The AirTAC GFR600-20 AirTAC Filter Regulator 3/4 in PT, 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 PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit carries a 3/4 in PT port, a manual drain bowl in aluminium alloy, a 5 um filter element (the finer of the two catalogue grades), a round pressure gauge scaled in psi, and a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. A mounting bracket is included.
This is a genuine AirTAC part. The GFR filter-regulator line 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 filtration, gauge and scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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 0.05 - 0.9 MPa (7 - 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.

A 3/4 in filtered-and-regulated supply feeding paint booth atomizers, where the 5 um element protects finish quality and the manual drain is emptied at the start of each shift.
Conditioning and regulating the plant air feeding palletizer gripper and clamp cylinders on a high-cycle packaging line, with the round psi gauge letting operators verify set pressure at a glance.
Supplying filtered, regulated air to fixture clamps on a CNC machining cell, where stable downstream pressure keeps clamping force consistent part to part.
Start with the port step: this 600-size unit takes a 3/4 in PT port, the largest in the GFR line, so size up from 200/300/400 when your line runs larger piping and higher air demand. Choose the drain to match attendance: manual drain (this model) needs someone to open it periodically, automatic drain handles condensate unattended, and differential-pressure drain is the catalogue default. Choose 40 um for general protection or 5 um (this model, code W) where finer particulate removal matters. Gauge options are an embedded square gauge or an external round gauge, with MPa, psi or bar scales - this unit carries a round psi gauge. PT is the standard thread; G (BSPP) and NPT are order options. A mounting bracket is included on this model.
One honest note on sizing: AirTAC publishes flow for this line as curves, not as a single rated number, so we cannot quote you a rated flow figure. Send us your application details and we will confirm the datasheet flow curves against your requirement before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. 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 line as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and required flow, and we will confirm the datasheet curve figures for this 3/4 in unit on request before you order.
Manual drain means an operator opens the drain to expel collected condensate, which suits attended cells or lines already checked each shift. If the unit sits in an unattended location, choose the automatic drain variant so condensate is discharged without intervention; differential-pressure drain is the catalogue default. This model, GFR60020MC2W, is the manual-drain version.
