The AirTAC GC30008ALF2W 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 automatic 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, pressure regulator and lubricator assembled as one unit, so the compressed air is cleaned of water and particulate, held at the set pressure, and carries a fine oil mist before it reaches downstream cylinders, valves and tools. This GC30008ALF2W is built on the 300 size with PT1/4 (1/4 in) ports. The W code selects the optional 5 um filter element (finer than the 40 um standard), the A code fits an automatic drain that expels collected condensate from the filter bowl without manual attention, and the L code makes it a low-pressure type regulator - its exact adjustment range is not published, so confirm your set pressure with us. A square pressure gauge reading in psi is fitted, no reverse/check valve is included, and at this size the filter bowl is polycarbonate (PC).
This is a genuine AirTAC part. The GC family is offered in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread (PT standard, with G and NPT as catalogue options) and reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working 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 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 a spray booth's atomising circuit, the unit strips water and particles down to 5 um, holds the reduced pressure the low-pressure type regulator is chosen for, oils the line to the spray gun, and drains condensate automatically between shifts.
On an assembly cell running small pneumatic cylinders and grippers, this one 1/4-in drop filters, regulates and lubricates the air in a single GC unit, keeping valve and seal surfaces fed with oil mist over long production runs.
Driving carton closers, diverters and pushers on a packaging line, the combination keeps the 1/4-in air supply clean, regulated and oil-mist lubricated, with the square psi gauge giving operators a visible setpoint at the machine.
The real choices on this code: the 300 size with PT1/4 ports suits circuits plumbed at 1/4 in - step up to 400 or 600 as the circuit grows. The 5 um (W) element is the pick where finer filtration protects precision valves; the 40 um standard element suits general supply. The automatic drain removes condensate unattended - choose manual where you prefer operator-controlled draining. The low-pressure type regulator is selected for circuits needing lower regulated pressure; because its exact adjustment range is not published, tell us your set pressure and we will confirm suitability. The square gauge reads in psi, with MPa and bar scales available. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included. Flow is published as curves, not 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 the GC series as curves rather than a single rated figure, so we do not quote a number here. Send us your application's flow requirement and we will confirm the sizing against the datasheet curves before you order.
The W code selects the optional 5 um filter element instead of the 40 um standard, for finer protection of downstream valves and tools. The A code fits an automatic drain, so the filter bowl expels collected condensate on its own instead of relying on manual draining.
