AirTAC GFC400-15 Combination Unit (GFC40015F3)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015F3) 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 (GFC40015F3)
GFC40015F3 is an AirTAC G-series two-unit air-treatment set for compressed air: a filter regulator and a lubricator combined as one 2-piece assembly. This size 400 unit has PT1/2 ports, the standard 40 um filtration element, and a polycarbonate filter bowl with the standard differential-pressure drain that bleeds condensate as flow resumes. The regulator has an embedded square gauge reading in bar and adjusts between 0.15 and 0.9 MPa (20-130 psi); the lubricator feeds an oil mist to downstream equipment. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part supplied by a US distributor. The G series spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 5 um or 40 um filtration, gauge scales, and thread options with PT as the standard (G and NPT are catalogue options to order). Flow is published as curves rather than one rated number, so we confirm sizing and datasheet 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: GFR400-15 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 (GFC40015F3) Is Used
Workshop air tool benches
Conditions the half-inch bench drop that feeds impact wrenches, nutrunners and air ratchets in a maintenance workshop, with the regulator setting tool supply pressure.
Bottling line conveyor gates
Supplies clean, regulated, lubricated air to gate and divertor cylinders along a bottling conveyor, keeping the 40 um element ahead of directional valves.
Fleet service bay drops
Feeds lifting tables and tyre-shop tools in a commercial vehicle service bay from a half-inch ring main, with bar-scale gauges matching workshop gauges.
Is the AirTAC GFC400-15 Combination Unit (GFC40015F3) the Right Set?
Size 400 with PT1/2 ports is the mid-large step of the G series; step up to 600 for larger ports and more flow, or down to 300 for lighter demand. This unit keeps the differential-pressure drain, with automatic (A) or manual (M) drain codes available. The standard 40 um element suits general pre-filtration; add W to the code if you need the 5 um grade. The F3 square gauge reads in bar, convenient where plant instruments are bar-scaled. Thread is PT as standard; G (BSPP) and NPT versions are catalogue options to order. AirTAC publishes flow 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 (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 (GFC40015F3) FAQ
Flow for the G series is published by AirTAC as performance curves rather than a single rated figure, so we do not state one here. Share your operating pressure and demand and we will confirm sizing against the curves on request.
F is the embedded square pressure gauge and the 3 sets its scale to bar. If you prefer MPa, order the F1 variant; other scale options exist in the series. The regulator itself adjusts across the same 0.15-0.9 MPa (20-130 psi) range regardless of gauge scale.
