About the Airtac GC FRL Unit GC300C08MC1
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator ordered and installed as one set. This configuration is size 300 with a PT1/4 (1/4 inch) port, a manual drain on the filter bowl, standard 40 um filtration, and an external round MPa gauge on the regulator. Because the drain is manual, the bowl must be drained periodically as part of routine maintenance. The set filters water and particulate, regulates pressure and meters oil mist downstream, with a maximum working pressure of 1.0 MPa (145 psi) and an operating range of -5 to 70 C (non-freezing). The 300-size bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard; G and NPT as catalogue options), drain type, filter grade and gauge. Flow is published as curves rather than a single rated figure; we confirm the datasheet and sizing 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 GC300C08MC1 Is Used
Maintenance shop air drop
A point-of-use F.R.L. at a plant maintenance bench, where the manual drain suits a supervised work area and the round MPa gauge lets technicians set tool supply pressure visibly.
Pneumatic valve test bench
Supplies conditioned, regulated and lubricated air to valves under test on a workshop bench, with the manual-drain regulator adjusting down to 0.05 MPa for low-pressure test points.
Training rig air preparation
Equips pneumatic training and demonstration rigs, where the three separate filter, regulator and lubricator units make each conditioning stage visible and the manual drain teaches routine upkeep.
Is the Airtac GC FRL Unit GC300C08MC1 the Right Station?
Size 300 with a PT1/4 port suits 1/4-inch plumbed circuits; step down to size 200 for compact drops or up to 400/600 for larger porting and higher flow demand. The M code selects a manual drain, which suits accessible mounting points with light condensate load and a maintenance routine in place; choose the automatic or differential-pressure drain variants where bowl draining cannot be scheduled. With a manual drain, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), giving a lower minimum setting than the other drain types. Filtration is the 40 um standard. The round MPa gauge is external, with psi/bar scales available to order. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. Flow is published as curves, not a single rating, 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 GC300C08MC1 FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so no flow number appears on this page. Send us your required flow and working pressure and we will confirm the datasheet curve and check that size 300 with a PT1/4 port matches your application before you order.
The M code fits a manual drain, so the filter bowl is emptied by hand as part of scheduled maintenance - a good fit for accessible, lightly loaded installations. It also lowers the regulator's minimum set point: with a manual drain the adjust range is 0.05 to 0.9 MPa (7-130 psi), versus 0.15 to 0.9 MPa (20-130 psi) on the differential-pressure and automatic drain versions.
