About the Airtac GPF Oil Mist Separator GPF400C10AD
GPF400C10AD decodes as the AirTAC GP-series GPF400 mist separator in the most protection-focused bowl configuration: a metal (C) bowl with automatic drain (A), sized for 3/8 inch (10) ports with PT thread. The D element is the finer of the two choices, removing oil mist and particles down to 0.01 um at 99.9% efficiency, one decade finer than the M option.
Filtration that fine costs flow: rated capacity is 600 L/min at inlet 0.7 MPa and outlet 0.5 MPa, versus 1100 L/min for the M element, so line sizing must be checked against real air consumption. The unit works from 0.15 to 1.0 MPa (20 to 145 psi), tolerates 1.5 MPa (215 psi) proof pressure, operates between -5 and +70 C with no freezing, and ships with the bracket included, ready for standalone mounting or a GA-series combined set.

How to choose
Choose GPF400C10AD when the 3/8 inch port matches your line, condensate must leave the bowl on its own (A drain, no manual venting), and the environment calls for a metal bowl rather than PC or nylon - for example where a polycarbonate bowl would be a concern. Compare it with GPF400C10AMD-style M-element siblings if 0.3 um filtration is sufficient and you want the higher 1100 L/min rated flow, and with the J-code version of the same C10AD configuration if you do not need the mounting bracket.
Applications
Sensitive instrumentation air
The 0.01 um D element at 99.9% efficiency delivers near oil-free air to pneumatic gauges, sensors and precision actuators on 3/8 inch circuits, while the automatic drain keeps the metal bowl clear without operator intervention.
Laboratory and test-rig supply
Test benches running at 0.15 to 1.0 MPa (20 to 145 psi) benefit from sub-micron air quality; the metal bowl suits settings where a plastic bowl is undesirable, and the D-element rated flow of 600 L/min must be matched to bench consumption.
Packaging machinery final stage
As the last coalescing stage before packaging machine valves and cylinders, the automatic drain discharges accumulated condensate during cycles, and the included bracket mounts the unit beside the GA-series regulator and filter on 3/8 inch PT lines.
FAQ
What are the key figures for the AirTAC GPF400C10AD?
Port: 3/8 inch (code 10) with PT thread. Bowl: metal (C), 89 cc capacity, with automatic drain (A). Element: D, 0.01 um at 99.9% efficiency. Rated flow: 600 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). Temperature: -5 to +70 C, no freezing. Weight: 620 g or 627 g. Mounting bracket included.
Why does the D element reduce flow, and what does the metal bowl change?
The D element filters to 0.01 um instead of 0.3 um, so it is denser and passes less air: rated flow is 600 L/min versus 1100 L/min for the M element under the same inlet 0.7 MPa, outlet 0.5 MPa test condition. The C bowl is metal rather than the standard PC, and paired with the A code it drains automatically, so no manual blow-down of the 89 cc bowl is required in normal service.
