The AirTAC GFR600C25MNWTK AirTAC Filter Regulator NPT1 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 GFR600C25MNWTK is a filter regulator: one body that removes water and particulate from compressed air and sets downstream pressure. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (the fine grade, in place of the standard 40 um), a manual drain on the bowl, and a reverse/check valve that holds the downstream circuit against backflow. The 600-size bowl is aluminium alloy. No gauge is fitted with this code, so add a gauge separately if a visual pressure reading is needed. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjustment range with manual drain is 0.05-0.9 MPa (7-130 psi), and the working temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Dropping a 1 in NPT filter regulator at the header feeding a press-shop air ring cleans the supply of water and scale and lets maintenance set a fixed working pressure for the press controls, with the check valve holding the circuit during upstream dips.
A dedicated filtered and regulated supply to the pneumatic tool-changer and clamping circuits on a machining centre: the 5 um element protects the pilot valves from fine particulate, and the regulator pins the pressure the machine builder specifies.
Feeding the cylinders and air bells that run a carton-sealing or palletising conveyor: one unit filters the plant air, sets the pressure that governs conveyor speed and gentle product handling, and the manual drain suits a line that is bled at shift start.
Start with the port and size step: size 600 with a 1 in port is the largest GFR frame, so match it to the pipe diameter and the air demand of the circuit. Choose the drain to suit access: this code carries a manual drain, which suits attended installations where an operator can bleed the bowl; automatic or differential-pressure drains suit unattended lines. The 5 um element (code W) is the finer grade versus the standard 40 um - pick it where downstream equipment needs cleaner air. Gauge, scale (MPa, psi or bar) and thread variant (PT standard, G or NPT to order) are decodable choices, and the bracket is included on this code.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application details and we will confirm the sizing against the datasheet curves before you order.
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 flow for the GFR family as performance curves rather than a single rated figure, so we do not quote a flow number here. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing against the datasheet curves on request.
The M in the code selects a manual drain: the bowl is bled by hand, which suits installations where an operator is present regularly; automatic and differential-pressure drains are available on other codes for unattended lines. The N means no gauge is fitted, so order a gauge separately (round or square, with MPa, psi or bar scale) if you want a visual pressure reading.
