The AirTAC GFR30008MJC2W AirTAC Filter Regulator PT1/4 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 PT1/4" 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 GFR30008MJC2W is a GFR300 filter regulator: filtration and pressure regulation combined in a single body, so one component removes water and particulate from the compressed air and holds a steady downstream pressure. This configuration is built around 1/4 in PT ports, a manual-drain bowl in polycarbonate, a 5 um filter element for finer particulate capture than the standard 40 um grade, and a round pressure gauge reading in psi. No mounting bracket is fitted, so plan to support the unit from the pipework or order a bracket separately.
This is a genuine AirTAC part. The GFR range is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, with G and NPT as order options) and bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the regulator on this manual-drain version adjusts from 0.05 to 0.9 MPa (7-130 psi). Flow is published as curves rather than a single rating, so ask us to confirm the 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 0.05 - 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.

Feeding a compact pneumatic press or clamping fixture: the 5 um element keeps fine particulate out of the press valve, the regulator holds the set clamping pressure, and the round psi gauge gives the operator a visible setpoint at the cell.
Supplying sealing jaws and carton-closing cylinders on a packaging conveyor: filtered, regulated air at a stable pressure keeps jaw action consistent through the shift, and the manual drain suits a line that is bled down during end-of-shift housekeeping.
Air supply for pick-and-place grippers and small cylinders at assembly stations: the filter and regulator in one body saves panel space at each station, and the psi gauge lets technicians verify the set pressure at a glance during changeover.
Choose the size by the flow your line needs: 200, 300, 400 and 600 step up in port and capacity, and this GFR300 sits at 1/4 in PT. Because AirTAC publishes flow as curves rather than a single rated figure, send us your air demand and we will confirm the sizing against the datasheet before you order. Drain type is a real decision: this unit has a manual drain, which suits points where an operator can bleed the bowl on a routine walk-round, while automatic and differential-pressure drains suit unattended installations. The filter grade here is 5 um (code W) against the 40 um standard - pick 5 um where downstream valves and cylinders are sensitive to fine particulate. The round gauge reads in psi; an embedded square gauge and MPa or bar scales are the alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order, and no mounting bracket is fitted on this version.
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 range as curves, not as a single rated figure, so we do not quote a number here. Send us your inlet pressure, required downstream pressure and air demand, and we will confirm the flow from the GFR300 datasheet for your application before you order.
This unit has a manual drain: condensate collected in the polycarbonate bowl is released by operating the drain when it is checked. The automatic drain (code A) and the differential-pressure drain (the default) discharge condensate without an operator, which suits unattended installations. Manual drain also gives the full regulator adjustment range of 0.05-0.9 MPa (7-130 psi).
