The AirTAC GFR20008F2K AirTAC Filter Regulator 1/4 in PT, 40 um 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 GFR20008F2K is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one compact body. This 200-size unit is threaded PT 1/4 in and carries the standard 40 um filter element, suited to general plant air. The differential-pressure drain bleeds collected condensate automatically whenever the pressure differential across the element is high enough, so no manual draining routine is needed. The fitted square gauge reads in psi, and the built-in reverse (check) valve holds downstream pressure if the upstream supply is lost.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (W) filtration, square or round gauges in MPa, psi or bar scales, and G or NPT thread options. Flow is published as curves rather than a single rating, so ask us to confirm the figures 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. 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.

Feeds and regulates the clamp cylinders on a CNC fixture, with the check valve holding clamp pressure if the main supply drops mid-cycle.
Conditions plant air ahead of the directional valves on a carton-sealing line, keeping water and scale out of the valve seats at a set working pressure.
A filtered, regulated branch feeding panel-mounted regulators and solenoid valves, with the psi gauge giving operators a local pressure readout.
Start with the port step: this unit is 1/4 in PT in size 200; step up to sizes 300, 400 or 600 for larger ports and higher air demand. Choose the drain to match maintenance practice - differential-pressure (this unit, drain-free in normal service), automatic, or manual where you want a deliberate drain point. The standard element is 40 um; specify the W suffix for 5 um where finer protection is needed. Gauges are square (fitted here, psi scale) or optional external round, with MPa, psi and bar scales available; thread is PT as standard with G (BSPP) and NPT as orderable options, and a mounting bracket is included.
Flow for this family is published as curves, not a single rated figure, so send us your air demand and line conditions 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 the GFR family as curves, not as a single rated number, so we do not quote a figure here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request before you order.
K means a reverse (check) valve is fitted, so downstream pressure is held if the upstream supply fails. This unit has no drain letter, which is the differential-pressure drain: condensate is expelled automatically when the pressure differential across the 40 um element rises, with no manual draining required. Automatic (A) and manual (M) drains are available as options.
