The AirTAC GFR60020LF3TK AirTAC Filter Regulator NPT3/4 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 AirTAC GFR60020LF3TK is a GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built for 3/4 in NPT ports, is the low-pressure regulator type, uses the differential-pressure drain, carries the standard 40 um filter element, and has an embedded square gauge scaled in bar. A reverse/check valve is fitted and the mounting bracket is included. The size 600 bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and is offered with manual or automatic drains, a 5 um (W) filter grade, alternative gauge scales, and G or NPT threads in place of the PT standard. 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 sizing and 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.

| (blank) | Drain: Differential-pressure drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 clamping and hold-down cylinders on carton-sealing and case-packing lines that run on a reduced-pressure air circuit, delivering filtered, regulated air at each station with the built-in check valve in the air path.
Supplies clean, pressure-controlled air to leak and functional test rigs where the low-pressure regulator type matches the reduced operating pressure of the test circuit and the 40 um element protects the fixtures.
Provides filtered, regulated air to air-jet nozzles that clear bottles and labels along the line, with the 40 um element stopping particulate from reaching the nozzles and the square bar gauge giving operators a setpoint reference.
Choose by size and port first: the 200/300/400/600 steps move up in port size and flow capacity, and this unit already sits at the top with 3/4 in NPT threads. Where a bowl is fitted you can order the differential-pressure drain (as here), an automatic drain (A) or a manual drain (M), and the filter grade is 40 um standard or 5 um with W. Gauges are embedded square as standard with MPa, psi or bar scales and an external round gauge is optional; threads can be ordered as PT (the standard), G (BSPP) or NPT; a bracket is included and the K code adds the reverse/check valve. Because flow is published as curves rather than a single rated figure, send us your flow and pressure requirements and we will confirm the right size before you order.
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 G-series flow as performance curves rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm sizing and the datasheet figures for GFR60020LF3TK on request.
L marks the low-pressure regulator type. This variant is intended for circuits that run below standard line pressure; the exact adjustment range for the low-pressure type is not published in the catalogue, so we confirm it on request before you order.
