The AirTAC GFR600C25ALC1TK AirTAC Filter Regulator NPT1 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 GFR600C25ALC1TK is a size-600 filter regulator: it removes water and particulate from compressed air and holds a steady downstream pressure in one body, so no separate filter and regulator pair is needed. This configuration is the low-pressure type with a 1 in NPT1 port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, and a metal bowl (size 600 bowls are aluminium alloy). It ships as coded with a round external MPa gauge, a reverse/check valve fitted, and the mounting bracket included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of thread (PT standard; G and NPT as order options), drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with code W), gauge style and scale, and reverse valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow data for your application 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. 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.

Weaving and spinning lines that run air nozzles and jets at reduced setpoints use the low-pressure GFR600 to clean the supply of water and lint-scale particulate while holding a stable, gentle pressure at the frame.
At a spray-booth air drop, the unit strips water and 40 um particulate ahead of the regulator section so guns and air motors see clean air at a steady low setpoint, with the automatic drain clearing condensate between shifts.
On a bottling hall conveyor section, cylinder-driven gates and pushers need clean air at a consistent low pressure; the 1 in port feeds the whole section and the check valve holds the circuit if the main supply dips.
Start with the size and port: this is the largest GFR frame (600) with a 1 in port, matched to lines with high air demand; smaller frames (200/300/400) cover lighter duties. Because this is the low-pressure type (code L), it suits circuits regulated well below standard mains pressure - confirm the setpoint range for your application with us before ordering. The automatic drain (code A) suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives in the family. The 40 um element is the standard grade; specify W for the 5 um option if downstream equipment needs finer filtration.
Other decodable choices: the round gauge here reads in MPa (scales 1/2/3 = MPa/psi/bar); the K code means a reverse/check valve is fitted to hold downstream pressure if the supply drops; the T code gives NPT thread (PT is the AirTAC standard, G/BSPP is also available); and the bracket is included. Flow is published as curves, not a single rating, so please 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 G-series flow as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number for this unit. Ask us to confirm the datasheet and flow curves for the GFR600 at your operating conditions and we will send them before you order.
The A code fits the automatic drain: the bowl ejects collected condensate on its own, which suits unattended or hard-to-reach installations where a manual or differential-pressure drain would be neglected. The K code means a reverse/check valve is fitted, holding downstream pressure if the upstream supply is lost. This unit also carries the L code, so it is the low-pressure regulator type - confirm the setpoint range for your circuit with us.
