The AirTAC GFR600C20MJF3TK AirTAC Filter Regulator 3/4 in NPT 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 GFR600C20MJF3TK is a 600-size filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration has 3/4 in NPT ports, a manual-drain bowl in aluminium alloy, a 40 um standard filter element, an embedded square gauge scaled in bar, a built-in reverse/check valve, and no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with G (BSPP) or NPT threads, automatic, manual or differential-pressure drains, a 5 um (W) element, alternative gauge scales, and with or without a bracket. Flow for this family is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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.

Feeding case sealers, carton tapers and bagging heads from a 3/4 in drop off the main header, with the manual drain emptied during the shift-end maintenance round.
Regulating shop air before it reaches tool-change actuators, pneumatic clamps and chip-suction gates on a machining center, with the bar gauge giving operators a local setpoint readout.
Supplying filtered, regulated air to the divertor cylinders and stopper gates along a distribution conveyor, where the check valve keeps the gates in position during upstream pressure dips.
The real choices in this family are all decodable from the code. Step the size (200/300/400/600) and port (1/8 to 1 in) against the air demand of the line - larger sizes carry more flow, and we will confirm the exact curve figures on request before you order. Choose the drain: manual as here, suited to attended maintenance rounds, or automatic or differential-pressure for unattended drainage. Choose the element: 40 um standard or 5 um (W) where finer protection matters. The gauge scale is MPa, psi or bar (bar on this unit), the thread is PT as standard with G and NPT as order options (NPT on this unit), and the bracket can be included or omitted (J, as here). A reverse/check valve (K) holds downstream conditions if upstream supply is interrupted.
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 on the page. Send us your inlet pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request before you order.
The M in the code means a manual drain: condensate collected in the aluminium bowl is released by opening the drain during maintenance rounds, which suits lines that are attended regularly. The same GFR family is also available with automatic or differential-pressure drains if you prefer unattended drainage, and with a 5 um (W) element instead of the 40 um standard fitted here.
