About the AirTAC GC400-15 FRL Unit (GC40015C3W)
GC40015C3W is an AirTAC G-series three-unit F.R.L. combination: a separate filter, regulator and lubricator working together as one set. This size 400 configuration uses 1/2 in PT ports (PT is the standard thread), drains the bowl by differential pressure without daily attention, and carries the 5 um (W) filter element in place of the standard 40 um grade. The round external gauge on the regulator is scaled in bar. In service the set removes water and particulate from the air, holds downstream pressure steady, and meters oil mist to cylinders, valves and air tools.
This is a genuine AirTAC part. The G-series F.R.L. range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and offers drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um fine filtration, and PT, G(BSPP) or NPT threads. Maximum working (inlet) pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C, non-freezing. The bowls on the size 400 filter section are polycarbonate (PC). Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet 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: GF400-15 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 (GC40015C3W) Is Used
Robotic welding cell air supply
Feeds clean, regulated, lubricated air to the valve manifolds and grippers of a robotic welding cell, with 5 um filtration protecting fine control valves from particulate.
Carton packaging line actuation
Supplies the pneumatic cylinders and diverters on a carton forming and conveying line, where the regulator holds steady pressure as stations fire in sequence.
Assembly hall air drops
Installed at the point of use on assembly-hall air drops so impact drivers, riveters and clamping fixtures receive filtered, pressure-stabilised, oil-misted air.
Is the AirTAC GC400-15 FRL Unit (GC40015C3W) the Right Station?
Size 400 with 1/2 in ports is the upper-mid step in the G-series; step down to 300 or up to 600 depending on the air your line consumes. The differential-pressure drain here works automatically as condensate collects, but an automatic (A) or manual (M) drain can be ordered instead. The W grade gives 5 um filtration for cleaner downstream air; the standard 40 um element is the general-purpose choice. The round gauge supplied is scaled in bar; embedded square gauges scaled in MPa or psi are catalogue alternatives. PT is the standard thread - G(BSPP) and NPT versions are orderable options - and a mounting bracket is available. Flow appears 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 (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 (GC40015C3W) FAQ
AirTAC publishes flow for the G-series as curves rather than a single rated figure, so we do not quote a number here. Send us your downstream demand and working pressure and we will confirm the flow and datasheet figures for this size 400, 1/2 in PT set on request.
The standard 40 um grade suits general plant air. The 5 um (W) grade gives finer filtration where valves, instrumentation or precision actuators need cleaner air. It does not change the regulation range, which stays 0.15-0.9 MPa (20-130 psi) with the differential-pressure drain.
