About the AirTAC GC400-10 FRL Unit (GC40010AC3)
The AirTAC GC40010AC3 is a genuine AirTAC three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator piped as one set for compressed air. This size 400 configuration carries a 3/8 in PT port, a 40 um standard filter element with an automatic drain in the filter bowl, and a round external gauge reading in bar on the regulator. The regulator adjusts between 0.15 and 0.9 MPa (20-130 psi) with this automatic-drain setup, and the set accepts a maximum working pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). The PC (polycarbonate) bowls suit the 400 size; only the 600 size uses aluminium alloy bowls.
This is a catalogue AirTAC part within the G series, which spans sizes 200, 300, 400 and 600 with larger ports and flow as the size number rises, plus options such as manual or differential-pressure drains, a 5 um filter element (W), PT/G/NPT threads and gauge choices. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm flow and datasheet figures 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 0.15 - 0.9 MPa (20 - 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.
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 (GC40010AC3) Is Used
Stamping press air preparation
A mechanical stamping press shop feeds its clutch, counterbalance and part-ejection circuits through this set: the filter removes water and 40 um particulate from the shop air, the regulator holds a steady working pressure, and the lubricator carries a controlled oil mist to the press air cylinders.
Bottling line conveyor actuation
On a beverage bottling line, pusher and gating cylinders on the conveyor transfer section run from this F.R.L. set. The automatic drain handles condensate from a humid fill-room environment while the bar-scale round gauge lets technicians set and verify line pressure at a glance.
Truck assembly cell tooling
At a commercial vehicle assembly cell, impact wrenches and clamp fixtures supplied from this set get filtered, regulated and lubricated air. The 3/8 in PT port serves the cell drop, and the automatic drain keeps the bowl clear across multi-shift production.
Is the AirTAC GC400-10 FRL Unit (GC40010AC3) the Right Station?
Size 400 with a 3/8 in PT port sits in the upper-middle of the G range; if your line demand approaches the top of what a 3/8 in port can serve, stepping up to 600 (1/2 in) gives more flow. The automatic drain here empties the filter bowl without daily attention - choose manual drain only where an operator is on site, or differential-pressure drain as the default. The 40 um element is the standard grade; specify the W variant for 5 um filtration downstream of sensitive valves. This set carries a round bar-scale gauge; an embedded square gauge is the other option, with MPa, psi or bar scales. Thread is PT as standard, with G (BSPP) and NPT available as catalogue options.
Flow for the GC400 series is published as curves, not a single rated number, so please ask us to confirm sizing against your application before ordering.
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 (GC40010AC3) FAQ
AirTAC does not publish a single rated flow figure for the GC400 series; flow is given as performance curves instead. We do not quote a made-up number, so please ask us and we will confirm the relevant flow and datasheet figures for your application on request.
The A in the code sets the automatic drain, so the filter bowl ejects condensate on its own, and the regulator range for this drain type is 0.15-0.9 MPa (20-130 psi). C3 selects the external round gauge with a bar scale; if you would rather have the embedded square gauge, or MPa or psi scales, those are catalogue options in the same series.
