Airtac GAF Filter GAF400C15JW
The AirTAC Airtac GAF Filter GAF400C15JW is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 5 µm, protecting downstream valves and tools. It has 1/2" ports and a 100 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF400C15JW
The GAF400C15JW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 100 cc metal bowl, while the 5 um HDPE core traps fine grain. It protects downstream valves and cylinders from contamination without regulating pressure or adding a gauge.
This 1/2in port model weighs 640 g and uses a metal bowl with both semi-auto and manual drains fitted. The 5 um element suits precision applications, and the unit carries no mounting bracket for panel-mount installations.

Specifications follow the official AirTAC GAF catalogue (pages 225-226). Air must not freeze in the unit. This is a filter only — it separates water and solid particles but does not set or hold a downstream pressure. To regulate pressure as well, use the matching GAFR400 filter-regulator.

A GAF has no regulator and no pressure gauge — there is no type, gauge or reflux code. Need to regulate pressure too? The matching GAFR400-15 is the same filter with a built-in regulator.

Figures are the end of the flow curve plotted in the AirTAC catalogue — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. A filter this size drops less pressure at flow than the same-body GAFR filter-regulator, so match it to your peak demand.

Where the Airtac GAF Filter GAF400C15JW Is Used
CNC coolant lines
Protect precision solenoid valves on CNC machines from water carryover and fine abrasive dust that would otherwise score spools and shorten service life.
Assembly station headers
Feed a 1/2in manifold serving multiple pneumatic screwdrivers and push cylinders on a workbench, keeping tool exhaust ports clear of condensate.
Instrument air pre-filtration
Polish compressed air ahead of sensitive flow meters or pressure transmitters, where the 5 um element removes particles that could clog orifices.
Is the Airtac GAF Filter GAF400C15JW the Right Filter?
Choose the GAF400 body when your line needs 3/8in or 1/2in ports with a 100 cc condensate bowl. The metal bowl (C) suits demanding environments, while the 5 um (W) element traps finer particles than the standard 40 um for precision valves. This model ships without a bracket (J) and uses PT port threads; the semi-auto plus manual drain pair gives you both automatic purging and a manual backup. If you need pressure control, step up to the GAFR400-15 filter-regulator instead. The GAF400's 8000 L/min flow envelope is 1.33x the GAF300's 6000 L/min curve, letting you size up confidently.
Quick checklist
- ✓ Body size for your peak flow (1/2" here)
- ✓ Element 40 µm (general) or 5 µm (fine)
- ✓ Bowl material: PC (blank), Metal (C), Nylon (N)
- ✓ Drain: semi-auto + manual, or automatic
- ✓ Bracket kept or removed (J)
- ✓ Need pressure control too? Use GAFR400
Installation & Maintenance Notes
- check Install with the airflow arrow: IN to OUT, bowl accessible.
- check Place the filter FIRST in the air-prep train, ahead of any regulator or lubricator.
- check Keep pressure at or below the 1.5 MPa (215 psi) proof limit.
- check Drain condensate before the 100 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 640 g unit on its bracket, not on the tubing.
This is a filter only — it removes water and solid particles but adds no pressure control and no lubrication. Add a GAR regulator, a GAL lubricator, or step up to the GAFR400-15 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF400C15JW FAQ
This filter-only unit has a 5 um filtering grade, a working pressure range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi), and a temperature range of -5 to 70 C. The drain bowl holds 100 cc and the unit weighs 640 g, with a flow curve plotted to 8000 L/min.
The GAF400C15JW ships with both drain types fitted: the semi-auto drain purges condensate automatically when pressure drops, while the manual drain lets you empty the bowl on demand. This dual setup gives you automatic protection plus a reliable backup for scheduled maintenance.
