The AirTAC GFR600C20MLJF2WTK AirTAC Filter Regulator NPT3/4 5um 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body. This unit is built on the 600 size with a 3/4 in NPT port, a 5 um filter element (code W), a manual drain, and the low-pressure regulator type. The 600 frame uses an aluminium alloy bowl, an embedded square gauge reading in psi is fitted, and a reverse/check valve is included. No mounting bracket is supplied with this code.
This is a genuine AirTAC part. The G-series filter regulator line spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um filtration, and gauge and thread options. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the figures for your application.

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 main air drop feeding a stamping or forming press circuit, where the 3/4 in NPT port serves the plant's primary downstream manifold and the low-pressure regulator type matches circuits set to reduced pressures.
Supplying clean, regulated air to cylinder-driven case erectors and sealing heads on a carton packaging line, with the 5 um element protecting directional valves and cylinders from particulate carryover.
Feeding filtered, regulated air to weld-tip cleaning stations and tool-changer circuits in a robotic welding cell, with the manual-drain bowl suited to cells checked on a routine maintenance round.
Size and port set the air capacity: within the GFR range, the step from 200 up to 600 raises both the port size (here 3/4 in NPT) and the flow capacity, so match the size to the demand of the circuit rather than to the pipe alone. Drain type is a real choice - manual (this code), automatic, or differential-pressure - and filter grade is 40 um standard or 5 um (W) for finer protection of downstream components. Gauge style and scale (embedded square or optional external round; MPa, psi or bar), thread (PT standard, with G or NPT as order options) and the bracket are likewise decodable choices. Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm sizing against 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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and the full datasheet figures for this exact model on request.
The L code makes this the low-pressure regulator version, intended for circuits set to reduced pressures; its exact adjustment range is not published, so ask us to confirm it. The M code means a manual drain: the bowl is drained by hand rather than automatically, which suits installations serviced on a fixed maintenance schedule.
