The GY20 is a compact, mushroom-type domed roof ventilator from Dometic for use in campervans, motorhomes, caravans, and boats. It provides effective ventilation using the differential pressure principal, so it is silent, has no moving parts, and requires no power source.

The exterior dome is robust and weatherproof, and features a built-in flyscreen. It is simple and straightforward to install, fitting into a 130mm diameter hole and suitable for roof thickness from 25-45mm.

This ventilator is ideal for use in smaller areas such as above kitchens or in bathrooms, or in locations where running power to a motorised fan is problematic.
