The AirTAC GFR40015LJC2W AirTAC Filter Regulator PT1/2, 5 um is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1/2" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR40015LJC2W is a filter regulator: it removes water and particulate from compressed air and controls downstream pressure in a single body. This size 400 unit is built with a PT1/2 (1/2 in) PT-thread port, a 5 um filter element for finer filtration than the 40 um standard, a differential-pressure drain that bleeds condensate automatically as flow passes through, and a round pressure gauge reading in psi. It is the low-pressure type, and no mounting bracket is included.
This is a genuine AirTAC part in the GFR400 series, one of four sizes (200/300/400/600) with ports from 1/8 in to 1 in and thread options of PT (standard), G and NPT. Drain types, filter grades, gauge styles and scales are all orderable options. Flow figures are published as curves rather than a single rating, so ask us and we will confirm the datasheet numbers 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. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Mounted ahead of a bench pneumatic press, the GFR40015LJC2W cleans the shop air to 5 um and holds a steady low regulated pressure to the press cylinder, with the psi gauge giving the operator a direct setting reference.
On a carton-sealing or wrapping line running continuous shifts, the differential-pressure drain sheds condensate as air flows, keeping water out of the line's valves and actuators while the regulator keeps drive pressure consistent.
Feeding the valve manifold of a pick-and-place robot, this unit filters fine particulate that would score spool surfaces and regulates supply pressure to the gripper circuit, all through a single PT1/2 connection.
Start with the port step: size 400 carries a PT1/2 (1/2 in) connection, so step up or down a size if your line needs a different port or more flow capacity. For drainage, the differential-pressure drain on this unit suits steady flowing lines; choose automatic (code A) for idle lines that still collect condensate, or manual (code M) where you want scheduled draining. This unit carries the 5 um element (code W); the 40 um standard grade is the usual choice for general plant air, with 5 um reserved for finer protection downstream. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. PT is the standard thread, with G and NPT available as order options, and brackets can be added if this no-bracket configuration needs panel fixing.
One honest note before you order: filter-regulator flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you commit.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR400 series as curves, not as a single rated number, so there is no one flow figure we can honestly quote. Send us your line conditions and required flow, and we will confirm the sizing against the datasheet on request before you order.
The W in the code sets the 5 um filter grade instead of the 40 um standard, giving finer protection for sensitive downstream equipment, and C2 sets the round external gauge with a psi scale (MPa and bar scales are also available). The unit is also the low-pressure type, so it is intended for circuits regulated well below standard plant pressures.
