The AirTAC GFR600C20MLJF3WT AirTAC Filter Regulator NPT 3/4 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 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 GFR600C20MLJF3WT is an AirTAC GFR-series filter regulator: a 5 um filter element and a pressure regulator combined in one body, size 600 with a 3/4 in NPT port. This configuration is the low-pressure regulator type with a manual drain, a 5 um (code W) element in place of the standard 40 um, an embedded square gauge scaled in bar, an aluminium alloy bowl, and no mounting bracket or reverse/check valve. Water and particulate are separated into the bowl while the regulator holds a stable downstream pressure for the circuit.
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, and options for G (BSPP) or NPT thread, automatic, manual or differential-pressure drains, 40 um or 5 um elements, gauge scale, bracket and check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

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.

Clean, regulated air to clamp cylinders on a CNC fixture, where the operator sets a lower working pressure to hold parts without crushing them and the 5 um element protects the clamp valves.
Feeding positioners and pilot solenoids on actuated process valves, with the regulator holding a low set pressure and the 5 um element keeping fine orifices clear of scale and rust.
Regulated low-pressure air for blowing dust and debris off cartons on a packaging conveyor, where gentler pressure protects lightweight packs and the manual drain is emptied at shift checks.
Size the unit by the port and flow step: 600 is the largest GFR size, here with a 3/4 in NPT port; step down to 200, 300 or 400 if your circuit draws less air. The 5 um element (code W) suits circuits with finer valves, instruments or sensitive components; choose the standard 40 um where coarser protection is enough. The manual drain means an operator opens the drain periodically to empty the bowl; automatic and differential-pressure drains are available as code options for unattended drainage. The embedded square gauge is scaled in bar; MPa and psi scales, and an external round gauge, are alternatives. Thread is NPT on this unit; PT is the standard and G (BSPP) is also an order option. A bracket can be ordered - this unit is supplied without one. The regulator is the low-pressure type; its exact adjustment range is not published, so confirm it with us. Flow is published as curves, not a single rating - ask us to confirm sizing 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the flow from the GFR600 datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits set below standard working pressures; its exact adjustment range is not published, so confirm it with us. The M marks a manual drain: open the drain at the bottom of the aluminium bowl periodically to empty collected water, or order the automatic or differential-pressure drain code if you want unattended drainage.
