AirTAC GFC400-15 Combination Unit (GFC40015AC1)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015AC1) 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 (GFC40015AC1)
GFC40015AC1 is an AirTAC G-series two-unit air-preparation set for a 1/2 in PT line: a 400-size filter regulator paired with a matching lubricator, so one set removes water and particulate, holds a set working pressure and meters oil mist into the air stream. In this configuration the A code sets an automatic drain on the polycarbonate filter bowl, the standard 40 um element is fitted, and C1 specifies the external round pressure gauge with an MPa scale. Regulating range with automatic drain is 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the set operates from -5 to 70 C.
This is a genuine AirTAC part. The G series is available in 200, 300, 400 and 600 sizes, with differential-pressure, automatic or manual draining, 40 um standard or 5 um (W) filtration, MPa, psi or bar gauge scales, and PT as the standard thread with G (BSPP) and NPT as order options. AirTAC publishes flow for this series as curves rather than a single rating, so we confirm the datasheet figures and sizing on request before you order.

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 (GFC40015AC1) Is Used
Pneumatic stamping press feed
Feeds the press cylinders on a sheet-metal stamping line from a 1/2 in plant main: the filter-regulator half strips water and chips and holds a fixed working pressure while the lubricator mists oil to the press valves and cylinders.
Carton sealing line
Supplies the glue-head and flap-fold cylinders of a carton sealer with clean, regulated, lubricated air so the machine's valves keep cycling through a full shift.
Robotic weld cell clamps
Air prep for the part-clamping fixtures around a robotic welding cell, where the external round MPa gauge lets the cell technician set and read fixture pressure at a glance.
Is the AirTAC GFC400-15 Combination Unit (GFC40015AC1) the Right Set?
Real, decodable choices: this 400 size carries a 1/2 in port, so step to 200 or 300 for smaller ports or to 600 for larger mains, matched to the flow curve your demand needs. Draining here is automatic (A); manual and differential-pressure drains are alternatives, and with a manual drain the regulating range widens to 0.05-0.9 MPa (7-130 psi) from 0.15-0.9 MPa (20-130 psi). The element is the standard 40 um; gauge scales are MPa, psi or bar, and the embedded square gauge can be ordered instead of this external round gauge. Thread is PT as standard, with G (BSPP) and NPT available to order. AirTAC publishes flow as curves, not one rated figure, 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
- ✓ 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 (GFC40015AC1) FAQ
AirTAC publishes G-series performance as flow curves rather than a single rated figure, so no one number is quoted here. Tell us your line pressure and air demand and we will confirm the flow and datasheet figures for this 1/2 in two-unit set on request.
The A code fits an automatic condensate drain, so the bowl empties without operator attention. Manual and differential-pressure drains are alternatives in the same 400-size set; with a manual drain the regulating range is 0.05-0.9 MPa (7-130 psi) instead of 0.15-0.9 MPa (20-130 psi).
