The AirTAC GC30015LC2GK AirTAC F.R.L. 3-Unit, G1/2, Low-Pressure 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 PT1/2" 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-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one supply unit. This GC300 configuration is built for 1/2 in (G1/2) lines and pairs 40 um filtration with a low-pressure regulator, a round psi gauge, a reverse/check valve and an included mounting bracket. The filter bowl drains by differential pressure, so it bleeds accumulated condensate as the pressure differential across the element builds, with no daily manual draining routine.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, G (BSPP) or NPT threads on order, manual or automatic drain variants, a 5 um filter grade (code W) and gauge scales in MPa, psi or bar. Flow figures for this series 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: GF300-15 filter, GR300-15 regulator and GL300-15 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.

Installed at the take-off point of a factory compressed-air ring main, it cleans water and particulate from the 1/2 in branch, holds a steady low working pressure for downstream tools and meters oil mist into the line.
Feeding cylinders and air grippers on a packaging or conveyor line, the combination keeps moisture out of the valve island, regulates supply to the actuators and lubricates the moving seals for everyday running.
Mounted on the cabinet of a machine tool or CNC cell, it conditions the shop-air feed to sensitive pneumatic circuits: filtered to 40 um, regulated at a low set point with a psi gauge visible to the operator, and lubricated via the oil-mist unit.
Start with the port step: this unit is the 300 size with a 1/2 in G-threaded port, so match it to the air line it feeds; larger sizes carry larger ports and more flow capacity. Because flow is published as curves rather than one rated figure, send us your application's air demand and we will confirm sizing against the datasheet before you order. Other decodable choices in the family: drain type (differential-pressure as fitted here, or automatic code A, or manual code M), filter grade (40 um standard, 5 um with code W), gauge scale (MPa, psi or bar - this unit reads psi on a round external gauge), thread (PT is the standard; G and NPT are order options) and the bracket, which is included on this configuration. As a low-pressure type (code L), the regulator is intended for lower set-point work; its exact adjustment range is not published, so confirm it with us for your set pressure.
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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your line size and air demand and we will confirm the flow from the datasheet and check the sizing against your application before you order.
This unit's filter bowl uses a differential-pressure drain: condensate is discharged automatically as the pressure drop across the filter element builds, so there is no routine manual draining. If you prefer a manual drain (code M) or a fully automatic drain (code A), those variants exist in the GC family - ask us for the matching model.
