The AirTAC GFR60020LJC2WTK AirTAC Filter Regulator NPT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR600 series combines filtration and pressure regulation in a single body: compressed air passes a 5 um filter element that removes water and particulate, then flows through the low-pressure regulator. This unit is the 600 size with 3/4 in NPT threads, fitted with a differential-pressure drain, an external round gauge in psi and a reverse/check valve, and it is supplied without a mounting bracket. The aluminium alloy bowl suits the larger 600 frame, and the unit operates at up to 1.0 MPa (145 psi) inlet over a temperature range 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 to 1 in, and options that include manual or automatic drains, the 40 um standard element, embedded square or external round gauges in MPa, psi or bar scales, and G, NPT or PT threads. Air flow for this series is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |

| W | Filtering grade 5 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.

On a weaving line, air jets run at reduced pressure and clog quickly with dirty air. This filter regulator cleans the supply through the 5 um element, holds the low jet pressure with the regulator and psi gauge, and the reverse/check valve helps hold the setting if the main supply dips.
A 3/4 in main feed serving box-closing and flap-tuck cylinders needs clean, regulated air at a modest working pressure. This unit filters water and particulate before the valves, regulates the low-pressure circuit, and the differential-pressure drain carries off condensate as air flows.
Before filling, bottles are dried with low-pressure air nozzles. This unit strips water and fine particles from the 3/4 in supply, sets the gentle nozzle pressure on the psi gauge, and the aluminium bowl stands up to the larger 600 frame duty.
Choose the 600 size when your line runs 3/4 in piping and higher air demand; the smaller 200-400 frames cover 1/8 to 1/2 in ports. This configuration is the low-pressure type, so confirm its setting range against your application before ordering. The 5 um element (code W) gives finer protection than the 40 um standard; the differential-pressure drain bleeds condensate automatically with air flow, while automatic and manual drains are orderable alternatives. The gauge scale here is psi, with MPa and bar scales, G or PT threads, and a mounting bracket available as options. Because flow is published as curves, 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR600 as curves rather than a single rated figure, so we do not quote a number here. Send us your operating pressure and air demand and we will confirm the datasheet curve and sizing for your application before you order.
This GFR600 is built as the low-pressure regulator version rather than the standard type. Its exact setting range is not published in the catalogue, so confirm your required downstream pressure with us before ordering; the standard GFR regulation range does not apply to this unit.
