About the Airtac GC FRL Unit GC400C15AF1K
The AirTAC GC series is a three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator serving one compressed-air line. This size 400 configuration carries a PT1/2 (1/2 in) port, the standard 40 um filter element, an automatic drain on the filter bowl, an embedded square pressure gauge scaled in MPa, and a fitted check (reverse) valve that helps hold the downstream setting when the upstream supply dips. Maximum working pressure is 1.0 MPa (145 psi), the filter and lubricator bowls are polycarbonate at 400 size, and the temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, embedded square or external round gauges in MPa, psi or bar scales, the check valve as an option (order without K for a plain set), and G (BSPP) or NPT threads as catalogue alternatives to the PT standard. Flow is published as curves rather than a single rating, so we confirm datasheet and sizing figures 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 GC400C15AF1K Is Used
Injection moulding core-pull
Supplying filtered, regulated and lubricated air to the core-pull and ejector cylinders on an injection moulding machine, with the check valve helping hold the set pressure through mould-cycle supply dips.
Textile loom air prep
Conditioning the compressed air feeding the doffing and shed-change cylinders on a weaving loom, where the automatic drain keeps the bowl clear through continuous multi-shift running.
Maintenance shop air drops
Serving the wall drops of a plant maintenance shop, giving technicians filtered, pressure-set and lubricated air for impact tools, test rigs and clamp fixtures.
Is the Airtac GC FRL Unit GC400C15AF1K the Right Station?
Size 400 with the PT1/2 port suits lines whose consumption has outgrown a GC300 (3/8 in) set, with GC600 covering 3/4 in headers. The automatic drain removes condensate without operator attention; choose manual drain for supervised duty or differential-pressure drain for the standard configuration. The 40 um element is the standard grade for general plant air; step to 5 um (W) only where downstream components need finer filtration. This set carries the embedded square gauge in MPa; the round external gauge and psi or bar scales are also available. The trailing K adds the check valve - omit it from the code if you do not need that function. PT is the standard thread; G (BSPP) and NPT are orderable catalogue options.
Flow is published as curves, not a single rated figure, so send us your pressure and consumption requirements and we will confirm the correct size 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 GC400C15AF1K FAQ
AirTAC publishes GC-series flow as curves rather than a single rated figure, so we do not state one number on this page. Tell us your working pressure and air consumption and we will confirm the flow data from the datasheet on request.
GC keeps the filter, regulator and lubricator as three separate units, which makes servicing or swapping individual stages straightforward; GFC pairs a combined filter-regulator body with a lubricator in two units. Choose GC where you want full filtration, regulation and oil-mist lubrication with each stage serviceable on its own.
