The EasyAir vent is manufactured from extruded aluminium with PVC slide and exterior grade Nylon end caps.

Cord controls are available, but are unnecessary where the knob can be easily reached.

Recommended Airflow

Following extensive research in the UK a minimum requirement for background passive ventilation (also known as trickle ventilation) has been adopted. This minimum requirement is for 4000mm2 minimum air opening per average sized room that is used for normal living activities. This does not include bathrooms, laundries or kitchens. These may require more ventilation in the absence of other methods of moisture extraction.

The minimum air opening is proportional to the overall length of the vent x 8000mm2 per metre less an allowance of 740mm2 for end caps.

Example: Vent overall length 600mm = 0.6 x 8000 = 4800 – 740 = 4060mm2

Standards and Testing

EasyAir is a high specification vent designed for NZ conditions and complies with NZS 4211 Standard for windows (1985). Its air leakage factor complies with level 2 of the above standard so it can therefore be used commercially in air conditioned buildings. It can be cut to any size within the constraints of appearance (too small) and wind loading (too long).
