The AirTAC GFR600C20MLJNT AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR600C20MLJNT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is fitted with a 3/4 in NPT port, a manual drain and the standard 40 um filter element, and it is the low-pressure (L) regulator variant. It comes without a gauge and without a mounting bracket, and the 600-size bowl is aluminium alloy. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
GFR600C20MLJNT is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options across the family include G or NPT thread, automatic, manual or differential-pressure drain, a 5 um (W) filter element, gauge and scale choice, and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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 for the pneumatic cylinders that drive capping, labelling and reject stations on a bottling line, with the manual drain letting maintenance purge accumulated water at shift checks.
Filtered, pressure-controlled air for diverter gates, pushers and stoppers on a parcel-sort conveyor, where the 3/4 in port suits a larger header feeding several stations.
Stable, low-pressure filtered air to benchtop pneumatic instruments and test rigs, where the low-pressure regulator variant and oil-free filter-regulator function keep the supply clean and steady.
The real choices in this family are the size and port step (200/300/400/600 against the flow your line needs), the drain type (manual here; automatic and differential-pressure are available), the filter grade (40 um standard, 5 um with code W), the gauge and its scale, the thread (PT is the standard; G and NPT are catalogue options to order), and whether a bracket is fitted. This unit is the low-pressure regulator variant with no gauge and no bracket.
Because flow is published as curves rather than a single rated figure, 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 G-series flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure and air demand and we will confirm sizing against the datasheet on request.
It marks the low-pressure regulator variant of the GFR600; its exact adjustment range is not published in the catalogue, so we confirm it on request. The rest of the code decodes as: 20 = 3/4 in port, T = NPT thread, M = manual drain, 40 um standard filter element, J = no bracket, N = no gauge.
