The AirTAC AirTAC GFR400-15 Filter Regulator (GFR40015MLC1) 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 AirTAC GFR40015MLC1 is a low-pressure (L type) filter regulator: it filters water and particulate with the standard 40 um element and regulates downstream pressure at reduced set-pressure duties. This 400-size unit has PT1/2 ports, a manual drain bowl, a mounting bracket, and an external round gauge with an MPa scale so the set pressure is directly readable.
This is a genuine AirTAC part from the G series, which covers sizes 200 to 600 with drain, filtration and gauge choices. Max inlet pressure is 1.0 MPa (145 psi); working temperature is -5 to 70 C (non-freezing). Because this is the low-pressure type, confirm the applicable set-pressure range for your duty with us; flow figures are published as curves and we confirm datasheet values on request.

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.

|---|---|
| 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (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. |

| (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.

Regulates supply air at reduced pressure for air knife blow-off on a packaging or bottling line, with the MPa gauge letting operators verify the setting.
Filters and regulates low-pressure actuation air for tray-sealing and lidding machinery plumbed at 1/2 inch, with manual drainage in the sanitation schedule.
Supplies filtered, reduced-pressure air to adhesive dispensing benches, where the round gauge supports repeatable low-pressure setups between batches.
Select this code when the circuit runs at reduced pressure and you want a visible round gauge in MPa: the L type is the low-pressure variant, the manual drain suits attended drainage (automatic and differential-pressure drain codes exist), and the standard 40 um element is fitted (5 um is the W option). The 400 size with 1/2 inch PT ports suits higher-demand lines; step to 300/200 or 600 as needed. A mounting bracket is included under this code.
Ask us to confirm the low-pressure adjustment range and flow before ordering - AirTAC publishes flow as curves, not a single rating. PT is the standard thread; G (BSPP) and NPT are catalogue options to order.
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 as curves rather than a single rated figure, so we do not quote one number; send us your flow and pressure requirements and we will confirm the datasheet figures on request. As the L (low-pressure) type, its set-pressure range also differs from the standard version - we will confirm the exact range for your duty.
C specifies an external round pressure gauge (instead of the embedded square gauge), and 1 sets its scale to MPa. This code also carries L for the low-pressure type, M for the manual drain, and includes the mounting bracket. The filter grade is the standard 40 um element.
