The AirTAC GFR600C20MF2WK AirTAC Filter Regulator PT3/4, 5 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 See datasheet 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 GFR600C20MF2WK is a size 600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is fitted with a 5 um filter element (the finer of the two catalogue grades), a manual drain on the aluminium alloy bowl, an embedded square gauge reading in psi, a reverse/check valve, and a mounting bracket. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing). The port is PT3/4 (3/4 inch) with PT thread as standard.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch and a choice of drain type, filter grade, gauge scale and thread (PT standard, with G and NPT as order options). Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Installed at the 3/4 inch main drop feeding a machining cell, the unit dries and cleans the supply to 5 um and holds a set regulator pressure for the cell's air tools and clamps, with the psi gauge giving the operator a local reading.
Mounted ahead of the cylinder bank on a packaging conveyor line, the unit conditions the plant air and regulates the pressure to the drive and diverting cylinders, with the check valve holding the downstream setting if supply pressure dips.
Fitted at a setup panel for a pneumatic press, the unit lets the setter filter the incoming air to 5 um and dial in the working pressure per job on the psi gauge, with manual draining as part of the shift-start routine.
At size 600 with a 3/4 inch PT port, this is the largest GFR frame, so step up or down through the 200/300/400/600 range against the flow your line needs - we can confirm the flow curves before you order. This unit is already specified with the finer 5 um element (the 40 um standard grade is available in other codes), a manual drain (automatic and differential-pressure drains are the alternatives), a square psi gauge (MPa and bar scales exist, and an external round gauge is optional), and a reverse/check valve. Thread is PT as standard; G (BSPP) and NPT are order options, and a no-bracket version (code J) is also listed.
Because AirTAC publishes flow only as curves and not as a single rated number, we do not quote a rated flow figure here. Send us your application details and we will confirm sizing against the datasheet 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 series as curves in the catalogue, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number here. Tell us your application and we will confirm the flow and sizing figures from the datasheet on request.
The M in the code means the aluminium alloy bowl on this GFR600 is fitted with a manual drain, which an operator opens to discharge collected water. The catalogue also lists automatic and differential-pressure drain options on the GFR family, so if you prefer hands-off draining we can quote the equivalent code with the drain type you need.
