About the Airtac GC FRL Unit GC300C15MC1K
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator delivered as one set. This GC300C15MC1K is built in size 300 with 1/2 in PT ports, a manual drain on the filter bowl, the standard 40 um filter element, an external round pressure gauge with MPa scale, and the K suffix fitting a reverse (check) valve. It strips water and particulate from compressed air, holds a set downstream pressure and meters oil mist into the line.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, with differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) element, embedded square or external round gauges in MPa, psi or bar scales, an optional reverse (check) valve and PT, G or NPT threads. Maximum inlet 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 a single rating; ask us and we will confirm the datasheet figures for your application.

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 GC300C15MC1K Is Used
Sort-conveyor gate and diverter cylinders
Power gate and diverter cylinders along a parcel-sort conveyor. The reverse (check) valve in this K version stops air flowing back through the set if upstream supply dips, while the filter, regulator and lubricator condition the air to the sortation actuators.
Automotive assembly cell tooling
Feed the pneumatic screwdrivers, clamps and lift-assists at an automotive assembly cell. One GC set at the cell drop gives clean, regulated, lubricated air, and the check valve keeps the downstream circuit isolated from backflow.
Pilot air for process control valves
Supply pilot air to control valve positioners and solenoids on a process line. The regulator holds a steady pilot pressure, the filter and lubricator condition the supply, and the check valve prevents the circuit back-driving the set.
Is the Airtac GC FRL Unit GC300C15MC1K the Right Station?
Size 300 with 1/2 in PT ports sits mid-range in the GC series; step up to 400 or 600, or down to 200, with the matching port if your line demands it. The K suffix adds a reverse (check) valve; order the same model without K if you do not need one. This version has a manual drain, which widens the regulator adjustment range to 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain versions adjust between 0.15-0.9 MPa (20-130 psi). The 40 um element is standard, with the W suffix giving 5 um. The C1 suffix specifies an external round gauge on MPa scale. PT is the standard thread, with G (BSPP) and NPT as order options. Because flow is published as curves rather than a single rated figure, 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 GC300C15MC1K FAQ
AirTAC publishes GC series flow data as performance curves, not as a single rated figure, so we do not quote a number here. Send us your working pressure and air demand and we will confirm the datasheet curve for this size 300, 1/2 in unit, including the effect of the check valve, against your application before you order.
It fits a reverse (check) valve so air cannot flow back through the set toward the filter and regulator when upstream supply drops. If you do not need that function, order GC300C15MC1 without the K; it is identical in every other respect, including the manual drain, 40 um element and MPa round gauge.
