About the AirTAC GC300-10 FRL Unit (GC30010MC1K)
The AirTAC GC series is a three-unit F.R.L.: a separate air filter, pressure regulator and lubricator that together remove water and particulate, hold a set downstream pressure and add oil-mist lubrication to compressed air. This GC30010MC1K is the size 300 configuration with PT3/8 ports, the standard regulator adjusting 0.05-0.9 MPa (7-130 psi) with its manual drain, a 40 um filter element, the external round gauge on the MPa scale and, per the trailing K, a reverse check valve fitted to the set. Bowls at size 300 are polycarbonate; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus automatic or differential-pressure drains, a 5 um element (W), other gauge scales, G or NPT threads, an optional bracket and builds without the check valve. AirTAC publishes flow as curves rather than one rated figure, so we confirm flow and datasheet details 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 GC300-10 FRL Unit (GC30010MC1K)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GF300-10 filter, GR300-10 regulator and GL300-10 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 GC300-10 FRL Unit (GC30010MC1K) Is Used
Fleet-service bay air prep
Supplying impact wrenches, tire changers and lifting aids in a truck and van service bay, with the K build specified where the shop circuit calls for a reverse check valve on the drop.
Maintenance-rig tool circuits
Conditioning air on a mobile maintenance rig's tool circuit, where the technician relies on the MPa gauge for setting and the manual drain during end-of-day checks.
Press-side clamping circuits
Feeding clamp and ejector cylinders beside a stamping press, with the set built to the K code where the machine builder has specified a reverse check valve in the pneumatic circuit.
Is the AirTAC GC300-10 FRL Unit (GC30010MC1K) the Right Station?
This set matches the GC30010MC1 in body and function - size 300, PT3/8 ports, manual drain, 40 um element, standard regulator at 0.05-0.9 MPa (7-130 psi) and the round MPa gauge - but the trailing K specifies that a reverse check valve is fitted; the plain code omits it. Choose the K build where the circuit calls for one, and step to size 400 or 600 for heavier demand or 200 for light circuits based on the actual air demand.
Other decodable choices: automatic (A) or differential-pressure drain instead of manual, the 5 um (W) element, gauge scale in psi (2) or bar (3) or the embedded square gauge, G (BSPP) or NPT threads in place of PT, and an optional bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing against the application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC GC300-10 FRL Unit (GC30010MC1K) FAQ
AirTAC does not publish a single rated flow figure for the GC series; capacity appears as selection curves in the datasheet. Send us your line pressure and air demand and we will confirm the size 300 fit - or whether 200, 400 or 600 is the better step - against the datasheet before you order.
K specifies that a reverse check valve is fitted to this F.R.L. set; the plain GC30010MC1 code omits it. Choose the K build when your circuit calls for one, and we will confirm the valve detail against the datasheet if you need it spelled out for the installation.
