About the Airtac GPF Oil Mist Separator GPF40015D
The AirTAC GPF40015D is a GP-series oil mist separator in the 1/2 inch body size, built around the D element that strips oil mist and fine particles down to 0.01 um with 99.9% efficiency. Because that fine-grade element passes less air than the coarse grade, the rated flow is 600 L/min measured at 0.7 MPa inlet and 0.5 MPa outlet, and the unit operates on 0.15 to 1.0 MPa (20 to 145 psi) of clean compressed air.
The code decodes as 1/2 inch ports (15) with PT thread as standard, a transparent PC bowl holding 89 cc of condensate, and the standard differential plus manual drain. A mounting bracket is included, so the unit can be wall- or panel-mounted on its own, or it can join GA-series two- and three-unit combinations when you build a full air preparation train.

How to choose
Pick GPF40015D when your line is 1/2 inch and the downstream equipment needs sub-micron oil removal, for example before precision valves or sensors. If you only need general 0.3 um filtration, the sibling GPF40015M flows 1100 L/min versus this code's 600 L/min, so check your air consumption first. If you pipe the unit directly and do not need the bracket, order GPF40015JD instead; for 3/8 inch piping, step down to the 10 port version.
Applications
Clean air for instrumentation
Feeding 0.01 um filtered air at 0.15 to 1.0 MPa to pneumatic sensors and measuring devices, with the differential plus manual drain keeping the 89 cc PC bowl clear of accumulated condensate.
Paint and coating lines
Installing the separator as the final oil-mist stage before spray guns on a 1/2 inch PT supply, where oil carryover would ruin finish quality; confirm exact flow against the 600 L/min rating.
GA-series preparation sets
Slotting the GPF40015D, with its included bracket, into a GA-series two- or three-unit combination so filtration follows the filter-regulator in one compact assembly.
FAQ
What are the key figures of the GPF40015D?
Port 1/2 inch (15) with PT thread; element D, 0.01 um 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 with no freezing; PC bowl of 89 cc; differential plus manual drain; bracket included.
How does the D element differ from the M element in the 1/2 inch size?
Both fit the same GPF400 body. The D element (this code) removes particles and oil mist down to 0.01 um but is rated for 600 L/min, while the M element (0.3 um, code GPF40015M) is rated for 1100 L/min under the same 0.7 MPa to 0.5 MPa test conditions. Choose D when air purity matters more than flow capacity.
