About the Airtac GC FRL Unit GC300C08MNK
GC is the AirTAC three-unit F.R.L. combination: a separate air filter, a pressure regulator and a lubricator assembled as one conditioned-air set. This GC300C08MNK is a size 300 set with 1/4 in PT ports, a manual drain on the filter bowl, the standard 40 um filter element and a reverse (check) valve fitted; no gauge is included in this code. The set carries compressed air at up to 1.0 MPa (145 psi) working pressure, and with the manual drain the regulator adjusts across 0.05-0.9 MPa (7-130 psi). Filter and lubricator bowls are polycarbonate at size 300, and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be specified with differential-pressure, automatic or manual drains, a finer 5 um (W) element, an embedded square gauge or an external round gauge with MPa, psi or bar scales, and G (BSPP) or NPT threads as catalogue options. AirTAC publishes flow for this series as curves rather than a single rating, so we confirm sizing and 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 0.15 - 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-C0 filter, GR300-C0 regulator and GL300-C0 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 GC300C08MNK Is Used
Stamping-cell clamp circuits
Filtering, regulating and lubricating the supply to pneumatic clamps and press auxiliaries on a metal stamping line, where the fitted check valve is part of the specified circuit and manual bowl draining slots into the shift maintenance round.
Robotic weld-cell grippers
Conditioning plant air for robot end-of-arm grippers and part clamps, with the regulator set to the cell working pressure and the lubricator feeding a light oil mist to the cylinder seals.
Packaging line sealing station
Supplying treated air to bagging and carton-sealing heads on a packaging conveyor, where a technician checks and drains the filter bowl as part of the planned stop.
Is the Airtac GC FRL Unit GC300C08MNK the Right Station?
Size and port set the air path: the 300 body with 1/4 in PT ports is the mid-size step, and moving to 200, 400 or 600 trades port size against the flow your line needs. Drain type is the main service decision - the manual drain here means an operator opens the bowl drain during routine rounds, while automatic and differential-pressure drains handle condensate without that walk-round. The 40 um element is the standard grade; choose the 5 um (W) element where downstream valves and cylinders need finer air. No gauge is fitted in this code - catalogue options are an embedded square gauge or an external round gauge with MPa, psi or bar scales. PT is the standard thread; G (BSPP) and NPT are available to order as specifications. Flow is published as curves, not a single rated figure, so 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-C0 regulator with a GF300-C0 filter on that branch.
Airtac GC FRL Unit GC300C08MNK FAQ
AirTAC publishes GC series capacity as flow curves against pressure rather than a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm the correct size and the datasheet figures on request.
The manual drain in this code brings the regulator adjustment range to 0.05-0.9 MPa (7-130 psi); sets with automatic or differential-pressure drains adjust across 0.15-0.9 MPa (20-130 psi). The K in the code means a reverse (check) valve is fitted.
