The AirTAC GC30008LF2WK AirTAC F.R.L. Combination, PT1/4, 5 um 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 GC30008LF2WK is an AirTAC GC300 three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set, giving filtration, regulation and lubrication in a single mounting. This configuration is sized for 1/4 in PT ports, carries the 5 um filter element (code W) instead of the standard 40 um, uses the differential-pressure drain as its default bowl drain, and is built as the low-pressure regulator type. It ships with the embedded square gauge scaled in psi, a reverse/check valve fitted, and a mounting bracket included. The filter and lubricator bowls are polycarbonate (PC); only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and thread options in PT (standard), G (BSPP) and NPT. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

A spray booth or finishing cell drawing plant air through this unit gets water and particulate removed at 5 um, air held at the low pressure the spray setup calls for, and a fine oil mist carried to keep the spray gun's air valve moving smoothly.
A bench of air-driven screwdrivers, riveters and clamps fed from a 1/4 in drop line uses this three-unit set to clean the air, set the working pressure on the psi gauge, and lubricate the tools through the day.
Carton formers, case sealers and labelling heads running on small cylinders benefit from filtered, regulated and lubricated air at the machine, with the reverse/check valve helping hold the circuit's state and the bracket giving a clean panel mount.
Start with size and port: the GC300 step covers 1/4 in PT piping here, and larger sizes (400, 600) carry larger ports and more flow capacity, so step up if your line demand is high. Choose the filter grade for the job: the standard 40 um element suits general plant air, while the 5 um element (this unit, code W) suits finer protection downstream of the filter. Pick the drain type where it applies: differential-pressure (this unit's default), automatic, or manual. Set the gauge to the scale your team reads - MPa, psi or bar - and note this unit is the low-pressure regulator type, so confirm the exact adjustment range with us before ordering. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options; a bracket is included, and a reverse/check valve is fitted on this code.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated number, so we do not quote a flow figure here. Send us your application details and we will confirm the sizing against the datasheet before you order.
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 rather than a single rated figure, so we do not quote a flow number. Tell us your application - line pressure, downstream consumption and port size - and we will confirm the flow and full datasheet figures for the GC300 on request before you order.
The W in the code GC30008LF2WK selects the 5 um filter element instead of the standard 40 um, which suits applications needing finer removal of particulate and water carryover. The F2 selects the embedded square gauge scaled in psi. Both are standard catalogue choices on the GC series - the 40 um element and MPa or bar gauge scales are available on other codes if your plant standard differs.
