The AirTAC GFR600C25MLC2GK 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 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 GFR600 series is a filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This unit is the size 600 configuration with a G1 (1 in) G-thread port, a manual drain on the aluminium alloy bowl, the standard 40 um filter element, and the low-pressure regulator type. It is fitted with an external round gauge reading in psi, a reverse (check) valve, and a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge and scale options, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm 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. 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.

Filtering and regulating the 1 in branch drop that feeds pneumatic impact tools and clamping fixtures at a vehicle assembly cell.
Conditioning supply air to the pneumatic cylinders and stopper gates that index and divert bottles along a filling and capping conveyor.
Supplying clean, regulated air to the quarter-turn pneumatic actuators that open and close process valves in a treatment plant.
Size and port step up with flow demand: 200 through 600, with this unit at the top of the range on a 1 in G thread. Because rated flow is published only as curves, ask us to check your air consumption against the GFR600 curve before ordering. This unit has a manual drain, so an operator opens the drain at intervals; choose the automatic (A) or differential-pressure (blank) drain codes if the unit will sit unattended. Filtration is the standard 40 um element; specify W for 5 um where finer particle capture is needed. The round gauge reads in psi (MPa and bar scales are alternatives), the thread is G (BSPP) with PT as the standard and NPT orderable, and the mounting bracket is included. As a low-pressure type, ask us to confirm the adjustment range against your set pressure.
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 GFR600 flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure and air consumption and we will confirm the datasheet flow curve for your application before you order.
The M in this code selects a manual drain: an operator opens the bowl drain at intervals to release collected water. If the unit will sit in an unattended location, the automatic (A) or differential-pressure (blank) drain codes are the alternatives to specify instead.
