The AirTAC GFR600C20ALJC1T 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 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 AirTAC GFR600C20ALJC1T is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is threaded NPT3/4 (3/4 in), carries the standard 40 um filter element, and has an automatic drain that bleeds collected condensate from the bowl without manual attention. The regulator is the low-pressure type, and a round pressure gauge scaled in MPa is fitted so the setpoint can be read directly. The bowl on this size is aluminium alloy, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard, G and NPT as order options), drain types (differential-pressure, automatic or manual), 40 um or 5 um elements, gauge styles and scales, and standard or low-pressure regulation. Flow is published as curves rather than a single rating, so ask us to confirm the figures against 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.

Filtering and regulating the air feeding paint-line tool circuits, where the low-pressure regulator type and automatic drain keep the supply conditioned without daily bowl checks.
Conditioning the 3/4 in branch line that feeds conveyor-mounted pneumatic cylinders and clamps, with the fitted MPa gauge giving operators a visible setpoint.
Supplying filtered, regulated air to pneumatic control valves on a process skid, where the automatic drain handles condensate in an unattended plant room.
Start with the port step: size 600 with a 3/4 in NPT thread suits lines plumbed at that port size, and larger sizes carry higher flow capacity - we confirm the actual curve for your demand on request. Choose the drain to match access: automatic (this unit) suits installations that are not checked daily; manual suits attended setups; differential-pressure drain is the catalogue default. Pick the 40 um standard element for general air prep, or the 5 um W option where finer filtration is needed. Gauge style (embedded square standard, external round optional) and scale (MPa, psi or bar) are decodable choices, as is the thread: PT is the standard, with G (BSPP) and NPT ordered as options, and a bracket can be added or omitted.
Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing from 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 this series as curves, not as a single rated figure, so we do not quote a number here. Send us your line size and air demand and we will confirm the flow from the datasheet to check the unit is sized correctly before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without anyone opening it - useful for units mounted out of easy reach. The GFR family is also available with a manual drain or the differential-pressure drain as the catalogue default, and the 40 um element on this unit can be swapped for the finer 5 um (code W) option when ordering.
