About the AirTAC GC300-10 FRL Unit (GC30010MC1)
The AirTAC GC series is a three-unit F.R.L.: a separate air filter, pressure regulator and lubricator that together remove water and particulate, hold a set downstream pressure and add oil-mist lubrication to compressed air. This GC30010MC1 is the size 300 configuration with PT3/8 ports, the standard regulator adjusting 0.05-0.9 MPa (7-130 psi) with its manual drain, a 40 um filter element and the external round gauge on the MPa scale. Bowls at size 300 are polycarbonate; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, plus automatic or differential-pressure drains, a 5 um element (W), other gauge scales, G or NPT threads and an optional bracket. AirTAC publishes flow for the G series as curves rather than one rated figure, so we confirm flow and datasheet details 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 0.05 - 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: GF300-10 filter, GR300-10 regulator and GL300-10 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 GC300-10 FRL Unit (GC30010MC1) Is Used
Workshop bench air drops
A drop-fed F.R.L. at a maintenance bench supplying impact wrenches, air ratchets and blow guns, with the operator draining the bowl during daily checks and reading the setting off the MPa gauge.
Bottling conveyor pushers
Conditioning the air that drives bottle pushers and stopper cylinders along a bottling hall conveyor, where the line crew walks past and can drain the bowl on schedule.
Machine panel actuator banks
Feeding a bank of solenoid valves and small cylinders inside a machine cabinet, with the round MPa gauge giving the setter a clear pressure reference at the panel.
Is the AirTAC GC300-10 FRL Unit (GC30010MC1) the Right Station?
Size 300 with PT3/8 ports is the mid-range step in the G series; step to 400 or 600 for heavier demand or 200 for light circuits, matching the size to the demand rather than the pipe alone. This build has the manual drain (M): condensed water is released by hand as part of routine checks, which suits attended posts; choose automatic (A) or differential-pressure drainage where the bowl cannot be watched. With a manual drain the regulator adjusts 0.05-0.9 MPa (7-130 psi), and the C1 code adds the external round gauge with MPa scale.
Remaining choices: the 40 um standard or 5 um (W) element, round gauge scales in psi (2) or bar (3), the embedded square gauge on other variants, G (BSPP) or NPT threads instead of PT, and an optional bracket. AirTAC gives flow 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 (PT3/8" 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC GC300-10 FRL Unit (GC30010MC1) FAQ
AirTAC publishes G-series flow as selection curves rather than a single rated figure, so no honest l/min or SCFM number can be quoted here. Send us your line pressure and air demand and we will confirm the size 300 fit - or whether 200, 400 or 600 suits better - straight from the datasheet before you order.
The M in GC30010MC1 is the manual drain: the bowl is drained by hand during routine checks, which suits attended posts such as workshop drops. Automatic (A) drains the bowl on its own, and differential-pressure drainage is the catalogue default; note that with a manual drain the regulator adjusts 0.05-0.9 MPa (7-130 psi), versus 0.15-0.9 MPa (20-130 psi) on automatic or differential builds. We can confirm the right drain for your duty before you order.
