The AirTAC GFR600C20LF1TK AirTAC Filter Regulator NPT3/4, 40 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 GFR600C20LF1TK is an AirTAC GFR filter regulator: a 600-size unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded NPT3/4 (3/4 in), carries the standard 40 um filter element, and uses the differential-pressure drain, which discharges collected condensate based on the pressure differential rather than a manual routine. Because it is a 600-size unit, the bowl is aluminium alloy. The regulator is the low-pressure type, an embedded square gauge scaled in MPa is fitted, a reverse (check) valve is built in, and a mounting bracket is included. 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. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include a 5 um filter element (code W), automatic or manual drains, G (BSPP) or NPT threads in place of the PT standard, alternative gauge scales (psi or bar), and an external round gauge. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm sizing and full datasheet figures 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.

Feeding 3/4-in supply air to clamp and press cylinders on a stamping cell, where filtered, regulated air protects seals and supports consistent clamp force.
Supplying pop-up diverters and gates on a parcel-sortation conveyor, with the built-in check valve holding downstream pressure if the supply dips.
Regulating air to bagger and sealer actuators on a packaging line, with the 40 um element keeping pipe scale and condensate out of the directional valves.
Size and port are the first decision: the 600 size with its 3/4 in NPT port suits lines with higher air demand, while the 200/300/400 sizes cover 1/8 to 1/2 in ports. Drain choice matters: the differential-pressure drain fitted here suits lines with enough pressure variation to clear the bowl, while automatic (A) and manual (M) drains are order options. Filter grade is the 40 um standard here; choose the W code for 5 um where finer particulate protection is needed. The fitted square gauge reads in MPa, with psi and bar scales and an external round gauge available to order. Threads can be ordered in G (BSPP) or NPT instead of the PT standard, and a no-bracket (J) variant exists. One honest note: AirTAC publishes flow as curves, not a single rating, and the exact adjustment range of this low-pressure regulator is not in the standard table - ask us to confirm both against your setpoint and demand 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, setpoint and expected air demand, and we will confirm sizing and the full datasheet figures for this 3/4-in unit on request.
This unit uses the differential-pressure drain, the catalogue default, which discharges condensate when the pressure differential is sufficient. AirTAC also offers automatic (code A) and manual (code M) drains; if your line runs at low or steady pressures, ask us which drain suits before ordering.
