Aralco SVEA Slimline
Trickle Ventilation System

The Aralco Slimline SVEA slot ventilator can be surface mounted on all types of windows and is available in any size and finish for slot heights up to 12mm.

Typical applications could be conservatories, or other rooms where ventilation is required to avoid excess condensation

The SVEA vent allows for upward ventilation which avoids excessive draughts and is available with controllable ventilation

A special hood offers weather protection and is available with 2 types of fly screen apertures of either 3 x 4 mm or 6 x 8 mm (for domestic fuel burning applications)

Technical information, drawings and specifications are available upon request or can be downloaded from www.aralco.be
Slimline Trickle Vent EA
Document F - Introducing EA

Our strong performing aluminium trickle vents have been especially developed to meet the requirements of Approved Document F - Means of Ventilation (April 2006 UK).

The Part F (UK) document typically requires 2500 Equivalent Area (EA) for kitchens, utility rooms and bathrooms and 5000 EA for habitable rooms (depending on the ventilation system applied).

EA better reflects the volume of air that will flow through an opening for a given pressure difference.

Trickle vents also need to be controllable and the EA value is clearly marked on the vent

Gas ventilation applications continue to use the "Free Area" (FA) calculation
