The AirTAC GC40015MLF2W AirTAC F.R.L. 1/2 in, 5 um, Manual Drain is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 5 µm element, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi).
The AirTAC GC40015MLF2W is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one GC400 unit. This configuration is the 400 size with a PT1/2 port, a manual-drain filter bowl fitted with the finer 5 um element (code W), a low-pressure type regulator, and an embedded square gauge reading in psi. The polycarbonate bowls let you see condensate and oil level at a glance, and the mounting bracket is included.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600, with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus choices of drain type, filter grade, gauge scale and bracket. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

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 combination has no separate bracket code — the three 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. Constituent units, orderable separately as spares: GF400-15 filter, GR400-15 regulator and GL400-15 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds filtered, regulated and lubricated air to the clamp, pusher and seal cylinders on a carton-forming packaging machine, with the 5 um element protecting the directional valves from particulate and the lubricator keeping the cylinder seals working smoothly.
Mounted at the drop of a robotic welding cell, the unit conditions the air feeding grippers and clamps: water and 5 um filtration for the valves, low-pressure regulation matched to the cell's working pressure, and oil mist for the air tools used at the same station.
Supplies conditioned air to the pneumatic clamps and tool-change cylinders on a CNC machining centre, where the square psi gauge gives the operator a direct pressure readout, the manual drain is emptied during shift checks, and the bracket fixes the set beside the machine's air inlet.
Start with the size and port: the 400 size steps up to a 1/2 in PT port, and larger sizes carry more flow, so match the step to the air demand of the circuit. Because flow is published as curves and not a single rated figure, ask us to confirm sizing against your application before ordering. From there the real choices are: drain type (manual here; automatic and differential-pressure are available), filter grade (5 um as on this unit, or the 40 um standard), gauge scale (psi on this unit; MPa and bar scales exist), and thread (PT standard, G or NPT to order). Note this unit is the low-pressure regulator type, so choose it for circuits that run at lower working pressures. A bracket is included. If you only need filtration plus regulation, a GFR filter-regulator covers it; the GC three-unit set adds the lubricator for a complete F.R.L.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a l/min or SCFM figure. Send us your application details and we will confirm the flow figures from the datasheet and check the 400 size against your demand before you order.
The manual drain means an operator opens the bowl drain during routine checks instead of relying on automatic or differential-pressure action - a good fit where the unit is inspected regularly. The 5 um element (code W) is the finer option over the 40 um standard, chosen when downstream valves and cylinders need cleaner air. Both choices are decodable from the model code.
