The AirTAC Airtac GAF Air Filters GAF20008T 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.
The AirTAC GAF20008T is a compressed air filter and nothing more: it strips liquid water and solid dirt out of the line, and it has no regulator, no pressure gauge and no adjusting knob. Incoming air passes a diversion passage that spins the flow, so condensate and grit are thrown into the 25 cc drain bowl while the 40 um HDPE element traps the fine grain. This is the compact GAF200 body, built around 1/4in ports with a 200 g mass, so mount it on the included bracket or a panel instead of letting the tubing carry its weight. The ports are cut to NPT thread, and the drain station combines a semi-automatic dump with a manual push valve for a quick purge.

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.

Feed a pneumatic clamp or small fixture on a workbench: the 1/4in NPT ports suit short drops, and the 25 cc bowl catches water that condensed in the shop line overnight.
One compact machine valve or a pair of small cylinders get cleaner feed air, with the 40 um element screening scale and pipe debris before they can jam a spool.
A lab or prototype rig drawing a few hundred litres per minute sits well inside the 3000 L/min curve envelope, and the included bracket fixes the filter to the rig frame.
Pick the GAF200 body when the branch draws modest air; if demand grows, the GAF300 is the next body up, fitting 1/4in through 1/2in ports with its curve plotted to 6000 L/min rather than 3000. Bowl options are the PC bowl on this model, a C metal bowl or an N nylon bowl, and for aggressive surroundings you should confirm material compatibility from the datasheet before ordering. The blank drain position on this SKU means both semi-automatic and manual drains are fitted, while an A code swaps in an automatic drain for unattended lines; leaving out the J code keeps the mounting bracket on the unit. This T-suffix version carries NPT ports, so match your fittings and seals to NPT, since a blank code means PT and G means ISO G. The standard 40 um element suits general shop air; add the W suffix for a 5 um element when feeding finer components, accepting more frequent element checks. When the circuit also needs a fixed downstream pressure, order the matching GAFR200 or a separate GAR, because a GAF alone never regulates. Proof pressure of 1.5 MPa (215 psi) against the 0.9 MPa top of the rated range leaves this filter with roughly a 1.67x overpressure margin, a burst-test figure and not permission to run above the working range.
Quick checklist
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.
It is a 40 um compressed air filter with a rated working range of 0.15-0.9 MPa (20-130 psi), a proof pressure of 1.5 MPa (215 psi) and a temperature window of -5 to 70 C, and it must not freeze. The drain bowl holds 25 cc of condensate, the complete unit weighs 200 g, and the ports are 1/4in with NPT thread.
The T sets the port thread standard to NPT, the American tapered pipe form, so use NPT-compatible fittings and sealing method on both connections. It is a thread code only: this filter has no pressure gauge, so no gauge scale is attached to the code. A blank code would give PT and G would give ISO G thread.
