The NPS-A4 is the smallest and lightest flight-certified potable water treatment unit in the sky today. Measuring only 12.5” x 6.25” x 4”, and weighing just 5.6 lbs, the NPS-A4 supplies clean, disinfected water at the rate of 1 US Gallon per minute.

Developed from IWG's patented NPS-A3 aircraft water treatment unit, the NPS-A4 is reduced in size and weight by retaining only the ultraviolet treatment chamber. The same high level of ultraviolet disinfection is achieved, along with increased installation flexibility.

The NPS-A4 also retains advanced monitoring capabilities, which allow flight crew to test the unit pre-flight and then monitor its status via either the panel on the unit or an auxiliary indicator panel mounted in the cockpit or cabin.

Dassault Falcon Jet offers the NPS-A4 as an option on its new 900 and 2000 series aircraft. IWG also holds an STC for NPS-A4 installations on existing 900 series aircraft, making retrofits much simpler for operators interested in the highest quality onboard water for passengers and crew.

IWG is also offering a version of this product to the commercial aviation industry, where its small size makes it especially suited for galley installations.

Optimized to fit small spaces, the NPS-A4 is also an attractive water treatment option for operators of any aircraft type with an active water system.
