The AirTAC GFR60020LJC2WT AirTAC Filter Regulator 3/4 in NPT 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 GFR60020LJC2WT is a size-600 filter regulator: it removes water and particulate from compressed air and holds a set downstream pressure in a single body. This configuration is built with 3/4 in NPT ports, the 5 um filter element (code W), a differential-pressure drain that bleeds condensate whenever the pressure drop across the element rises, and a low-pressure regulator type. The size-600 bowl is aluminium alloy, and this unit carries an external round gauge with a psi scale instead of the standard embedded square gauge. No mounting bracket is fitted (code J).
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um filtration, and PT, G or NPT threads. 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 rated figure, so ask us to confirm the datasheet and sizing 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. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| 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 cartoning or case-packing line, this filter regulator cleans the shop air and holds a steady low-pressure setting to the packaging machine's pneumatic actuators, with the 5 um element protecting the machine's valves from water and debris.
Feeding air to textile looms and spinning auxiliaries, the unit filters incoming compressed air and regulates it to the low setpoint the process calls for, while the differential-pressure drain keeps condensate from travelling down the line.
On a CNC cell with pneumatically clamped fixtures, the GFR60020LJC2WT conditions the main 3/4 in supply and holds the regulator at the pressure the clamp circuit was designed around, with the round psi gauge giving a clear local reading.
Start with the port step: this unit is the size-600 body with 3/4 in NPT threads, the largest size in the GFR range, chosen when the line volume calls for the biggest ports. Filtration here is the 5 um element (code W) rather than the 40 um standard - pick 5 um when downstream valves, cylinders or instruments need finer air. Drain is the differential-pressure type, which discharges condensate automatically as the element loads; automatic (float) and manual drains are the other catalogue choices. The gauge on this code is the external round type with a psi scale; embedded square gauges with MPa, psi or bar scales are the alternative. Threads can be ordered as PT (standard), G (BSPP) or NPT, and a mounting bracket is optional on this family. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 flow for the GFR series as curves, not as a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure, set pressure and the equipment you are feeding, and we will confirm the sizing against the datasheet on request before you order.
The differential-pressure drain (the default, with no letter in the code) discharges collected condensate automatically whenever the pressure drop across the 5 um element rises past its threshold. If you prefer a float-operated automatic drain or a simple manual drain, those are the other catalogue options on GFR units - just specify code A or M when ordering.
