Genuine AirTAC mist separator, order code GPF400C15AM from the GPF400 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
The AirTAC GPF400C15AM is a GP-series mist separator ordered with the full option set that matters most for unattended installations: a metal bowl (C), an automatic drain (A) and the 0.3 um element (M). The automatic drain expels collected condensate on its own, so the 89 cc bowl keeps working in lines where nobody walks past to press a manual drain. With PT thread on the 1/2 in (15) port, the unit handles 0.15 to 1.0 MPa (20 to 145 psi) and removes oil mist and fine particles at 99.9% efficiency.
Because the M element is the higher-flow option, this code is rated at 1100 L/min (inlet 0.7 MPa, outlet 0.5 MPa), so a 1/2 in supply line keeps its capacity downstream of the filter. A mounting bracket is included, and the unit can also join GA-series two- and three-unit combos.

Pick GPF400C15AM when your line needs 1/2 in ports plus unattended drainage and moderate filtration. Choose GPF400C15AD if you need the finer 0.01 um element, accepting the lower D-element flow, or GPF400C15M if a differential + manual drain is enough and you prefer the metal bowl without automatic draining. If a PC bowl is acceptable, the blank-bowl variant GPF40015AM costs less than this metal-bowl build.
The automatic drain keeps condensate out of the metal bowl during unmanned shifts, so the 0.3 um element protects downstream valves without end-of-shift draining.
At 1100 L/min rated flow, the M element suits 1/2 in lines feeding air tools and cylinders that would be starved by the 600 L/min D-element variant.
With the included bracket and PT thread, the unit mounts alone or joins GA-series two- and three-unit sets as the filtration stage.
Port 1/2 in (15), PT thread; metal bowl with 89 cc capacity and automatic drain; 0.3 um element at 99.9% efficiency; rated flow 1100 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.
The blank drain position in the ordering code gives differential + manual draining, which requires someone to operate it. The A option replaces that with an automatic drain, so the metal bowl empties itself - useful for the 89 cc bowl in continuous or unattended duty.
