AirTAC GFC400-15 Combination Unit (GFC40015AF2)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015AF2) 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 40 µm element, a automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015AF2)
The AirTAC GFC40015AF2 is a two-unit air-treatment set combining a filter regulator with a lubricator: it strips water and particulate, regulates downstream pressure, and delivers oil mist. This version is the 400 size with PT1/2 ports, an automatic drain, the standard 40 um filter element, and an embedded square gauge scaled in psi. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) with the automatic drain, and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the G series, which runs from size 200 to 600 with optional G (BSPP) and NPT threads, manual or differential-pressure drains, 5 um elements, and gauge scale choices. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet and sizing 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 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.

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 (GFC40015AF2) Is Used
Press-shop pneumatic clamps
Regulating and lubricating the clamp and ejector cylinders on a stamping press's periphery, with the psi gauge matching the plant's US-style instrument standard.
Carton-forming packaging machines
Conditioning supply to the vacuum-blowoff and flap-fold cylinders on a carton-forming machine, where general 40 um filtration and steady regulation keep the cycle repeatable.
Plant air drops for air tools
Feeding a 1/2-inch shop-air drop that serves impact tools and hose reels, combining water removal, pressure setting and oil mist at the point of use.
Is the AirTAC GFC400-15 Combination Unit (GFC40015AF2) the Right Set?
The 400 size with PT1/2 ports suits circuits specified at 1/2 inch where demand is beyond the 200/300 bodies - match the curve to your flow. The automatic drain clears condensate without daily attention. The standard 40 um element is the economical choice for general-purpose actuation; step to the W variant for 5 um where equipment needs finer filtration. The square psi gauge suits US-specified panels. PT is the standard thread; G (BSPP) and NPT are catalogue options to order.
Flow is published as curves, not a single rating, so give us your flow and pressure conditions and we will confirm sizing against 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
- ✓ 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 (GFC40015AF2) FAQ
AirTAC publishes G-series flow as performance curves rather than one rated figure, so we do not quote a single number. Share your required flow and pressure and we will confirm the sizing from the datasheet on request before you order.
The F2 code specifies the embedded square gauge with a psi scale, suiting panels specified in US units. The alternative F1 variant carries the same square gauge scaled in MPa, and both are catalogue choices across the regulator-equipped G-series sets.
