The AirTAC GFR30010MJC2TK AirTAC Filter Regulator NPT3/8 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 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 GFR30010MJC2TK is a 300-size filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a 3/8 in NPT port, a manual drain bowl in polycarbonate, a 40 um standard filter element, a round pressure gauge reading in psi, and a built-in reverse (check) valve that holds the set pressure if the upstream supply drops. It ships without a mounting bracket, so plan for direct piping or add a bracket if panel mounting is needed.
This is a genuine AirTAC part from the GFR300 series. The GFR line spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, and choices of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT threads, and bracket or no bracket. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures against 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 0.05 - 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.

|---|---|
| 10 | Port size PT3/8". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Clean, regulated air to the clutch and counterbalance circuits of a small punch press, with the check valve holding set pressure through momentary supply dips and the psi gauge letting setters verify settings at a glance.
Air preparation for the diverter and stopper cylinders on a carton packaging conveyor, where the 40 um element protects directional valves from water and debris and manual drain suits a shift-based maintenance routine.
Point-of-use regulation at an assembly cell drop feeding air tools and clamps, with the round psi gauge letting each operator confirm line pressure and the check valve preventing backflow between drops.
Size the unit by the port and flow step: 300 size with a 3/8 in NPT port sits mid-range in the GFR line, and stepping up to 400 or 600 buys more flow capacity at the cost of space. Drain type is a real decision here: this unit is manual drain, meaning someone must bleed the bowl periodically; automatic or differential-pressure drain versions remove that task if the installation is unattended. Filtration is the 40 um standard element; choose the W code for 5 um if downstream valves or instruments need finer protection. The gauge on this unit is the round external type reading in psi; embedded square gauges and MPa or bar scales are the other catalogue options. Thread is NPT on this code, with PT (standard) and G also available to order. Bracket is omitted on this configuration.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated figure, so we cannot quote a number here. Send us your flow and pressure requirements and we will confirm the correct size from the datasheet before you order.
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 performance curves rather than a single rated figure, so we do not quote a number here. Tell us your required flow and working pressure and we will confirm from the datasheet whether this 300-size unit with a 3/8 in NPT port suits your application before you order.
The M in the code means the polycarbonate bowl is drained by hand: someone opens the drain to expel collected water and contaminants. Choose manual where the unit is inspected on a regular maintenance schedule; choose the automatic or differential-pressure drain codes instead if the installation runs unattended and you want condensate removal without operator action.
