The AirTAC GFR600-25 AirTAC Filter Regulator, NPT1, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size 600 unit is fitted with a 1 in NPT port, a 5 um filter element (the finer of the two available grades), a manual drain for emptying the bowl, an embedded square gauge scaled in MPa, and a reverse/check valve that holds downstream pressure when the supply is lost. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The regulation range for this manual-drain configuration is 0.05-0.9 MPa (7-130 psi). The aluminium alloy bowl on this size 600 unit suits installations where a polycarbonate bowl is not preferred.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge and scale options, an optional low-pressure regulator type, and G or NPT thread variants. Flow is published as curves rather than a single rating, so we confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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.

Installed at the main air drop feeding a CNC machining cell, it cleans water and particles from the compressed air and holds the header pressure setpoint the cell's valves and actuators were sized for.
Mounted ahead of the cylinder and valve bank on a packaging conveyor line, it conditions the air and regulates the supply pressure so clamp and pusher strokes stay consistent shift after shift.
Placed upstream of pneumatic grippers and sample-handling actuators in a laboratory automation system, the 5 um element provides finer filtration and the check valve holds the set pressure during supply dips.
Choose the size 600 / 1 in port step when your line's required flow sits above what the smaller 200-400 frames serve; because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. This unit is already configured with the 5 um element (choose 40 um instead when only coarse water and particle removal is needed), a manual drain (simple and positive, but it must be drained by an operator; automatic or differential-pressure drains suit unattended lines), a square MPa gauge (psi and bar scales are available), and a reverse/check valve. The thread here is NPT; PT is the standard and G (BSPP) is an orderable variant. A mounting bracket is included.
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 GFR flow as curves rather than a single rated figure, so we do not quote a flow, Cv or SCFM number. Tell us your line's flow demand and pressure and we will confirm the sizing against the datasheet on request before you order.
The manual drain means an operator opens the drain to empty collected water, which suits attended installations; automatic and differential-pressure drain versions are available in the same family for unattended lines. This unit carries the 5 um element (code W); the standard grade is 40 um, and both are selectable when ordering.
