SPEEDAIRE Zero Loss Drain
The SPEEDAIRE NLD-0050 is a pilot-operated zero-loss condensate drain designed for compressed-air systems. It removes accumulated moisture without venting valuable compressed air, helping maintain system efficiency. The unit features two 1/2 inch female NPT air inlets and a matching drain port, housed in an aluminium body. It suits industrial and automotive workshops that need reliable condensate management.
Installation and common issues
The drain connects via standard 1/2 inch NPT threads, so it fits directly into existing piping without special adapters. It operates on a wide 90 to 260 V AC supply, simplifying electrical hookup across different facility voltages. A frequent issue is installing the unit where system pressure falls below the 11.5 psi minimum, which prevents the pilot valve from actuating. Debris in the air stream can also foul the internal mechanism, so a pre-filter is advisable.
Who this suits and who should look elsewhere
This drain suits plants running pressures between 11.5 and 230 psi with ambient temperatures from 36 to 180 degrees Fahrenheit. It fits systems that can provide a 1/2 inch NPT connection and AC power within the stated voltage range. Buyers needing higher pressure ratings, larger port sizes, or DC voltage operation should look elsewhere. Facilities requiring a drain for sub-freezing environments will also need a different solution.

Questions about this item
How can I confirm the SPEEDAIRE NLD-0050 zero-loss drain is operating correctly after installation?
Verify that condensate discharges from the 1/2 in NPT drain port only when liquid accumulates and that no compressed air escapes during the cycle.
What components are included with the SPEEDAIRE NLD-0050 and what must be purchased separately?
The unit ships with an aluminum body, dual 1/2 in NPT female air inlets, a 1/2 in NPT female drain port, and internal pilot operation for 90 to 260 V AC. Piping, fittings, and a power cord are not included.
Which voltage version of the SPEEDAIRE NLD-0050 should I select for my supply?
A single version accepts 90 to 260 V AC, so the same unit works on common single-phase supplies without a separate model choice.
