Description

The HTP Dust Reduction System is an Australian-made positive pressure system designed to help reduce the amount of dust entering caravans, RVs and camper trailers when travelling on unsealed roads. By continuously introducing filtered air into the cabin, it creates positive air pressure that helps minimise dust entering through small gaps, improving comfort and reducing the amount of cleaning required after every trip. At the heart of the system is a powerful 12V 80W fan delivering up to 696CFM of airflow, combined with a high-efficiency paper filter that captures fine dust particles before they enter your living space. Built using durable UV-resistant materials, the rooftop unit is engineered to withstand harsh Australian conditions while remaining lightweight and easy to install using standard roof hatch cut-outs. An optional roof spacer is also available for installations requiring additional clearance. Proudly designed and manufactured in Australia, the HTP Dust Reduction System has been developed specifically for demanding touring conditions and proven across countless kilometres of off-road travel. Whether you're exploring remote outback tracks or regularly travelling on gravel roads, it provides an effective solution for maintaining a cleaner, more comfortable caravan interior throughout your journey.

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.
