AirTAC GC300-08 FRL Unit (GC30008MC1K)
The AirTAC AirTAC GC300-08 FRL Unit (GC30008MC1K) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/4" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GC300-08 FRL Unit (GC30008MC1K)
GC30008MC1K is an AirTAC G-series three-unit F.R.L. combination: separate filter, regulator and lubricator built as one 300-size set with PT1/4 ports, with the K option fitting a reverse (check) valve so the line cannot back-feed through the set when supply is isolated. The filter uses the standard 40 um element with a manual-drain bowl, and with a manual drain the regulator adjusts over 0.05-0.9 MPa (7-130 psi). The round external pressure gauge on the MPa (1) scale is included.
This is a genuine AirTAC part. The GC series is offered in 200, 300, 400 and 600 sizes, with PT as the standard thread and G (BSPP) or NPT as catalogue options, automatic or differential-pressure drain alternatives, and 5 um fine-filter elements where specified. The 300-size bowls are polycarbonate (PC). Max inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm sizing and datasheet figures 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.

| 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)). |

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 (GC30008MC1K) Is Used
Pneumatic press cells
Feeding pneumatic press and clamping manifolds where the fitted check valve stops an isolated downstream zone from back-feeding the set during changeover or shutdown.
Injection molding plant
Treating air for core-pull cylinders and ejector circuits, with the manual drain worked into the shift-start walkaround and the check valve guarding each machine drop.
Bottle-handling conveyors
Supplying air to conveyor stopper and pusher cylinders on a bottling line, where the regulator holds a fixed setting and the lubricator keeps actuator seals conditioned.
Is the AirTAC GC300-08 FRL Unit (GC30008MC1K) the Right Station?
Size 300 with 1/4 in PT ports is the general-purpose step in the G-series; move to 200 for compact branches or 400/600 for larger mains. The K option here adds a reverse (check) valve - pick this code where a downstream zone must not push air back through the regulator when the supply valve is closed. Manual drain means scheduled bleeding by hand; choose A (automatic) or differential-pressure (blank) for unattended draining, which shifts the regulator range to 0.15-0.9 MPa (20-130 psi). Filter grade is the standard 40 um; the W code gives 5 um. The round MPa gauge is included; square-gauge and psi/bar scales are alternatives. PT is standard, with G (BSPP) and NPT orderable. Flow is published as curves, not a single rating - ask us to confirm sizing 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 (GC30008MC1K) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no single flow number is quoted here. Send us your line pressure and air demand and we will confirm sizing against the datasheet on request.
K means a reverse (check) valve is fitted, so air cannot flow backward through the set into the regulator when the upstream supply is shut off. The same unit without the K (GC30008MC1) has no check valve; pick the K code wherever an isolated downstream circuit must not back-feed the supply.
