The AirTAC GFR20008LJF3WTK AirTAC Filter Regulator 1/4 in NPT 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 PT1/4" 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 GFR200 series combines water and particulate filtration with pressure regulation in a single body, so one 1/4 in ported unit both cleans the air and sets the downstream pressure. This configuration, GFR20008LJF3WTK, is specified with 5 um filtration (code W) for finer particle removal than the standard 40 um element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, a low-pressure regulator type for circuits set below standard working pressures, an embedded square gauge scaled in bar, and a reverse/check valve that holds the downstream setting when the supply is removed. It is supplied without a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The polycarbonate bowl suits the 200 size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filter grades, standard or low-pressure regulator types, gauge and thread options, and bracket choices. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

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.

Fill and capping heads on a bottling line often run at reduced settings; this low-pressure type filter regulator cleans the supply, holds the set pressure via the reverse/check valve, and shows the setting on the bar-scale gauge.
Pneumatic workholding clamps need clean, moisture-reduced air at a stable set pressure; the 5 um element protects the clamp cylinders and the regulator keeps gripping force consistent across the shift.
Sorting diverters cycle continuously and are sensitive to water and fine debris; this unit filters to 5 um, regulates the actuator supply, and its differential-pressure drain handles condensate without operator attention.
Start with the port and size: this unit is the 200 size with 1/4 in NPT ports; larger 300, 400 and 600 sizes step up both port and flow capacity, so match the size to the air demand of the circuit rather than oversizing on guesswork. Choose the drain to suit access: differential-pressure (as fitted here) needs no attention during operation, automatic drains continuously, and manual suits supervised points. Choose the filter grade against the sensitivity of downstream equipment: 40 um is the standard element and 5 um (this unit, code W) suits finer protection. The embedded square gauge here reads in bar; MPa and psi scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT (this unit) as order options, and brackets are optional - this configuration omits it. Flow is published as curves, not a single rating, so 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 flow for the GFR200 series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the datasheet and check the sizing against your required flow before you order.
W is the filter grade code: it fits the 5 um element in place of the standard 40 um element. Choose 5 um where downstream valves, cylinders or instruments need finer protection from particles; choose 40 um for general-purpose supply where coarser removal is sufficient. This unit is factory-configured with the 5 um element.
