Healthy Home Ventilation

Smooth-Air is committed to introducing new and innovative products that are designed to optimise the indoor air quality and lower energy consumption. These products are helping to improve comfort levels, and create healthier more productive internal spaces by introducing fresh filtered air into the environment.

Why the need to ventilate your home?

These days as we try to be more energy conscious, we build for ourselves lighter, better insulated and sometimes quite unbreathable homes.

Normal family life generates considerable moisture from such activities as cooking: 3 litres per day, showers, and baths: 1.5 litres per day, body respiration and perspiration 1-2 litres per day per person etc. (BRANZ). With this level of moisture generation combined with current tight home construction, relative humidity levels (airborne moisture) increase dramatically. This causes problem condensation and produces a home that ultimately becomes harder to heat and makes insulation less effective.

Positive vs Balanced Pressure Ventilation

Traditional domestic ventilation systems are ‘positive pressure’. They bring air in from outside via the roof space and force the stale air out through gaps around windows and doors. The incoming air from these systems must be heated or cooled to keep the house warm in winter or cool in summer.

Whereas ‘balanced pressure’ systems extract air from the house while simultaneously bringing fresh air in. These two streams of air pass through a heat exchanger, which warms incoming air in winter and cools incoming air in summer. This heat exchange process means that up to 80% of the energy, which would be wasted using a traditional positive pressure system, is recovered, resulting in significant energy savings, and therefore cost savings.

Positive Presure

To provide a cost effective solution to condensation problems Smooth-Air have designed, developed and manufactured the Dry- Matic range in New Zealand for New Zealand conditions.

Balanced pressure

The HEX390 is a ‘balanced pressure’ system. It extracts air from the house and at the same time brings fresh air in. These two streams of air pass through a heat exchanger, which warms incoming air in winter and cools incoming air in summer.
