The AirTAC GFR600C20LF2 AirTAC Filter Regulator 3/4 in, 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 GFR600C20LF2 is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This 600-size unit is built with 3/4 in PT ports, a 40 um standard filter element, a differential-pressure drain and an aluminium alloy bowl. It is the low-pressure (L) regulator type and comes fitted with an embedded square gauge reading in psi, with a mounting bracket included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options that include a 5 um element (code W), automatic or manual drains, gauge scales in MPa or bar, an external round gauge, and G (BSPP) or NPT threads ordered to specification. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, 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.

Regulating filtered air to low-pressure clamping and holding fixtures on a machining cell, where the operator sets a gentle, repeatable clamp pressure downstream of the drain bowl.
Supplying filtered, pressure-controlled air to air-knife nozzles that strip rinse water from bottles before labelling, with the bowl catching moisture carried in from the ring main.
Feeding clean, regulated pilot air to positioners and pilot solenoids on large process valves in a water-treatment plant, where modest pilot pressures are required.
Choose the size by port and flow demand: 600 is the largest GFR size and this unit carries 3/4 in PT ports, while 200/300/400 sizes step down from 1/8 in to 1/2 in for smaller lines. The drain here is differential-pressure, which clears the bowl automatically as the pressure difference across the element builds; automatic (A) and manual (M) drains can be ordered instead. The 40 um element is the standard grade; specify code W for the 5 um grade where finer particulate removal matters. The fitted square gauge reads psi, with MPa or bar scales and an external round gauge as alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and the mounting bracket is included. Because flow is published as curves rather than a single rated figure, send us your flow and pressure requirements 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 GFR series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and required flow and we will confirm sizing from the datasheet on request.
It marks the low-pressure regulator type. The exact adjustment range for this variant is not published in the material we hold, so we confirm it on request. The unit otherwise filters to 40 um, drains by differential pressure and carries a square gauge reading in psi.
