The AirTAC GFR600C20LJC1TK 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 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 GFR600C20LJC1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in a single body. This size 600 unit has a 3/4 in NPT port, the 40 um standard filter element and a differential-pressure drain (the standard drain type; automatic and manual drains are order options). It is the low-pressure (L) regulator type, a reverse/check valve is fitted, and no mounting bracket is supplied. The round external pressure gauge with an MPa scale is fitted; the embedded square gauge is the standard alternative. As a size 600 unit its bowl is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -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 including the finer 5 um (W) element, manual or automatic drains, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT threads in place of the PT standard, and brackets. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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. 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.

Feeds a low-pressure adhesive or coating circuit on a converting or packaging line: the filter stage strips water and pipe scale before the regulator holds a gentle, stable supply pressure to the applicator heads, with the check valve holding the setting against backflow.
Sits on a branch of a plant air distribution panel where one circuit needs a filtered, reduced supply for sensitive actuators or instruments, while the main panel runs at full line pressure. The 3/4 in NPT port suits a main branch take-off.
Supplies a filtered, low-set air circuit for purge and gentle blow-off points on a bottling or canning line, keeping condensate and particles out of nozzles that touch product-contact areas. The differential-pressure drain handles collected water without daily manual draining.
The real choices when specifying: step through sizes 200, 300, 400 and 600 - each size pairs with specific ports (here 3/4 in NPT) and a larger flow capacity, so match the size to the air demand of the circuit. Choose the drain type: differential-pressure (this unit), automatic (A) or manual (M). Choose the element: 40 um standard or 5 um (W) for finer filtration. Gauges: this unit carries the round external gauge with an MPa scale; the embedded square gauge and psi or bar scales are options. Threads: PT is the AirTAC standard, while G (BSPP) and NPT (this unit) are catalogue options. Brackets are optional - this configuration is supplied without one.
The L code marks the low-pressure regulator type; its exact adjustment range is not published in the catalogue, so confirm it against your set pressure with us before ordering. The same applies to sizing: flow is published as curves, not a single rating, so send us your demand and we will confirm the right size from the datasheet.
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 number here. Send us your line pressure, set pressure and air demand, and we will confirm from the datasheet whether the size 600, 3/4 in GFR600C20LJC1TK suits your application before you order.
The L code marks the low-pressure regulator type, and the catalogue does not publish an exact adjustment range for it, so we will not guess one. Tell us the set pressure your circuit needs and we will confirm suitability on request. Everything else on this unit is as coded: differential-pressure drain, 40 um element, round MPa gauge, fitted check valve, no bracket.
