Neptune Oil Dehydrator Unit NDU-3NX: 50 L/MIN (3,000 L/HR)

Neptune Oil Dehydrator Unit NDU-3NX: 50 L/MIN (3,000 L/HR)

The NDU-3NX is the third Neptune in the family of Filtertechnik's Neptune Dehydrator units offering double the capacity of the NDU-2NX model and the ability to work continuously.

With a greater flow rate of 50 L/min (3000 L/hr) and the added performance of filtasorb2 ability to remove water down to 100ppm or better the NDU-3NX is suited for larger cleanup applications that require higher flow rates such as larger marine or hydraulic systems.

Should on-site verification of cleanliness and water content levels be required, practical quick connect fittings allow for instant plug-in to the Particle Pal, allowing real time results of ISO/NAS/SAE cleanliness codes and water content expressed as ppm or %RH.

Filtertechnik’s NDU-NX range is the perfect solution to quickly and cost effectively remove both free & entrained water in a variety of oils.
