The AirTAC GFR600C20MF3TK AirTAC Filter Regulator NPT3/4, Bar Gauge 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 GFR600C20MF3TK 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 40 um standard filter element, a manual drain on the aluminium alloy bowl, an embedded square gauge scaled in bar, and a built-in reverse (check) valve that holds downstream settings when upstream pressure is lost. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.05 to 0.9 MPa (7-130 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 port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, a 40 um or optional 5 um (W) element, square or round gauges with MPa, psi or bar scales, G (BSPP) or NPT thread options, and bracket or no-bracket mounting. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and 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.

Installed on the 3/4 in main drop feeding a packaging hall, it strips water and pipe scale from the compressed air and sets a stable regulated pressure for the whole line, with the check valve holding the setting if supply pressure dips.
Mounted ahead of the valve manifold on a conveyor system, it cleans the air reaching cylinders and clamps and lets maintenance set the working pressure the actuators were designed for, with the bar gauge giving a clear local reading.
Fitted at the workshop wall where 3/4 in air lines serve impact wrenches, grinders and test rigs, it removes moisture before it reaches the tools and gives technicians a regulated, gauge-monitored supply at each bench.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when the line diameter and expected air demand point to the top of the family; smaller sizes (200/300/400) step down in port and flow capability. Choose the drain to match access: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl; automatic or differential-pressure drains suit unattended drops. The 40 um element is the standard grade; specify the 5 um W option only where finer pre-filtration is required. The square gauge here reads in bar; MPa and psi scales are also available, and an external round gauge is optional. Thread is NPT as coded, with PT (standard) and G (BSPP) as order options, and the bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm 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 family as curves rather than a single rated figure, so we do not quote a rated flow number. Send us your line size and air demand and we will confirm the sizing from the datasheet on request.
The M in the code GFR600C20MF3TK specifies a manual drain: the bowl is bled by hand, which suits installations that are visited regularly. If the drop is unattended, the same size 600 filter regulator can be ordered with an automatic (A) or differential-pressure (blank) drain instead.
