The SmartVent Positive 3 is ideal for most homes including renovations. For newer properties passive air pathways should be included to effectively channel moist air out of the home.

Home ventilation systems are ideal for areas with environmental conditions that necessitate closed windows. This includes medium to high background noise areas, or regions with strong odours.

Suitable for:

• Homes of up to 560m²
• Standalone homes
• Terraced homes
• Low rise apartments
• Retirement homes
• Student accommodation
• Up to 3 storey dwellings (design dependent)
• All New Zealand climate zones, but ideal for warmer regions.
• Integrating with ducted or high-wall heat pumps
• Installation within roof cavities
• Easily expandable via the SmartVent design service

• Must be installed in accordance with the installation instructions and recommendations made by SmartVent.
• Not suitable for larger commercial properties.

The SmartVent Positive 3 is designed to comply with NZ Building code, although correct design and installation is required in order to meet these standards. 

The acceptable solutions for G4 (G4/AS1) outlines specific ventilation requirements in homes. If natural activities or environmental conditions produce any of the types of air pollution outlined in NZBC G4 3.3 , mechanical ventilation is required. 

Additionally; as per table 2 in NZS4303:1990, private dwellings require 0.35 air changes per hour, but no less than 7.5 L/s per person, if openable windows aren’t suitable.

System filters: All SmartVent systems are supplied with an F7 filter, which is capable of capturing up to 90% of 0.4 micron particles such as fine pollens, dusts and other allergens from the air. High quality HEPA filters are also available, which can capture particles 0.04 microns in size, an ideal solution for asthma and allergy sufferers. For environments with strong odours carbon filters can be fitted.

Comfort add-ons:

Flexi Air Source: Ideal for taking advantage of summer cooling, a flexi air source enables the Positive3 home ventilation system to bypass the heat recovery core, keeping incoming air cool.

Tempering Heater: SmartVent tempering heaters are inline heaters which gently warm air as it passes through the system. Not suitable as a replacement for heating within a home, a tempering heater will make the incoming air more comfortable. 

Heat Transfer: Ideal for transferring warmth from one hot room, like a lounge with a fireplace, to another cold room.

All SmartVent systems feature a 5 year warranty.
