AUX J-Smart ASW-H18E3E4/JOR3DI-C0 – 18,000 BTU Inverter Air Conditioner
The AUX J-Smart is a wall-mounted inverter split air conditioner for medium-sized rooms up to approximately 37 m². With 18,000 BTU (5.3 kW nominal) cooling capacity, integrated Wi-Fi, plasma air-purification filter and self-cleaning function, it combines comfort and intelligent control at a competitive price point. The R-32 refrigerant is environmentally optimised, and the unit operates reliably down to outdoor temperatures of -25 °C in heating mode.
Features & Highlights
Plasma Filter
The AUX J-Smart ASW-H18E3E4/JOR3DI-C0 inverter air conditioner ensures perfect climate and air quality in your home or office thanks to its built-in plasma filter. The cold plasma eliminates dust, removes odours and smoke, providing cleaner air and a healthier indoor environment.

Self-Cleaning Function
AUX J-Smart air conditioners feature a self-cleaning function. It generates a large temperature difference in a short time — first running in cooling mode so that condensation removes accumulated dust and bacteria, then switching to heating mode, and finally activating only the fan to fully remove moisture from the inside of the unit. This prevents the development of bacteria and mould and achieves up to 90 % sterilisation.

Wi-Fi Control
For greater convenience, AUX J-Smart series air conditioners can be controlled remotely using the included Wi-Fi controller. Simply follow the instructions to activate it and use it from your smartphone.

Reliable Operation Down to -25 °C
The additional heating system on the outdoor unit of J-Smart air conditioners gives you the certainty that on colder winter nights your home will keep being heated reliably — even at outdoor temperatures down to -25 °C.

Frequently Asked Questions
How do I choose the right BTU size for my room?
The key figure is the manufacturer’s recommended room size for this unit — you will find it in the product’s technical data. For sun-facing or top-floor rooms, we recommend the next larger capacity class. Our team is happy to advise.
Do I need a certified technician for installation?
Yes — split air conditioners with fluorinated refrigerant must be installed by a certified F-Gas technician (EU Regulation 517/2014). Self-installation is not permitted. We can arrange a qualified installer in your region.
What warranty is included?
Standard manufacturer warranty is 36 months on the unit, provided installation is carried out by a certified F-Gas technician. Detailed warranty conditions are in the product datasheet.
What do SEER and SCOP mean?
SEER (Seasonal Energy Efficiency Ratio) is the seasonal cooling efficiency — higher is better. SCOP (Seasonal Coefficient of Performance) is the seasonal heating efficiency. SEER ≥ 6.0 and SCOP ≥ 4.0 are considered very good for residential split air conditioners.
