Technical Specifications
This ventilator is easy to fit and comes complete with insect
screen and weathering canopy. The Easy Air
vent provides cost effective controllable "glazed in ventilation"
with total security suitable for both single and double glazed
applications. It's suitable for use with aluminium, UPVC and
timber joinery.
The Easy Air 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 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

Vents exceeding 1100mm in length may require a stiffener
if exposed to high wind loadings depending on the depth of the
glass pane below the vent. Check when placing your order.

for NZ conditions and complies with NZ 421 1 Standard for
windows. 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).
