The AirTAC GC30008LF2WG AirTAC F.R.L. Combination, G1/4, 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This configuration, GC30008LF2WG, is the size 300 unit with a 1/4 in port in G (BSPP) thread. The filter element is the 5 um grade (the W option, versus the 40 um standard) with a differential-pressure drain that bleeds collected water automatically as flow passes through. The regulator is the low-pressure type, fitted with an embedded square gauge reading in psi. The lubricator meters oil mist into the downstream air for pneumatic tools and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Bowls on the size 300 filter and lubricator are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filtration, standard or low-pressure regulation, and MPa, psi or bar gauge scales. Flow figures are published as curves rather than a single rating, 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.

At the spray booth, the 5 um element strips water and fine particulate before the regulator holds a steady low supply pressure to the gun, while the lubricator is left valved off or used for air tools at the same station.
On a carton-forming and sealing line, the combination conditions the air feeding the sealing and clamp cylinders: clean 5 um air, a stable low regulated pressure for consistent stroke force, and oil mist for the actuators.
At a bench assembly cell running impact drivers and nutrunners, the filter-regulator pair delivers clean, correctly set low pressure while the lubricator keeps the tool motors oiled through a shared 1/4 in drop.
Start with the port and size step: this unit is size 300 with a 1/4 in port, and the step up to size 400 or 600 gives larger ports and more flow capacity - match the step to your line's air demand. The drain on this configuration is differential-pressure (the default); automatic (code A) and manual (code M) drains are available if your duty needs them. Filtration here is the finer 5 um element; the 40 um standard grade suits general protection where finer conditioning is not required. The gauge is the embedded square type with a psi scale; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this code, with PT standard and NPT orderable - pick the one that matches your piping. A mounting bracket is included. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm 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 the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line's air demand and pressure and we will confirm the right size from the datasheet on request before you order.
The W in the code selects the finer 5 um element instead of the 40 um standard, for applications that need cleaner air. The L selects the low-pressure regulator type; its exact adjustment range is not published in our data, so ask us to confirm it against the datasheet for your set pressure.
