The AirTAC AirTAC GFR20008JF2GK Filter Regulator G1/4 (1/4 in) is a genuine G-series filter regulator: water separation, 40 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 GFR20008JF2GK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 200-size unit has a G1/4 (1/4 in) G-thread port, a 40 um standard filter element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element rises. Downstream pressure is set across the standard regulation range of 0.15-0.9 MPa (20-130 psi), read on the fitted embedded square gauge scaled in psi, and the built-in reverse/check valve holds the setting if upstream supply is lost.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, optional 5 um (W) elements, automatic or manual drains, MPa/psi/bar gauge scales, and G or NPT thread options. Rated flow is published only as catalogue curves rather than a single figure, so ask us to confirm sizing and 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

Filter, regulate and check-hold the air feeding solenoid valves and clamping cylinders on a CNC machining centre, with the psi square gauge giving operators a local setpoint readout.
Condition and set pressure for the air cylinders that stop, push and divert packs on a bottling or cartoning conveyor, with the check valve holding the setting through supply dips.
Feed clean, regulated air to gripper and vacuum-generator circuits on a robotic pick-and-place cell, using the differential-pressure drain to keep condensate off the downstream components.
Start with port size: this unit is 200 size with a G1/4 (1/4 in) G-thread port; step up to 300/400/600 if your line needs more flow capacity. Choose the drain: this configuration uses the differential-pressure drain (default); automatic (A) or manual (M) drains are orderable. The 40 um element suits general plant air; specify the 5 um (W) grade where finer filtration is needed. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are options. G-thread is as coded here, with PT (standard) and NPT available to order. Note this unit ships without a mounting bracket (J). Flow for this family is published as curves, not a single rated number, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this family as catalogue curves rather than a single rated figure, so no rated flow, Cv or SCFM number can be quoted here. Send us your line pressure, downstream demand and application details and we will confirm the sizing from the datasheet on request.
K means a reverse/check valve is fitted, so the regulated downstream pressure is held if the upstream supply is interrupted. This unit uses the differential-pressure drain, which automatically discharges collected condensate as the pressure differential across the 40 um element rises; automatic (A) and manual (M) drain versions are available to order.
