About the Airtac GPF Oil Mist Separator GPF400C15D
The AirTAC GPF400C15D pairs the finest element in the GPF400 range with a metal bowl on a 1/2 in (15) PT-threaded port. The D option selects the 0.01 um element, which captures oil mist and ultra-fine particles at 99.9% efficiency - a full class finer than the 0.3 um M element - making it the code to specify ahead of precision valves, sensing circuits and coating work.
That filtration depth has a sizing consequence: the D element is rated at 600 L/min (inlet 0.7 MPa, outlet 0.5 MPa), well below the 1100 L/min of the M version, so check your line consumption against 600 L/min before ordering. The differential + manual drain (blank A position) suits lines attended by operators, and the metal bowl plus included bracket let the unit mount alone or in GA-series two- and three-unit sets. Operating pressure is 0.15 to 1.0 MPa (20 to 145 psi).

How to choose
Choose GPF400C15D when 0.01 um cleanliness on a 1/2 in line outweighs flow capacity, and your crew can handle periodic manual draining. If you need higher flow instead of finer filtration, GPF400C15M keeps the metal bowl and adds the 1100 L/min M element. If nobody is on site to drain condensate, step up to the automatic-drain variant GPF400C15AD; for a bracketless build of the same filter, order GPF400C15JD.
Applications
Precision pneumatic circuits
The 0.01 um element at 99.9% efficiency protects solenoid valves, proportional controls and delicate actuators that clog or stick on oil mist from a 1/2 in supply.
Laboratory and test benches
On lab air supplies where oil carryover ruins results, the metal-bodied D-element filter on a PT-threaded port gives a clean-air stage at 0.15 to 1.0 MPa.
Coating and printing heads
Spray, ink and print heads demand particle-free air; the 600 L/min rating covers these low-consumption circuits while removing ultra-fine contamination.
FAQ
What are the key figures of the GPF400C15D?
Port 1/2 in (15), PT thread; metal bowl with 89 cc capacity and differential + manual drain; 0.01 um element 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); catalog weight is listed as 620 g / 627 g across variants, so confirm the exact figure on the datasheet. Bracket included.
How does the D element change sizing compared with the M element?
The D option filters to 0.01 um but is rated at 600 L/min, while the M element (0.3 um) flows 1100 L/min under the same 0.7 MPa inlet / 0.5 MPa outlet conditions. Size the GPF400C15D to your actual consumption so the finer element does not become the bottleneck of the 1/2 in line.
