About the AirTAC GC400-15 FRL Unit (GC40015C1)
The GC40015C1 is a genuine AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied as one set. It is size 400 with a 1/2 in. PT (standard) port, fitted with the standard 40 um filter element, a differential-pressure drain that bleeds condensate as flow passes the bowl, and an external round gauge reading in MPa so operators can set and monitor the regulated pressure at a glance. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with this drain type, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the G-series range, which covers sizes 200, 300, 400 and 600 with port and thread options including PT, G (BSPP) and NPT. On this size 400 unit the filter bowl is polycarbonate, and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm datasheet and sizing 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 0.15 - 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 GC400-15 FRL Unit (GC40015C1) Is Used
Packaging machine valve island supply
Conditioning the air feeding a directional-valve manifold on a carton-forming and sealing machine, with the MPa gauge letting technicians verify set pressure at the machine during changeover.
Pneumatic press shop air drop
Filtering, regulating and lubricating the supply to a small pneumatic assembly press, where the 40 um element handles general shop air and the gauge gives the operator a visible setpoint.
Textile machine cylinder circuits
Supplying cleaned, regulated and lubricated air to the thread-tension and doffer cylinders of textile machinery, with the differential-pressure drain keeping the bowl clear during continuous running.
Is the AirTAC GC400-15 FRL Unit (GC40015C1) the Right Station?
Step up to size 400 with the 1/2 in. PT port when your demand sits between the 3/8 in. size 300 and the 3/4 in. size 600. The default 40 um element is the right grade for general machine air; choose the 5 um (W) version of this code when finer protection is needed. The differential-pressure drain is the zero-maintenance default, while automatic (A) and manual (M) drain variants of the same set are available.
The C1 code selects the external round gauge with an MPa scale; psi and bar scale gauges are offered in the series. Thread is PT as standard, with G and NPT as catalogue options. AirTAC publishes flow only as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015C1) FAQ
Flow for the GC400 size is published by AirTAC as curves, not as a single rated number, so we do not state a figure here. Send us your working pressure and required air consumption and we will confirm the correct size from the datasheet on request.
Functionally the GC combination provides the same filtration, regulation and lubrication, but it arrives as a matched three-piece set with consistent porting, so installation is simpler. You still choose the decodable options - drain type, 40 um or 5 um element, gauge style and scale, and PT, G or NPT thread - within the series.
