The AirTAC GC40015MLF2GK AirTAC F.R.L. Combination, G1/2, Manual Drain 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC40015MLF2GK is a three-piece AirTAC GC-series F.R.L. combination that filters, regulates and lubricates compressed air in one assembled set: a separate filter, regulator and lubricator. This configuration is built in the 400 size with 1/2 in ports threaded G (BSPP). The filter element is the standard 40 um grade for water and particulate removal, with a manual drain on the PC (polycarbonate) bowl, so an operator drains accumulated condensate by hand. The regulator is the low-pressure type, and this unit carries an embedded square gauge scaled in psi. A reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, and gauge scales in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so 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. 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)). |

| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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-booth and paint-line drops in an automotive plant, where clean, moisture-reduced air protects finish quality and the lubricator keeps air tools running smoothly.
Conditions the supply to pneumatic cylinders and grippers on a carton-forming and wrapping conveyor line, with the 1/2 in ports serving the main drop feeding multiple stations.
Sits at the machine inlet of a CNC machining cell, filtering water and swarf-carrying particulate out of the shop air, holding a set pressure to the tool-change circuit and oil-mist lubricating the air motors.
Start with the size and port: the 400 size with 1/2 in ports sits in the middle of the GC range (200/300/400/600), and the right step depends on the air demand of the downstream circuit - move up a size if your flow requirement is near the top of a smaller unit's curve. Choose the drain to suit access: manual drain (this unit) suits attended installations, while automatic or differential-pressure drains suit unattended ones. Choose 40 um for general protection or the 5 um (W) element where finer filtration is needed. Pick the gauge scale - this unit is square, psi - and confirm the thread: PT is the standard, with G and NPT as order options (this unit is G).
One honest note before ordering: flow is published as curves, not a single rated number, so ask us to confirm sizing against your application and the datasheet before you commit. The low-pressure regulator's exact adjustment range is likewise confirmed on request.
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 this family as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and required air demand and we will confirm the flow figures from the datasheet on request before you order.
The M in the code sets a manual drain: an operator opens the drain on the polycarbonate filter bowl by hand to remove collected condensate, which suits installations that are checked regularly. The L sets the low-pressure regulator type; its exact adjustment range is not published in the catalogue data we hold, so we confirm it on request. Everything else decodes as: 400 size, 1/2 in G-threaded ports, 40 um standard filter element, embedded square gauge scaled in psi, a fitted reverse/check valve, and an included mounting bracket.
