About the Airtac GC FRL Unit GC400C15MC1W
The AirTAC GC400C15MC1W is a three-piece F.R.L. combination: separate air filter, pressure regulator and lubricator in line. This 400-size unit takes PT1/2 ports, drains its filter bowl manually, and filters to the finer 5 um grade (the W option) for cleaner downstream air. A round external gauge reads regulated pressure in MPa.
This is a genuine AirTAC part from the G series, offered in 200, 300, 400 and 600 sizes with drain-type, filter-grade, gauge and thread options (PT standard, G and NPT to order). Flow 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 GC400C15MC1W Is Used
Air supply to a laboratory autoclave line
Installed ahead of the control valves on a lab autoclave and steriliser installation, this set delivers 5 um-filtered, regulated, lubricated air so that gate and loading cylinders operate reliably in a hygiene-conscious environment.
Pneumatic clamping on an assembly press
Mounted at the inlet of a fixture-clamping circuit on an assembly press, it supplies clean air at a fixed regulated pressure so clamps hold workpieces consistently, with the 5 um element protecting fine-metering valves in the circuit.
Dock leveller and trailer restraint controls
Fitted in the power pack of a loading-dock leveller, the unit conditions the air driving the leveller and restraint cylinders, keeping moisture and particles out of the control valves on a busy shipping bay.
Is the Airtac GC FRL Unit GC400C15MC1W the Right Station?
GC400C15MC1W pairs the 400 size with PT1/2 ports and the 5 um element, the right choice when downstream valves or actuators need cleaner air than the standard 40 um grade delivers. If demand is lighter, the 300 size on 3/8" covers smaller lines; heavier demand steps up to the 600 size. Manual drain means an operator clears the bowl on a routine walk-round; automatic or differential-pressure drain variants exist for unattended points.
The gauge here is the round external type on an MPa scale; embedded square gauges and psi or bar scales are alternatives. Thread is PT as standard, with G (BSPP) and NPT as orderable options. Flow appears only 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 (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 GC400C15MC1W FAQ
AirTAC publishes G-series flow as characteristic curves rather than a single rated value, so we cannot honestly quote one number. Share your line pressure and consumption and we will confirm the sizing and datasheet flow data for this 400-size, PT1/2 unit on request.
W selects the 5 um filter element instead of the standard 40 um grade, giving finer particulate removal in the filter bowl. Everything else in the code stays the same: 400 size, PT1/2 ports, manual drain, standard regulator with a round MPa gauge, and no reverse valve.
