The AirTAC GFR40015MLC2T AirTAC Filter Regulator NPT1/2 Low-Pressure 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 GFR40015MLC2T is an AirTAC GFR400 filter regulator: filtration and pressure regulation combined in a single body. It removes water and particulate from compressed air through a 40 um element, holds downstream pressure steady, and vents condensate via the manual drain, which you open by hand as part of routine checks. This configuration is the low-pressure type, is fitted with an external round gauge reading in psi, includes a mounting bracket, and connects through 1/2 in NPT ports.
This is a genuine AirTAC part from the GFR400 size, one of four sizes (200, 300, 400, 600) in the G-series filter-regulator line, with port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drain, a 5 um element option, gauge scale choices, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details for 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. 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.

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 filtered, regulated air to the clamp cylinders on a workholding press, where the low-pressure regulator type holds a gentle, consistent clamp force cycle after cycle.
Mounted ahead of the actuator bank on a carton-sealing or case-packing conveyor, cleaning water and debris out of the supply while keeping the operating pressure steady for smooth jaw and pusher action.
Conditioning the air feeding sample-handling valves and small actuators on an automated laboratory bench, where the psi gauge gives operators a clear local pressure readout and the manual drain fits a supervised environment.
Start with the port step: this unit is the 400 size with 1/2 in NPT ports, so check that the flow your line needs sits comfortably within the GFR400 curve band - we will confirm against the datasheet curves on request. Drain choice matters: the manual drain fitted here suits installations where someone walks the line regularly; choose automatic or differential-pressure drain if the unit sits in an inaccessible spot. The 40 um element is the standard grade; specify the W code if you need the 5 um option. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are alternatives. NPT is the ordered thread option (PT is the catalogue standard; G/BSPP is also available), and the bracket is included on this code.
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 this series as curves, not as a single rated figure, so we do not quote a number. Send us your application's flow and pressure requirements and we will confirm against the GFR400 datasheet curves whether this 1/2 in unit is correctly sized before you order.
The M in the code specifies a manual drain: condensate collects in the PC bowl and is released by opening the drain by hand, which suits lines that receive regular walk-down checks. The same GFR400 size is also available with an automatic or a differential-pressure drain if your installation cannot rely on manual attention - just specify the corresponding drain code when ordering.
