The fridge ventilator greatly improves the circulation of the air flow around the fridge and aids the air flow across the condenser, regulating termperatures and maximizing the overall cooling performance of your fridge.
A Thetford vent gives a nice finish to the ventilation opening on the outside of your vehicle (the ventilation opening is needed for correct fridge operation).
A nicely designed cover thet can be placed over the ventilation grill during winter storage, while cleaning or when the temperature is below 8 degrees.
