The AirTAC GFR60025MLF2GK AirTAC Filter Regulator G1 Low-Pressure 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 PT1" 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 AirTAC GFR60025MLF2GK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1 (1 in) port with G (BSPP) thread, a manual drain, the standard 40 um filter element, a low-pressure regulator type, an embedded square gauge reading in psi, a fitted reverse/check valve, and an included mounting bracket. As a size-600 unit, its bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with a choice of drain type, 40 um or 5 um (W) filtration, gauge scale, thread (PT standard; G and NPT to order) and bracket option. Flow is published as curves rather than a single rating, and the exact regulation range of the low-pressure type is not stated on the datasheet - we confirm both on request 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. 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.

|---|---|
| 25 | Port size PT1". 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. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) 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.

On a paint finishing line, atomizing and blow-off nozzles are often run at a deliberately low setpoint. This low-pressure type filter regulator cleans the supply, holds the reduced setting, and the manual drain lets an operator clear accumulated condensate at the end of a shift.
Carton sealers, case erectors and label-head cylinders on a packaging conveyor need clean, gently regulated air. The 40 um element keeps debris out of directional valves, the square psi gauge gives operators a visible setpoint, and the 1 in G-thread port suits a main drop leg.
Pneumatic clamps and fixtures on a machining cell benefit from a low, stable pressure so workpieces are not over-clamped. The fitted reverse/check valve helps guard the circuit when supply pressure dips, and the manual drain supports a simple end-of-day moisture routine.
Size and port set the air capacity: the GFR family steps through 200, 300, 400 and 600, and within size 600 the port codes run 20 (3/4 in) to 25 (1 in). Match the step to the flow your line needs, then choose the drain: differential-pressure (default), automatic (A) or manual (M, as here). Filter grade is 40 um standard or 5 um with code W. Gauges are embedded square as standard with an optional external round gauge, scaled MPa, psi (code 2) or bar. Thread is PT as standard, with G (BSPP) and NPT as order options; brackets are optional (included on this unit) and a reverse/check valve is added with code K.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated figure, and the low-pressure regulator type's range is not stated as a number. Ask us to confirm both 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.
AirTAC publishes flow for the GFR series as curves rather than a single rated number, so we do not quote a l/min or SCFM figure. Tell us your line conditions and we will confirm the sizing from the datasheet curves on request. The same applies to the exact regulation range of the low-pressure type, which is not stated as a figure.
The M in the code GFR60025MLF2GK means the bowl drain is operated by hand, so someone opens it to release collected water. The GFR family also offers automatic drain (code A) and differential-pressure drain (the default, no code) if you would rather not rely on manual routines.
