AirTAC GFC400-10 Combination Unit (GFC40010MNK)
The AirTAC AirTAC GFC400-10 Combination Unit (GFC40010MNK) 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 PT3/8" ports, a 40 µm element, a manual drain and regulation over 0.05 - 0.9 MPa (7 - 130 psi).

About the AirTAC GFC400-10 Combination Unit (GFC40010MNK)
The AirTAC GFC40010MNK is a two-unit air preparation set: a filter-regulator plus a lubricator, so downstream air is filtered, regulated and lubricated in one 400-size assembly. The K suffix adds a reverse (check) valve, and this configuration is sized for PT3/8 ports, has a manual drain on the filter bowl and the standard 40 um filter element, with no gauge. Maximum working pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the 400-size bowl is polycarbonate (PC).
This is a genuine AirTAC part. The G series is made in 200, 300, 400 and 600 sizes, with a choice of PT, G (BSPP) or NPT threads, drain types, filter grades and gauge options. Flow is published as curves rather than a single rated figure, so ask us and we will 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 0.05 - 0.9 MPa (7 - 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.
Model Code: AirTAC GFC400-10 Combination Unit (GFC40010MNK)
| GFC400 | G-series two-unit set, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". This body offers 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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: GFR400-10 filter regulator and GL400-10 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 GFC400-10 Combination Unit (GFC40010MNK) Is Used
Clamping fixture circuit
Prepares air for a machining-centre clamping fixture, with the check valve helping the circuit keep its conditioned state if shop supply pressure drops.
Paint shop air header
Filters, regulates and lubricates the air feeding spray-booth actuation on an automotive paint line, with manual draining tied into the end-of-shift routine.
Process valve actuation skid
Conditions the supply to pneumatic quarter-turn valve actuators on a water treatment skid, where the manual drain suits a supervised plant round.
Is the AirTAC GFC400-10 Combination Unit (GFC40010MNK) the Right Set?
Match the 400 size and its PT3/8 ports to the port size and air demand of your line; stepping to 300 or 600 changes both port and flow capacity. This version carries the K option - a reverse (check) valve - for circuits where you want to hold upstream condition if supply pressure is lost. The drain is manual, with automatic and differential-pressure drain versions available, and the filter element is the standard 40 um grade (a 5 um W option exists). Threads can be ordered as PT (standard), G (BSPP) or NPT. Flow is published as curves, not a single rated number, so ask us to confirm sizing before you order.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" 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 0.05 - 0.9 MPa (7 - 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 GFR400-10 filter regulator on its own.
AirTAC GFC400-10 Combination Unit (GFC40010MNK) FAQ
AirTAC publishes G-series flow as performance curves rather than a single rated figure, so no single number is quoted here. Send us your air demand and we will confirm the datasheet flow figures for the 400 size with PT3/8 ports on request.
K is the reverse (check) valve option on the regulator side of the set. If you do not need a check valve, the same two-unit configuration without the K suffix is the GFC40010MN, and all other decode points - PT3/8 ports, manual drain, 40 um element, no gauge - stay the same.
