About the AirTAC GC300-08 FRL Unit (GC30008C1)
GC30008C1 is an AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator installed together to clean, regulate and oil a compressed-air line. At size 300 with 1/4 in PT ports, this code specifies the default differential-pressure drain, standard 40 um filtration, and the optional external round gauge with an MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi); the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi); working temperature 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 offers differential-pressure, automatic or manual drain, 40 um standard or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scale, and G (BSPP) or NPT thread options; at size 300 the filter bowl is polycarbonate (PC). Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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: GF300-08 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 (GC30008C1) Is Used
Machine-tool clamping circuits
In a machining cell with pneumatic vises and clamps, the unit filters the shop supply, sets a stable clamp pressure and meters oil to the cylinders, while the MPa gauge shows the set pressure at a glance.
Maintenance-shop air-tool drops
A plant maintenance drop feeding impact guns, ratchets and grinders gets filtered, regulated and lubricated air, with the gauge confirming working pressure before tools are coupled.
Truck and bus service bays
In commercial-vehicle workshops the unit conditions the supply to impact wrenches and tire-service stations; the visible MPa gauge supports the bay pressures that service procedures call out.
Is the AirTAC GC300-08 FRL Unit (GC30008C1) the Right Station?
Step up from 200 to 300 when your line is plumbed in 1/4 in and your demand sits mid-range; the 400 and 600 sizes carry bigger ports and more flow. The drain here is the default differential-pressure type; automatic (A) and manual (M) versions are orderable if your maintenance routine calls for them. The 40 um element is the standard grade - the W code fits the finer 5 um element. This code adds the external round gauge in MPa scale; the embedded square gauge is the base option and psi or bar scales are available. PT is the standard thread on this code, with G (BSPP) and NPT as catalogue options; a bracket can be ordered separately. 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 (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 0.15 - 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008C1) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not state one number here. Tell us your required flow and working pressure and we will confirm sizing against the datasheet on request.
It selects the optional external round gauge with an MPa scale alongside the standard regulator set-up. The embedded square gauge is the base option, and psi or bar scales are also available - tell us which scale your team reads and we will match the order code.
