The AirTAC GC400-15 AirTAC F.R.L. Combination, PT1/2, 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 GC400-15 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 400-size unit. This configuration has PT1/2 ports, a 40 um filter element, a manual drain on the filter bowl, and a standard regulator whose setting range is 0.05-0.9 MPa (7-130 psi). The embedded square gauge is fitted with a psi scale, and a mounting bracket is included. The filter bowl on this 400 size is PC (polycarbonate).
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with a choice of ports, manual or automatic drain, a 5 um element option, gauge scale, and G or NPT thread variants. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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 0.05 - 0.9 MPa (7 - 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: GF400-15 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 clean, regulated and lubricated air to a machining centre's tool-change and clamping circuits, with the 40 um element and manual drain suiting a cell visited on every shift.
Serves point-of-use drops on an assembly line where pneumatic impact tools and air cylinders need filtered, pressure-regulated, oil-misted air at a set psi.
Supplies the actuator circuits of case packers and palletisers, keeping water and particles out of valves while the lubricator mists oil for cylinder and tool longevity.
Start with the size and port: 400-size units step up from 300 in both port size and flow capacity, so match the 1/2 in PT port to your supply line and the flow curve to your demand. Choose the drain next: this unit has a manual drain, which suits positions someone can reach on a routine; automatic drain is the option where the unit sits in an inaccessible spot. Filter grade is 40 um as standard here, with 5 um (code W) available when finer particle removal is needed. The fitted square gauge reads in psi; MPa and bar scales are also offered. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, so please 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for this family as curves rather than a single rated figure, so there is no one number we can quote. Tell us your line pressure and air demand and we will confirm the flow from the datasheet for this 400-size, PT1/2 unit before you order.
The filter bowl on this GC400-15 has a manual drain: collected water is released by hand at each service visit. It suits positions reached on a routine. If the unit will sit where nobody passes regularly, ask about the automatic-drain variant instead.
