The AirTAC GFR40015MJF2TK AirTAC Filter Regulator 1/2 in NPT 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 PT1/2" 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 GFR40015MJF2TK is an AirTAC GFR400 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration takes a 1/2 in NPT port, uses a manual drain on the polycarbonate bowl, carries the standard 40 um filtration element, and is fitted with an embedded square gauge reading in psi. A reverse/check valve is included and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, with manual, automatic or differential-pressure drains, 40 um or 5 um elements, and gauge choices. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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.

|---|---|
| 15 | Port size PT1/2". This body offers 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. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. 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.

Point-of-use conditioning for a CNC machining cell: filtered, regulated air to the tool changer, clamps and pneumatic actuators, with the psi gauge giving the operator a local setpoint readout at the machine.
Mounted at the drop from a packaging line's air header to feed case packers and carton sealers, with the reverse/check valve helping hold the downstream setting if the main supply dips.
Clean, stable air to laboratory test rigs and pneumatic fixtures, with the manual drain letting technicians blow down the bowl as part of the start-of-shift routine.
Size 400 with a 1/2 in NPT port is the step to take when your line's flow demand sits above what a 300 unit comfortably handles; step up or down through 200/300/400/600 to match the application. Because AirTAC publishes flow as curves rather than a single rated figure, ask us to confirm sizing against your flow and pressure requirement before ordering. The drain on this unit is manual, so plan a routine blow-down; automatic and differential-pressure drains are available in the same family if you would rather not rely on operator rounds. The 40 um element is the standard grade, and a 5 um element (code W) is offered where finer filtration is needed. The embedded square gauge reads in psi, with external round gauges and MPa or bar scales orderable. G (BSPP) and NPT threads are catalogue options alongside the PT standard, and a mounting bracket can be specified if this no-bracket version does not suit your panel.
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 GFR400 as curves rather than a single rated figure, so we do not quote a number here. Send us your required flow and working pressure and we will confirm from the datasheet whether this 1/2 in NPT size suits your application.
The M in the code sets a manual drain, so the bowl is emptied by hand on a routine; automatic and differential-pressure drains are available in the same family. The K fits a reverse/check valve, which helps hold the downstream condition if the upstream supply is interrupted. The embedded square gauge on this unit reads in psi, and MPa or bar scales can be ordered.
