About the AirTAC GC300-08 FRL Unit (GC30008F1G)
GC30008F1G is a GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator set up for 1/4 inch G (BSPP) ports in size 300. The filter stage carries the standard 40 um element with a differential-pressure drain, the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) and is read on the included square MPa gauge, and the lubricator meters oil mist into the downstream air. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C, and the filter and lubricator bowls are PC (polycarbonate) at this size.
This is a genuine AirTAC part. The G series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and can be ordered with automatic or manual drains, a 5 um filter element, alternative gauge scales, a reverse/check valve and G or NPT threads. AirTAC publishes flow as curves rather than a single rating, so we confirm the datasheet figures 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: GF300-08 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 (GC30008F1G) Is Used
Pneumatic clamping on machining fixtures
Conditions the air feeding clamp cylinders that hold workpieces on a machining centre, so the clamps see filtered, regulated, lightly oiled air all shift long.
Packaging line sealing jaws
Prepares the supply for the cylinder that drives heat-seal jaws on a bagging or wrapping line, keeping the jaw action consistent from start-up to shutdown.
Air supply to assembly-station valve manifolds
Feeds directional valves and small actuators on a manual assembly bench, with the lubricator stage protecting the moving parts of the tooling.
Is the AirTAC GC300-08 FRL Unit (GC30008F1G) the Right Station?
The main choice is size and port: size 300 with 1/4 inch G ports is the mid-range step; step down to 200 or up to 400/600 depending on the air demand of the circuit. Drain type is selectable - differential-pressure (fitted here), fully automatic, or manual - and the filter element is 40 um standard or 5 um with the W suffix. Gauge scale and thread (PT standard, G or NPT to order) are the other decodable options.
Because flow for this series is published as performance curves and not as one rated number, send us your line pressure and demand and we will confirm sizing against the datasheet before you order.
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 (GC30008F1G) FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
40 um is the default grade and suits general plant air protecting cylinders, valves and air tools. The 5 um W suffix is the choice when finer filtration is wanted; it is a decodable option on the same GC300 body and we can confirm details on request.
