The AirTAC GFR40010MLJC1T 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 GFR40010MLJC1T is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air with a 40 um element, then regulates downstream pressure with its low-pressure type regulator. This configuration has 3/8 in NPT ports, a polycarbonate bowl with manual drain, a round MPa pressure gauge fitted, no mounting bracket and no reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of ports, threads (PT standard; G and NPT as order options), drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um with code W), gauge styles and scales, and bracket options. Flow is published as curves rather than a single rating, so we confirm flow and datasheet 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.
| GFR400 | G-series filter regulator, 400 body — sets the port range. |
|---|---|
| 10 | Port size PT3/8". 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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. |
| (blank) | No reverse-flow valve (the default). |
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 clean, regulated air to the cylinder and vacuum circuits of a carton-forming or wrapping line, where the manual-drain bowl suits a station visited on every shift.
Supplying filtered, pressure-regulated air to a bench-mounted pneumatic press or clamping fixture, with the round MPa gauge giving the operator a clear set-point readout.
Conditioning air for sorter divertors and stop-gate cylinders on a distribution conveyor, where the low-pressure type regulator suits circuits set well below full line pressure.
Start with the port step: this unit is size 400 with 3/8 in NPT ports; smaller and larger sizes (200/300/600) step port size and flow capacity up or down, so match the size to the air demand of the circuit. Choose the drain type to suit access: manual drain (this unit) needs an operator to drain the bowl, while automatic and differential-pressure drains discharge condensate without attention. Filter grade is 40 um standard; specify 5 um (code W) where finer particulate removal is needed. Gauge scale can be MPa, psi or bar, and the round external gauge on this unit can be swapped for the embedded square gauge style. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. Bracket: this configuration is supplied without a bracket; a bracket can be specified.
One honest routing note: flow for this family is published as curves, not a single rated figure, so 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 GFR family 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 unit on request before you order.
The M in the code specifies a manual-drain bowl: condensate is released by operating the drain by hand, which suits stations that are checked regularly. The GFR400 series is also available with automatic or differential-pressure drains as catalogue options - just order the corresponding code.
