About the AirTAC GC300-08 FRL Unit (GC30008MC1)
GC30008MC1 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. The filter uses the standard 40 um element with a manual-drain bowl, so the bowl is bled by hand during maintenance rounds. Because the drain is manual, the regulator adjusts over the wider 0.05-0.9 MPa (7-130 psi) range, and this set includes the round external pressure gauge on the MPa (1) scale. Max inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series comes 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). 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.

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 (GC30008MC1) Is Used
Textile weaving plants
Conditioning the air feed to looms and take-up cylinders, where a technician on the maintenance round manually drains the filter bowl at the start of each shift.
Fleet service bays
Air treatment at truck and bus repair bays feeding lift jacks and impact guns, with the manual drain letting technicians bleed moisture before the bay closes.
Test rig and lab benches
Supplying regulated, lubricated air to pneumatic test fixtures and calibration benches, where the round MPa gauge gives the operator a direct line-pressure readout.
Is the AirTAC GC300-08 FRL Unit (GC30008MC1) the Right Station?
Size 300 with 1/4 in PT ports suits general machine supply lines; step to 200 or 400 depending on the pipe run and the air path your equipment needs. The manual drain here means someone bleeds the filter bowl on a schedule; choose A (automatic) or leave the position blank (differential-pressure) if you want unattended draining, noting the regulator range changes accordingly. Filter grade is the standard 40 um; order the W variant for 5 um. The round MPa gauge is included in this code; square-gauge and psi/bar scale versions exist. PT thread is standard, with G (BSPP) and NPT orderable to match your piping. Flow is published as curves, not a single rating - 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 (GC30008MC1) 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.
The GC is a three-piece F.R.L.: separate filter, regulator and lubricator, so each function can be serviced or positioned individually. The two-unit GFC combines filter and regulator in one body and pairs it with a lubricator, saving panel space. Choose GC when you want fully separable stages or need to pipe the lubricator downstream of a longer run.
