The AirTAC GC30008LF2GK AirTAC F.R.L. Combination, G1/4 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 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one complete air-preparation set. This configuration, GC30008LF2GK, is the size 300 unit with a G1/4 (BSPP) port. The filter element is the standard 40 um grade with a differential-pressure drain, the regulator is the low-pressure type fitted with an embedded square gauge scaled in psi, a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port options, drain types, filter grades, gauge scales and thread variants to order. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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.

|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Feeding impact wrenches and nutrunners on a vehicle assembly line: the set filters line water and particles, holds a steady low working pressure at the tool, and carries oil mist into the tool for lubrication.
Supplying cylinders and pneumatic grippers on a carton-forming and sealing machine, where clean, regulated and lubricated air keeps repetitive clamping motions consistent through long production runs.
Preparing air for looms and spinning frames, where jets and actuated guides need filtered, pressure-stabilised and lubricated air to prevent sticking and premature wear of moving parts.
Start with the size and port: this is the size 300 set with a G1/4 port, one step up from the 200 series, and the right choice depends on the flow your line needs - we can check the published flow curves against your demand. The differential-pressure drain on the filter bowl purges automatically as the pressure differential rises, with no operator input. The 40 um element is the standard grade; a 5 um element (code W) is available if finer filtration is needed. The low-pressure regulator suits circuits that run below standard line pressures - confirm the exact adjustment range with us, as it is not published in the standard table. The square gauge is scaled in psi; MPa and bar scales are alternatives. Thread is G (BSPP) here, with PT and NPT variants orderable. Ask us to confirm sizing against the 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 the GC series as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing against the datasheet curves on request before you order.
The L in the code marks the low-pressure regulator variant, intended for circuits that run below standard line pressures; the exact adjustment range for this variant is not published in the standard table, so confirm it with us. The K code means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is interrupted.
