AirTAC GFC400-15 Combination Unit (GFC40015C1WK)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015C1WK) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/2" ports, a 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015C1WK)
The AirTAC GFC series is a two-unit air preparation set: a filter-regulator that removes water and particulate and holds downstream pressure, paired with a separate lubricator that meters oil mist into the line. This GFC40015C1WK adds a reverse (check) valve to the configuration, and is built on the 400 size with PT1/2 (PT) ports, a 5 um filter element, differential-pressure drain bowls and an external round gauge on the MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi), working temperature is -5 to 70 C non-freezing, and at the 400 size both bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GFC family spans sizes 200, 300, 400 and 600 with differential-pressure, automatic or manual drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, G (BSPP) or NPT thread options, and the K check-valve option shown here. Flow is published as curves rather than a single rating - ask us to confirm sizing and the datasheet 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 set has no separate bracket code — the two 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination set. Constituent units, orderable separately as spares: GFR400-15 filter regulator and GL400-15 lubricator.
Size Class & How It Differs From GC
- GFC200PT1/8" - PT1/4"
- GFC300PT1/4" - PT1/2"
- GFC400PT3/8" - PT1/2"
- GFC600PT3/4" - PT1"
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Where the AirTAC GFC400-15 Combination Unit (GFC40015C1WK) Is Used
Automated assembly station
Preparing air for multi-station screwdriving and pressing fixtures, where the check valve helps hold the regulated circuit against reverse flow between cycles.
Process valve actuation skid
Supplying pneumatic quarter-turn actuators on a water-treatment skid, with filtered, regulated, lubricated air and an MPa gauge matching the panel instrumentation.
Bottling line diverters
Running gate and diverter cylinders on a bottling conveyor, where the 5 um element protects pilot valves and the lubricator conditions the actuator air.
Is the AirTAC GFC400-15 Combination Unit (GFC40015C1WK) the Right Set?
Choose the 400 size with PT1/2 ports when your supply line and downstream demand sit in the mid-to-large range of the 200-600 family. The K suffix fits a reverse (check) valve that blocks reverse flow through the unit - select it where backflow could disturb the regulator setting or the line; without K, the same set ships without it. Drain is differential-pressure here, giving a regulator setting range of 0.15-0.9 MPa (20-130 psi); the manual-drain version widens this to 0.05-0.9 MPa (7-130 psi). The 5 um element offers finer filtration than the 40 um standard, and the round gauge reads MPa with psi or bar variants available. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order.
Flow is published as curves, not a single rating - 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
- ✓ Two-unit (GFC) or three-unit (GC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter regulator 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 set 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, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR400-15 filter regulator on its own.
AirTAC GFC400-15 Combination Unit (GFC40015C1WK) FAQ
AirTAC publishes G-series flow as curves, not as a single rated number, so we do not state a figure here. Share your inlet pressure, port size and downstream consumption and we will confirm the sizing and send the datasheet on request.
K means a reverse (check) valve is fitted, blocking reverse flow through the set. Drop the K for the identical two-unit F.R.L. without the check valve. The rest of this code decodes as: 400 size, PT1/2 PT-thread ports, C1 round gauge on MPa scale, W 5 um filter element, and differential-pressure drain.
