About the Airtac GPF Oil Mist Separator GPF400C15AD
The GPF400C15AD pairs the GP-series mist separator body with the finest filtration option in the range: a 0.01 um coalescing element rated 99.9 percent efficient. Because the D element is the most thorough grade, its rated flow is 600 L/min at 0.7 MPa inlet and 0.5 MPa outlet, so lines needing very clean air but modest flow suit this code best. The 1/2 inch PT ports fit standard tapered pipe threads, and the unit works from 0.15 to 1.0 MPa (20 to 145 psi) with a 1.5 MPa (215 psi) proof pressure.
Two options are spelled out directly in the order code: C selects the metal bowl over PC or nylon, and A adds an automatic drain that empties the 89 cc bowl without manual intervention. A mounting bracket is included unless the code carries J, and PT thread is standard with G and T variants for other standards.

How to choose
Choose this code when you need the D element (0.01 um) with automatic draining in a metal bowl on a 1/2 inch line. If your flow demand is higher and 0.3 um filtration is sufficient, the M-element GPF400C15AD's sibling GPF400C15AJM or bracketed GPF400C15AM passes up to 1100 L/min instead of 600 L/min. For PC or nylon bowls, look to the blank-bowl or N codes such as GPF400N15AD, and for G or NPT threads pick the G or T suffix versions.
Applications
Instrument air polishing
The 0.01 um element at 99.9 percent efficiency removes oil mist ahead of measuring instruments and pneumatic sensors that cannot tolerate oily carryover.
Unattended machining cells
The automatic drain (A option) continuously empties the 89 cc metal bowl, so the filter keeps working through long shifts without an operator draining it by hand.
Valve and actuator protection
Mounted on a 1/2 inch PT supply with the included bracket, the separator shields control valves and actuators from fine particles within the -5 to +70 C (no freezing) window.
FAQ
What are the key figures of the AirTAC GPF400C15AD?
Port 1/2 inch, PT thread; element D = 0.01 um at 99.9 percent 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); bowl capacity 89 cc; metal bowl with automatic drain; bracket included; temperature -5 to +70 C, no freezing.
How does the metal bowl and automatic drain combination affect daily use?
The C option selects a metal bowl, chosen over PC or nylon where impact resistance matters, and the A option means condensate drains automatically instead of requiring the standard differential plus manual drain routine, so the 89 cc bowl is emptied without operator action.
