The AirTAC GC30008ALF2GK AirTAC F.R.L. Combination G1/4 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008ALF2GK is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one treatment set for compressed-air circuits on a G1/4 (BSPP) port. In this configuration the filter carries the standard 40 um element with an automatic drain that ejects collected condensate without manual attention, the regulator is the low-pressure type for circuits that run below standard supply pressure, and the embedded square gauge reads in psi so operators can set and monitor downstream pressure at a glance. A reverse/check valve is fitted, and the mounting bracket is included for panel or frame installation. The filter and lubricator bowls are PC (polycarbonate).
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options including manual or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Max working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Rated flow is published as curves rather than a single 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. 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.

Feeding the pneumatic cylinders on a carton-forming and sealing conveyor: the filter strips water and 40 um particulate, the low-pressure regulator holds a steady downstream setting for gentle clamp-and-push motion, and the lubricator mists oil to keep cylinder seals and bore surfaces working smoothly.
A point-of-use set at an assembly bench where impact drivers, ratchets and air screwdrivers are run all shift: clean, regulated and lubricated air at the tool drop, with the psi gauge letting each station set its own downstream pressure and the automatic drain keeping the bowl clear without daily attention.
Supplying pneumatic clamps and workholding actuators on a CNC cell: the regulator holds a stable clamping pressure readable on the square psi gauge, the reverse/check valve helps hold the downstream side, and the filter and lubricator protect the clamping cylinders from contamination and wear.
Start with the size and port: this unit is size 300 on a G1/4 (BSPP) port, one step up from 1/8 in and one step down from 3/8 in - match the port to your line and let the required air demand drive whether 300 is the right size step. The automatic drain on the filter is the low-maintenance choice for unattended or hard-to-reach installations; manual and differential-pressure drain versions exist if you prefer hands-on control or a drain that responds to pressure drop. The 40 um element is the standard grade for general plant air; the 5 um (W) element is the option where finer particulate removal matters. The gauge here is the embedded square type reading psi; MPa and bar scales are available, as is an external round gauge. The thread is G (BSPP) in this code - PT is the catalogue standard, with G and NPT as order options - and the bracket is included. Note that the regulator is the low-pressure type; its exact adjustment range is not published in the material we hold, so confirm it with us. 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 a l/min or SCFM number. Send us your application details - line pressure, downstream demand and duty - and we will confirm the flow curve from the datasheet and check the size 300 / G1/4 combination against your requirement before you order.
The L code in GC30008ALF2GK marks the regulator as the low-pressure type, intended for circuits that run below standard supply pressure rather than at the full adjustment span of the standard version. Its exact adjustment range is not published in the material we hold, so confirm the range with us against your set pressure before ordering. Max inlet pressure is still 1.0 MPa (145 psi).
