Description

Keep dust where it belongs, outside your caravan, with the Australian-made HTP 12 Volt Dust Reduction System. Designed to create positive air pressure inside your van, this system actively prevents dust from being drawn into the cabin, helping maintain a cleaner interior and a more comfortable travelling environment, especially on unsealed and outback roads. Built and tested in Australia, the HTP Dust Reduction System is engineered to handle harsh touring conditions. At its core is a powerful 80W Davies Craig fan delivering an impressive 696CFM of airflow, providing consistent cabin pressurisation even during extended off-road driving. A high-efficiency paper filter captures fine dust particles before they enter your living space, reducing interior cleaning and helping protect soft furnishings and electronics. Constructed from UV-resistant materials and weighing just 4.25kg, the unit offers a strong balance of durability and lightweight design. Installation is straightforward using standard roof hatch cut-outs, with optional spacers available for caravans with thicker roofs. Whether you’re tackling corrugated tracks or long dirt highways, this system delivers proven protection backed by Australian manufacturing and real-world testing. An essential upgrade for serious caravan travellers wanting cleaner air, reduced dust ingress, and greater comfort on every trip.

Why people choose the HTP Dust Reduction System

Driving on dusty roads can quickly fill a caravan with fine red dirt through small gaps and vents. The HTP Dust Reduction System helps reduce dust ingress by creating positive cabin pressure, forcing filtered air into the van and pushing dust out through gaps instead of letting it in.

Important note: Professional installation by a qualified auto electrician or caravan technician is recommended.

Built for Australian off-road conditions

The HTP Dust Reduction System is Australian made and developed specifically for harsh touring environments. It is designed to handle heat, vibration and long stretches of corrugated roads commonly encountered during remote travel.

Durable materials and a rugged design help ensure reliable operation across outback trips, off-grid touring and extended caravan adventures.

Creates positive cabin pressure to reduce dust

The system works by forcing filtered air into the caravan interior, creating positive pressure inside the cabin.

This pressure pushes air outward through small gaps and seals rather than allowing dusty air to be drawn inside, helping keep your caravan interior cleaner when travelling on dirt roads.

High airflow 12V fan performance

Powered by an 80W Davies Craig fan rated at 696CFM, the system delivers strong airflow while operating efficiently on 12V power.

This high airflow helps maintain positive pressure inside the cabin, ensuring filtered air circulation during dusty driving conditions.
