The AirTAC GFR600C20MLF1WT AirTAC Filter Regulator NPT 3/4 in 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 GFR600C20MLF1WT is a filter regulator: water and particulate removal plus pressure regulation combined in a single body. This size-600 unit is built for 3/4 in NPT ports and carries the 5 um filter element (the W grade; 40 um is the standard alternative), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type. A square pressure gauge with an MPa scale is fitted, a mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
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, PT as the standard thread and G or NPT as order options, plus a choice of drain type, filter grade and gauge scale. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet numbers against 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.

Feeding clamps and actuators that run below standard shop-air pressure, with 5 um filtration protecting the valves and the square gauge giving a direct MPa set-point reading.
Preparing air for a carton-sealing or wrapping line: the filter stage strips water and fine particles ahead of the regulator, and the manual drain suits a shift-based maintenance routine.
Conditioning the 3/4 in supply line to a spray booth, where the 5 um element handles finer filtration ahead of pressure control for the guns.
Choose the size and port step against the air demand of your line: this unit is size 600 with 3/4 in NPT threads (PT is the catalogue standard; G and NPT are ordered as options). The 5 um element suits points of use that need finer filtration than the standard 40 um grade, and the manual drain means the bowl is bled by hand on a routine you set - automatic and differential-pressure drains are available elsewhere in the family. The square gauge reads in MPa, an external round gauge in MPa, psi or bar can be ordered, and a mounting bracket is included with this code. Flow is published as curves, not a single rating, so send us your flow and pressure requirements 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 GFR600 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain: the bowl is bled by hand on a routine you set, instead of automatically. The W code selects the 5 um element rather than the standard 40 um grade, for finer particulate removal ahead of the regulator.
