About the AirTAC GC400-15 FRL Unit (GC40015MC1WK)
The AirTAC GC series is the three-piece F.R.L. combination: separate filter, regulator and lubricator units built into one set, cleaning, regulating and lubricating the compressed air supply at a single point. This GC40015MC1WK is size 400 with a 1/2 in PT port. The W code selects the 5 um filter element, the bowl is manually drained, the standard regulator covers 0.05-0.9 MPa (7-130 psi) with manual drain, and a round external gauge on the 1 (MPa) scale is included. The K option adds a reverse-check valve that holds downstream pressure if the upstream supply is lost. Maximum working pressure is 1.0 MPa (145 psi); the size 400 filter and lubricator bowls are polycarbonate and the medium is compressed air only.
This is a genuine AirTAC part. The G series is offered in sizes 200, 300, 400 and 600 with PT, G(BSPP) or NPT threads, differential-pressure, automatic or manual drains, and 40 um or 5 um (W) elements. Flow figures for the family are published as curves, not a single rating, so ask us to 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 0.05 - 0.9 MPa (7 - 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.
Model Code: AirTAC GC400-15 FRL Unit (GC40015MC1WK)
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|

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 (GC40015MC1WK) Is Used
Bottling line conveyor air
Condition the air feeding conveyor stop-gates, pushers and rail-adjust cylinders on a bottling line. The reverse-check valve holds the circuit during brief upstream drops so gated bottles are not released mid-change, while the lubricator feeds the gate cylinders.
Injection molding take-out grippers
Supply the end-of-arm gripper circuit on an injection molding machine: the 5 um element gives finer filtration ahead of the gripper valves, the regulator fixes gripping pressure, and the check valve guards the set pressure between molding cycles.
Trailer brake-test rig (shop use)
Feed a workshop rig that exercises pneumatic trailer components: filtered, regulated and lubricated air at a fixed 1/2 in point, with the check valve holding the rig's downstream pressure while the shop compressor cycles.
Is the AirTAC GC400-15 FRL Unit (GC40015MC1WK) the Right Station?
Choose this code when you want the size 400 / 1/2 in PT combination with fine 5 um filtration and the check-valve option in one set - useful where a momentary supply interruption should not dump the downstream circuit. The drain is manual, so an operator bleed is part of the routine; pick automatic or differential-pressure drain codes for unattended duty. The round gauge reads MPa; psi (2) and bar (3) scale codes exist if your team works in other units. PT is the standard thread and G(BSPP) or NPT can be ordered. Flow is published as curves rather than a single rating, so ask us to confirm datasheet sizing for 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 0.05 - 0.9 MPa (7 - 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 (GC40015MC1WK) FAQ
We do not quote a single rated flow because AirTAC publishes G-series performance as flow curves instead of one number. Tell us your working pressure and demand and we will confirm the datasheet figures and check the size 400 selection against your application on request.
K fits a reverse-check valve in the set, so downstream pressure is held if the upstream supply drops. If your circuit can tolerate a pressure dump during a supply interruption, order the same code without K (GC40015MC1W); otherwise K adds that hold-up behaviour at the same 1/2 in PT size and 5 um filtration.
