AirTAC GFC400-15 Combination Unit (GFC40015LC1)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015LC1) 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 differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015LC1)
GFC40015LC1 is a genuine AirTAC G-series two-unit air-treatment set: a filter-regulator and a lubricator supplied as one matched pair, so a single order covers water and particulate removal, pressure regulation and oil-mist lubrication of a compressed-air line. This size 400 unit is threaded PT1/2 (1/2 in), carries the standard 40 um filter element and a differential-pressure drain, and is built on the low-pressure (L) regulator type. A round external pressure gauge on the MPa scale is included. Both bowls on this 400 size are PC (polycarbonate). Max working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing); the medium is compressed air only.
This is a genuine AirTAC part sold through our US distribution. The GFC two-unit series spans sizes 200, 300, 400 and 600, with drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) filtration, gauge scales in MPa, psi or bar, and G (BSPP) or NPT thread options. AirTAC publishes flow for these units as curves rather than a single rated figure, so we confirm the flow and datasheet figures 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.

| GFC400 | G-series two-unit set, 400 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |

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 (GFC40015LC1) Is Used
CNC machining centre air preparation
Conditions the supply feeding tool-clamp and pallet-changer cylinders on a CNC machining centre: water and chips-scale particulate removed, pressure held steady at the set point, and oil mist carried to the actuators.
Cartoning line valve supply
Serves as the treatment point ahead of directional control valves on a carton-forming and sealing line, keeping condensate and 40 um-scale dirt out of the valve stack while the regulator holds line pressure for consistent jaw action.
Assembly bench tool drop
Fitted at the air drop serving impact wrenches and nutrunners on an assembly bench, where the lubricator keeps tool motors oiled and the regulator caps supply pressure to the rated working pressure of the tools.
Is the AirTAC GFC400-15 Combination Unit (GFC40015LC1) the Right Set?
Size 400 with PT1/2 ports sits toward the larger end of the G-series range; step down to 300 or up to 600 when your machine's port or pipe size calls for it. Drain options are the differential-pressure drain fitted here, automatic (A) for unattended condensate removal, or manual (M). The 40 um element suits general machine air; choose the W option for 5 um where downstream valves and cylinders are more sensitive. Gauge choices are the round external gauge in MPa fitted here, the embedded square gauge, psi or bar scales, or no gauge. This code is the low-pressure (L) regulator type; its setting range is specific to that type and we confirm the exact figures on request. Thread is PT as standard, with G (BSPP) or NPT available to order. AirTAC publishes flow as curves rather than a single rating, so ask us to confirm sizing against your application before ordering.
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 (GFC40015LC1) FAQ
AirTAC publishes flow for the G series as capacity curves rather than one rated figure, so we do not quote a single number here. Tell us your working pressure and air demand and we will confirm the flow and datasheet figures for this exact unit on request.
The L selects AirTAC's low-pressure regulator type in place of the standard type, and that type carries its own setting range, which we confirm on request. Everything else decodes the same: PT1/2 ports, 40 um element, differential-pressure drain and the included MPa round gauge.
