Window Trickle Vent Set - 5000EA

The 5000EA window trickle vent is a powerful and versatile window ventilator, engineered to deliver significantly more Equivalent Area (EQA) performance than traditional 4000mm² ventilators of similar length. Fully compliant with F1 building regulations, it is suitable for both new build and replacement sectors and is compatible with all major window types, including UPVC, Aluminium, and Timber.

Key Benefits:

• Achieves high airflow efficiency, outperforming traditional 4000mm² ventilators.
• Uses two compact 204mm x 13mm slots, reducing routing machine times and minimising waste materials.
• Manufactured from ASA material for excellent UV colour stability and strong mechanical durability, ensuring long-lasting performance in all conditions.
• Smooth, user-friendly opening with a positive closing action.
• Innovative “link” system allows the closure plate to be positioned to reduce draughts while directing airflow away from occupants.
• Unique split closure plate enables partial (50%) opening, offering flexibility and further ease of use.
• Rounded ends make it suitable for timber window installations.
• Available in screw fix (no end caps required) or clip fix (fast, simple installation with pawls).

With powerful airflow, flexible installation, and endless finish options, the 5000EA window trickle vent is the ultimate choice for modern, high-performance ventilation.

What Does Equivalent Area (EA) Mean?

Equivalent Area (EA) is the standard way of measuring how much air a ventilator can let into a room. Unlike the older “free area” measurement, EA takes into account the shape and efficiency of the vent, giving a much more accurate picture of real airflow performance.

The higher the EA, the more fresh air the vent can provide. For example:

• 2500 window trickle vent delivers 2500 mm² EA.
• 5000 window trickle vent delivers 5000 mm² EA.

This makes it easy to choose the right size ventilator to meet Building Regulation requirements for background ventilation, while ensuring comfort and energy efficiency.
