About the Airtac GC FRL Unit GC400C15F1
GC400C15F1 is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator set that removes water and particulate, regulates pressure and meters oil mist into the compressed air line. It is sized 400 with PT1/2 (PT thread) ports, uses the standard 40 um filter element and the default differential-pressure drain on the PC (polycarbonate) bowls, and the F1 suffix specifies the square pressure gauge with MPa scale on the regulator.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with matching ports, with drain options of differential-pressure, automatic or manual, filter grades of 40 um standard or 5 um (W), round or square gauges in MPa, psi or bar scales, and G (BSPP) or NPT thread options to order. Maximum inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so we confirm the datasheet numbers 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-C1 filter, GR400-C1 regulator and GL400-C1 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 GC FRL Unit GC400C15F1 Is Used
Robotic welding cell services
Conditions the compressed air feeding a robot welding cell's torch-cleaning station, clamp actuators and positioner brakes, giving the cell one filtered, regulated and lubricated take-off point from the plant ring main.
Maintenance workshop bench supply
Mounted at a maintenance workshop air bench, it feeds impact wrenches, ratchets and blow guns from one point, with the square MPa gauge giving the technician a clear pressure readout and the lubricator keeping air tools oiled.
Plant air header drop lines
Installed on individual drop lines off a factory air header, so each machine or zone receives independently filtered, regulated and lubricated air instead of sharing one central setting.
Is the Airtac GC FRL Unit GC400C15F1 the Right Station?
Choose the size step first: the 400 body with PT1/2 ports sits between the 300 and 600 sets, and the right step depends on the air your circuit consumes. Keeping the differential-pressure drain gives a 0.15-0.9 MPa (20-130 psi) regulator range; the manual-drain variant allows 0.05-0.9 MPa (7-130 psi) and the automatic drain removes the need to watch the bowl. This code keeps the standard 40 um element - the choice for general cylinder and valve duty, with the W option there if 5 um is needed. The F1 suffix selects the square MPa gauge, preferred where the dial is read edge-on on a crowded panel; the round C gauge and psi/bar scales are the other decodable choices, and G or NPT threads can replace the PT standard.
Because flow for this series is published as curves and not a single rating, ask us to confirm sizing from the datasheet before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C1 regulator with a GF400-C1 filter on that branch.
Airtac GC FRL Unit GC400C15F1 FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a rated flow for the 400 size here. Give us your line pressure and the total air consumption of the equipment to be fed, and we will confirm the datasheet flow figures on request and check that the 400 size with PT1/2 ports is the right selection.
The F1 suffix on GC400C15F1 selects the square pressure gauge with MPa scale, which is the style suited to panel-mounted sets where the dial is read straight on. The alternative C suffix specifies a round external gauge, also available with MPa, psi or bar scales. Both read the regulated outlet pressure; the choice is purely which gauge style and scale your panel and your operators prefer.
