Airtac GFC Combination Unit GFC400C10C1K
The AirTAC Airtac GFC Combination Unit GFC400C10C1K 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 GFC400C10C1K
The GFC400C10C1K is a genuine AirTAC G-series two-unit air-treatment set combining a filter regulator and a lubricator, so filtration, pressure regulation and oil-mist lubrication come as one matched pair. The K suffix means a reverse (check) valve is fitted, so air flows one way through the set and downstream pressure is held when upstream supply drops. This configuration is size 400 with PT3/8 ports (PT is the standard thread; G and NPT are catalogue options), 40 um standard filtration, differential-pressure drain bowls in polycarbonate, and an external round gauge on an MPa scale. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjustment range with differential-pressure drain is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C, non-freezing.
The G series is offered in sizes 200, 300, 400 and 600, with automatic or manual drain options, a 5 um fine-filtration element (W suffix), embedded square or external round gauges, and G (BSPP) or NPT threads to order. Flow is published as curves rather than a single rated figure, so we confirm flow and 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. 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 GFC400C10C1K Is Used
Pick-and-place grippers
Conditioning air for cylinder-actuated grippers on a robotic pick-and-place cell, with the check valve helping hold the circuit between cycles.
Actuated process valves
Supplying filtered, regulated and lubricated air to quarter-turn pneumatic actuators on process valves in a dosing or transfer skid.
High-cycle packaging cylinders
Feeding the fast-cycling cylinders of a form-fill-seal packaging machine with clean, regulated, oil-misted air.
Is the Airtac GFC Combination Unit GFC400C10C1K the Right Set?
Size first: the 400 frame with PT3/8 ports sits mid-range in the 200/300/400/600 G-series ladder, so step up or down against your pipe size and demand. The K suffix is the deciding difference here: choose it where you want the built-in reverse (check) valve to hold the circuit when supply is interrupted. Drain is differential-pressure as standard, with automatic or manual available; filtration is 40 um standard or 5 um with W; the C1 suffix gives an external round gauge in MPa, with psi or bar scales and an embedded square gauge as alternatives. Thread is PT standard, with G (BSPP) and NPT as order options. Since AirTAC publishes flow only as curves, ask us to confirm the datasheet figures 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 GFC400C10C1K FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Share your flow demand and we will confirm sizing against the datasheet curves on request before you order.
The K suffix indicates that a reverse (check) valve is fitted in the set, so flow passes one way through the unit. If you do not need this function, the same configuration is available without it as GFC400C10C1.
