Airrex Diesel Heater – AH300i

Airrex AH-300i

The Airrex AH-300i is a powerful diesel infrared heater designed for large workshops, agricultural buildings and commercial spaces up to 1500m³. Combining advanced burner technology with smart connectivity, it delivers clean, efficient and ultra-quiet heating.

Featuring a patented oil burner with electric fuel pump, combustion gases are circulated through ceramic-coated pipelines to produce comfortable infrared heat. The triple combustion process ensures complete and clean burning, while normal ventilation is sufficient.

An internal silencing system keeps operating noise to just 48 dB. With no fan, no dust and no smell, the AH-300i provides consistent radiant heat without air movement.

The heater includes Wi-Fi connectivity as standard, with optional 4G capability for full remote control via the Airrex mobile app. Users can monitor temperature, fuel levels and operating status in real time. The system automatically restarts after power outages, maintaining previous settings.

Finished in dark graphite grey, the AH-300i features a redesigned burner, reinforced protective grid, sealed fuel cap to prevent spillage, integrated wheels for mobility and a 3-year warranty.
