About the AirTAC GC300-15 FRL Unit (GC30015MC1K)
The GC series is a three-unit air preparation set: a separate filter, regulator and lubricator, so compressed air is cleaned, regulated and oil-misted in one supply. This GC30015MC1K is the 300 size with PT1/2 ports, a manual drain on the filter bowl, a standard 40 um filter element, an external round gauge reading in MPa, and the K suffix specifying a reverse (check) valve fitted as part of the set. Max working pressure is 1.0 MPa (145 psi), the manual-drain regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), the 300-size bowls are polycarbonate (PC), and the operating range is -5 to 70 C.
It is a genuine AirTAC part. The G series runs from size 200 to 600, with larger sizes giving larger ports and more flow, and options including automatic or differential-pressure drains, a 5 um element (W) and G (BSPP) or NPT threads. Flow is published as curves rather than a single rating, so we confirm the datasheet figures for 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 0.05 - 0.9 MPa (7 - 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.
Model Code: AirTAC GC300-15 FRL Unit (GC30015MC1K)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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: GF300-15 filter, GR300-15 regulator and GL300-15 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 GC300-15 FRL Unit (GC30015MC1K) Is Used
Robotic weld cell preparation
Prepares the air feeding a robotic spot-welding cell's gun clamps and positioners, with the check valve specified in the set and the 40 um element protecting the cell's valves.
Pneumatic control cabinet feed
Mounted as the supply set on a machine control cabinet, giving a single filtered, regulated and lubricated take-off for the solenoid valve manifold inside.
Press shop air drops
Installed at point-of-use drops in a stamping and press shop, where attendants drain the bowls on their rounds and the regulator holds a fixed working pressure.
Is the AirTAC GC300-15 FRL Unit (GC30015MC1K) the Right Station?
Size 300 with PT1/2 ports sits mid-range in the GC family; step to 200, 400 or 600 as your pipe and demand change. The M suffix means a manual drain, which suits attended lines and widens the regulator range to 0.05-0.9 MPa; choose A (automatic) or the differential-pressure default for unattended duty. The 40 um element is the standard grade - order the W variant for 5 um. The K suffix fits a reverse (check) valve in this set; drop the K if you do not want it. This set carries a round external gauge on the MPa scale; psi and bar scales exist in the range. PT thread is the standard, with G (BSPP) and NPT as catalogue options. Because flow is published as curves, not one rating, ask us to confirm sizing before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 0.05 - 0.9 MPa (7 - 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC GC300-15 FRL Unit (GC30015MC1K) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Share your line pressure and air demand and we will confirm the sizing and datasheet figures for this 300-size, PT1/2 set on request.
K specifies that a reverse (check) valve is fitted as part of this GC set. The same configuration without the K, such as the GC30015MC1, omits it. If you need the valve's behaviour confirmed for your circuit, we will check the datasheet on request.
