The AirTAC Airtac GAF Filter GAF30015A 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 1/2" ports and a 60 cc drain bowl. It is a filter only — it does not regulate or set pressure.
The GAF30015A is a genuine AirTAC air filter that removes water and solid particles from compressed air lines using a diversion structure that spins the air before the HDPE element traps fine grain. This 1/2in port model has a 60 cc drain bowl and weighs 360 g, placing it in the mid-size GAF300 class.
This unit ships with a PC bowl and an automatic drain, so it suits lines where regular manual draining is impractical. The 40 um element handles general workshop air, and the included mounting bracket lets you secure the 360 g body to a panel or frame rather than supporting it from the tubing.

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 GAFR300 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 GAFR300-15 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.

Feed a 1/2in line serving a CNC lathe's air chuck and coolant valves, where the automatic drain removes condensate without stopping production for manual checks.
Protect a multi-fixture assembly bench with several pneumatic screwdrivers, keeping water and rust particles away from tool internals.
Clean the air feeding a spray gun's blow-off nozzle, where solid grain in the line would mark freshly prepared surfaces.
Choose the GAF300 body when you need 1/2in ports and a 60 cc condensate bowl, stepping up from the GAF200's 25 cc bowl if your line has higher moisture load. The automatic drain (A) replaces the semi-auto and manual drains, so it suits unattended or wet lines. This model keeps the mounting bracket and uses a 40 um element, while the PT thread standard matches common local fittings. If you also need to set a downstream pressure, use the matching GAFR300-15 filter-regulator instead. The GAF300's flow envelope plotted to 6000 L/min is 2x the GAF200's 3000 L/min curve, giving you clear headroom when sizing up.
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 GAFR300-15 filter-regulator as your air-prep needs grow.
The GAF30015A is a 1/2in port air filter with a 40 um HDPE element. Its working pressure range is 0.15-0.9 MPa (20-130 psi), with a proof pressure of 1.5 MPa (215 psi). It operates from -5 to 70 C and must not freeze. The drain bowl holds 60 cc and the unit weighs 360 g.
The automatic drain (A) expels collected condensate without manual intervention, making it ideal for unattended lines or locations where the bowl fills quickly. Unlike the semi-auto and manual drain versions, you do not need to open a valve by hand to empty the 60 cc bowl.
