The AirTAC GC400-15MLC2W AirTAC F.R.L. Combination, PT1/2 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 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC400-15MLC2W is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one compressed-air treatment set. This configuration is built on the size 400 body with PT1/2 (1/2 in) PT threaded ports, carries the W fine-filtration element rated at 5 um for tighter water and particulate removal than the standard 40 um element, and uses a manual drain on the filter bowl, so an operator opens the drain valve periodically to discharge collected condensate. The regulator is the low-pressure type and a round gauge graduated in psi is fitted, giving a direct pressure readout at the setpoint. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options include drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um), gauge style and scale (MPa, psi or bar), reverse/check valve and G or NPT thread variants. Flow is published as curves rather than a single rated figure, so ask us to 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. 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.

|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

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: GF400-15 filter, GR400-15 regulator and GL400-15 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.

Feeds filtered, regulated and lubricated air to spray guns and air-assisted applicators on a paint line, where the 5 um element helps keep water and particulates out of the finish and the lubricator mists the gun's air motor.
Conditions the shop-air feed to a machining centre's pneumatic tool changer, clamps and coolant spray nozzles, with the low-pressure regulator holding a stable supply pressure and the psi gauge giving operators a visible setpoint.
Serves the cylinder and valve manifold supply on a carton-forming and case-sealing conveyor line, where one PT1/2 F.R.L. set treats the whole branch circuit and the manual drain suits a shift-based maintenance routine.
Size 400 with PT1/2 ports sits in the upper-middle of the GC range; step up to size 600 or down to size 300 depending on the flow your line needs - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit is already specified with the choices that matter: 5 um fine filtration (the 40 um standard element is the alternative if your air quality target allows it), a manual drain (simplest and lowest cost, but it needs periodic operator attention - automatic or differential-pressure drains suit unattended installations), the low-pressure regulator type, and a round psi gauge. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A mounting bracket is included.
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 GR400-15 regulator with a GF400-15 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 application and line pressure and we will confirm the flow figures from the datasheet on request before you order.
The M in the code GC400-15MLC2W selects the manual drain: an operator opens the drain valve periodically to discharge condensate from the filter bowl. If the installation runs unattended, the GC series is also available with automatic (A) or differential-pressure (blank) drains - ask us for those variants.
