About the AirTAC GC300-08 FRL Unit (GC30008MF1WK)
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one air-preparation set. This GC30008MF1WK is the size 300 set with PT1/4 (1/4 in) ports, a manual drain on the filter bowl, a 5 um filter element, an embedded square pressure gauge on the MPa scale, and a reverse check valve fitted. It removes water and particulate from compressed air, holds a set downstream pressure and meters oil mist into the line.
This is a genuine AirTAC part. Maximum inlet pressure is 1.0 MPa (145 psi); the regulator on this manual-drain set adjusts from 0.05 to 0.9 MPa (7-130 psi); working temperature is -5 to 70 C (non-freezing); the size 300 filter bowl is polycarbonate. The GC family is also offered in sizes 200, 400 and 600, with G (BSPP) or NPT thread options and a 40 um standard element. AirTAC publishes flow as capacity curves rather than one rated figure - 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 0.05 - 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 GC300-08 FRL Unit (GC30008MF1WK)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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: GF300-08 filter, GR300-08 regulator and GL300-08 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 GC300-08 FRL Unit (GC30008MF1WK) Is Used
Control-valve positioner supply
Feeds the positioner and pilot stages of a large process control valve, where the check valve holds the prepared-air leg under pressure and the 5 um element protects the positioner orifice.
Sorter diverter air supply
Serves the diverter and stopper cylinders on a parcel sorter, with the check valve preventing backflow from the manifold and the lubricator oiling the cylinders on each divert.
Test-rig clamp actuators
Supplies the hold-down clamps on a laboratory or QA test rig, giving clean 5 um air, a stable set pressure held by the check valve, and light lubrication for the clamp seals.
Is the AirTAC GC300-08 FRL Unit (GC30008MF1WK) the Right Station?
Choose the GC size (200/300/400/600) to match the port and air demand of the circuit; this size 300 set carries 1/4 in PT ports. The K suffix adds a reverse check valve, so order this code when backflow into the set must be blocked; drop the K if not. Manual drain (M) means the filter bowl is bled periodically, and the manual-drain regulator covers 0.05-0.9 MPa (7-130 psi). The W element filters to 5 um for air feeding fine valves and actuators; the 40 um standard element is a separate code. The square gauge reads in MPa; a bar-scale version is a separate code. Thread is PT as standard - G (BSPP) or NPT are separate catalogue codes. Flow is published as capacity curves, not a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008MF1WK) FAQ
AirTAC publishes F.R.L. capacity as flow curves rather than a single rated number, and the fitted check valve also affects the pressure profile across the set, so we do not quote a figure here. Share your line pressure and air consumption and we will confirm the datasheet curve before you order.
GC is the three-unit F.R.L. family, 300 is the size, 08 is the 1/4 in port, M is the manual drain, F1 is the embedded square gauge on the MPa scale, W is the 5 um filter element and K is the fitted reverse check valve. Thread is PT as standard; G (BSPP) and NPT versions are separate orderable codes.
