Airtac GC FRL Unit GC400C15AN
The AirTAC GC FRL Unit GC400C15AN 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GC FRL Unit GC400C15AN
The AirTAC GC series combines three separate units - filter, regulator and lubricator - into one F.R.L. set. This GC400C15AN is the size 400, 1/2 in PT port version with an automatic drain on the filter bowl, the standard 40 um filter element, a standard-type regulator and no gauge fitted (the N in the code). In use it strips water and general particulate from the compressed air, holds downstream pressure at your set point within the 0.15-0.9 MPa (20-130 psi) automatic-drain adjustment range, and feeds oil mist to downstream tools and cylinders. Maximum inlet pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C, and the 400-size bowls are polycarbonate.
This is a genuine AirTAC part. The G series covers sizes 200, 300, 400 and 600, with options for drain type, 5 um fine filtration, embedded square or external round gauges in MPa, psi or bar scales, a reverse valve, and G (BSPP) or NPT threads in place of the PT standard. AirTAC states flow as curves rather than one rated figure, so we confirm the datasheet and sizing 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 GC400C15AN Is Used
Pneumatic hand-tool drops in maintenance shops
Filtering, regulating and lubricating the air feeding impact wrenches, grinders and riveters at maintenance-shop workstations, where the 40 um element handles general plant air.
Modular conveyor gating circuits
Conditioning air for gate, stopper and lift cylinders along modular conveyor systems, with the automatic drain clearing condensate without scheduled blowdown rounds.
Plant-wide 1/2 in branch headers
Installed on 1/2 in branch headers serving a production floor, giving each branch its own filtered, regulated and lubricated supply independent of the main header pressure.
Is the Airtac GC FRL Unit GC400C15AN the Right Station?
Size 400 with a 1/2 in port is a solid mid-to-upper choice in the G series; compare against size 300 or 600 based on the flow your line demands. This version pairs the automatic drain (no operator attention needed) with the 40 um standard element, which suits general plant air; order the W variant if you need 5 um fine filtration. The N code means no gauge - pick a variant with a square or round gauge, in MPa, psi or bar scale, if operators need a local pressure readout. G or NPT threads are orderable instead of PT. AirTAC publishes flow only as curves, so ask us to confirm sizing against your application before you order.
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 GC400C15AN FAQ
There is no single rated flow figure to quote: AirTAC publishes flow as performance curves, not one number. Give us your line pressure and air demand and we will confirm the datasheet curve and correct size on request before ordering.
N means no gauge is fitted on this set - the regulator is set by feel or against a remote instrument. If you want a local readout, the same GC400 in 1/2 in PT with automatic drain is available with an embedded square gauge or an external round gauge in MPa, psi or bar scale.
