The AirTAC GFR600C20MJF1T 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 AirTAC GFR600C20MJF1T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, a manual drain bowl in aluminium alloy (size 600 bowls are metal, not polycarbonate), a 40 um standard filter element, and an embedded square gauge scaled in MPa. The standard-type regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, PT as the standard thread and G or NPT as order options, with a choice of drain type, 40 um or 5 um (W) filtration, gauge scale, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 feeding tool-change cylinders and clamping fixtures on a machining centre, with the square gauge letting operators verify set pressure at the machine.

Size and port drive the choice: the 600 body with a 3/4 in port suits the upper end of the GFR flow range, but because flow is published as curves rather than a single rating, ask us to confirm sizing against your air demand before ordering. Drain type is a real decision: this unit has a manual drain, which needs periodic draining by hand; automatic and differential-pressure drains are available in the family if you want condensate handled without operator attention. Filtration is 40 um standard here, with 5 um (code W) available where finer protection is needed. The embedded square gauge is fitted with an MPa scale; psi and bar scales and an external round gauge are options. Thread is NPT on this unit (PT is the standard, G and NPT are catalogue options), and the J code means no mounting bracket is supplied - order a bracket 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 GFR series as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote. Tell us your application and required flow, and we will confirm the figures from the datasheet on request before you order.
The M code in GFR600C20MJF1T specifies a manual drain bowl: condensate collects in the aluminium bowl and is drained by hand, which suits attended installations. If you want condensate removed without operator action, the family also offers automatic (A) and differential-pressure (blank) drain versions - ask us to quote the equivalent code.
