The AirTAC GC300C10MLC2 AirTAC F.R.L. Unit 3/8 in PT, Low-Pressure Type 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 GC300C10MLC2 is a three-piece AirTAC GC series F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator piped together as one air-preparation set. This configuration is built for a 3/8 in PT port, carries a manual drain on the filter bowl, a 40 um standard filter element and a low-pressure type regulator. The round pressure gauge fitted to this code reads in psi, and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing); the filter bowl on this 300 size is PC (polycarbonate).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard, G and NPT to order), drain types, filter grades and gauge styles, so a matching set can be built for most compressed-air lines. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and flow 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 0.15 - 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.

Feeding filtered, regulated and lubricated air to the clamps and pneumatic fixtures on a CNC milling or turning cell, where chips and condensed water in the shop-air supply must be removed before they reach the fixture cylinders.
Supplying prepared air to the cylinders and vacuum generators on a carton-sealing or case-erecting conveyor line, with the lubricator keeping seal and flap cylinders running smoothly through long production shifts.
Conditioning the air feeding spray guns in a paint or coating booth, where water and particulate must be stripped out and pressure held steady at the gun, with oil mist dosed where the gun manufacturer calls for it.
Start with the size and port: this unit steps up to the 300 frame with a 3/8 in PT port, and larger sizes carry larger ports and more flow capacity, so match the frame to the air demand of the line. The manual drain on this code means an operator opens the drain at intervals; if unattended draining is preferred, differential-pressure or automatic drain variants exist in the family. The 40 um element is the standard grade; a 5 um element (code W) is available where finer filtration is needed. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included. Note that this is the low-pressure type regulator; its exact adjustment range is not published in the material we hold, so ask us to confirm it. Because flow is published as curves rather than a single rating, 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 flow for the GC series as curves, not as a single rated figure, so we do not quote a flow number. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing against the datasheet curves on request.
The L code in GC300C10MLC2 marks the low-pressure type regulator rather than the standard one. Its exact adjustment range is not published in the material we hold, so ask us to confirm the range before ordering if your process runs at low regulated pressures.
