About the Airtac GC FRL Unit GC400C15NW
The GC400C15NW is a genuine AirTAC three-piece F.R.L. combination - separate air filter, pressure regulator and oil-mist lubricator - for 1/2 inch PT ports. The W code fits the finer 5 um filter element instead of the standard 40 um one, and the filter bowl drains by the default differential-pressure method; no pressure gauge is fitted (N). It cleans moisture and fine particulate from the air, holds downstream pressure adjustable from 0.15-0.9 MPa (20-130 psi), and meters oil mist to lubricate downstream equipment.
This is a genuine AirTAC part in the G series size 400 range, which offers sizes 200, 300, 400 and 600 with a choice of ports, threads, drains, 40 um or 5 um filter grades, gauge options and a check valve option. Maximum working pressure is 1.0 MPa (145 psi), service temperature is -5 to 70 C (non-freezing), and the bowls on this size are PC (polycarbonate). Flow is published as curves rather than a single rated figure, so we will confirm datasheet flow 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 GC400C15NW Is Used
Laboratory air services
Conditioning the compressed air feeding a laboratory's pneumatic valves and sample-handling actuators, where the 5 um element keeps fine contamination out of sensitive pilot circuits and the lubricator serves air-driven bench equipment.
Electronics assembly tooling
Mounted on the air drop for an electronics assembly line, it supplies clean, regulated, lubricated air to pick-and-place peripherals and screwdriver stations, with finer filtration protecting small pilot valves.
Paint booth air prep
Installed ahead of a spray booth's air supply, the 5 um element reduces particulate in the air reaching the atomisation side of the process, while the regulator holds a steady setting for consistent gun operation.
Is the Airtac GC FRL Unit GC400C15NW the Right Station?
Choose the 400 size / 1/2 inch PT port for mid-to-large air lines, stepping to another size where the circuit demand differs. The W here means the 5 um element - pick it when valves, probes or instruments need finer filtration than the standard 40 um; note that finer elements load faster and need more attention to the drain. Drain type is the differential-pressure default, with automatic (A) and manual (M) orderable. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. No gauge is fitted (N); gauge variants can be ordered if a pressure readout is needed. 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 (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 GC400C15NW FAQ
There is no single rated flow figure to quote: AirTAC publishes flow for this series as performance curves. Send us your application details and we will confirm the datasheet flow figures and check the sizing for you on request.
The W code fits the finer 5 um element, which suits circuits with sensitive pilot valves, instruments or process air needs; the standard 40 um element is the economical choice for general actuation. The drain, regulator range, 1/2 inch PT ports and gauge-free configuration are otherwise the same.
