The AirTAC GFR30010MJF2W AirTAC Filter Regulator PT3/8, 5 um, psi gauge 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 PT3/8" 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 GFR30010MJF2W is a GFR-series filter regulator: it removes water and particulate from compressed air and sets downstream pressure in a single 300-size body with a PT3/8 (3/8 in) port. This configuration carries a 5 um filter element (the finer of the two catalogue grades), a manual drain on the PC (polycarbonate) bowl, and an embedded square gauge reading in psi. The standard regulator covers 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature is -5 to 70 C, non-freezing. No mounting bracket is fitted on this code.
This is a genuine AirTAC part. The GFR line is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, square or gauge options with MPa/psi/bar scales, 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.

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.

Feeds filtered, pressure-set air to tool changers, clamps and pneumatic cylinders on a machining centre. The 5 um element helps keep water and fine particulate out of precision valve stacks, and the psi gauge lets setters verify set pressure at the machine.
A drop point on a packaging line where carton sealers, case erectors and pick-and-place cylinders share one air supply. The filter regulator gives each line section its own clean, regulated pressure, and the manual drain suits a shift-based maintenance routine.
Supplies bench instruments, air bearings and test rigs that need clean air at a stable, repeatable pressure. The 5 um grade and square psi gauge make set-and-check straightforward, and the PT3/8 port drops into typical lab supply piping.
Start with the port step: this 300-size unit carries a PT3/8 (3/8 in) connection; step up to 400 or 600, or down to 200, if your line's flow demand sits on a different size. The 5 um element on this code suits air that feeds sensitive components; the 40 um grade is the standard choice for general actuator supply. The manual drain means an operator opens the bowl drain periodically - choose automatic or differential-pressure drain if you cannot schedule that. The square gauge here reads psi; MPa and bar scales are available, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are order options. This code ships without a mounting bracket - bracketed versions exist in the family.
Flow for this family is published as curves, not a single rating, so we cannot quote one number here. Send us your application's flow and pressure requirements and we will confirm the correct size against the AirTAC datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. 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 series as curves, not as a single rated number, so we do not quote a figure here. Tell us your required flow and working pressure and we will confirm the correct size against the datasheet on request before you order.
The M in the code selects the manual drain on the filter bowl: condensate is released by opening the drain by hand at intervals you set. If nobody can attend the unit regularly, the same 300-size body is available with automatic or differential-pressure drain instead - just ask for that code variant.
