About the AirTAC GC400-15 FRL Unit (GC40015F2)
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 GC40015F2 is the size 400 unit with PT1/2 ports, the standard 40 um filter element, a differential-pressure drain and an embedded square gauge reading in psi - a natural match for US-market plants working in imperial units. It filters water and particulate, regulates downstream pressure from 0.15 to 0.9 MPa (20-130 psi) with this drain type, and lubricates the air in one installation.
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 GC family is also offered in sizes 200, 300, 400 and 600, with G (BSPP) or NPT threads, automatic or manual drains, a finer 5 um (W) element and MPa or bar 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 (GC40015F2) Is Used
Furniture-plant nailer and stapler stations
Conditions the air feeding pneumatic nailers and staplers at furniture assembly stations, with the psi gauge reading in the units the shop floor already uses and the lubricator serving the tools.
Assembly-bench air tool drops
Feeds bench-mounted air tools and small cylinders along a manual assembly line: 40 um filtration handles general plant air, the regulator sets working pressure and the lubricator mists the tools.
Tire changer and service bay equipment feed
Supplies filtered, regulated and lubricated air to tire changers and impact equipment in an automotive service bay, with the size 400 port carrying the demand of shared drops.
Is the AirTAC GC400-15 FRL Unit (GC40015F2) the Right Station?
Size 400 with the 1/2 in. port suits applications whose demand has outgrown a size 300 set. Filter grade: this unit uses the standard 40 um element (no W in the code); specify the 5 um (W) version where valves or cylinders need finer protection. Drain: differential-pressure as decoded here, with automatic (A) and manual (M) as orderable alternatives. The embedded square gauge reads psi; MPa (1) and bar (3) scales exist for other plants. Thread: PT is the standard, and G (BSPP) or NPT can be ordered. 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 (GC40015F2) FAQ
AirTAC publishes GC-series flow as curves rather than a single rated number, so we do not quote one here. Share your required flow and working pressure and we will confirm the figures from the datasheet on request before you order.
No W in the code means the standard 40 um element, which suits general plant air. If your valves or cylinders need finer protection, order the same set with W added - for example GC40015F2W - for the 5 um element.
