The AirTAC GFR300C15JC2T AirTAC Filter Regulator NPT1/2 with 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 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 GFR300C15JC2T is a size 300 filter regulator that cleans compressed air and sets downstream pressure in one body. The 40 um element removes water and particulate ahead of the regulator, the differential-pressure drain bleeds collected condensate automatically as flow passes through, and the outlet pressure is adjustable from 0.15 to 0.9 MPa (20-130 psi). This configuration is ordered with the external round gauge on a psi scale and without a mounting bracket, on a 1/2 in NPT port. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The polycarbonate bowl suits the 300 size frame.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um (code W) element option, gauge scale in MPa, psi or bar, G/NPT thread variants and optional brackets. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Feeding cleaned, regulated air to the cylinder circuit of a stamping or forming press, where the 40 um element protects valves from particulate and the regulator holds a set clamping pressure shift after shift.
Supplying pick-and-place and carton-sealing cylinders on a packaging conveyor, with the differential-pressure drain carrying off condensate during continuous running and the psi gauge giving operators a readable setpoint.
Conditioning the air drop serving bench-mounted test rigs and pneumatic fixtures in a laboratory, where the 1/2 in NPT port matches the header and the regulator lets each bench set its own pressure.
Size 300 with a 1/2 in port sits in the middle of the GFR range; step up to 400/600 or down to 200 depending on the flow your line needs, and confirm the match against the published flow curves with us before ordering. The differential-pressure drain on this unit suits steady-flow installations where condensate is carried away continuously; choose automatic drain (code A) for intermittent flow or manual drain (code M) where you want controlled purging and the wider 0.05-0.9 MPa adjustment range. The 40 um element is the standard grade; specify 5 um (W) only where downstream equipment demands finer filtration. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. Thread is NPT on this code, with PT (standard) and G (BSPP) available to order, and the J code means no bracket is supplied - add one if the unit will not be piped-supported.
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 GFR300 series as curves rather than a single rated figure, so we do not quote one number. Send us your inlet pressure, set pressure and required consumption and we will confirm the sizing against the datasheet curves on request before you order.
With no drain code in the model, the GFR300C15JC2T uses the differential-pressure drain, which passes condensate automatically whenever air flows through the bowl - no operator attention needed. If your application runs intermittently or you prefer controlled purging, the same size is available with automatic drain (code A) or manual drain (code M); note the manual-drain version also widens the regulation range down to 0.05 MPa.
