The AirTAC GFR40015MJF2WT AirTAC Filter Regulator NPT 1/2 in 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 PT1/2" 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 AirTAC GFR40015MJF2WT is a size-400 filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This configuration is threaded NPT 1/2 in, carries the fine 5 um filter element (code W), uses a manual drain on the bowl, and ships as a standard regulator with an embedded square gauge reading in psi. No reverse/check valve is fitted and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The regulation range for this manual-drain version is 0.05-0.9 MPa (7-130 psi). The polycarbonate bowl suits the 400 size; only the 600 size uses an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, embedded square or optional external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so we confirm datasheet and flow figures on request before you order.

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. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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.

Placed ahead of the pneumatic clamp cylinders on a CNC machining cell, it strips water and chips-laden condensate from the shop air and holds a steady clamp pressure so workholding stays consistent through the shift.
Mounted at the air drop feeding diverter and pusher cylinders on a parcel sortation conveyor, it cleans the supply and sets the operating pressure the gate actuators were designed around.
Installed on the branch line serving capper and cap-chute cylinders on a bottling line, it removes moisture that would gum the valve internals and regulates pressure for repeatable capping action.
Choose the size and port step against the air demand of the circuit: this unit is a size-400 body with a 1/2 in NPT port, one step up from the 300 series. The 5 um element (code W) is the finer choice over the 40 um standard element when downstream valves and cylinders need cleaner air. The manual drain means an operator opens the drain periodically instead of relying on an automatic or differential-pressure drain - pick automatic if the unit sits where regular draining is impractical. The fitted square gauge reads in psi; MPa and bar scales are available, and an external round gauge is optional. PT is the standard thread, with G and NPT as order options; this code is the NPT version. No bracket is included on this code, so plan a bracket if you want panel or wall mounting. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The M in the code specifies a manual drain: condensate collects in the polycarbonate bowl and an operator opens the drain valve periodically to remove it. Choose manual where the unit is accessible and drained on a routine; choose the automatic or differential-pressure drain option where the unit is hard to reach or the line runs unattended.
