct.

DXiongW Tumble Dryer Vent Hose 4 Inch Aluminum Flexible Duct Hose 5 FT Insulated Ventilation Ducting with 2 Stainless Hose Clamps for Extractor Fan Dryer Cooker. Tip – A simple method to factor in bends in the ducting is to consider each bend as an extra meter of ducting.Vent-Axia provides a complete range of fire stopping products specifically tested with ventilation ducting.Pressure curve examples can be found below. For the rooms with showers and baths it should not be a problem if you can get it go vertical into the attic, then slope down towards the exit. Just run the smooth wall pipe and go with 4' diameter. ![]() Find the pressure curve for the fan to view the capacity based on 48 Pa of pressure against the fan. In rooms with no shower or bath, 25 should be no problem.For example 20 meters of ducting in this example would equate to 48 Pascals (Pa). Multiply this figure by the number of meters of duct in your system.The horizontal line that you plot is approximately the pressure loss per 1 meter of straight air duct in this example that is 2.4 Pascals (Pa).Find the intersecting point of this line and the airflow of the fan in m3/hr, which for this example is 500 m3/hr.Select the line that matches your duct diameter (in this example we will pick 200mm).For the purpose of showing an example we will look at a fan that has an extraction rate of 500 m3/hr and 200mm diameter ducting. Both of these pieces of information are readily available for each model on our website. In order to work this out we just need to know the freeflow extraction rate of the fan (advertised in m3/hr) and the diameter of ducting to be used with the fan.

The below shows a graph which can be used to calculate pressure loss in flexible ducting per 1m of stretched flexible ducting. Bathroom / Kitchen extractor fans are available in sizes 100mm to 150mm as standard, suitable for mounting through the wall or ceiling. Ideal for use with 4 Inch/100mm Bathroom & Kitchen Extractor Fans. But First – How to Calculate Pressure Loss in Flexible Ducting? Manrose 100mm Aluminium Flexible Ducting 10M. Its now been suggested that we should consider f removing all the existing plastic ducting in the loft, replacing it with flexible ducting and an in-line fan.
