Airtac GAF Filter GAF50020JW
The AirTAC Airtac GAF Filter GAF50020JW 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 3/4" ports and a 108 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF50020JW
The GAF50020JW is a filter-only unit that spins incoming air to throw liquid water and solid particles into its 108 cc drain bowl, while the 5 um HDPE element traps fine grain. It has no regulator, no gauge, and no lubricator - it cleans the air but does not control pressure.
This 3/4in model weighs 680 g and is rated for 0.15-0.9 MPa (20-130 psi) with a proof pressure of 1.5 MPa (215 psi). The 5 um element suits precision valves or instrument air, and the semi-auto plus manual drain gives you both automatic condensate release and a manual override.

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 GAFR500 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 GAFR500-20 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 GAF50020JW Is Used
Machine header feed
Protect a 3/4in header supplying multiple pneumatic stations on a production line, removing water and solids before they reach valves and actuators.
Instrument air prep
Use the 5 um element ahead of sensitive instrumentation or precision controls where fine particle carryover could cause drift or wear.
Dusty plant air
In environments with visible dust or condensate, the diversion structure and 108 cc bowl reduce maintenance frequency on downstream components.
Is the Airtac GAF Filter GAF50020JW the Right Filter?
Choose this GAF500 body for a 3/4in port line; it sits between the GAF400 (100 cc bowl, 8000 L/min curve) and the GAF600 (205 cc bowl, 12000 L/min curve). The PC bowl is a build choice - confirm compatibility for aggressive environments since no chemical data is printed. The semi-auto plus manual drain handles normal duty; the J code means no bracket is included, so plan a panel mount or use existing hardware. The 5 um element traps finer particles than the 40 um standard, and the PT thread matches common local fittings. If you also need a set pressure, the matching GAFR500-20 adds a regulator. The GAF500's 108 cc bowl holds about 1.7x the condensate of the GAF400's 100 cc bowl.
Quick checklist
- ✓ Body size for your peak flow (3/4" 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 GAFR500
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 108 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 680 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 GAFR500-20 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF50020JW FAQ
It is a filter-only unit with a 3/4in port, 5 um filtering grade, and a 108 cc drain bowl weighing 680 g. Working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and temperature range is -5 to 70 C. The flow curve is plotted to 9000 L/min.
The J means the mounting bracket is NOT included. You need a panel mount or an existing bracket. The unit still has the semi-auto plus manual drain and the 5 um element; it is a filter only, so it does not regulate pressure.
