The AirTAC GC400C15MLF2G AirTAC F.R.L. Combination 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15MLF2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one complete air-treatment set. This size 400 unit is built with a 1/2 inch G (BSPP) port. The filter section carries the standard 40 um element with a manual drain, so accumulated water is released by operating the drain by hand. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi; no reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600, with port sizes stepping up accordingly, and with options such as drain type, 5 um filtration (code W), gauge scale and thread form (PT standard, G and NPT to order). Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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. 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: GF400-C1 filter, GR400-C1 regulator and GL400-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.

At each assembly station, the combination cleans shop air of water and particulate, holds the supply at the set pressure for air tools, and carries oil mist downstream to keep impact wrenches and ratchets lubricated through the shift.
Carton sealers and wrapping machines run cylinders and sealing actuators continuously; this unit supplies them with filtered, regulated and lubricated air from a single 1/2 inch connection, with the square psi gauge giving operators a visible setpoint.
Pneumatic clamps on machine-tool fixtures depend on steady, clean supply air; the filter protects the valve stack, the low-pressure regulator holds the clamping circuit at its set pressure, and the lubricator conditions air for the cylinder seals.
Start with the port step: size 400 in this series serves 1/2 inch piping, and moving up or down a size changes both the port and the flow capacity, so match the size to the air demand of the circuit rather than to the pipe alone. On the filter section, choose the drain type deliberately: manual drain (this unit) means an operator drains the bowl, while automatic and differential-pressure drains handle it without attention; choose the standard 40 um element for general protection, or the 5 um W option where finer filtration is needed. On the regulator, this code specifies the low-pressure type with an embedded square gauge scaled in psi; MPa and bar scales and an external round gauge are the other gauge choices. Thread is G (BSPP) here, with PT as the standard alternative and NPT available to order.
Because flow is published as curves rather than a single rated figure, we do not quote one number here. Send us your application details and we will confirm sizing against the datasheet before you order.
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 GR400-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for this series as characteristic curves rather than a single rated figure, so we do not quote one number on the page. Tell us your application and line pressure and we will confirm the flow and sizing against the datasheet on request.
The L in the code marks the regulator as the low-pressure type rather than the standard type; the exact adjustment range for this variant is not published in the sheet we use, so we confirm it on request. The M marks a manual drain on the filter bowl: water collected from the compressed air is released by operating the drain by hand, instead of automatically as with the A (automatic) or differential-pressure drain options.
