The AirTAC GFR600C20MJF1TK 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 GFR600 is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body, so one 3/4 in NPT connection does both jobs. This configuration carries the standard 40 um filter element, a manual drain you operate by hand to empty the bowl, a regulator with a 0.05-0.9 MPa (7-130 psi) adjustment range, an embedded square gauge scaled in MPa, and a built-in reverse/check valve that holds the setting if upstream supply is interrupted. The size 600 bowl is aluminium alloy, and the unit is rated to 1.0 MPa (145 psi) inlet and -5 to 70 C (non-freezing). No mounting bracket is included with this code.
This is a genuine AirTAC part, supplied by an authorised distributor. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads, drain types, 40 um or 5 um filtration, gauge styles and scales. Flow figures are published as curves rather than a single rating, 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.

Dropping off a 3/4 in main to feed a packaging hall's supply line: the GFR600 strips water and pipe scale at the 40 um grade, sets a stable working pressure for the whole drop, and the manual drain lets maintenance empty the aluminium bowl during their shift walk.
Feeding a pneumatic press or clamping station where the check valve keeps the set pressure held at the machine if the upstream supply dips, while the regulator holds the force setting the tooling was validated at.
Positioned upstream of a manifold feeding several actuators and air tools on a fabrication line: one 3/4 in filter regulator conditions and regulates the whole branch, with the MPa gauge giving operators a single point to verify supply pressure.
Size 600 with a 3/4 in port sits at the top of the GFR range, so step up to it when your line's flow demand outgrows a 1/2 in unit - and ask us to confirm the flow curve against your consumption before ordering, since AirTAC publishes flow as curves, not a single rated number. Drain choice matters: this code has a manual drain, which suits installations where someone checks the bowl as part of a routine; choose automatic or differential-pressure drain codes if the unit will be left unattended. The 40 um element is the standard grade for general plant air; the 5 um (W) option is there when downstream equipment needs finer filtration. The embedded square gauge is scaled in MPa; psi and bar scales and an external round gauge are available on other codes. Thread is NPT on this unit, with PT and G (BSPP) as orderable options, and this code ships without a mounting bracket - add a bracket code if you want panel or wall fixing.
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 GFR600 as performance curves rather than a single rated figure, so we do not quote a number here. Tell us your operating pressure and air consumption and we will confirm the datasheet flow figures for this exact 3/4 in NPT configuration on request before you order.
The M in the code means the aluminium bowl is emptied by hand, which suits stations that are checked regularly. If the unit will sit unattended, the automatic (A) or differential-pressure (blank) drain codes in the same GFR600 series discharge condensate without operator action - the regulation range also differs slightly by drain type, so ask us to confirm the right code for your setup.
