Airrex is a market leader of fuel-powered infrared heaters . The AH-300 is an almost completely odourless diesel-fired infrared heater with 100% efficiency and can run on red diesel / normal diesel, fuel oil and  Neste MY biodiesel, which is made from food waste. Winter edition of the fuel should be used at temperatures below 10°C and also works without mains current by connecting a power bank (rechargeable Lithium battery power pack) should the dreaded power cut happen or areas without mains power such as outbuildings, workshops / marquee for example.

Product Description

Airrex AH-300 is the best-selling fuel-fired diesel heater – for a good reason.

There is no need to connect a separate exhaust to the Airrex AH-300 infrared heater when using the heater indoors, such as in a hall, garage or tent. This heater does not emit burning smells or visible smoke.

AH-300 heater can run on Neste MY biodiesel, which is made from food waste, and on normal diesel and fuel oil. Winter edition of the fuel should be used at temperatures below 10°C.

The Airrex AH-300 diesel heater is extremely inexpensive to use. On full power, the heater only uses a little over one litre of fuel per hour. If the heated space is a normally insulated hall of 500 m3, the outside temperature is +0 °C and the temperature inside is maintained at +15 °C, Airrex AH-300 will consume approximately 2.5–3 litres of fuel per day.

This infrared heater has no fan. The infrared radiation produced by the device heats materials, not air. The infrared heat is distributed evenly in all directions and feels pleasant even right next to the heater. The infrared heat produced by Airrex AH-300 spreads more evenly than heat produced by a fan-equipped heater, even in a large space.

Airrex AH-300 heater has 12 different safety systems, which makes it an extremely safe heater. The heat radiating from the heater is not scorching hot, and its surfaces are not scalding.

The heater is very easy to take into use because fixed installation is not required. The heater is on castor wheels, which makes it easy to move where you want it. Airrex AH-300 is extremely quiet at only 48 dB.

Airrex AH-300 is the best heating option for the efficient and pleasant heating of many kinds of spaces. The heater is ideal for industrial halls, working areas, machinery shelters, stables, halls, breakrooms, maintenance vehicles, public events, repair shops, terraces, tents and construction sites, for example.

Airrex AH-300 heater has a 1-year factory warranty. We keep all the parts in stock, so spare parts deliveries are possible in just a few days.




Technical introduction

The device has an oil burner equipped with an electric fuel pump, which recycles the exhaust through pipes with ceramic coatings, giving out the heat as infrared radiation.

The triple combustion process guarantees completely pure combustion; the heater does not need a separate exhaust pipe, which conserves all heat for utilisation. Normal ventilation is sufficient.

Odourless burner

Normally, the fuel that enters the combustion chamber of heaters after they are switched off generates soot and unpleasant odours. According to laboratory tests, the fuel injection of Airrex heaters cuts off very quickly, minimising the formation of soot and odours.

An exhaust pipe that saves energy and eliminates odours

A metal honeycomb installed inside the combustion chamber burns residual gases and ensures efficient and steady combustion. The 75/100/165-millimetre alternating diameter of the tubular combustion chamber makes the combustion more efficient and minimises the amount of non-combusted gases. The rubber tube for inlet air ensures the supply of fresh air to the burner, which also improves the efficiency of combustion.

Extremely effective noise reduction

The noise reduction system in the exhaust pipe, which compresses and expands the exhaust gases, makes Airrex extremely quiet (only 48 dB).

Airrex is an extremely safe heater with 12 safety systems:

• Ignition safety system

• Flame guard

• Fall sensor that switches off the heater

• Overheating prevention

• Safety system that recognises power outages

• Fuse

• Burner protection

• Fuel level monitor

• Temperature sensor fault detector

• Motor start helper

• Device lock

• Programmable switch-off (user can program)
