The AirTAC GFR600C20LJC2K AirTAC 3/4 in Filter Regulator 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 GFR600C20LJC2K is a filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your setpoint. This size 600 unit has a 3/4 in PT port, the standard 40 um filter element and a differential-pressure drain that clears collected condensate automatically whenever the pressure differential is high enough. The 600-size bowl is aluminium alloy, a round gauge scaled in psi is fitted, a reverse/check valve is built in, and no mounting bracket is included. This is the low-pressure (L) type, intended for applications regulated below the standard band; its exact adjustment range is not published, so confirm your setpoint with us.
This is a genuine AirTAC part. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include manual or automatic drains, a 5 um element (code W), gauge scales in MPa, psi or bar, G or NPT threads and a mounting bracket. Flow is published as curves rather than a single rating, so send us your application and we will confirm the figures from the datasheet 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.

Feeds clean, regulated air to pilot-operated process valves along the filler. The 40 um element keeps scale and pipe debris out of the valve pilots, the built-in check valve holds the downstream setting through supply dips, and the psi gauge lets technicians verify the setpoint at the station.
Prepares the air feeding workholding clamps and swing cylinders on a machining cell. Water and chips-laden condensate are stripped out before the directional valves, the low-pressure type suits gentler clamp setpoints, and the 3/4 in PT port serves as a cell-level supply point.
Regulates the air driving stoppers, pushers and diverters on a carton conveyor. The differential-pressure drain clears condensate automatically between cycles, the aluminium 600-size bowl stands up to continuous line duty, and the psi gauge makes setpoint checks quick during changeovers.
Size and port step up with flow demand: this is the largest GFR size, 600, with a 3/4 in PT port; G and NPT threads are ordering options only, since PT is the standard. The 40 um element suits general plant air; specify the W code for the 5 um element where downstream equipment needs finer filtration. The differential-pressure drain is the default and needs no setting; automatic (A) and manual (M) drains are available in the family. The fitted gauge is scaled in psi, with MPa and bar scales as options. Flow is published as curves, not a single rated figure, so 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. 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 rather than a single rated figure, so we do not quote one number. Tell us your line pressure, set pressure and air demand, and we will confirm the sizing from the datasheet on request before you order.
This unit is the L version of the GFR600, intended for applications regulated below the standard band. The exact adjustment range for the low-pressure type is not published, so confirm your setpoint with us before ordering. The round gauge fitted on this model is scaled in psi, and MPa or bar scales are available as options.
