The AirTAC GC300-08 AirTAC F.R.L. Combination, G1/4, 5 um Filter is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/4" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC300-08 is a three-piece AirTAC F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. It cleans compressed air of water and particulate down to 5 um, regulates downstream pressure across a 0.15-0.9 MPa (20-130 psi) adjustment range, and meters oil mist to downstream equipment. This configuration carries a G1/4 (BSPP) port, a differential-pressure drain on the filter bowl, a round gauge reading in psi, a fitted reverse/check valve, and a mounting bracket. The polycarbonate bowls suit the -5 to 70 C non-freezing operating range, with a maximum inlet pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, a choice of 40 um or 5 um filtration, automatic, manual or differential-pressure drains, and gauges scaled in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.
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.

Feeds point-of-use drops on a vehicle assembly line where one set filters, regulates and lubricates the air supplying impact wrenches and nutrunners at each station.
Prepares air for the cylinders and grippers on a carton-packing conveyor, holding a steady regulated pressure while the 5 um grade protects tight-tolerance valve spools.
Conditions the air feeding spray guns in a finishing booth: the 5 um filtration reduces water and particulate carry-through while the lubricator supports the gun trigger mechanism.
Size and port set the flow capacity: step up from 200 to 300, 400 or 600 as your air demand grows, with this unit at size 300 on a G1/4 port. Choose the filter grade - 40 um standard or 5 um (W) where finer protection matters, as fitted here. Pick the drain: differential-pressure (default, as on this unit), automatic, or manual. Select the gauge scale - MPa, psi or bar - and the gauge style: the embedded square gauge is standard, with an external round gauge optional (fitted here, psi scale). Thread is PT as standard; G (BSPP) and NPT are order options, and this unit carries G. A reverse/check valve (K) and bracket are fitted on this code. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
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 publishes flow for this series as curves, not as a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow data from the datasheet and check the sizing against your demand before you order.
The W code in GC30008C2WGK selects the 5 um element in place of the 40 um standard. The finer grade suits downstream equipment such as precision valves, spray equipment or instrumentation where finer particulate and water removal is wanted; the 40 um grade remains available on other codes in the same size.
