Brunner Camping Accessories

Brunner's camping accessories collection covers the practical items that keep a caravan, motorhome or campervan running smoothly on site. This range includes the Monsun 12V fan for in-vehicle ventilation, the Ruckstep ALU and Rialto folding caravan steps, the Aquafil and Roll On 2.0 hose reel systems for fresh water supply, the Plitter and Pillar Foldaway waste bins, and the Polarys Twinair NG and Polarys Imperator portable split air conditioning units. These are the support products that sit alongside Brunner's furniture, awnings and kitchen ranges.

What camping accessories does Brunner offer for caravans and motorhomes?


Brunner's accessory range covers ventilation (Monsun 12V fan), vehicle access (Ruckstep ALU double step and Rialto single step), water supply (Aquafil, Aquafil Pro and Roll On 2.0 hose reels), waste management (Plitter and Pillar Foldaway 8L bins) and climate control (Polarys Twinair NG split air conditioner and Polarys Imperator). Each product addresses a specific on-site need.

The Ruckstep ALU is a folding double-step built from aluminium, weighing 4 kg and measuring 51.5 x 53 x 38.5 cm when open. Anti-slip treads on both steps provide secure footing in wet conditions. It folds flat for storage in a caravan locker or motorhome garage. The Rialto is a single-step alternative in a lighter, more compact package for vehicles where the door threshold is lower. Both steps are designed for daily entry and exit from touring vehicles. For water supply, the Aquafil is a basic hose reel, the Aquafil Pro offers a larger capacity and improved winding mechanism, and the Roll On 2.0 provides a wall-mountable or freestanding option. All three use standard hose fittings compatible with UK campsite taps.

The Polarys Twinair NG is a portable split air conditioning unit with both heating and cooling functions. It comprises an external condenser and internal evaporator connected by flexible hoses that pass through a window opening. The NG model delivers 3,000 BTU cooling and also provides hot air output, runs on 230V mains power and operates at 53 dB. It cools rooms up to 25 to 30 cubic metres with a temperature range of 16 to 30 degrees Celsius, controllable via a smartphone app. The Polarys Imperator is a more compact unit for smaller spaces. The Monsun 12V fan provides direct ventilation and runs from a vehicle's 12V supply, making it useful during off-hookup stops. The Plitter bin and the Pillar Foldaway 8L are compact waste bins designed for the confined spaces inside a campervan or under an awning, folding flat when not in use.

When choosing accessories, prioritise based on your touring style. If you camp primarily on hookup pitches in warm weather, the Polarys Twinair NG transforms comfort levels, particularly for sleeping on hot summer nights. The double-step Ruckstep ALU suits motorhomes and caravans with higher door thresholds, while the single Rialto works for lower-entry campervans and smaller caravans. For water management, the Aquafil suits occasional campers, while the Aquafil Pro and Roll On 2.0 are better for frequent tourers who want a neater, more durable setup. Entry-level accessories like the Rialto step and Plitter bin are budget-friendly essentials. Mid-range items include the Ruckstep ALU and Aquafil Pro. The Polarys air conditioning units sit at the premium end.

The most common accessory mistake is buying a step that's the wrong height for your vehicle. Measure from the ground to your door threshold before choosing between the single Rialto and double Ruckstep ALU. For air conditioning, remember that the Polarys Twinair requires a 230V mains hookup and draws power from the campsite supply, so it is not suitable for off-grid use. The unit needs a partially open window or purpose-cut panel for the hose connection between the indoor and outdoor units. Hose reels should be fully unwound during use to prevent kinking and pressure loss. Store the Polarys units in their carry cases between trips, and run the fan-only mode for 30 minutes before packing away to dry the internal components and prevent mould.

Frequently Asked Questions


Does the Brunner Polarys Twinair work off-grid?
No. The Polarys Twinair NG requires a 230V mains electricity supply and draws approximately 560W. It is designed for use on campsite hookups. It will not run from a 12V leisure battery or standard portable power station. For off-grid ventilation, the Brunner Monsun 12V fan operates directly from your vehicle's 12V supply.
What is the difference between the Ruckstep ALU and Rialto step?
The Ruckstep ALU is a folding double-step made from aluminium, weighing 4 kg and measuring 51.5 x 53 x 38.5 cm when open. It suits motorhomes and caravans with higher door thresholds. The Rialto is a single-step option that is lighter and more compact, designed for vehicles with lower entry points like campervans and smaller caravans. Both have anti-slip treads and fold flat for storage.
How loud is the Brunner Polarys Twinair air conditioner?
The Polarys Twinair NG operates at 53 dB, which is roughly equivalent to a quiet conversation or a household fan. It includes a night mode that reduces noise further for sleeping. The split design means the noisier condenser unit sits outside the vehicle, while the quieter evaporator unit sits inside.
Can the Polarys Twinair NG also heat?
Yes. The Twinair NG model (Hot and Cold) provides both cooling and heating functions. It has a temperature range of 16 to 30 degrees Celsius and can be controlled via a dedicated smartphone app. This makes it useful for spring and autumn touring when temperatures drop at night but a full heating system is not required.
How do the Brunner hose reels connect to campsite taps?
The Aquafil, Aquafil Pro and Roll On 2.0 use standard hose fittings compatible with UK and European campsite water points. The Roll On 2.0 features an improved reel mechanism for tangle-free winding. Always fully unwind the hose before use to prevent kinking, and drain and dry the hose before storage to prevent bacterial growth and freezing damage in colder months.
