About the Airtac B52-GC Copper-Free Air Source Treatment Component B52-GC40015NWK
GC40015NWK is an AirTAC G-series three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built in the GC400 size with PT 1/2 in ports. In this configuration the filter carries the finer 5 um element (W), the filter bowl uses a differential-pressure drain, the regulator adjusts from 0.15-0.9 MPa (20-130 psi), no pressure gauge is fitted (N), and the trailing K means a reverse (check) valve is fitted so flow through the set is one-way. The filter and lubricator bowls are polycarbonate in the 400 size. Medium is compressed air only, with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The G series comes in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, a choice of PT (standard), G (BSPP) or NPT threads, automatic, manual or differential-pressure drains, 40 um or 5 um filtration, and gauge and check-valve options. Flow figures are published as curves rather than a single rated number; ask us and we will confirm the datasheet figures for your application.

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.
Model Code: Airtac B52-GC Copper-Free Air Source Treatment Component B52-GC40015NWK
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 B52-GC Copper-Free Air Source Treatment Component B52-GC40015NWK Is Used
Clamp-fixture hold circuit
Feeding pneumatic clamping fixtures on a welding or machining fixture, where the check valve in the set keeps the regulated side isolated from upstream supply dips.
Robotic gripper air preparation
Conditioning air for gripper and tooling circuits on a robotic cell, with the 5 um element and lubricator supporting the valve and actuator package at the end of the arm.
Trailer-dock actuation supply
Supplying treated air to dock-leveler and door-actuation cylinders at a loading bay, with the 1/2 in ports matching the bay's main air drops.
Is the Airtac B52-GC Copper-Free Air Source Treatment Component B52-GC40015NWK the Right Station?
Choose the GC400 1/2 in step when your line plumbing and air demand sit at the 1/2 in level; the 200, 300 and 600 sizes cover smaller and larger port steps. The W code selects the 5 um element over the standard 40 um. The differential-pressure drain (blank position) is hands-off; use A or M in the code for automatic or manual draining instead. K adds the reverse (check) valve - omit it if you need free two-way plumbing around the set. Gauge codes and the thread letter (blank = PT standard, G = G BSPP, T = NPT) complete the ordering code.
Because G-series flow is published as curves rather than a single rating, ask us to confirm the sizing against your application from the datasheet 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 B52-GC Copper-Free Air Source Treatment Component B52-GC40015NWK FAQ
AirTAC publishes G-series capacity as flow curves rather than a single rated figure, so we do not quote one number here. Send us your operating pressure and demand and we will confirm the datasheet curve for this GC400 1/2 in size on request.
K means a reverse (check) valve is fitted in this combination, so air passes through the set in one direction only. The same GC400 combination ordered without the K has no check valve. Ask us for the datasheet to confirm the installation details.
