About the Airtac GC FRL Unit GC400C15C1K
GC400C15C1K is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator built up as one set that cleans, regulates and oil-mist lubricates compressed air in a single installation. This unit is sized 400 with PT1/2 (PT thread) ports, keeps the standard 40 um filter element and the default differential-pressure drain on the filter and lubricator bowls (PC polycarbonate at this size). The regulator carries a round external pressure gauge with MPa scale, and the K suffix means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply drops.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with matching ports, with a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, 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) and working temperature is -5 to 70 C (non-freezing). Flow data is published as curves rather than a single rating, so we confirm the datasheet 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-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 GC400C15C1K Is Used
CNC machining cell air supply
Feeds filtered, regulated and lubricated air to the pneumatic chucks, tool-clamp cylinders and chip-clearing blasts of a CNC lathe or machining centre, with the check valve holding clamp pressure if the main supply dips.
Bottling line conveyor controls
Supplies the stopper gates, pusher cylinders and diverter actuators along a bottling or canning conveyor, keeping water and pipe scale out of the valve stack while metering oil mist to the cylinders.
Assembly plant air drops
Installed at the wall drop feeding a row of bench assembly stations, so impact drivers, air clamps and foot-pedal cylinders on the line all draw conditioned air from one regulated point.
Is the Airtac GC FRL Unit GC400C15C1K the Right Station?
Start with the port step: this 400-size set gives PT1/2 ports, and stepping up to 600 or down to 300 changes both the port and the air handling capability - match the step to the demand of the line it feeds. With the differential-pressure drain kept here, the regulator adjusting range is 0.15-0.9 MPa (20-130 psi); choosing a manual drain variant widens the regulating range to 0.05-0.9 MPa (7-130 psi), while an automatic drain suits unattended duty. The 40 um element is the standard choice for general plant air; specify W for the 5 um element. The C1 suffix gives a round external gauge with MPa scale; F-square gauges and psi/bar scales are alternatives, and G or NPT threads can be ordered instead of the PT standard.
AirTAC publishes flow for this series as curves, not one rated figure, so ask us to confirm sizing against your application 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 GC400C15C1K FAQ
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote one number on the page. Send us your working pressure and expected air consumption and we will confirm the datasheet flow figures and check that the 400 size with PT1/2 ports suits your application - this is done on request before you order.
K indicates that a reverse (check) valve is fitted in the regulator section. If upstream supply pressure falls, the check valve holds the regulated downstream pressure instead of letting it bleed back through the unit. The same set without the K has no check valve, which is the correct choice where you want the downstream side to vent freely on shutdown.
