The AirTAC GFR60020LF2K 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 PT3/4" 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 GFR60020LF2K is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure as a low-pressure type. This size 600 unit is threaded PT3/4 (3/4 in, PT thread standard; G and NPT are order options), carries a differential-pressure drain that bleeds accumulated condensate automatically as flow passes through, an embedded square gauge scaled in psi, and a fitted reverse/check valve that holds downstream settings when upstream pressure is lost.
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, a choice of drain type, 40 um or 5 um filtration, gauge scale options and thread options. 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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 a multi-station assembly cell, this filter regulator cleans the supply of water and swarf and holds a low regulated pressure to the cell's air tools and clamps, with the psi gauge giving the operator a direct reading at the drop.
On a cartoning or case-packing line, the 40 um element protects cylinders and air-actuated sealer heads from condensate and particulate, while the low-pressure regulator type sets the gentler pressure those actuators need and the check valve holds the setting through upstream dips.
Mounted on its bracket at a pneumatic control panel or manifold feed, this unit filters and regulates the branch in one body, the differential-pressure drain keeping condensate moving out during normal flow so the panel's valves stay dry.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start here when your line's flow demand sits above what a 300 or 400 unit serves; match the port step to the pipe and required flow. The differential-pressure drain suits continuous-flow installations where condensate is carried away with the air stream; choose an automatic or manual drain variant if your duty cycle differs. The standard 40 um element is the default for general plant air; specify the W option for 5 um where downstream equipment needs finer filtration. This unit is the low-pressure regulator type - its exact adjustment range is not published in the material we hold, so confirm it with us before ordering. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are alternatives. PT is the standard thread, with G (BSPP) and NPT available to order, and the mounting bracket is included.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow 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 figure, so we do not quote a number here. Tell us your line conditions - inlet pressure, regulated pressure and expected air demand - and we will confirm the sizing against the datasheet curves before you order.
The L in the code marks this as the low-pressure regulator type rather than the standard type; its exact adjustment range is not published in our material, so confirm it with us for your application. The trailing K means a reverse/check valve is fitted, which holds the downstream setting if upstream pressure is lost. The F2 marks the fitted square gauge with a psi scale.
