About the Airtac GC FRL Unit GC300C15C1K
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator delivered as one set, so the compressed air feeding your valves, cylinders and air tools is cleaned, regulated and oil-mist lubricated in the correct order. This GC300C15C1K is the 300 size with PT 1/2 ports. The filter stage carries the standard 40 um element with a differential-pressure drain, the regulator offers 0.15-0.9 MPa (20-130 psi) adjustment, and the K suffix adds a reverse (check) valve; an external round gauge on the MPa scale is fitted. Maximum working pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C non-freezing, and the 300-size filter and lubricator bowls are polycarbonate.
This is a genuine AirTAC part. The G-series is offered in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch and PT, G (BSPP) or NPT thread options, plus choices of drain type, filter grade, gauge and reverse valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet details against your application 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 GC300C15C1K Is Used
CNC machining-center pneumatics
Feeds clean, regulated and lubricated air to the tool-change cylinders, clamps and chip-ejection actuators on a CNC machining cell, with the check valve helping hold the downstream circuit.
Palletizing robot gripper supply
Prepares the air feeding vacuum and clamp grippers on a palletizing robot line, where consistent regulated pressure keeps pick-and-place cycles repeatable.
Paint-line spray supply
Filters, regulates and oils the air going to spray guns on a finishing line, protecting gun valves from water and particulate carryover.
Is the Airtac GC FRL Unit GC300C15C1K the Right Station?
The 300 size with PT 1/2 ports sits mid-range in the G-series: step up to 400/600 or down to 200 depending on the port size of your valve manifold and the flow your line needs. This code fixes a differential-pressure drain and the standard 40 um element; automatic or manual drain and the finer 5 um element are orderable variants. The gauge scale here is MPa, PT is the standard thread, and G (BSPP) or NPT are catalogue options to specify when ordering; a mounting bracket is optional. Because flow is published as curves and not a single rating, 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 GC300C15C1K FAQ
AirTAC publishes flow for the G series as curves, not as a single rated figure, so we do not quote a number on the page. Send us your operating pressure and demand and we will confirm the flow curve and full datasheet figures on request before you order.
The K suffix means a reverse (check) valve is fitted on this set; the same three-unit configuration is available without it on codes that carry no K. The other fixed choices in this code are the differential-pressure drain, the 40 um element, the round MPa gauge and the PT 1/2 thread.
