Ducting Condensation Trap

Ducting Condensation Trap

Product Part Number

• 100mm PVC Condensation Trap - CD100
• 125mm PVC Condensation Trap - CD125

Description

For Control of condensation/moisture In ducted ventilation systems

Condensation will occur when warm, humid air extracted from the bathroom, shower, kitchen or utility room hits the cooler surface of your ventilation duct.

If the extracted air is significantly cooled and you have a vertical pipe the moisture will condense back to water and become trapped in your ducting, potentially causing damage to the fan and property.

Systems using Roof Vents or Ducting rising vertically carrying extract air to outside benefit with the use of a condensate trap, this is to prevent any moisture forming inside the ductwork, dropping back down and into the fan unit.

This should then be connected to a suitable soil vent pipe using a 21.5mm overflow pipe. 

Constructed of PVC

Compatibility

Compatible with most manufactures including

Performance

Solid Rigid ducting is suitable for use in all buildings to provide superior airflow performance vs. comparative size rectangular or flexible PVC or Aluminium duct. Suitable to use in compliance with Part F Building Regulations.

Installation 

Fit the condensation trap on a vertical pipe between the unit and outside used for air discharge (extraction) - if the pipe is horizontal install a small fall to the outside and the trap will not be required

To provide the best performance in airtightness and durability we recommend You provide greater mechanical strength to a joint by using a combination of Plastic Ducting Sealant and Aluminium Duct Sealing Tape

1. Apply Duct sealant to the male fitting
2. Push together
3. Apply Aluminium Duct Sealing Tape over joint

Alternatively, you can use self-sealing fittings that speed up the time taken by up to 70% and can be easily dismantled

Insulation of Ductwork

It is important that any ducting located in a cold area (e.g. loft space) to be insulated. The insulation needs to be the equivalent of 25mm thick and have a thermal conductivity of 0.04W/(m.k) or less.

This ensures that condensation doesn’t form due to the difference in air temperature inside the duct when compared to the air temperature in the cold space.

If you don’t have a loft space there is still a need for insulated ducting on the intake and exhaust legs, as they will be carrying cold air in a warm space. The level of insulation can be achieved by wrapping PVC duct in a layer of 25mm duct wrap that has a silver foil face on a 25mm Rockwool

It is also worth noting that foil wrap with air bubbles (bubble wrap) is no longer applicable in building control regulations

Sizes

Ducting Condensation Trap is available in 100mm,125mm,150mm if you require larger ductwork we recommend you use Metal Spiral ducting and fittings due to superior strength
