About the AirTAC GC400-15 FRL Unit (GC40015C1W)
The GC40015C1W is a genuine AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied as one set. It is size 400 with a 1/2 in. PT (standard) port, fitted with the 5 um (W) fine filter element for added protection of sensitive downstream components, a differential-pressure drain, and an external round gauge reading in MPa. The regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) with this drain type, and maximum inlet pressure is 1.0 MPa (145 psi).
This is a genuine AirTAC part from the G-series range, which covers sizes 200, 300, 400 and 600 with PT, G (BSPP) and NPT thread options. On this size 400 unit the filter bowl is polycarbonate, and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm datasheet and sizing 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: GF400-15 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 (GC40015C1W) Is Used
Laboratory instrument air supply
Conditioning shop air feeding lab pneumatic devices and sample-handling actuators, where the 5 um element gives finer particle removal than the standard grade and the MPa gauge supports repeatable pressure settings.
Electronics assembly pick-and-place
Supplying filtered, regulated, lubricated air to the vacuum ejectors and slides of an electronics placement cell, with fine filtration helping protect the small pilot valves that control the heads.
Paint booth air prep panel
Serving the air-preparation point ahead of a spray-booth control panel, giving the booth technician a visible MPa setting and finer-than-standard filtration for the coating line's control valves.
Is the AirTAC GC400-15 FRL Unit (GC40015C1W) the Right Station?
Choose this W version instead of the standard GC40015C1 when the 40 um default grade is not fine enough for the valves, cylinders or instruments you are feeding; 5 um is the finer option in the range. Size 400 with the 1/2 in. PT port suits demands between the 3/8 in. size 300 and the 3/4 in. size 600 steps, and drain choice remains yours: differential-pressure (this code), automatic (A) or manual (M).
The C1 round gauge reads in MPa, with psi and bar scale gauges available in the series, and thread is PT as standard with G and NPT as catalogue options. AirTAC publishes flow only as curves, not a single rated figure, 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 (GC40015C1W) FAQ
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not state a number here. Give us your working pressure and required air consumption and we will confirm the correct size and element from the datasheet on request before ordering.
Choose 5 um (the W code) when the downstream equipment includes finely toleranced valves, instruments or applicators that need cleaner air than general machine supply; keep 40 um for normal cylinder and tool duty. This version keeps the differential-pressure drain and the MPa round gauge, so only the filtration grade changes versus the standard set.
