Aralco MultiCoust EPC
Trickle Ventilation System

The Aralco MultiCoust EPC is a thermally broken, self-regulating and sound reducing ventilator. It combines sound reducing characteristics with the same compactness and benefits of natural ventilators

MultiCoust EPC has 3 different airflows, 1x glass reduction and 1x built-in height. It is suitable for PVC, Wood or Aluminium windows

MultiCoust EPC can be used in different ways:

  • Over the glass
  • Between two profiles, or
  • On the window, behind the wall cladding

The Aralco MultiCoust EPC System is easy to clean thanks to the removable inner profile which is also designed to keeps out insects

There is also the significant benefit of achieving 3 different airflows using only one standard glass reduction. The self-regulating valve functions automatically with changing airflows, allowing for constant ventilation and uniform airflow

Technical information, drawings and specifications are available upon request, or can be downloaded from www.aralco.be
