The AirTAC GFR60020LF1TK AirTAC Filter Regulator NPT3/4 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 GFR60020LF1TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is the low-pressure type with a 3/4 in NPT port, a 40 um standard filter element, a differential-pressure drain on the bowl, an embedded square gauge scaled in MPa, a reverse/check valve fitted, and a mounting bracket included. The aluminium alloy bowl suits the largest frame in the GFR range.
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600, with port options, drain types, 5 um (W) filtration, gauge styles and scales, and thread options as orderable choices. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet for your application before ordering.

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.

|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 filtered, regulated air to clamping fixtures and vises on a machining line, holding a steady low-pressure setpoint so workpieces stay gripped without over-clamping.
Conditions the air supply to sealing jaws and forming heads on a packaging line, where the low-pressure type regulator keeps delicate actuation circuits stable and the 40 um element blocks scale and pipe debris.
Supplies clean, regulated air to diverter gates and stopper cylinders along a conveyor system, with the check valve holding downstream pressure if the supply dips.
Start with the port step: size 600 carries a 3/4 in port, and moving up or down a size changes both the port and the flow capacity, so match the frame to the air demand of the circuit. Choose the drain: differential-pressure (this model), automatic (A) or manual (M). Filter grade is 40 um standard or 5 um with code W. Gauge style is embedded square (standard) or external round, with MPa, psi or bar scales, and the thread can be ordered as PT, G or NPT. This unit is the low-pressure type, so confirm its regulation range against your setpoint - we can supply the exact figure on request. Flow is published as curves, not a single rating, so ask us to confirm sizing against the application before ordering.
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 this series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow data from the datasheet on request before you order.
The L in the code marks the low-pressure regulator variant, intended for circuits set below the standard type's range. Its exact adjustment range is not published in our sheet, so ask us to confirm it against your setpoint. The rest of the decode is standard: 3/4 in NPT port, 40 um element, differential-pressure drain, square MPa gauge and a fitted check valve.
