The AirTAC AirTAC GC300-10 FRL Unit (GC30010C1W) 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 PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator arranged as one set, so the line is filtered, regulated and oiled in that order. This GC30010C1W is the size 300 set with PT 3/8 inch ports, a fine 5 um filter element, differential-pressure drain on the filter bowl, a standard regulator and a round pressure gauge reading in MPa. In service the filter removes water and particulate, the regulator holds your set pressure across its 0.15-0.9 MPa (20-130 psi) adjustment range, and the lubricator meters oil mist downstream to air tools and cylinders. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing; the filter and lubricator bowls at size 300 are polycarbonate.
This is a genuine AirTAC part. The G-series air-treatment range runs from size 200 to 600 with ports from 1/8 to 1 inch, G(BSPP) and NPT thread variants, and a choice of drain types, filter grades, gauge scales and check valves. Flow data is published as curves rather than a single rating, so contact us and we will confirm sizing and 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: GF300-10 filter, GR300-10 regulator and GL300-10 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.

Mounted at the drop of a machining centre's pneumatic pallet-clamp circuit, this FRL set strips water from the shop air, holds a stable clamp pressure and oils the clamp cylinder so the drawbar keeps seating tools consistently shift after shift.
Feeding the pneumatic valves and flap-fold cylinders of an end-of-line carton sealer, the 5 um element keeps condensate and fines out of the sealing heads while the regulator pins the actuation pressure for repeatable box clamping.
Installed ahead of the tool drops in an automotive assembly cell, the set delivers filtered, regulated and lubricated air to impact drivers and nutrunners, keeping their vane motors lubricated through a full production day.
Size 300 with 3/8 inch ports is the mid-range step in the G-series ladder (200, 300, 400, 600); the right size depends on the air demand of the line, so treat the port as the plumbing match and confirm the flow against your consumption. Drain type matters on the filter bowl: this unit uses the differential-pressure drain (opens as the bowl fills), with automatic (A) and manual (M) variants orderable in the same family. The W code selects the 5 um element; the standard grade is 40 um if your application tolerates coarser filtration. The C1 code fits the external round gauge with an MPa scale - psi (C2) and bar (C3) scales are available on the same size. PT thread is standard; G(BSPP) and NPT versions are catalogue options to order. A mounting bracket is optional.
Flow for the GC300 is published as curves, not a single rated figure, so 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC300 as characteristic curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your line pressure and air consumption and we will confirm the sizing from the datasheet on request before you order.
The blank filter grade on GC sets is 40 um, which suits general plant air. The W code specifies the finer 5 um element for applications where dirt and condensate carryover into valves and cylinders must be minimised. Both grades fit the same size 300 filter bowl, so the choice is purely about air quality, not plumbing.
