AirTAC GFC400-15 Combination Unit (GFC40015F1)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015F1) 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 (GFC40015F1)
GFC40015F1 is an AirTAC G-series two-unit air treatment set: a filter regulator and a lubricator paired as one 2-piece combination. This size 400 unit has 1/2 in PT ports, a 40 um filter element and a differential-pressure drain on the filter bowl. The regulator adjusts from 0.15-0.9 MPa (20-130 psi) and the embedded square gauge reads in MPa. Bowls on the 400 size are PC (polycarbonate); maximum 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. The G series runs from size 200 to 600 with ports from 1/8 to 1 in, plus catalogue options for drain type (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge style and scale, and G (BSPP) or NPT threads. Flow for the series is published as curves rather than a single rating, so we confirm the 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. 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 (GFC40015F1) Is Used
Food-packaging conveyor drives
Supplies the pneumatic belt-tension and gate cylinders on a packaging conveyor, with 40 um filtration and lubricated air delivered from one treatment point.
Maintenance workshop tool drops
Serves a 1/2 in air-tool drop in a plant maintenance workshop; the lubricator oils the impact wrenches and grinders run from the same leg.
Water plant gate actuators
Provides treated air to the quarter-turn gate and sluice actuators at a water treatment plant, with the MPa square gauge for local setpoint adjustment.
Is the AirTAC GFC400-15 Combination Unit (GFC40015F1) the Right Set?
Size 400 with PT1/2 ports sits in the upper half of the G range (sizes 200 to 600, ports 1/8 to 1 in); step sizes if your piping and demand call for it. Drain type on the filter bowl is differential-pressure here (the default); automatic (A) and manual (M) versions are available. Filtration is 40 um standard; the W code selects 5 um. Gauge: this unit is coded F1, the embedded square gauge with an MPa scale; C codes select the optional external round gauge, with 1 = MPa, 2 = psi and 3 = bar. Thread is PT as standard, with G (BSPP) and NPT as catalogue options. 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 (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 (GFC40015F1) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not state a number here. Share your application pressure and demand and we will confirm the flow and datasheet figures for this 1/2 in unit on request before you order.
F1 is the embedded square gauge with an MPa scale. C codes select the optional external round gauge, where 1 = MPa, 2 = psi and 3 = bar. This unit is coded F1 - square gauge, MPa scale - and the gauge choice does not affect the filter grade or drain type.
