The AirTAC GFR60020LJF3T 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 GFR60020LJF3T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration carries 3/4 in NPT ports, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically as flow passes through, an embedded square gauge scaled in bar, and the low-pressure (L) regulator type for circuits set below the standard range. The size-600 bowl is aluminium alloy, and the unit is rated to 1.0 MPa (145 psi) maximum inlet pressure with an operating temperature of -5 to 70 C (non-freezing).
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 differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, standard or low-pressure regulation, square or external round gauges with MPa, psi or bar scales, and G or NPT thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| 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.

Conditioning and regulating the shop-air feed to a cartoning or case-sealing machine's cylinders and grippers, with the square bar gauge giving operators a clear setpoint readout at the machine.
Feeding pneumatic clamps, air tables and workholding fixtures that run at reduced set pressures, where the low-pressure regulator type gives finer control below the standard range.
Filtering and regulating the compressed-air supply to bench-top test rigs and pilot-air manifolds, with the differential-pressure drain keeping condensate off the instruments without manual blowdown.
Step up or down through the GFR sizes (200/300/400/600) and their matching ports (1/8 in to 1 in) to suit the flow your line needs - the 600 size with 3/4 in ports sits at the high-flow end. Choose the drain: differential-pressure (this unit, self-bleeding in service), automatic, or manual where you want controlled blowdown. Pick 40 um for general air preparation or the W-code 5 um element where finer filtration matters; note the low-pressure (L) regulator type for circuits set below the standard range. Gauges are embedded square as standard (this unit, bar scale) with an external round gauge optional, and PT is the standard thread with G and NPT as order options - this unit is NPT. Brackets are optional (this unit ships without one). Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
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 GFR flow as curves rather than a single rated figure, so we do not quote a lumped number. Send us your line pressure, set pressure and expected air demand and we will confirm the sizing from the datasheet curves on request before you order.
The L in the code marks the low-pressure regulator type, intended for circuits set below the standard range; the exact regulation range for the low-pressure type is not published, so we confirm it on request. F3 marks the embedded square gauge scaled in bar, with MPa or psi scales and an external round gauge available as options.
