About the AirTAC GC400-15 FRL Unit (GC40015AC1)
GC40015AC1 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one 3-piece set. This configuration is size 400 with a PT1/2 (1/2 in) port, automatic drain on the filter bowl, the standard 40 um filter element and a round external pressure gauge reading in MPa. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) and the set carries a bracket. Medium is compressed air only; maximum working pressure is 1.0 MPa (145 psi), and operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, in PT (standard), G (BSPP) or NPT threads, with differential-pressure, automatic or manual drains, and 40 um or 5 um (W) filter elements. The filter bowl on this 400 size is polycarbonate. Flow is published as curves rather than a single rating; ask us and we will confirm the datasheet and sizing for your application.

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 (GC40015AC1) Is Used
Carton-sealing packaging line
Supplies filtered, regulated and lubricated air to the clamp and flap-fold cylinders of a carton sealer, with the automatic drain coping with condensate from a busy plant-air drop.
CNC machining-center tool change
Feeds the tool-changer and clamping cylinders on a machining center, conditioning the shop air drop before it reaches position-critical actuation.
Sortation conveyor diverters
Conditions air for the pusher and diverter cylinders along a sortation conveyor, giving the line one combined filter, regulator and lubricator station.
Is the AirTAC GC400-15 FRL Unit (GC40015AC1) the Right Station?
Size 400 with a 1/2 in PT port sits in the upper-middle of the GC range; step down to 300 or up to 600 depending on the air demand of your line. The automatic drain ejects condensate without operator attention, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are catalogue alternatives. The standard 40 um element is the default; choose the 5 um W option only when downstream equipment needs finer filtration. The round MPa gauge is external; an embedded square gauge (MPa, psi or bar scale) is the other catalogue choice. PT is the standard thread, with G and NPT available as options, and a bracket is included. Flow is published as curves, not a single rating, 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 (GC40015AC1) FAQ
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote one number here. Ask us and we will confirm the datasheet and check the 400-size, 1/2 in port unit against your required flow before you order.
The automatic drain (suffix A in this model) discharges accumulated condensate from the filter bowl on its own, without anyone opening it. Manual drains require an operator to open the bowl drain, and the differential-pressure drain is the series default. All three are catalogue options on the GC series.
