About the Airtac GPF Oil Mist Separator GPF400N10AJD
In the AirTAC GPF400 ordering code, the trailing D of GPF400N10AJD selects the finest element in the range: a 0.01 um coalescing cartridge with 99.9% efficiency that strips oil mist and ultrafine particles from compressed air. Because the tight element passes less air than the M grade, rated flow is 600 L/min (inlet 0.7 MPa, outlet 0.5 MPa), so match it against your actual air consumption before committing to this code.
The rest of the code fixes the build: 3/8 in (10) PT-threaded ports, an N-coded nylon bowl holding 89 cc of condensate, and an A-coded automatic drain that ejects collected water without anyone opening the manual petcock. The J suffix means no mounting bracket is supplied, so plan your own fixing or a panel adapter. Operating envelope is 0.15 to 1.0 MPa (20 to 145 psi), proof pressure 1.5 MPa (215 psi), and -5 to +70 C with no freezing.

How to choose
Pick GPF400N10AJD when the task demands sub-micron air purity on a 3/8 in line and you can handle your own mounting. Against sibling GPF400N10AJM you gain the 0.01 um element but give up flow (600 vs 1100 L/min); against bracketed builds without the J suffix you lose the included bracket. If your line is 1/2 in, step up to the 15 port option, and swap PT for G or NPT thread via the G or T codes.
Applications
Lab and test-rig air polishing
A 0.01 um element at 99.9% efficiency removes oil mist ahead of instruments and analyzers where even trace oil skews readings, with the automatic drain keeping the 89 cc nylon bowl clear between service rounds.
Protecting precision pneumatic sensors
Feeding position sensors, electronic proportional valves and fine control circuits through this separator prevents oil film buildup that degrades response, on a compact 3/8 in PT supply branch.
Coating, printing and marking heads
Spray and ink-jet heads clog quickly on oil-carrying air; the D-grade element polishes the supply, while the auto drain suits equipment that runs unattended between operator checks.
FAQ
What are the key figures for GPF400N10AJD?
3/8 in (10) PT ports; nylon bowl (N) with 89 cc capacity; automatic drain (A); 0.01 um element (D) at 99.9% efficiency; rated flow 600 L/min at 0.7 MPa inlet and 0.5 MPa outlet; operating pressure 0.15 to 1.0 MPa (20 to 145 psi); proof pressure 1.5 MPa (215 psi); temperature -5 to +70 C, no freezing; no bracket (J code).
How does the automatic drain on this model behave compared with the standard drain?
The standard GPF400 drain is differential-actuated plus manual; the A code in GPF400N10AJD replaces it with an automatic drain, so condensate gathered in the 89 cc nylon bowl discharges on its own instead of waiting for a manual purge. That removes the risk of a waterlogged bowl pushing oil mist downstream, which matters most with the fine 0.01 um element this code carries.
