O2VENT Positive Pressure Fresh Air Ventilation System

Opening a window lets you enjoy fresh air in your home, but it’s not always practical, especially during the hotter or colder months of the year. Plus it allows pollen and other pollutant particles into your home and leaving your windows open while away at work for the day can be a major security issue. Many people experience stuffy, foul-smelling air when arriving home after a hard day’s work, not to mention after a holiday.

A whole house positive controlled fresh air supply system distributes filtrated fresh air into every room by an adjustable speed reliable fan, flexible ducts and air outlet diffusers. While polluted moist, stale indoor air will be pushed out.

The constant supply of fresher and purer air will maintain a healthier indoor environment for you and your family.

Filtered Outdoor Fresher Air, Easier breathing at home

Before delivering fresh outdoor air to indoor rooms by Inline Duct Fan, the air filter installed in the ventilation system captures pollutants such as ozone, greenhouse gasses, chemicals, pesticides, pollen, mould spores and radon to keep a comfortable, healthy indoor environment.

The air filter is the vital part of the mechanical ventilation system in your home, replacing your air filter regularly keeps your ventilation system working with peak efficiency, while maintaining a healthy indoor environment for your family. Filters are usually changed once a year or more frequently, if necessary, depending on filtration demand.

Please contact our service team to request a replacement service or simply purchase a filter from us for DIY replacement.

Reducing Condensation and Mold

By introducing pure filtered fresh air into a home, the positive pressure fresh air flow will then push stale, moist, polluted indoor air out of the house. The activities of indoor occupants will produce extra moisture. Activities such as cooking, showering, use of clothes dryer, use of a fireplace and even the breathing of humans and pets inside. For those poorly insulated houses, the temperature on the surface of the wall, ceiling, windows and doors are lower than the dew point in Winter. Warm and humid indoor air contains a large amount of water vapour, it will cause condensation on the cool indoor surfaces, thus mould and malodour will appear rapidly. This is harmful to family health and house structure, this a Fresh air ventilation system is the most effective strategy for improving indoor air quality.
