The AirTAC GFR600C20MLF2GK AirTAC Filter Regulator G3/4, Low-Pressure 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 GFR600C20MLF2GK is a size 600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a G3/4 (BSPP) female port. This configuration is the low-pressure regulator type with a manual drain bowl, a 40 um standard filter element, an embedded square gauge scaled in psi, a reverse/check valve fitted, and a mounting bracket included. The size 600 bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Medium is compressed air only.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge scale, thread form and regulator type. Because flow is published as curves rather than a single rated figure, we confirm the datasheet and sizing 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.

Feeds a workholding clamp manifold on a machining cell press, filtering condensed water and swarf-laden particles from the shop air while holding a reduced, stable set pressure so clamping force stays consistent part to part. The manual drain lets maintenance bleed accumulated condensate at shift start.
Supplies the air cylinders that drive box diverters, flap tuckers and sealing jaws on a carton packaging line. The 40 um element protects the directional valves from particulate, the psi-scaled square gauge gives operators a readable setpoint, and the check valve holds the circuit if supply is interrupted.
Conditions the supply to thread-guiding air jets and tension rollers on a weaving or spinning frame, where the low-pressure regulator type matches the gentle set pressures these devices run at. The aluminium size 600 bowl and manual drain suit a fixed installation tended by the mill's maintenance round.
Step up through the GFR sizes (200/300/400/600) and their port options until the port and the flow curve match your line's demand - this unit is the 3/4 in G-thread step at size 600. Choose the drain to suit access: manual drain (this unit) needs an operator to bleed the bowl, while automatic and differential-pressure drains self-bleed. Filter grade is 40 um standard; specify the W code for the 5 um element if downstream valves need finer filtration. The embedded square gauge is standard and can be scaled in MPa, psi (this unit) or bar; an external round gauge is optional. PT is the standard thread, with G and NPT available as order options - this unit carries G. A bracket is included; the J code omits it. The low-pressure regulator type suits circuits with reduced set pressures; its exact regulation range is not published, so ask us to confirm it against your setpoint before ordering. Flow is published as curves, not a single rating, so send us your application and we will confirm sizing before you order.
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, not as a single rated number, so we do not quote a figure here. Tell us your line's air demand and upstream pressure and we will confirm the correct size and the datasheet flow curve for the GFR600 at your conditions before you order.
The M in the code selects a manual drain: condensate collected in the aluminium bowl is released by an operator rather than self-bleeding, which suits attended installations. The L code selects the low-pressure regulator type, intended for circuits with reduced set pressures; its exact regulation range is not published, so we confirm it on request. The unit also carries a 40 um element, a square psi gauge, a reverse/check valve and a bracket.
