The AirTAC GFR600C20MF1WT AirTAC Filter Regulator NPT3/4 5 um 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 GFR600C20MF1WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is threaded NPT 3/4 in, carries a 5 um filter element (the fine grade; 40 um is the standard option), and drains by hand via the manual drain on the bowl - you open it during maintenance rather than relying on an automatic mechanism. The standard regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and the embedded square gauge reads in MPa so you can set and monitor outlet pressure directly. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 600 the bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of manual, automatic or differential-pressure drains, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, 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 0.15 - 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.

Point-of-use preparation for the air feeding tool clamps and actuated fixtures on a CNC machining centre: the 5 um element protects fine components from particulate while the regulator holds a steady setting for repeatable clamping.
Conditioning the branch line that feeds pick-and-place and carton-forming cylinders on a packaging conveyor line, where water carry-over from the compressor would otherwise reach the valves and the pressure needs to be set below header level.
Filtered and regulated air for pneumatic actuated ball and butterfly valves on a process skid, with the square MPa gauge giving operators a local reading of the actuator supply pressure at the set point.
Choose the size and port step against the air consumption of the circuit downstream - larger sizes carry larger ports and more flow, and this unit is already at the top of the range with a 3/4 in NPT thread. On filtration, 40 um suits general plant air protection, while the 5 um element fitted here is the choice where finer particulate removal matters; note that finer filtration loads faster and needs more frequent draining. The manual drain means an operator opens the bowl drain during checks - if nobody is available to do that routinely, consider an automatic or differential-pressure drain variant instead. Gauge scale can be ordered in MPa, psi or bar, thread can be PT (standard), G or NPT, and a bracket is included for panel or wall mounting. Flow for this series 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow figures from the datasheet so you can size the unit correctly before ordering.
The M in the code specifies a manual drain: condensate collected in the aluminium alloy bowl is emptied by hand during maintenance. If the unit will be installed where nobody drains it routinely, an automatic (A) or differential-pressure (blank) drain variant is the better choice - both are available in the same GFR600 size.
