The AirTAC GFR600C20MLF2K AirTAC Filter Regulator PT3/4, 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 GFR600C20MLF2K is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This 600-size unit carries a 3/4 in PT port, a manual-drain bowl in aluminium alloy, and the standard 40 um filter element. The L code selects the low-pressure regulator type, the fitted square gauge reads in psi, and the K code adds a reverse (check) valve so downstream pressure cannot back-feed through the unit. A mounting bracket is included, 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 from the GFR range, which spans 200 to 600 sizes with ports from 1/8 to 1 in, PT as standard and G or NPT threads to order, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, gauge scales in MPa, psi or bar, and standard or low-pressure regulator types. Flow for this series is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Filtered, regulated air for the capper and labeler pneumatic actuators on a beverage bottling line, where the low-pressure regulator type holds a gentle working pressure and the manual drain is emptied during scheduled line washdowns.
Conditioning the supply to a bank of directional control valves on a packaging machine: the 40 um element protects valve spools from water and swarf, the check valve holds downstream pressure when upstream supply is lost, and the psi gauge gives operators a local setpoint readout.
Air preparation for pop-up diverters, stoppers and pushers on a distribution conveyor, where the 3/4 in PT port feeds higher-consumption cylinder circuits and the manual drain suits a staffed maintenance round.
Size and port are the first choice: this 600 body carries a 3/4 in PT port, the largest step in the range, with G (BSPP) or NPT threads available as order options. Drain type matters in practice: this unit uses a manual drain, which suits installations where an operator can bleed the bowl on a routine; automatic or differential-pressure drains are the alternatives for unattended lines. The 40 um element is the standard grade; specify code W for 5 um where finer particulate removal is needed. The fitted square gauge reads in psi, and MPa or bar scales can be ordered instead. Because flow is published only as curves, not as a single rated figure, send us your application details and we will confirm sizing against the datasheet 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 GFR600 series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, required downstream pressure and air consumption, and we will confirm the flow from the datasheet on request before you order.
The L code selects the low-pressure regulator type of the GFR unit. The exact adjustment range for this variant is not published in our validated data, so tell us your target set pressure and we will confirm suitability from the datasheet before you order. The manual drain, 40 um element, square psi gauge and fitted check valve are unaffected by this choice.
