Neptune Oil Dehydrator Unit NDU-2NX: 25 L/MIN (1,500 L/HR)

The NDU-2NX is the larger brother to the entry level NDU-1NX unit, it has a double length filter housing and increased flow rate and water absorption capabilities per element.

With a flow rate of 25 L/min (1,500 L/hr) and the added capacity of a filtasorb2 double length element the NDU-2NX has the ability to remove both free and entrained water down to under 100ppm.

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 in ISO/NAS/SAE in a matter of minutes.
