Genuine AirTAC mist separator, order code GPF400C10D from the GPF400 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The GPF400C10D is the fine-filtration build of the AirTAC GP400 mist separator: its D option fits a 0.01 um coalescing element with 99.9% efficiency, catching the sub-micron oil mist and particles that a standard 0.3 um element lets through. It connects via 3/8 in PT ports, and because the finer element restricts flow, the rated flow is 600 L/min at 0.7 MPa inlet and 0.5 MPa outlet.
The C code gives a metal bowl of 89 cc, and with no drain letter in the code the drain is the differential-plus-manual type, so the unit needs periodic manual draining rather than an automatic drain valve. A mounting bracket is included since no J appears in the code. Operating pressure is 0.15 to 1.0 MPa (20 to 145 psi), proof pressure 1.5 MPa (215 psi), and temperature spans -5 to +70 C with no freezing.

Select GPF400C10D when air quality matters more than flow: the 0.01 um D element filters ten times finer than the 0.3 um M element in GPF400C10M-style codes, but rated flow falls from 1100 L/min to 600 L/min. If you cannot schedule manual draining, pick an A-suffixed variant with the automatic drain instead. For 1/2 in piping move up to the port-15 version of the same D-element specification.
The 0.01 um element at 99.9% efficiency gives the very clean air that measuring instruments and test benches demand.
Sub-micron oil mist and particles are stripped out before air reaches delicate pneumatic sensors and precision actuators.
Fit it as the last filtration stage after a coarser prefilter, using the included bracket to mount it close to the equipment it protects.
Port: 3/8 in, PT thread. Element: 0.01 um (D) at 99.9% efficiency. Rated flow: 600 L/min (inlet 0.7 MPa, outlet 0.5 MPa). 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. Metal bowl capacity: 89 cc. Drain: differential plus manual. Mounting bracket included.
The D option installs a 0.01 um element, ten times finer than the 0.3 um M element, so more of the filter media restricts the air path: rated flow is 600 L/min against 1100 L/min for the M element under the same 0.7 MPa inlet and 0.5 MPa outlet test conditions. It also uses the differential-plus-manual drain, so draining the 89 cc metal bowl is a manual task unless you order an automatic-drain variant.
