Do Not:
• Have only one vent to remove hot air, as this does not work. You need air in and air out,
cross flow ventilation is the only way air will move.
• This also applies to fans. A sealed compartment with one opening with a fan in it does
not remove the air, again you need cross flow, air in and air out.
• Have dierent size vents, as this limits you to the smallest vent.
• Have dierent size fans for drawing air in and exhausting air out, will limit you to the
smallest fan. The rule applies when fitting a fan, if your fan is 120mm then as a minimum
your supply opening needs to be the same if not bigger.
• If you are using a supply and extraction fan they have to be the same in their
specifications, or you can end up with the air cavitating and not moving at all.
With the introduction of ‘dust free’ caravans and campers, there are a range of issues that
may impact the performance and air ventilation to your fridge due to dust reduction filters
and extraction fans. It is necessary to use hatches and vents to remove the hot air whilst
replacing it with fresh cool air (as seen in the diagram below). This will ensure your fridge
will be running at its peak eiciency and guarantee you’ll get a long life from your fridge.
• We recommend 2 vents - 480x250mm.
• One located level with the refrigerator motor.
• Second at the highest point of the fridge
cavity, to ensure all hot air escapes.
