The AirTAC GC FRL Unit GC300C15MC1W 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator delivered as one set. This GC300C15MC1W is built in size 300 with 1/2 in PT ports, a manual drain on the filter bowl, the optional 5 um (W) filter element and an external round pressure gauge with MPa scale. It strips water and fine particulate from compressed air, holds a set downstream pressure and meters oil mist into the line.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, with differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) element, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. 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 rating; ask us and we will confirm the datasheet figures 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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-C1 filter, GR300-C1 regulator and GL300-C1 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.

Supply pneumatic controls on a laboratory analyzer or pilot-plant skid. The 5 um element protects sensitive pilot valves, transducers and gauges from fine particulate while the regulator holds the set supply pressure and the lubricator conditions actuator air.
Feed the clamping circuits of a machining fixture where fine particles could upset small pilot valves. The 5 um element cleans the supply, the regulator holds the clamp pressure and the manual drain lets operators purge the bowl each shift.
Run the cylinder and valve circuits on a printing press. The W-grade element filters the shop air more finely before it reaches the register and impression controls, while the regulator and lubricator condition the supply to the press.
Size 300 with 1/2 in PT ports sits mid-range in the GC series; step up to 400 or 600, or down to 200, with the matching port if your line demands it. The W suffix specifies the 5 um element instead of the 40 um standard, for finer particulate protection; water removal is still the job of the filter bowl with its manual drain. The manual drain widens the regulator adjustment range to 0.05-0.9 MPa (7-130 psi); automatic and differential-pressure drain versions adjust between 0.15-0.9 MPa (20-130 psi). The C1 suffix specifies an external round gauge on MPa scale. PT is the standard thread, with G (BSPP) and NPT as order options. Because flow is published as curves rather than a single rated figure, 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes GC series flow data as performance curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the datasheet curve for this size 300, 1/2 in unit against your application before you order.
The standard 40 um element suits general plant air; this W version carries the optional 5 um element for finer protection of pilot valves, instrumentation and air tools. Note the grade concerns particulate only: water is still removed by the filter bowl, which here is drained manually.
