The AirTAC GFR600C20MJF2GK AirTAC Filter Regulator G3/4, Manual Drain 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 GFR600C20MJF2GK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single GFR600 body. This configuration is the size 600 unit with G3/4 (BSPP) ports, a manual drain bowl in aluminium alloy, the standard 40 um filter element, an embedded square gauge reading in psi, and a reverse/check valve fitted. The manual drain means an operator opens the drain at the bottom of the bowl to discharge collected condensate, and the check valve holds downstream pressure if the upstream supply is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with manual drain is 0.05-0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and is available with automatic, manual or differential-pressure drains, a 5 um element (code W) in place of the standard 40 um, gauge scale choices, G or NPT threads as order options, and with or without a mounting bracket. 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.

At a 3/4 in main air drop feeding paint booths and spray guns on an automotive assembly line, this filter regulator cleans the supply of water and pipe scale and holds a steady set pressure so atomising air stays consistent through the shift. The manual drain suits booths that are checked at the start of each shift.
On a bottling or carton-packing conveyor line running large pneumatic cylinders and grippers from a 3/4 in header, this unit filters the plant air and regulates it to the pressure the machine builder specified, while the fitted check valve keeps actuators from sagging if the upstream supply drops.
In a water-treatment or chemical process plant where large pneumatic quarter-turn valves are actuated from a 3/4 in instrument-air branch, this filter regulator delivers clean, regulated air to the positioners and actuators, with the psi gauge giving operators a local reading at the panel.
Start with the size and port: this is the largest GFR size (600) with 3/4 in ports, chosen when your line needs the higher flow capacity of the big frame - we can confirm the flow curve against your demand before you order. Drain type is a real decision: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl regularly; choose automatic drain if the unit sits where nobody routinely passes. Filter grade is the standard 40 um, adequate for general actuation and air tools; specify the 5 um W element if downstream equipment needs finer filtration. The gauge here is the embedded square type reading psi (MPa and bar scales are alternatives, and an external round gauge is optional). Thread is G (BSPP); PT is the catalogue standard and NPT is an order option. A mounting bracket is not included with this code (J). Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 we do not quote a rated flow number. Tell us your line pressure, set pressure and air demand, and we will confirm the flow curve and sizing from the datasheet for you before you order.
The M in the code specifies a manual drain: condensate collected in the aluminium bowl is discharged by opening the drain by hand. It suits installations that are visited regularly, such as a maintained compressor room or a machine checked each shift. If the unit will sit unattended, ask us about the same GFR600 unit with an automatic or differential-pressure drain instead.
