AirTAC GFC400-15 Combination Unit (GFC40015ALC1)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015ALC1) 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 (GFC40015ALC1)
GFC40015ALC1 is an AirTAC G-series two-unit air-treatment set: a GFR400 filter-regulator paired with a GL400 lubricator, covering filtration, pressure regulation and oil-mist lubrication in two pieces. This configuration is sized for 1/2 in. ports with PT thread, uses an automatic drain on the filter bowl, carries the standard 40 um filter element, and is the low-pressure (L) type. It comes with a round external gauge reading in MPa. Maximum working pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing. At size 400 the bowls on both units are PC (polycarbonate).
This is a genuine AirTAC part from the GFC series. The same set is offered in sizes 200, 300, 400 and 600 with a choice of PT, G (BSPP) or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, and round or square gauges in MPa, psi or bar scales. AirTAC publishes flow for these units as curves rather than a single rated figure, so we confirm flow and full datasheet details 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 (GFC40015ALC1) Is Used
Pneumatic valve manifold supply
Feeding filtered, regulated and lubricated air to directional control valves on an automated packaging line from a 1/2 in. take-off point, keeping the low-pressure circuit conditioned before the manifold.
Conveyor clamp and pusher cylinders
Conditioning supply air for the clamp and pusher actuators along a bottling conveyor, with oil mist carried downstream so cylinder seals run on lubricated air.
Assembly-cell air drop
A treatment point at a machine shop assembly drop, filtering and regulating the shop main before it feeds air tools and clamping fixtures on the cell.
Is the AirTAC GFC400-15 Combination Unit (GFC40015ALC1) the Right Set?
Size and port are the first decision: 400 with 1/2 in. PT suits mid-size plant air take-offs; step up to 600 (1 in.) or down to 300 or 200 if your line volume differs - match the step to required flow, which we confirm from the flow curves before you order. Drain choice: automatic empties the filter bowl without operator attention; manual gives deliberate control; the differential-pressure default triggers on pressure drop. Filter grade: 40 um is standard for general plant air, 5 um (W) where finer particulate protection matters. Gauge: this set carries a round gauge on the 1 (MPa) scale; square-gauge (F) variants and psi or bar scales are orderable. Thread: PT is standard; G and NPT are catalogue options.
As the low-pressure (L) type, the catalogue adjustment range quoted for the automatic-drain version is 0.15-0.9 MPa (20-130 psi); we confirm the L-type adjustment limits against the datasheet on request 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 (GFC40015ALC1) FAQ
AirTAC publishes flow for the GFC series as curves, not as a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the flow from the datasheet on request before you order.
C selects the round external gauge and 1 sets its scale to MPa. If you prefer the square gauge instead, or a psi (2) or bar (3) scale, the F2/F3 or C2/C3 variants of the same set are orderable - just ask us to confirm availability for your configuration.
