AirTAC GFC400-15 Combination Unit (GFC40015AF1)
The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015AF1) 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 automatic drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GFC400-15 Combination Unit (GFC40015AF1)
GFC40015AF1 is a two-unit G-series air preparation set from AirTAC, combining a filter-regulator with a lubricator so one assembly filters, regulates and lubricates the compressed air supply. This version is size 400 with PT1/2 ports, an automatic drain on the filter bowl, the standard 40 um filter element and the square embedded gauge scaled in MPa.
This is a genuine AirTAC part. The G-series ranges across sizes 200, 300, 400 and 600, with drain type, 40 um or 5 um filtration, gauge style and scale, and PT, G or NPT threads as catalogue options. Flow is stated as curves rather than a single figure, so datasheet values are confirmed 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 (GFC40015AF1) Is Used
Food processing conveyor diverters
Feeds diverter and pusher cylinders along a food handling line, delivering clean, regulated, lubricated air with the automatic drain coping with washdown-area condensate.
Palletizer layer grippers
Conditions the supply to gripper and clamp actuators on a palletizing cell, where stable regulated pressure keeps layer forming repeatable through each cycle.
Maintenance shop air tools
Prepares air at a maintenance drop for impact wrenches, chisels and grinders, with the lubricator feeding tool motors and the automatic drain protecting the circuit.
Is the AirTAC GFC400-15 Combination Unit (GFC40015AF1) the Right Set?
Choose size 400 with PT1/2 when the port and flow of your circuit call for it, and step to 200, 300 or 600 where smaller or larger lines apply. The automatic drain suits unattended duty; manual and differential-pressure drains are the other decodable options. Keep the standard 40 um element for general plant air, or order the 5 um W grade where finer filtration matters. The square embedded gauge here reads MPa.
PT is the standard thread, with G (BSPP) and NPT available as orderable specifications. Because flow is published only as curves, ask us to confirm sizing against your application before you order.
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 (GFC40015AF1) FAQ
Not as a single number, because AirTAC publishes G-series flow as characteristic curves rather than one rated figure. Send us your operating pressure and demand profile and we will confirm the sizing against the datasheet curves on request.
F1 specifies the square embedded gauge scaled in MPa. Alternatives for this set are a round external gauge in psi (C2) or bar (C3), so pick the suffix that matches how your plant reads pressure.
