The AirTAC GFR600-20 AirTAC Filter Regulator PT3/4, 5 um, Manual Drain 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-20 is a filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single body. This 600-size unit is threaded PT3/4 (3/4 in) and carries a 5 um filter element (the finer of the two catalogue grades), a manual drain on the bowl, and a round pressure gauge reading in psi. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.05 - 0.9 MPa (7 - 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.

Point-of-use conditioning for a CNC machining centre: the 5 um element protects solenoid valves and tool-clamp cylinders from water and swarf-laden air, while the regulator holds a steady setting for clamping and tool-change circuits on a 3/4 in drop.
Conditioned air for diverters, stoppers and vacuum grippers along a packaging conveyor. The manual drain suits a line that is bled down at shift start and end, and the psi gauge lets technicians set and verify actuator pressure at the machine.
Filtering and regulating air to filler and capper actuator headers in a bottling hall. The 3/4 in PT port serves the larger header lines, the 5 um grade keeps moisture and particles out of food-area pneumatic components, and the aluminium bowl suits the 600-size flow path.
Step up or down through the GFR sizes (200/300/400/600) to match the port size and flow demand of your air line - this is the 600 size with a 3/4 in PT port, the largest in the family. Choose the drain to suit access: manual (as here) means someone bleeds the bowl on a routine, automatic drains continuously, and the differential-pressure default drains on a set pressure drop. Filtration is 40 um standard or 5 um (W) where finer protection is needed - this unit carries the 5 um element. Gauges can be the embedded square type or an external round gauge, in MPa, psi or bar scale; this one is round, psi. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket can be added if the code calls for one.
Because AirTAC publishes flow only as curves and not as a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm the datasheet and check the sizing against your required flow 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 number, so we do not quote a flow figure on the product page. Tell us your line pressure, downstream demand and allowable pressure drop, and we will confirm the datasheet and check the GFR600-20 against your required flow before you order.
The M in the code GFR60020MJC2W specifies a manual drain: condensate collected in the aluminium bowl is released by operating the drain by hand, which suits installations that are checked on a routine. If the unit sits where regular attention is unlikely, an automatic drain (code A) drains continuously without operator input, and the differential-pressure default drains on a set pressure drop. All three are catalogue options across the GFR family.
