The AirTAC GFR600C20MLJC2GK AirTAC Filter Regulator G3/4 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 GFR600 series is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with a G3/4 (3/4 inch) G-thread port, a 40 um standard filtration element, a manual drain on the bowl, and the low-pressure regulator type. It is supplied with a round external gauge reading in psi, a reverse/check valve fitted, and no mounting bracket. At size 600 the 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).
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Point-of-use conditioning on a 3/4 inch main feeding a pneumatic stamping or forming press: the 40 um element strips water and swarf from the shop air line while the low-pressure regulator holds a steady setting to the press cylinders.
Supplying filtered, pressure-limited air to large diaphragm or pinch valves on a treatment plant skid, where the low-pressure regulator type matches modest actuation pressures and the manual drain suits a supervised daily check routine.
Conditioning the air feed to stopper, pusher and gating cylinders on a bottling or cartoning conveyor line, with the reverse/check valve holding the downstream circuit if upstream supply is interrupted.
Start with the port step: size 600 with a G3/4 port suits lines where larger downstream demand calls for the bigger port, while 200/300/400 sizes cover smaller ports. Choose the drain to match maintenance routines - manual drain (this unit) needs periodic draining by hand, while automatic and differential-pressure drains handle condensate without operator action. Filtration is 40 um standard; specify code W for the 5 um grade where finer protection is needed. Gauge style (embedded square or external round) and scale (MPa, psi or bar - this unit is round, psi) are decodable choices, as are PT (standard), G and NPT threads and the bracket option (this unit has none). Flow is published as curves, not a single rating, so 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure and downstream demand and we will confirm the flow and datasheet figures for this exact configuration on request.
The M in the code specifies a manual drain: condensate collected in the aluminium alloy bowl is released by operating the drain by hand, which suits installations checked on a routine. The same series is also available with automatic or differential-pressure drains - specify the drain code when ordering.
