Airtac GFC Combination Unit GFC400C15C1
The AirTAC Airtac GFC Combination Unit GFC400C15C1 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the Airtac GFC Combination Unit GFC400C15C1
GFC400C15C1 is a genuine AirTAC G-series two-unit air preparation set: a filter regulator and a lubricator supplied together as one 2-piece combination, so the same PT1/2 (1/2 in) ported line gets water and particulate removal, pressure regulation and oil-mist lubrication. This configuration carries the standard 40 um filter element, a differential-pressure drain on the filter bowl, and an external round pressure gauge with MPa scale on the regulator. It is rated for compressed air at up to 1.0 MPa (145 psi) and -5 to 70 C (non-freezing); the bowls on the filter and lubricator are polycarbonate at size 400.
AirTAC builds the GFC two-unit format in 200, 300, 400 and 600 sizes with ports from 1/8 to 1 in, and this set is one point in that catalogue. Options include G (BSPP) or NPT threads, automatic or manual drains, a 5 um element, square or round gauges in MPa, psi or bar scales, and a reverse/check valve. Flow for G-series units is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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-C1 filter regulator and GL400-C1 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 GFC Combination Unit GFC400C15C1 Is Used
Packaging line air prep
Feeding regulated, filtered and lubricated air to case packers and carton sealers on a packaging line, with the lubricator section oiling cylinders and directional valves in daily duty.
Conveyor divert and stop cylinders
Supplying the pneumatic diverters, stops and pushers along a conveyor system, where one PT1/2 set filters, regulates and lubricates the air feeding several actuators.
Assembly fixture clamping
Prep air for pneumatic swing clamps and hold-downs on a machining or assembly fixture, holding the regulator at the pressure the clamp circuit was designed around.
Is the Airtac GFC Combination Unit GFC400C15C1 the Right Set?
Size 400 with PT1/2 ports sits in the middle of the G-series range; step to 200/300 for smaller ports or to 600 for larger ones. The differential-pressure drain here behaves automatically as the bowl loads; the A and M suffixes switch to automatic float or manual draining if you prefer. The 40 um element is the standard grade - add W for 5 um where downstream valves want finer air. Code C1 selects the external round gauge on an MPa scale; the embedded square gauge and psi or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT orderable, and a bracket is included. Flow in this family is published as curves, not one rated number, so send us your application flow and we will confirm sizing from the datasheet before you order.
Quick checklist
- ✓ Body size for your peak flow (See datasheet 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-C1 filter regulator on its own.
Airtac GFC Combination Unit GFC400C15C1 FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not quote one number. Tell us your required flow and upstream pressure and we will confirm the datasheet curve for this PT1/2 set on request before you order.
It selects the external round pressure gauge on the regulator with an MPa scale. The other catalogue options are the embedded square gauge, or round gauges in psi (code 2) or bar (code 3) scales - just change the trailing gauge code.
