The AirTAC GFR30010LJF2WG AirTAC Filter Regulator G3/8, 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 PT3/8" 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 GFR30010LJF2WG is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration is built with a G3/8 (BSPP) port, a 5 um filter element (code W, versus the 40 um standard), a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element rises, and a low-pressure regulator type for circuits set well below standard working pressures. The embedded square gauge reads in psi, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional), gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |

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.

On a fixture-clamping manifold run well below standard line pressure, this low-pressure type filter regulator cleans the supply and holds the reduced setting, with the psi gauge giving the operator a direct readout at the setpoint.
Feeding a machining centre's pneumatic valves and actuators, the 5 um element strips water and fine particulate ahead of the regulated supply, and the differential-pressure drain clears condensate without daily manual attention.
On a packaging conveyor with cylinders and air-driven diverters, this combined filter regulator conditions the air and sets the working pressure in one body, saving panel space over separate filter and regulator units.
Size and port set the flow path: this unit is size 300 with a G3/8 port, one step up from 1/4 in and one below 1/2 in - match it to the line size and demand of the circuit rather than oversizing on guesswork. The 5 um element (W) suits applications that need finer particulate capture than the 40 um standard; the differential-pressure drain is the default and needs no operator action, while automatic and manual drains are orderable alternatives. The square gauge here reads psi; MPa and bar scales are also available. Thread is G (BSPP) - PT is the catalogue standard and NPT is an orderable option - and a mounting bracket can be added if this J (no bracket) version does not suit the panel. Flow for this family is published as curves, not a single rating, so send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR series as curves, not as a single rated figure, so we do not quote a number. Send us your line size and air demand and we will confirm the flow curve and sizing from the datasheet on request before you order.
The W in the code GFR30010LJF2WG selects the 5 um filter element instead of the 40 um standard, giving finer particulate capture. The drain code is blank, which means the differential-pressure drain: condensate is expelled automatically when the pressure differential across the element rises, with no operator action needed. Automatic (A) and manual (M) drains are orderable alternatives.
