The AirTAC GFR600C20MLF1TK 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 GFR600C20MLF1TK is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, a manual drain on the bowl, and a low-pressure type regulator with an embedded square MPa gauge. A reverse/check valve is fitted, a mounting bracket is included, and at size 600 the bowl is aluminium alloy. Maximum working (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 is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard; G and NPT as order options), drain types, filter grades and gauge scales, so a variant can be matched to most compressed-air preparation points. Flow is published as curves rather than a single rated figure; ask us and we will confirm the datasheet figures for your application before you order.

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.

At the 3/4 in take-off feeding a packaging hall's header, this unit strips water and chips out of the plant air and holds a low set pressure to the case-sealers and carton tapers, with the manual drain cleared during shift checks.
On the air supply to a pneumatic press or clamping cell, the 40 um element protects valves and cylinders from particulate while the low-pressure regulator holds the gentle setting the tooling needs; the MPa gauge gives the operator a direct read.
Feeding the air jets and diverters on a conveyor line, this filter regulator keeps condensate out of the blow-off circuit and regulates the supply to the divert actuators, with the check valve holding the circuit if supply pressure dips.
Size and port are the first choice: the 200/300/400/600 step sets the port size and the flow capacity, so step up to size 600 (3/4 in here) when the line demand is high. Drain type is a real decision: manual drain (this code) means an operator drains the bowl by hand, while automatic and differential-pressure drain variants handle condensate without that step. Filter grade is 40 um standard; specify the W code for the 5 um element where downstream equipment needs finer filtration. Gauge scale (MPa, psi or bar) and gauge style can be selected, and the thread is PT as standard with G (BSPP) and NPT (this code) as order options; a bracket is included on this variant. Because the regulator in this code is the low-pressure type, tell us your set pressure and we will confirm the adjustment range from the datasheet before ordering; flow is published as curves, not a single rating, so ask us to check sizing against your application.
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 one number here. Tell us your line pressure and demand and we will confirm the flow figure for this exact model from the datasheet before you order.
The M in the code selects a manual drain: an operator opens the bowl drain to expel collected condensate, which suits attended installations; automatic and differential-pressure drain variants are available on other codes in the family. This code is also the low-pressure regulator type, and its exact adjustment range is not published in the standard table, so send us your set pressure and we will confirm the range from the datasheet.
