The AirTAC AirTAC GFC400-15 Combination Unit (GFC40015F3W) 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 5 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC40015F3W 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 finer 5 um filtration element selected by the W code, and a polycarbonate filter bowl with the standard differential-pressure drain. 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.
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.

Conditions half-inch air to weld-gun clamping and torch-clean actuators on a robotic welding cell, with 5 um air protecting the pilot valves.
Feeds screwdriver and clamp tooling at electronics assembly benches, using 5 um filtration ahead of sensitive pneumatic components.
Supplies regulated, lubricated air to cylinder-driven test fixtures in an R&D or QA lab, with bar-scale gauges matching the rig instrumentation.
Size 400 with PT1/2 ports suits heavier half-inch circuits; choose 600 for more flow or 300 for lighter demand. The differential-pressure drain is standard here, with automatic (A) or manual (M) codes available for intermittently running lines. The W code fits the 5 um element for finer protection versus the standard 40 um grade, and the F3 square gauge reads in bar. Thread is PT as standard; G (BSPP) and NPT versions are catalogue options to order. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
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.
Yes. AirTAC publishes flow for the G series as curves rather than a single rated number, so we confirm sizing from the datasheet on request. Send your working pressure and required demand and we will check the fit before you order.
The GFC series combines a filter regulator and a lubricator in two pieces, as here. The GC series is the three-piece arrangement with separate filter, regulator and lubricator bodies. Function is the same trio of jobs; the choice comes down to layout and maintenance preference.
