AirTAC GC400-10 FRL Unit (GC40010LN)
The AirTAC AirTAC GC400-10 FRL Unit (GC40010LN) 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC400-10 FRL Unit (GC40010LN)
The AirTAC GC series combines a separate air filter, pressure regulator and lubricator as a three-unit F.R.L. set, so one supply line is filtered, regulated and oiled in the correct order. This GC40010LN is the 400 size with 3/8in PT ports, the standard 40 um filter element, a differential-pressure drain and a low-pressure type regulator, supplied without a gauge (N) for panels that carry their own instrumentation. Like every GC set it runs on compressed air only, accepts up to 1.0 MPa (145 psi) inlet, works from -5 to 70 C (non-freezing), and uses polycarbonate bowls at this size.
It is a genuine AirTAC part from the G-series air-treatment range, which spans sizes 200, 300, 400 and 600 with ports from 1/8in to 1in, plus options such as automatic or manual drains, a finer 5 um element, G (BSPP) or NPT threads, and gauged versions with MPa, psi or bar scales. Flow for the series is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet values for this exact model against 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. 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.
Model Code: AirTAC GC400-10 FRL Unit (GC40010LN)
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
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.

Where the AirTAC GC400-10 FRL Unit (GC40010LN) Is Used
Warehouse sorter diverter cylinders
Conditions air for the diverter and pusher cylinders on a distribution-centre sorting conveyor; with no gauge fitted, it suits lines where pressure is monitored at a central panel.
Carton erector on a packing line
Runs the flap-fold and clamp cylinders of a carton erector on a food packing line, filtering and lubricating the shop air before it reaches the small cylinders.
Bus assembly air-tool lines
Supplies regulated, lubricated air to ratchet and impact tool stations on a bus assembly line, where the crew relies on the workshop panel gauge rather than a gauge at each set.
Is the AirTAC GC400-10 FRL Unit (GC40010LN) the Right Station?
Use the 400 size when your line port is 3/8in and demand sits above what a 300 set comfortably serves; larger sizes move more air, and because the figures are curve-based we will verify the sizing against your demand before you order. The differential-pressure drain suits a steadily used line, with automatic or manual drains as alternatives in the series. This N version omits the gauge, which suits central panels or circuits with their own instrumentation; gauged versions with square or round dials on MPa, psi or bar scales are available. G (BSPP) or NPT threads can be ordered in place of the PT standard.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
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 GC400-10 FRL Unit (GC40010LN) FAQ
AirTAC publishes flow for the G series as performance curves, not as a single rated number, so we do not state a figure here. Send us your required flow and inlet pressure and we will confirm the GC40010 datasheet curve against your application before you order.
Yes. The N suffix means this version is supplied without a gauge. Gauged versions of the same 400 size, 3/8in set are available with a square or round dial on MPa, psi or bar scales, so you can match the readout to the rest of your panel.
