The AirTAC GFR60020MLF2WTK AirTAC 3/4 in NPT Filter Regulator is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60020MLF2WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus downstream pressure regulation combined in one body. This 600-size unit is threaded NPT3/4 (3/4 in NPT), carries a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, an embedded square gauge reading in psi, and a built-in reverse/check valve. The regulator is the low-pressure type; its exact adjustment range is not published, so confirm it against your set pressure before ordering. 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 series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT (standard), G and NPT threads, with differential-pressure, automatic or manual drains, 40 um or 5 um elements, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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 a paint-shop spray booth: the 5 um element strips water and particulate before the low-pressure regulator holds a steady setting for the atomising air, with the psi gauge giving operators a visible setpoint.
On a pilot-plant skid, the manual-drain aluminium bowl lets technicians bleed accumulated condensate at shift end, while the built-in check valve holds the downstream setting if the upstream supply dips.
A packaging line's pneumatic cylinders and actuators draw clean, regulated air from a 3/4 in supply; the low-pressure regulator type suits circuits set well below full line pressure.
Step through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this unit is the 600 size on a 3/4 in NPT thread. Choose the drain: differential-pressure (default), automatic (A) or manual (M, as here) - manual suits installations where an operator can bleed the bowl on a schedule. Choose the element: 40 um standard or 5 um (W) for finer protection. Gauge scales are MPa, psi or bar, embedded square as standard with an optional external round gauge. Thread is PT as standard; G and NPT are order options - this unit is NPT. A mounting bracket is included. Flow is published as curves, not a single rating, so 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
Flow for the GFR600 series is published as curves, not a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm from the AirTAC datasheet whether this 3/4 in NPT unit is correctly sized for the job.
M is the manual drain: you bleed the aluminium alloy bowl by hand rather than relying on the differential-pressure (default) or automatic (A) drain. L marks the low-pressure regulator type; its exact adjustment range is not published, so confirm your set pressure with us before ordering. The unit also carries a reverse/check valve (K) and a square gauge reading in psi (F2).
