About the Airtac GC FRL Unit GC300C15AF1K
The AirTAC GC300C15AF1K is a G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one set. This size 300 set is ported PT1/2, carries the standard 40 um filter element with an automatic drain on the filter bowl, a square pressure gauge scaled in MPa, and a reverse (check) valve fitted on the regulator outlet. In use it removes water and particulate from compressed air, holds a set downstream pressure, and meters oil mist into the air line in a single assembly.
This is a genuine AirTAC part from the G-series air-treatment range, which runs from size 200 to 600 with PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge options and an optional mounting bracket; bowls on the 200 to 400 sizes are polycarbonate. Maximum working pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than one rated figure, so we confirm the datasheet and sizing figures on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-C1 filter, GR300-C1 regulator and GL300-C1 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the Airtac GC FRL Unit GC300C15AF1K Is Used
Automated assembly press circuit
Feeds filtered, regulated and lubricated air to the clamping and forming cylinders of a pneumatic assembly press. The fitted check valve helps hold the regulator setting when upstream supply dips during peak plant demand.
Carton packaging line
Supplies the stopper, pusher and flap cylinders along a carton sealing conveyor. One set keeps the valve-bank air clean, the pressure steady for repeatable cylinder strokes, and the line oiled for cylinder life.
Robotic weld cell air preparation
Prepares the air feeding a robotic weld cell's tool clamps and dressers. The square MPa-scaled gauge lets technicians read and set line pressure in the units used across the plant.
Is the Airtac GC FRL Unit GC300C15AF1K the Right Station?
The size 300 step gives a 1/2 in port and a larger unit than size 200; step up to size 400 or 600 when the line needs a bigger port and more flow capability. The A in the code orders the automatic drain, so the filter bowl drains itself during operation; with the automatic drain fitted, the regulator adjusts from 0.15 to 0.9 MPa (20 to 130 psi) and maximum inlet pressure is 1.0 MPa (145 psi). The 40 um element is the standard grade, and the F1 code orders the square gauge with an MPa scale. The K adds the reverse (check) valve; thread options are PT (this code), G (BSPP) and NPT, and a mounting bracket can be ordered. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-C1 regulator with a GF300-C1 filter on that branch.
Airtac GC FRL Unit GC300C15AF1K FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet and check the size 300 set against your application on request.
The default is a differential-pressure drain, which works off the pressure drop across the filter. A orders the automatic drain fitted on this code, and M orders manual drainage, which suits lines with intermittent flow. Drain type also sets the regulator range: with the automatic drain this set adjusts 0.15-0.9 MPa (20-130 psi), while a manual-drain version adjusts 0.05-0.9 MPa (7-130 psi).
