The build up of dust and dirt on the vent with fly wire is even.
There is no minimum mesh size in the standard.
Similar calisthenics would be required when inspecting
vents to ensure they are clean would physically tax some
owners and operators.
Even if a caravan has a vented range hood/extractor
no lower than 400mm from the ceiling, a floor vent is still
required to provide free flowing air throughout the caravan
or any compartments that can be temporarily isolated by a
door or curtain.
Caravans could be subjected to days or weeks of travel in
Australian conditions, and fixed-mesh vents would become
clogged and ineffective.
The reason given for fitting mesh over a vent is to keep out
insects like mosquitoes that may be harmful to humans. Yet
caravan enthusiasts like to sit outside and enjoy a camp fire
or the star-filled sky – just where insects can get to them.
Natural ventilation in a residence, caravan or a boat
relies on free flowing air through a minimum of two vents,
preferably one upper and the other lower as described in the
Standard.
Should one of these vents become even partly blocked, then
the natural ventilation required for the safety and efficiency of
gas appliances will cease or at least be diminished.
