The AirTAC GFR600C20MLF2WGK AirTAC Filter Regulator G3/4, 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 GFR600C20MLF2WGK is a size-600 filter regulator: it removes water and particulate from compressed air and reduces pressure to the working level, all in a single body. This configuration carries a G3/4 port with G (BSPP) thread, a 5 um filter element (the finer of the two available grades), a manual drain on the bowl, a reverse/check valve, and an embedded square gauge reading in psi. It is the low-pressure type, intended for circuits that run below standard line pressure; the exact setting range for this variant is published in the AirTAC datasheet and we confirm it on request. The aluminium alloy bowl is standard at size 600, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and each size can be ordered with a different drain type, filter grade, gauge style and scale, thread (PT standard, G or NPT to order), reverse valve and bracket option. Rated flow is published as curves rather than a single figure, so send us your application and we will confirm the sizing and datasheet figures before you order.

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.

On a stamping or assembly press, fixture clamps often run at a set pressure below the main header. This filter regulator cleans the header air to 5 um and holds the reduced setting for the clamp circuit, with the psi gauge giving the operator a direct reading at the cell.
Conveyor stop-gates, pushers and box-flap cylinders on a packaging line need clean, regulated air at a gentle setting to avoid product damage. This unit filters water and particulate from the drop leg, regulates the branch to the set pressure, and its manual drain suits a line bled down at shift end.
A bench test rig exercising pneumatic components needs air free of water and fine particles so results are not skewed by contamination. The 5 um element conditions the supply, the low-pressure type suits rigs that run below standard shop pressure, and the reverse/check valve holds the setting if the supply dips.
Start with the port step: size 600 with a G3/4 port suits lines plumbed at 3/4 inch, and larger sizes carry more flow - match the size to the air demand of the circuit rather than the pipe alone. Choose the drain to suit access: manual drain (as here) needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate without attention. The 5 um element (code W) is the finer grade versus the 40 um standard - pick 5 um where downstream valves and instruments need cleaner air. The embedded square gauge with psi scale is standard here; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this unit; PT is the standard catalogue thread with G and NPT available to order. A reverse/check valve is fitted, and the bracket is included.
One honest note on sizing: AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we cannot quote a rated flow figure here. Ask us to confirm the curve and the low-pressure setting range for this exact variant against your application before ordering.
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 performance curves rather than a single rated figure, so we do not quote a rated flow number. Send us your application details and we will confirm the flow curve for this size-600, G3/4 unit from the datasheet, along with the setting range for the low-pressure variant, so you can size it correctly before ordering.
The bowl collects water separated from the air, and the M code in the model means it is drained by hand rather than automatically. Manual drain suits installations where the bowl is easy to reach and the line is bled routinely, such as a supervised cell or a bench. If the unit sits in an inaccessible spot or runs unattended, ask us about the automatic or differential-pressure drain versions of the same GFR600 configuration.
