About the AirTAC GC300-08 FRL Unit (GC30008C1WK)
GC30008C1WK is an AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied as one matched set. This 300-size unit is threaded PT1/4, uses the differential-pressure drain on the filter bowl, carries the fine 5 um filter element, and includes the round external pressure gauge on the MPa scale. The K suffix means a reverse (check) valve is fitted, as specified in the AirTAC catalogue for this code.
This is a genuine AirTAC part. The G-series F.R.L. sets are offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) fine filtration, MPa, psi or bar gauge scales, and G(BSPP) or NPT thread options. Maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing. Flow is published by AirTAC as curves rather than a single rating, so ask us and we will confirm the datasheet figures for this exact model 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: GF300-08 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 (GC30008C1WK) Is Used
Paint spray booth air preparation
Feeds spray guns and air-assisted applicators on a finishing line, where the 5 um element and lubricator support consistent coating work at the gun.
Pneumatic clamping on a CNC fixture
Conditions and regulates the supply to clamp cylinders on a machining centre, with the regulator set to the fixture's clamping pressure.
Bottling line actuator supply
Filters, regulates and lubricates the air feeding gripper and pusher cylinders along a filling and capping line.
Is the AirTAC GC300-08 FRL Unit (GC30008C1WK) the Right Station?
The 300 size with 1/4 in port sits mid-range in the G-series: step down to 200 or up to 400/600 if your line needs a different port and flow band - match the size to the air consumption of the downstream circuit. Drain options are differential-pressure (fitted here), automatic or manual. This code already specifies the fine 5 um element; the standard grade is 40 um if your application tolerates coarser filtration. The round gauge here reads in MPa; psi or bar scales and an embedded square gauge are alternatives, and G(BSPP) or NPT threads can be ordered instead of the PT standard. 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 (GC30008C1WK) FAQ
AirTAC publishes flow for the G-series as curves rather than a single rated figure, so we do not quote a number here. Send us your working pressure and required flow and we will confirm the datasheet curve for this 300-size, 1/4 in set before you order.
With no drain letter in the code, the filter bowl uses the differential-pressure drain, which discharges when the pressure drop across the element builds up. The W in the code selects the 5 um fine element instead of the 40 um standard. Automatic (A) or manual (M) drains and either grade can be specified on other codes in the same series.
