The AirTAC GFR600C20LJC2 AirTAC Filter Regulator PT3/4 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 See datasheet 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 GFR600C20LJC2 is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit has PT3/4 ports, the standard 40 um filtration element, and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure differential across the element is high enough. It is the low-pressure regulation type, suited to circuits that hold a lower set pressure than a standard regulator is intended for, and it leaves the factory with an external round gauge scaled in psi. The metal bowl on this 600 size is aluminium alloy, and the code confirms no mounting bracket and no reverse/check valve are fitted.
This is a genuine AirTAC part from the GFR family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, and options including automatic or manual drains, a 5 um element (code W), different gauge scales, G or NPT threads, and a mounting bracket. Flow is published as curves rather than a single rated figure, so send us your application details and we will confirm the sizing and datasheet figures 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

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 stamping-shop pneumatic clamp line, this 3/4 in filter regulator cleans the plant air of water and scale and holds a steady low set pressure to the clamp cylinders, with the psi gauge letting the shift technician verify the setting at a glance.
A bottling plant's filling-head and capper actuators need air that is free of condensate droplets and held at a gentle, stable pressure; this unit's 40 um element, differential-pressure drain and low-pressure regulation type serve that job on a 3/4 in supply drop.
On a carton-packing conveyor with pneumatic diverters and pushers, this filter regulator conditions the branch supply and regulates it at a low set point, protecting the valve manifold and cylinders from water carryover and pressure drift.
Start with the port step: this unit is size 600 with PT3/4 ports, the largest in the GFR range, so step down to 300/400 if your line runs smaller ports and lower air demand. Drain choice is a real decision: the differential-pressure drain fitted here needs no operator attention, while an automatic drain (code A) empties on a cycle and a manual drain (code M) is emptied by hand. The standard element is 40 um; specify code W if the circuit needs 5 um filtration. The round gauge fitted here is scaled in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket can be added (this unit is coded J, no bracket).
One honest note before you order: AirTAC publishes flow for this family as curves, not as a single rated number, so ask us to confirm the flow against your application before you commit to a size.
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 family as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and the air demand of the equipment, and we will confirm the flow from the datasheet on request before you order.
The blank drain code on this model means the differential-pressure drain is fitted: condensate collected in the aluminium bowl is bled off automatically whenever the pressure drop across the 40 um element is high enough, so no one has to drain it by hand. If your application suits a timed automatic drain (code A) or a manual drain (code M), those are catalogue options on the same family - just ask and we will decode the right variant for you.
