Kingdom Power has been manufacturing, installing and maintaining vacuum toilets in the Railway Industry since 2012. AirFLUSH is the 3rd Generation vacuum toilet which has been developed from our Research and Development test bench. AirFLUSH is installed in Vans with a single toilet, Premium and Sleeper coaches having two toilets and Seater coaches having four toilets. AirFLUSH works on the principle of Vacuum on Demand, VoD making it highly reliable even when there are leaks on the waste pipeline. Each flushing cycle uses approximately 0,5 litres of water and 100 litres of air. The amount of water can be adjusted from zero to one litre depending on user requirements. Over 500 long-distance trains are equipped with our vacuum toilets ensuring passenger comfort and safety.
