The Dometic FreshJet FJZ4 2200 is the highest-output model in the FJZ4 fixed-speed range, delivering 2200W of cooling and 1000W of heating for caravans, motorhomes, and campervans up to 7 metres in length. It features electronic controls, Wi-Fi connectivity, integrated CleanAir air purification, and a soft-start function that shortens the compressor start-up phase to prevent breaker trips on campsites with unstable or lower-rated power supplies. Available in white or black (the black finish applies to the rooftop unit only), it weighs 29.8 kg and shares the same compact 752 x 225 x 702 mm dimensions as the smaller FJZ4 models. It draws 4.6A for both cooling and heating modes, requiring a minimum circuit protection of 5A.
Which motorhome air conditioner is best for vehicles up to 7 metres?
The Dometic FJZ4 2200 provides 2200W cooling and 1000W heating through a fixed-speed compressor, making it the top-performing unit in the FJZ4 series. Its built-in soft-start function and 5A circuit protection requirement means it handles campsite hook-ups reliably. At 29.8 kg and 752 x 225 x 702 mm, it fits a standard 400 x 400 mm roof opening.
Like the FJZ4 1700, this model connects to the Dometic smartphone app via built-in Wi-Fi for remote temperature monitoring and control. The CleanAir bipolar ioniser system comes fitted as standard, actively reducing bacteria, odours, and mould. The compatible air distribution box is the FJZ ADBD (sold separately), which includes an electronic touch control display, warm white LED ambient lighting, adjustable outlet vents, and a reusable dust filter. Air is distributed front and back at a rate of 350 m³/h. The unit uses R32 refrigerant (360g charge, GWP 675) and operates across an ambient temperature range of -2°C to +52°C. It fits roof thicknesses between 25 mm and 60 mm through a standard 400 x 400 mm roof cut-out.
The soft-start function on the FJZ4 2200 sets it apart from the 1500 and 1700 models. During the compressor start-up phase, which generates the highest current spike, the soft-start system provides additional support so the start-up completes before the fuse has time to trip. This also helps tolerate voltage drops caused by overly long supply cables or cable drums at campsites. For owners of longer vehicles who want dual-zone climate control, the FJZ4 2200 pairs well with the smaller FJZ4 1500 as a second unit, with the 1500's low starting current making it particularly reliable alongside the 2200's soft-start system. Dometic provides a 5-year warranty on parts.

Frequently Asked Questions
The soft-start function on the Dometic FJZ4 2200 provides additional support to the compressor during its start-up phase, when current demand is at its highest. This shortens the start-up period so it completes before the campsite fuse has time to trip. It also helps the unit tolerate voltage drops caused by long extension cables or cable drums at campsites.
Both models deliver 2200W of cooling capacity, but they use different compressor technologies. The FJZ4 2200 has a fixed-speed compressor with soft-start and 1000W heating. The FJZ7 2200 uses an inverter compressor that varies its speed to match cooling demand, delivering 2000W of heating, quieter operation, lower energy consumption, Adaptive Power Mode, SmartECO off-grid function, and Advanced Sleep Mode. The FJZ7 2200 is the premium choice for the same vehicle size range.
The FJZ4 2200 draws 4.6A in both cooling and heating modes, with a minimum circuit protection of 5A. The soft-start function helps manage the initial start-up current spike, so it operates reliably on most campsite hook-ups. It runs on 220-240V AC at 50Hz.
Yes. Dometic recommends pairing the FJZ4 2200 (with its soft-start function) alongside a FJZ4 1500 (with its low starting current) for dual-zone setups. This combination allows you to control bedroom and living areas independently, and the low power demands of both units mean at least one will always operate comfortably, even on campsites with limited circuit protection.
Yes. All electronic FJZ4 models (1700 and 2200) and all FJZ7 models include the Dometic CleanAir bipolar ioniser system as standard. This technology creates positive and negative ions to reduce bacteria, odours, and mould inside the vehicle. The reusable dust filter in the air distribution box provides additional particle filtration.
3 years warranty when fitted at the Dometic Fitting Centre
We have partnered with Dometic to offer you an
extra years warranty. If you buy the fitted option above you will take your vehicle to the Dometic Fitting Centre in Tewsbury. The price paid here includes the
standard fitting and it will be fitted directly by Dometic themselves. As Dometic are fitting the air conditioning unit, they are happy to offer 3 years warranty instead of 2! You will also have the piece of mind that the fitting of the unit will be first-class as it will be fitted by a dedicated team of Dometic Service Engineers.
What happens once I place the fitted order with us?Once you place the order with us, we will send your details to the Dometic Fitting Centre. A Dometic team member will then contact you to organise a convenient time for you to bring in your vehicle. Be advised that Dometic will require a photograph of the roof of your vehicle as well as an interior image of the roof light and the surrounding area so they are able to assess if any additional work will be required to fit the unit. We will request this by email after you place the order with us. Please ignore the shipping information. We will not ship the FJX41500 to you, it will be delivered to the fitting centre in Tewkesbury awaiting your vehicle.
Standard fitting involves the removal of an existing 400 by 400 roof light and replacing with, and wiring in, the roof-top unit and installation of the ADB inside the interior of the vehicle. The cost does not include the moving or any other rooftop items you might have e.g. solar panels. If it is found that additional work is required the Dometic Fitting Centre will advise accordingly.
