The AirTAC GFR600C20MLC3T AirTAC Filter Regulator NPT3/4 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 GFR600C20MLC3T is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, a manual drain on the aluminium alloy bowl, the standard 40 um filter element, and the low-pressure regulator type. A round external gauge with a bar scale is fitted, no reverse/check valve is included, and the mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet 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 shop-air feed to low-pressure clamping cylinders on a CNC machining centre, keeping water and chips out of the clamp circuit while holding a low set pressure.
Supplying clean, regulated air to diverter and gating cylinders on a packaging conveyor, where the manual-drain bowl is emptied during scheduled line clean-downs.
Conditioning the compressed-air drop to a laboratory bench manifold that feeds pneumatic sample-handling actuators, with the bar-scale gauge giving a local pressure readout.
Choose the size and port step against the air demand of the circuit: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range. Drain choice matters: this version is manual drain, so the aluminium alloy bowl is emptied by hand; automatic and differential-pressure drain versions are available in the series. The filter element is the standard 40 um grade, with a 5 um option (code W) where finer filtration is needed. The fitted round gauge reads in bar; the embedded square gauge and MPa or psi scales are the alternatives. Thread here is NPT, one of the order options alongside G (BSPP), with PT as the standard thread. This is the low-pressure regulator type; we confirm its adjustment range on request. Because flow is published as curves rather than a single rating, ask us to check sizing against your application before ordering.
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 working pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code specifies a manual drain: condensed water collected in the aluminium alloy bowl is drained by hand as part of routine maintenance. If you prefer unattended draining, the GFR series is also available with automatic or differential-pressure drains - ask us for those variants.
