Airtac GFC Combination Unit GFC400C10AC1W
The AirTAC Airtac GFC Combination Unit GFC400C10AC1W 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 GFC400C10AC1W
GFC400C10AC1W is an AirTAC G-series two-unit air-treatment set combining a filter-regulator and a lubricator in one two-piece assembly, so filtration, regulation and oil-mist lubrication come from a single mount. This size 400 unit serves 3/8" ports on PT thread (G and NPT are orderable options). The W in the code specifies the finer 5 um filter element instead of the standard 40 um, the drain is automatic, and the set includes a pressure gauge with MPa scale. Regulated pressure is adjusted within 0.15-0.9 MPa (20-130 psi) on this automatic-drain version, maximum inlet pressure is 1.0 MPa (145 psi), and at size 400 both bowls are polycarbonate. Operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part supplied by airdistr.com for the US market. The G-series spans sizes 200, 300, 400 and 600, with manual or differential-pressure drains, gauge-scale options and G/NPT thread variants. Rated flow is published as curves rather than a single figure, so we 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-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 GFC400C10AC1W Is Used
Laboratory automation air supply
Autosamplers and small pneumatic actuators on a lab bench take air through this set, where the 5 um element supports cleaner supply to sensitive pilot circuits and the lubricator feeds the actuators.
Electronics assembly clamping fixtures
Clamp and hold-down cylinders on an electronics assembly fixture are fed from this 3/8" set, with the finer 5 um grade helping keep particulates out of the small pilot valves.
Pneumatically actuated process valves
Quarter-turn actuators on a process skid are supplied through this set: filtered and regulated air for positioner and pilot lines, plus oil mist for the actuator seals.
Is the Airtac GFC Combination Unit GFC400C10AC1W the Right Set?
Choose this code over GFC400C10AC1 when the 5 um element is required instead of the standard 40 um grade - useful where finer particulate capture matters downstream. Size 400 with 3/8" PT ports is the mid step of the series; we can check the published flow curves against your demand before you commit. The configuration is fixed for automatic drain (manual and differential-pressure variants exist), the finer 5 um filtration grade, a round MPa-scale gauge (psi and bar scales exist), and PT thread as standard with G (BSPP) and NPT orderable.
Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 GFC400C10AC1W FAQ
There is no single rated figure we can quote: AirTAC publishes flow for the G-series as curves. Share your operating pressure and air consumption and we will confirm the correct size from the datasheet before you order.
The W code specifies the finer 5 um element, chosen where the downstream equipment is more sensitive to particulates; the standard grade is 40 um. If you are unsure which grade your application needs, we will confirm guidance from the AirTAC datasheet on request.
