The AirTAC GC300-08 AirTAC F.R.L. 3-Piece Unit, PT1/4 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This GC300-08 is the 300 size with 1/4 in PT ports. The filter carries the standard 40 um element with a manual drain, the standard-type regulator adjusts from 0.05 to 0.9 MPa (7-130 psi) and is fitted with a round gauge reading in psi, and the lubricator feeds oil mist to downstream equipment. A reverse (check) valve is fitted (code K) and a mounting bracket is included. Bowls on the 300 size are polycarbonate (PC). Max inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic or differential-pressure drains, a 5 um filter element (code W), the embedded square gauge with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of PT. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application on request.

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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

Filtered, regulated and lubricated air for impact wrenches and pneumatic drivers at a vehicle assembly station, with the reverse valve fitted in the circuit and the round psi gauge giving operators a local setpoint readout.
Air preparation for cylinders and grippers on a bottling or cartoning conveyor line fed from a 1/4 in drop: the 40 um element strips water and swarf, the regulator holds the working pressure and the lubricator mists the valve seals.
A supply point for nailers, spray guns and air tools in a joinery workshop, where the lubricator carries oil mist to tool motors and the manual-drain PC bowl is emptied during end-of-shift checks.
Size and port are the first choice: 200, 300, 400 and 600 step up in port and flow capacity, and this unit's 1/4 in PT port must match your supply line. Drain type is decodable: manual (this code, M), automatic (A) or differential-pressure (blank); a manual drain needs periodic operator attention, while the other types discharge condensate without it. Filter grade is 40 um standard or 5 um with W. Gauge choices are the embedded square type or an external round gauge, with MPa, psi or bar scales. Threads are PT as standard with G (BSPP) and NPT as orderable options, and a bracket is included. Flow is published as curves, not a single rating, 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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow and sizing for the 300 size at your working pressure before you order.
The M in GC30008MC2K sets a manual drain on the filter bowl: condensate collects in the PC bowl and an operator opens the drain periodically. If you prefer unattended discharge, the same size is available with an automatic (A) or differential-pressure (blank) drain - ask us and we will confirm the variant against the datasheet.
