The AirTAC GC400-10 AirTAC F.R.L. Combination, G3/8" 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 PT3/8" ports, a 40 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The GC400-10 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set, giving a compressed-air line filtration of water and particulate, downstream pressure regulation and lubrication in a single installation. This configuration is built around a 3/8 in port with G (BSPP) thread, a manual drain on the filter bowl, the standard 40 um filter element, an embedded square pressure gauge reading in psi, the standard regulator type, and a mounting bracket included. The maximum working (inlet) pressure is 1.0 MPa (145 psi), the regulator adjustment range is 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a matching step up in port size, and can be ordered with automatic, manual or differential-pressure draining, a 5 um filter element (code W), alternative gauge scales (MPa, psi or bar), and PT, G or NPT thread as order options. Flow is published by AirTAC 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. 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: GF400-10 filter, GR400-10 regulator and GL400-10 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.

On a production assembly bench running air impact drivers, nutrunners and clamping fixtures, the GC400-10 cleans the shop supply, holds a set working pressure at the bench and meters oil mist to keep air tools lubricated through a full shift.
At a spray-finishing booth, the combination filters water and pipe scale out of the air before the gun, regulates a stable atomising pressure, and feeds a light oil mist to the air motor and trigger valve of the spray equipment.
On a cartoning or case-packing line with cylinders, vacuum generators and air-actuated sealers, the GC400-10 conditions the machine's air supply: filtered and drained, regulated to the machine's set pressure, and lubricated for long cylinder and valve life.
Start with the size and port: the 400 size steps up in port and flow capacity from the 200 and 300 sizes, so match the 3/8 in G-thread connection to your supply line and the air demand of the equipment downstream - ask us to confirm sizing against the published flow curves before ordering. Choose the drain type for the filter bowl: this unit has a manual drain, which suits attended installations where an operator bleeds the bowl on a routine; automatic or differential-pressure draining is available if the unit will be left unattended. The standard element is 40 um; select the 5 um option (code W) where finer particulate removal is needed. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are options. Thread is G (BSPP) on this unit, with PT and NPT available as order options, and 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure for this unit. Send us your line size and the air demand of your equipment and we will confirm the sizing from the datasheet flow curves on request before you order.
This GC400-10 is ordered with a manual drain on the filter bowl, meaning the collected condensate is bled off by hand as part of routine maintenance. If the unit will be installed where nobody drains it regularly, the GC series can be ordered instead with an automatic or differential-pressure drain - just ask when ordering.
