## Product description

### Roof ventilator for caravan, motorhome and boat

The Dometic GY 20 is a compact roof ventilator for fixed installation in a caravan, motorhome or boat. This model provides natural ventilation without an electric motor, giving you fresh air and air extraction without additional power consumption.

Thanks to its operation based on pressure difference, the GY 20 ventilates silently. That makes it interesting for anyone looking for a simple and quiet solution to improve air circulation in a vehicle or small cabin.

### Silent ventilation without a motor

This roof ventilator has no moving parts and does not require a power supply. As a result, it is not only quiet in use, but also practical for applications where simplicity and limited installation requirements are important.

The plastic roof dome is designed to be watertight and offers solid protection against weather influences. This makes the ventilator suitable for use on the roof of recreational vehicles and boats where ventilation and weather resistance need to go hand in hand.

### Compact and practical in use

With dimensions of 200 x 64 mm, the Dometic GY 20 remains a compact solution for roof ventilation. The net weight of approximately 0.4 kg helps keep the extra weight on the roof to a minimum.

Key features at a glance:

- roof ventilator with plastic roof dome
- works without a motor or fan
- no power connection required
- silent operation via pressure difference
- compact dimensions of 200 x 64 mm

### Suitable for exterior and ventilation upgrades

For renovation, replacement or a practical ventilation upgrade to the exterior, this is a functional choice focused on quiet operation and a compact installation size.
