The AirTAC Airtac GAF Air Filters GAF30015G 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 AirTAC GAF30015G is a compressed air filter, not a pressure controller: there is no adjusting knob, no gauge and no lubricator anywhere on this unit. Incoming air is spun through a diversion structure so liquid water and solid particles are flung out into the drain bowl, while the 40 um HDPE element traps the finer grain before it can reach valves, cylinders or air tools downstream. This variant carries a 1/2in port cut with G thread, a 60 cc condensate bowl and a 360 g body, and its flow curve is plotted to 6000 L/min. Both a semi-auto drain and a manual drain screw are fitted, and a mounting bracket comes included in the box. Rated from 0.15 to 0.9 MPa (20-130 psi), it works as the first stage of protection on a machine air supply.

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.

A 1/2in supply feeding directional valves and clamping cylinders on CNC periphery equipment stays dry when the 60 cc bowl is emptied on schedule.
Carton sealers and wrap stations run compressed air for long shifts; the 40 um element keeps grit out of actuator ports between maintenance windows.
Actuated diverters along a handling line need clean air at modest flow, which this body's 6000 L/min envelope comfortably covers.
Port code 15 puts a 1/2in connection on the mid-size GAF300 body. If your circuit is smaller, the GAF200 covers light lines with its 3000 L/min envelope; if you need more condensate reserve, the GAF400 holds 100 cc instead of this body's 60 cc. This SKU keeps the general-purpose 40 um element; pick the W suffix when precision valves call for a 5 um element. The blank drain position means a semi-auto drain and a manual drain screw are both installed, so someone should check the bowl on a schedule; the A variant handles unattended wet lines automatically. A mounting bracket is supplied, the bowl is polycarbonate, and the G-thread ports should be matched with the same thread standard on your fittings; metal C and nylon N bowls are separate SKUs. When the circuit also needs a set pressure, the matching GAFR300-15 adds a regulator to the same filter body, since this filter only cleans the air. For sizing, weigh the envelope: the curve here is plotted to 6000 L/min, exactly 2x the 3000 L/min plotted for the GAF200, so double the flow demand is the moment to step 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.
It is a 1/2in G-thread air filter with a 40 um filtering grade on an HDPE core. The working pressure range is 0.15-0.9 MPa (20-130 psi), proof pressure is 1.5 MPa (215 psi), and the temperature range is -5 to 70 C. The drain bowl holds 60 cc of condensate and the unit weighs 360 g.
The blank drain code fits two mechanisms at once: a semi-auto drain that discharges collected water when the line is depressurized, and a manual screw for emptying the 60 cc bowl whenever an operator chooses. Where the line never stops and moisture loads are heavy, the GAF30015A swaps in an automatic drain so nobody has to intervene.
