About the AirTAC GC400-15 FRL Unit (GC40015F1W)
The GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator supplied as one set. This GC40015F1W is the size 400 unit with PT1/2 ports, the 5 um filtration grade (W), a differential-pressure drain on the filter bowl and an embedded square gauge reading in MPa. In use it filters water and particulate from the compressed air, holds a set downstream pressure and adds oil mist in one installation, with regulation adjustable from 0.15 to 0.9 MPa (20-130 psi) with this drain type.
This is a genuine AirTAC part. Maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the size 400 bowls are polycarbonate. The G series is also available in sizes 200, 300, 400 and 600, with G (BSPP) or NPT threads, automatic or manual drains, 40 um standard elements and other gauge scales as options. Flow is published as curves rather than a single rating, so ask us and we will 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: GF400-15 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 (GC40015F1W) Is Used
CNC machining centre air preparation
Feeds the tool-clamp and pallet-change circuits of a machining centre: the 5 um element removes water and particulate ahead of the directional valves, the regulator holds clamp pressure and the lubricator mists the cylinders.
Bottling line stopper and pusher cylinders
Conditions the air feeding conveyor stoppers, diverts and pushers on a filling line, with regulated pressure for controlled product handling and oil mist for cylinder life.
Case-packing machine cylinder supply
Supplies filtered, regulated and lubricated air to the clamp, flap-fold and ejector cylinders on an end-of-line case packer, with the MPa gauge matching the plant's instrument standard.
Is the AirTAC GC400-15 FRL Unit (GC40015F1W) the Right Station?
Move to size 400 with the 1/2 in. port when your line's air demand outgrows a size 200 or 300 set. Drain: this unit carries the differential-pressure drain (default); automatic (A) and manual (M) versions can be ordered. Filter grade: 5 um (W) here versus the 40 um standard - choose 5 um where finer protection for valves and cylinders matters. The embedded square gauge reads in MPa; psi (code 2) and bar (code 3) scales exist. Thread: PT is the standard; G (BSPP) and NPT are catalogue options to order. Flow is published as curves, not one rated number, so ask us to confirm sizing against your application before you order.
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 (GC40015F1W) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number here. Send us your required flow and working pressure and we will confirm the datasheet figures on request before you order.
Yes. The GC400 series is offered with an embedded square gauge on an MPa (code 1), psi (code 2) or bar (code 3) scale - for example GC40015F2 reads psi and GC40015F3W reads bar. An external round gauge is also a catalogue option.
