The AirTAC GC30008LF2K AirTAC F.R.L. Combination, PT1/4, Low-Pressure 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 GC30008LF2K is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air from a single assembled set: a separate filter, a pressure regulator and an oil-mist lubricator. This 300-size unit is built with a PT1/4 (1/4 in) PT thread, the standard 40 um filter element for general-purpose water and particulate removal, and a differential-pressure drain on the filter bowl. It is a low-pressure type, and the fitted reverse/check valve holds downstream pressure if the upstream supply is interrupted. The embedded square gauge reads in psi, so the set pressure can be checked at a glance.
This is a genuine AirTAC part in the GC series, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and G (BSPP) or NPT threads as order options alongside the PT standard. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing for your application.

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.

Feeds spray guns on a finishing line with cleaned, pressure-stabilised and oil-misted air, so the gun atomisation stays consistent through a shift while the check valve holds the set pressure if the plant supply dips.
Supplies a small pneumatic press or clamping fixture where the regulator sets the working pressure for consistent forming force, the lubricator mists the cylinder seals, and the 40 um element keeps machining swarf and condensate out of the valve stack.
Conditions the air feeding carton-sealing and wrapping machinery, where the low-pressure regulator suits equipment that runs at reduced supply pressure and the differential-pressure drain clears accumulated water during continuous production runs.
Start with the port step: this unit is 300 size with a PT1/4 (1/4 in) PT thread, so match it to the line size and the air demand of the equipment it feeds - larger sizes (400, 600) carry bigger ports for higher demand, and G (BSPP) or NPT threads can be ordered instead of PT. The 40 um element is the standard grade for general plant air; if finer filtration is needed, the W-coded 5 um grade is available in the series. Drain choice matters: this unit uses the differential-pressure drain (the default), while automatic (A) and manual (M) drains are decodable options. The gauge here is the embedded square type reading psi; MPa or bar scales and an external round gauge are alternatives, and the fitted K-coded check valve is what sets this configuration apart from standard sets.
Because flow for the GC series is published only as curves and not as a single rated figure, and the exact regulation range of the low-pressure type is not published, ask us to confirm sizing and the regulator range 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 the GC series as performance curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your application and operating pressure and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks this as a low-pressure regulator type rather than the standard version; the exact regulation range for the low-pressure type is not published, so we confirm it on request. The trailing K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is cut. The F2 code is the embedded square gauge reading in psi.
