Genuine AirTAC mist separator, order code GPF40015AD from the GPF400 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
GPF40015AD combines the three biggest upgrades in the GPF400 ordering table: 1/2 inch port size 15 on PT thread, the D element rated 0.01 um at 99.9 percent efficiency, and an automatic drain on the 89 cc PC bowl. Rated flow for the D element is 600 L/min at inlet 0.7 MPa with outlet 0.5 MPa.
The A suffix lets the bowl empty itself of accumulated condensate, useful where nobody drains by hand, and the included bracket lets the 1/2 inch body stand on a frame or head a GA-series set. Pressure capability is unchanged across the series: 0.15 - 1.0 MPa (20 - 145 psi) operating, 1.5 MPa (215 psi) proof, -5 to +70 C without freezing.

Pick GPF40015AD over the GPF40015M sibling when oil aerosol must be cut to 0.01 um rather than 0.3 um - accept that rated flow drops from 1100 to 600 L/min. Over GPF40015D it adds the automatic drain, so condensate leaves the 89 cc PC bowl without manual rounds.
If your line is 3/8 inch, drop to the GPF40010 series; for metal or nylon bowls choose C or N instead of PC, for G or NPT threads add G or T, and if you mount inside a GA-series combination that provides its own hardware, append J to delete the bracket.
The 0.01 um D element at 99.9 percent efficiency polishes 1/2 inch PT supply air for pneumatic measuring fixtures and lab actuators sensitive to oil carryover.
Feed proximity-controlled valve terminals and pilot circuits through the D element so sub-micron oil mist cannot foul spools, while the automatic drain keeps the 89 cc PC bowl clear unattended.
On 1/2 inch packaging lines that run shifts without an operator at the FRL station, the A drain empties condensate automatically and the bracket holds the unit beside the machine.
Port 1/2 inch (15), PT thread; PC bowl, 89 cc, automatic drain (A); 0.01 um D element, 99.9 percent efficiency; rated flow 600 L/min at inlet 0.7 MPa and outlet 0.5 MPa; operating pressure 0.15 - 1.0 MPa (20 - 145 psi); proof pressure 1.5 MPa (215 psi); temperature -5 to +70 C, no freezing; bracket included.
The D suffix specifies the finer 0.01 um element, which is more restrictive than the 0.3 um M element, so rated flow is 600 L/min against 1100 L/min for M. If your 1/2 inch line needs the higher flow and 0.3 um filtration is enough, order the M version and keep the automatic drain by adding A.
