Airtac GAF Filter GAF20008A
The AirTAC Airtac GAF Filter GAF20008A is a genuine compressed-air filter. Its diversion structure spins the air to separate liquid water and trap solid particles down to 40 µm, protecting downstream valves and tools. It has 1/4" ports and a 25 cc drain bowl. It is a filter only — it does not regulate or set pressure.

About the Airtac GAF Filter GAF20008A
The GAF20008A is a genuine AirTAC air filter that spins incoming air to throw liquid water and solid particles into its 25 cc drain bowl, while the HDPE core traps fine grain. It is a filter only, with no regulator or pressure gauge, and it protects downstream valves and tools from contamination.
This model has a 1/4in port, a 40 um filter element, and an automatic drain that clears condensate without manual attention. Weighing just 200 g, it suits small jigs and single-valve protection, and its flow curve is plotted to 3000 L/min for relative sizing against larger bodies.

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 GAFR200 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 GAFR200-08 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 GAF20008A Is Used
Protect a precision jig
Mount the GAF20008A ahead of a small clamping jig on an assembly bench. Its 40 um element stops rust and pipe scale from scoring precision locating pins.
Guard a single solenoid valve
Feed one pilot-operated valve on a packaging line with clean, dry air. The automatic drain clears water so the valve spool does not stick overnight.
Service a portable air tool
Use it on a mobile cart feeding a pneumatic screwdriver. The 200 g body is light enough for the cart frame, and the 25 cc bowl is easy to inspect.
Is the Airtac GAF Filter GAF20008A the Right Filter?
Choose the GAF200 body for small machines or individual pneumatic components, and step up to a GAF300 (60 cc bowl, curve to 6000 L/min) when a line needs more condensate capacity. The PC bowl suits general industrial air, while the automatic drain (A) handles wet or unattended lines without manual checks. The included bracket simplifies panel mounting, and the PT thread matches common local fittings; for pressure control, pair it with a GAR regulator or upgrade to the GAFR200-08 filter-regulator. The 1.5 MPa proof pressure is about 1.67x the 0.9 MPa top of the working range, giving a clear overpressure margin for burst safety.
Quick checklist
- ✓ Body size for your peak flow (1/4" 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 GAFR200
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 25 cc bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Support the 200 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 GAFR200-08 filter-regulator as your air-prep needs grow.
Airtac GAF Filter GAF20008A FAQ
The GAF20008A is a filter-only unit with a 40 um HDPE element, a 1/4in PT port, and a 25 cc drain bowl. It weighs 200 g and its flow curve is plotted to 3000 L/min. Working pressure 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 automatic drain (A) opens by itself to expel accumulated condensate, so you do not need to open a manual petcock. It suits wet or unattended lines where regular manual draining is impractical. This model also includes the mounting bracket and uses a PC bowl.
