The AirTAC GFR30008JC2K AirTAC Filter Regulator PT1/4, 40 um, psi Gauge 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 PT1/4" 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 GFR30008JC2K is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in one body. It carries a 1/4 in PT port, a 40 um standard filter element and a differential-pressure drain that bleeds collected condensate automatically whenever the pressure drop across the bowl reaches its trigger point, so there is no manual drain routine. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round gauge on a psi scale is fitted so operators can read and set pressure directly. A reverse/check valve is included, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in and thread choices of PT (standard), G and NPT. The polycarbonate bowl suits this 300 size (600-size bowls are aluminium alloy), maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published in the catalogue as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

Cleaned and pressure-set air for a machining centre's pneumatic tool clamps and chip-suction actuators, with the psi gauge letting the setter dial in the clamp pressure at the machine.
Point-of-use air preparation for a carton-sealing or wrapping machine, where the filter-regulator keeps water and debris out of the sealing cylinders and holds a stable working pressure shift after shift.
Conditioned air ahead of a solenoid-valve manifold on an assembly fixture, with the check valve holding the set pressure against backflow when the upstream supply dips.
Start with the port step: this unit is the 300 size on a 1/4 in PT thread, so match it to the line size and the air demand of the equipment it feeds - larger sizes (400, 600) move more air through larger ports. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order. The 40 um element on this unit is the standard grade; if you need finer filtration, the 5 um W-grade option is available in the family. The differential-pressure drain is the fit-and-forget choice; automatic (A) and manual (M) drain variants exist if your installation prefers them. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread here, with G and NPT available to order, and a mounting bracket can be added if the J (no bracket) version needs one.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves in the catalogue, not as a single rated number, so we do not quote a figure here. Tell us your line size and air demand and we will confirm the flow data from the datasheet for this 300-size, 1/4 in unit before you order.
This configuration has a differential-pressure drain, which discharges collected condensate automatically when the pressure drop across the bowl reaches its trigger level, so no routine draining is needed. If your installation suits it, the same 300-size filter regulator is also available with an automatic (A) or manual (M) drain - just ask for the matching code.
