About the Airtac GPF Oil Mist Separator GPF40015M
The GPF40015M order code pinpoints one configuration of the AirTAC GP-series GPF400 oil mist separator: the 15 port size for 1/2 inch lines, a PC (polycarbonate) bowl, the standard differential plus manual drain, an M element filtering to 0.3 um at 99.9% efficiency, and PT thread as shipped by default. Because the M element is chosen instead of D, rated flow is 1100 L/min (inlet 0.7 MPa, outlet 0.5 MPa), the higher of the two GPF400 element options.
Operating pressure spans 0.15 to 1.0 MPa (20 to 145 psi) with a 1.5 MPa (215 psi) proof pressure, and the unit runs from -5 to +70 C with no freezing. The 89 cc bowl gives condensate room between manual drain visits, and the included bracket lets the separator stand alone or join GA-series two- and three-unit combined sets.

How to choose
Pick GPF40015M when your air line is 1/2 inch and the task is removing oil mist and particles down to 0.3 um while keeping full rated flow of 1100 L/min. If you need finer 0.01 um filtration instead, order GPF40015D and accept the lower 600 L/min rated flow. For a 3/8 inch line, step down to the 10 port code such as GPF40010M, and for automatic condensate removal without manual drain effort, choose the A drain variant rather than this standard differential plus manual version.
Applications
General plant air polishing
Installed after a filter-regulator on 1/2 inch headers, the 0.3 um element at 99.9% efficiency strips oil mist from compressed air feeding general production equipment, with the 89 cc PC bowl and manual drain handling condensate at working pressure up to 1.0 MPa.
Pneumatic tool and valve supply
Clean, oil-mist-free air at 1100 L/min rated flow protects directional valves and air tools on 1/2 inch PT-threaded circuits, and the included bracket allows the separator to bolt directly to a machine frame or panel.
GA-series modular air preparation
With its bracket fitted, this unit joins GA-series two- and three-unit combinations, so a 1/2 inch FRL-style set can be built with the GPF400 as the final coalescing stage before air reaches actuators or instrumentation.
FAQ
What are the key figures for the AirTAC GPF40015M?
Port: 1/2 inch (code 15) with PT thread. Element: M, 0.3 um at 99.9% efficiency. Rated flow: 1100 L/min at inlet 0.7 MPa and outlet 0.5 MPa. Operating pressure: 0.15 to 1.0 MPa (20 to 145 psi), proof pressure 1.5 MPa (215 psi). Bowl: PC, 89 cc capacity, differential plus manual drain. Weight: 620 g or 627 g depending on drain variant. Temperature: -5 to +70 C, no freezing. Mounting bracket included.
How does the standard drain on this code work, and when should I upgrade?
The GPF40015M carries the standard drain, which is a differential-pressure drain combined with manual operation: condensate collects in the 89 cc PC bowl and is released when you actuate the drain manually. If your installation is unattended or drains are hard to reach, select the A-code variant of the same GPF400 separator, which changes the drain to fully automatic.
