Passive Ventilation

When minimum energy consumption, easy maintenance and silence are top of your priority list, a Passive Ventilation System is a natural choice. Passive ventilation uses the natural forces of wind and the stack effect by which air rises in order to renew air supply within the home. Moist and stale air is extracted directly through ducting up to a roof termination and then vented outside. The air inside a property is normally warmer than that of the outside air so rises naturally up the ducting, carrying the moistened content with it. Replacement fresh air flow is provided to the entire home by placing inlets in dry rooms (living and bedrooms).

Passive ventilation used with humidity controlled background inlets and outlets delivers optimal ventilation on a room by room basis throughout the dwelling. Humidity controlled sensitive grills open as much or as little as required depending on the humidity levels within each room, providing an energy efficient and cost effective ventilation system.

Mechanical Extract Ventilation

Mechanical Extract Ventilation provides continuous extraction of stale, damp air from all wet rooms such as kitchens, bathrooms and utility rooms. The system costs less to supply and install than individual separate fans and helps to reduce the amount of background ventilators required. MEVs are suitable for a wide range of buildings from individual apartments and houses to student accommodation units and nursing homes, and can be designed to ventilate either an individual house or several apartments simultaneously. MEVs require minimum installation and provide maximum retention of valuable warm air in wintertime. Options include demand control mechanical extract which operates with humidity controlled grills.
