The AirTAC GC300C10MLF2 AirTAC F.R.L. Combination, PT3/8 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-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled into one supply unit. This GC300C10MLF2 is built in size 300 with a PT3/8 port. The filter element is the standard 40 um grade and the bowl is drained by hand (manual drain, code M). The regulator is the low-pressure type, and an embedded square gauge on a psi scale is fitted so downstream pressure can be read and set directly. A mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include automatic or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Rated flow for this series is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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.

Conditioning the shop-air feed to a CNC machining centre: the filter stage strips water and 40 um particulate, the regulator holds a steady set pressure read on the square psi gauge, and the lubricator delivers an oil mist to cylinders and air tools on the machine.
Supplying treated air to the cylinders, grippers and diverters on a carton-sealing or palletising conveyor, keeping downstream pressure stable while the lubricator helps extend seal and valve life across a long production shift.
Feeding impact wrenches, grinders and riveters at a maintenance or assembly bench: one unit filters the supply, holds the set pressure on the square psi gauge and carries oil mist to the tools, with the manual drain emptied as part of daily checks.
Choose the size and port against the air consumption of the downstream circuit: this unit is size 300 with a PT3/8 port, and the GC family steps through sizes 200, 300, 400 and 600 with larger ports and greater capacity. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. Other decodable choices: drain type (manual here; automatic or differential-pressure are the alternatives), filter grade (40 um standard, 5 um with code W), gauge scale (psi here; MPa or bar available), thread (PT standard; G or NPT to order), and the low-pressure regulator type fitted on this model - its exact adjustment range is not published, so confirm it with us.
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 flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Send us your air consumption and working pressure and we will confirm the datasheet curve and check the sizing for your application before you order.
The M in the code sets a manual drain: the filter bowl is emptied by hand, unlike the automatic (A) or differential-pressure (blank) options. The L sets the low-pressure regulator type; its exact adjustment range is not published in our data, so confirm it with us. The square gauge fitted on this unit reads in psi, and MPa or bar scales are available.
