PASSIVE SECURITY VENTILATOR TECHNICAL SPECIFICATION
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.
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
The above size range is available ex stock with right hand control
(looking from inside the house) in black or white powdercoated finish.
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.
Special sizes are available on request. Delivery is within three working
days of receipt of the order. Prices are based on the nearest standard
size above; there is no extra charge for a special size. Standard
sizes can be recut to special requirements by the fabricator. Simply
follow the instructions supplied with the vent.
LONG LENGTH SYSTEM
5m lengths and associated components can be purchased subject to certain
conditions regarding quantity and training.
Initially only matt black and gloss white powdercoated finishes are
available ex stock. The colour range will be increased as the pattern
of customer requirement becomes established. Special anodised or powdercoated
colours are available on request. Price and delivery times are to
be established on application. Cord controls are available, but are
unnecessary where the knob can easily be reached.

"Easy Air" is a high specification vent designed for NZ conditions and
complies with NZ4211 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). Telarc test reports
are available on request by contacting the manufacturer. We strongly
recommend you read our "general information on background ventilation"
or contact BRANZ for one of their detailed reports appropriate to your
