The AirTAC GFR30015LF2WGK AirTAC Filter Regulator G1/2 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 GFR30015LF2WGK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air through a 5 um element and regulates downstream pressure. This configuration is the low-pressure type (code L), intended for circuits that run below standard line pressure. It has a G1/2 (BSPP) port, a 5 um filter grade (code W), a differential-pressure drain on the PC (polycarbonate) bowl, an embedded square gauge reading in psi, a fitted reverse/check valve (code K), and the mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um filtration, standard or low-pressure regulation, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so send us your application and we will confirm the figures from the datasheet before you order.

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.

| 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.

On a welding or assembly fixture that runs its clamps below standard line pressure, this unit filters the supply to 5 um to protect directional valves and regulates the reduced working pressure, with the fitted check valve covering back-flow protection at the station.
A paint or coating line needs clean, moisture-free air at a controlled reduced pressure for spray guns and atomizing air. The 5 um element keeps particulate out of the finish, and the low-pressure regulator type matches circuits that operate below standard plant pressure.
On a carton-sealing or labelling conveyor, this unit conditions the air feeding cylinders and low-pressure blow-off nozzles: water and 5 um-grade particulate are drained off before they reach the valves, and downstream pressure is set at the machine rather than at the compressor room.
Size and port step up with air demand: this unit is size 300 with a G1/2 port, and smaller 200 or larger 400/600 bodies exist if your line needs less or more air. The 5 um element (code W) suits instrument air, valves and coating work; the 40 um standard element is enough for general plant air. Drain is differential-pressure here; automatic (A) or manual (M) versions are available. The square gauge reads psi, with MPa and bar scales as options and an external round gauge available. Thread is G (BSPP); PT and NPT are catalogue options to order. Bracket included. Because AirTAC publishes flow as curves, not a single rated figure, ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR300 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm suitability from the datasheet before you order.
L marks the low-pressure regulator type, intended for circuits that run below standard line pressure. The exact setpoint range for this version is not published in the standard table, so we confirm it from the datasheet on request. The standard (non-L) GFR versions carry the published adjustment range.
