The AirTAC GFR600C20MLJF1WT AirTAC 3/4 in NPT Filter Regulator 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 GFR600C20MLJF1WT is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built around a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), and a manual drain you operate by hand to empty the bowl. The regulator is the low-pressure type, and an embedded square gauge scaled in MPa is fitted so the set pressure is visible at the unit. Because this is the size-600 model, the bowl is aluminium alloy rather than polycarbonate. No mounting bracket is included with this code.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options for drain type, filter grade, gauge style and scale, thread form (PT standard, G and NPT to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Conditioning and pressure control at the drop to a paint spray booth, where the 5 um element helps keep water and particulate out of the air feeding spray equipment and the manual drain is emptied during shift checks.
Filtering and regulating the supply to pneumatic cylinders and stopper gates on a packaging conveyor, with the 3/4 in port matching the main air drop feeding the conveyor section.
Clean, regulated air ahead of a directional-valve manifold on a machine's pneumatic panel, with the fitted MPa gauge giving operators a visible setpoint at the unit.
Start with the port step: this unit is 3/4 in NPT on the size-600 body, the largest GFR frame, so size up to it when your line flow and piping demand a 3/4 in connection. Choose the drain to suit access: this code has a manual drain, which suits attended installations; automatic and differential-pressure drains are available on other codes for unattended duty. The 5 um element (code W) is the finer filtration choice where downstream equipment needs cleaner air than the 40 um standard. The fitted square gauge reads in MPa; psi and bar scales and an external round gauge are alternatives. Thread is NPT here, ordered as an option against the PT standard, and this code omits the mounting bracket. Flow is published as curves, not a single rating, so 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 GFR flow as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the datasheet curves and check the sizing against your required flow before you order.
The M in the code means the bowl drain is operated by hand, which suits installations that are checked regularly. Automatic and differential-pressure drain options are available on other GFR codes for duty where the bowl cannot be drained manually; note that the regulation range also differs by drain type, and for this low-pressure type code the exact range is not published, so confirm it with us.
