The AirTAC GFR600C20MLJF3WTK AirTAC Filter Regulator NPT3/4 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 GFR600C20MLJF3WTK is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This 600-size unit has a 3/4 in NPT port, a 5 um filter element (code W, finer than the 40 um standard), a manual drain on the aluminium alloy bowl, a low-pressure type regulator, an embedded square gauge with bar scale, and a reverse/check valve fitted. No mounting bracket is included (code J). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with PT, G or NPT thread options, differential-pressure, automatic or manual drains, 40 um or 5 um elements, gauge and scale choices, and standard or low-pressure regulators. Flow is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure 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.

Point-of-use conditioning for a carton-sealing or case-packing station: the 5 um element strips water and fine particulate before the air reaches sealing cylinders and clamps, while the low-pressure regulator holds the gentler setting those actuators need.
Filtered, regulated air for quarter-turn pneumatic actuators on a water-treatment or chemical-dosing skid, where the reverse/check valve helps hold the set circuit and the manual drain supports a scheduled daily blowdown routine.
Conditioning the air feed to spray guns in a woodworking or metal-finishing booth: fine 5 um filtration reduces water and dirt in the finish, and the low-pressure regulator with bar-scale gauge lets the operator set and read the gun supply pressure.
Every letter in this code is a real choice: size 600 with a 3/4 in NPT port suits lines plumbed at that size and the higher flows of a larger header; the 5 um element (W) protects downstream equipment more finely than the 40 um standard; the manual drain (M) means an operator opens the bowl drain during routine checks instead of relying on an automatic or differential-pressure drain; the low-pressure type (L) regulator is intended for circuits working below the standard regulator's range - the exact range is not published, so confirm it with us; the square gauge reads in bar (scales MPa, psi and bar are available); and the K code adds a reverse/check valve. No bracket is included, so plan your mounting. Temperature is -5 to 70 C, non-freezing.
Because AirTAC publishes flow as curves rather than a single rated figure, we do not quote a flow number here. Send us your required flow and working pressure 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 this family as curves, not as a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request before you order.
The M code means the aluminium alloy bowl carries a manual drain: an operator opens it to expel collected water during routine checks. The GFR family also offers automatic (A) and differential-pressure (blank) drains as order options, so tell us which drain type you prefer when ordering.
