AirTAC GFC400-15 Combination Unit (GFC40015LF1)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015LF1) 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 (GFC40015LF1)
GFC40015LF1 is a genuine AirTAC G-series two-unit air-treatment set: a filter-regulator and a lubricator supplied as one matched pair, so one order covers filtration, 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. The F1 code fits the embedded square pressure gauge on the MPa scale. 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.

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 (GFC40015LF1) Is Used
Trailer air system service points
Used at workshop supply stations serving trailer and body pneumatic equipment, where the set filters road-dust-laden shop air, holds a stable regulated pressure and mists oil into the supply for gate and lift cylinders.
Panel-mounted machine valve stack
Mounted ahead of the valve stack in a machine's pneumatic panel, with the embedded square MPa gauge readable at the panel face so operators can verify regulated pressure without opening the enclosure.
Packaging machine clutch-brake supply
Conditions and regulates the air feeding clutch-brake units on packaging machinery, where steady pressure and clean, lubricated supply keep engagement consistent across shifts.
Is the AirTAC GFC400-15 Combination Unit (GFC40015LF1) the Right Set?
Size 400 with PT1/2 ports sits toward the larger end of the G-series range; move to 300 or 600 when your machine's ports or piping call for it. Drain options are the differential-pressure drain fitted here, automatic (A) for unattended removal, or manual (M). The 40 um element suits general machine air; the W option gives 5 um where needed. Gauge choices are the embedded square gauge in MPa fitted here, the round external 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 (GFC40015LF1) FAQ
AirTAC publishes flow for the G series as capacity curves rather than a single rated figure, so we do not quote one number here. Give us your working pressure and air demand and we will confirm the flow and datasheet figures for this unit on request.
F1 selects the embedded square pressure gauge on the MPa scale, fitted as part of the set. The alternative in this family is the round external gauge (C) in MPa, psi or bar scales, or no gauge at all. GFC40015LF1 pairs that square gauge with the PT1/2, 40 um, low-pressure configuration.
