Airtac GAF Filter GAF400N15JW
The AirTAC Airtac GAF Filter GAF400N15JW 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 GAF400N15JW
The GAF400N15JW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 100 cc nylon drain bowl, while the 5 um HDPE core traps fine grain. It cleans the air; it does not regulate pressure and carries no gauge.
This 1/2in-port model weighs 640 g, placing it in the mid-size GAF400 class where a proper panel or frame mount is needed rather than support from the tubing. Its nylon bowl is a build choice for the environment, and you should confirm compatibility for aggressive surroundings since no chemical or temperature data is printed.

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 GAF400N15JW Is Used
Precision Valve Protection
Feed a bank of precision pneumatic valves on a machining center with 5 um filtered air, keeping fine abrasive dust out of spool and poppet clearances.
Instrument Air Pre-Filter
Protect sensitive instrumentation or gauges downstream by removing water droplets and solid grain before the air reaches calibrated devices.
Machine Tool Line
Install on a 1/2in line feeding a single machine tool with multiple actuators, where the 100 cc bowl supports a full shift before manual draining.
Is the Airtac GAF Filter GAF400N15JW the Right Filter?
Choose the GAF400 body when 1/2in ports and a 100 cc drain bowl fit your line; it sits between the GAF300 (60 cc bowl, 6000 L/min curve) and the GAF500 (108 cc bowl, 9000 L/min curve). The nylon bowl here is a material choice, while the 5 um element (W) traps finer particles than the 40 um standard at the cost of more frequent element service. This unit ships without the mounting bracket (J), so plan for a panel mount or an existing bracket, and match your fittings to the PT port thread. If you also need a set pressure, use the matching GAFR400-15 filter-regulator instead. The 100 cc drain bowl holds about 1.67x the condensate of the GAF300's 60 cc bowl, meaning fewer drain interventions at this size.
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 GAF400N15JW FAQ
This is a filter-only unit with 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. It has a 100 cc drain bowl, weighs 640 g, and its flow curve is plotted to 8000 L/min.
The J code means the mounting bracket is omitted, so you must use a panel mount or an existing bracket. The N code means the bowl is made of nylon, which is a build choice; the common specification is identical to PC or metal bowls, so confirm compatibility for your specific environment.
