The AirTAC GFR60025MLF2TK AirTAC Low-Pressure Filter Regulator 1 in NPT 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 GFR60025MLF2TK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 1 in NPT port, a manual drain bowl in aluminium alloy, a 40 um standard filter element, a low-pressure regulator type, an embedded square gauge scaled in psi, a built-in reverse/check valve, and a mounting bracket included.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with a choice of drain type, 40 um or 5 um (W) filtration, gauge scale, thread option and low-pressure or standard regulator type. Flow is published as curves rather than a single rated figure, so we confirm datasheet and sizing figures on request.

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. |
|---|---|
| 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. |
| 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.

Filter and hold a steady, lower supply pressure to the air cylinder circuit of a stamping or forming press, with the check valve holding downstream pressure if the feed dips.
Deliver cleaned, moisture-reduced air at a controlled low pressure to paint and coating guns, where a stable setting protects finish quality.
Feed filtered, regulated air to the grippers, clamps and diverters on a cartoning or palletising line running at high volume through a 1 in main.
Size 600 with a 1 in port is the largest step in the GFR range, so start there when the line demand is high and step down to 300/400 where it is not. Choose the drain to suit access: manual (this unit) for supervised points, automatic or differential-pressure where bowls are not checked daily. The 40 um element suits general plant air; specify 5 um (code W) for finer protection. The embedded square gauge here reads in psi; MPa and bar scales are also available. NPT is the thread on this unit; G (BSPP) and PT are the other catalogue options. A 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. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a number. Send us your line pressure and demand and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain, so condensate is released by hand at the bowl - a good fit where the unit is checked during routine rounds. At size 600 the bowl is aluminium alloy; smaller GFR sizes use a polycarbonate bowl. The regulator here is the low-pressure type, and we confirm its exact adjustment range from the datasheet on request.
