Keeping Dust Out of Your Caravan: Tips and Solutions


Welcome back to another episode of Adventure Ready with Adelaide RV! Today, we’re diving into the world of dust prevention for caravans. As more people take their caravans off-road to explore Australia’s great outdoors, keeping dust out of your caravan becomes increasingly important. Let’s explore some effective dust prevention solutions, their costs, and how they work.


Traditional Scupper Vents


For many years, the scupper vent or pressure hatch was the standard solution for keeping dust out of caravans. These vents work by creating positive pressure inside the caravan, pushing clean air in and preventing dust from entering. They operate effectively when travelling at a minimum speed of 40-50 km/h, allowing the clean air to pressurize the caravan interior, thus blocking dust from infiltrating through vents and other openings. However, scupper vents have limitations:


– Cost: Approximately $300.

– Effective Speed: Minimum speeds of 40-50 km/h.

– Challenges: Difficult to open and close, risk of injury, and limited to lower speeds.


Dust Reduction System for your caravan - Scupper Vent


Dometic Dust Reduction System


Dometic has introduced a modern solution that looks similar to an air conditioner on your caravan’s roof. This system offers larger openings for increased airflow and includes a dust holder with a filter. The design leverages wind power while driving, with magnets holding the vent open, allowing clean air to flow through a large filter that traps dust particles.


– Cost: Approximately $800.

– Benefits: Larger openings for better airflow, effective filtering of dust.

– Drawbacks: Potential for water ingress during horizontal rain and care needed when emptying the filter to avoid spills.



HTP 12 Volt Pressure Hatch


For a more advanced solution, consider the HTP 12 Volt Pressure Hatch from ARL. This system uses a 12-volt battery to create a powerful air pressure inside your caravan, preventing dust from entering. It features a large black dome on the roof with a substantial paper filter underneath, which needs to be changed less frequently than smaller filters.


– Cost: Between $1,300 and $1,700.

– Benefits: High airflow, large filter needing less frequent replacement, no water ingress.

– Demonstration: Strong airflow visible when placing paper near door vents, showing effective dust prevention.



Carafan: The Ultimate Dust Reduction System


If you’re looking for the best dust prevention system, the Carafan is the top choice. This robust, metal-constructed unit fits into a skylight-sized opening and provides exceptional dust prevention. It operates with a simple switch to turn it on and off, and its powerful fan ensures that dust is kept out even in the harshest conditions.


– Cost: Between $2,200 and $2,500.

– Benefits: Near-zero dust ingress, ideal for any dirt road or bulldust conditions.

– Recommendation: Worth every cent for its effectiveness in keeping your caravan dust-free.





Understanding your options for dust prevention is crucial for safe and enjoyable travels. Whether you choose the traditional scupper vent, the modern Dometic system, the advanced HTP pressure hatch, or the ultimate Carafan, Adelaide RV has you covered. Each system offers unique benefits and is designed to keep your caravan clean and dust-free on your next adventure.
