The AirTAC GFR400C15MJC2TK AirTAC Filter Regulator NPT1/2 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 See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR400C15MJC2TK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a 1/2 in NPT port, a manual-drain bowl with a 40 um standard filter element, a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a round external gauge reading in psi. A reverse/check valve is fitted, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in and PT, G (BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi) and operating temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 0.15 - 0.9 MPa (20 - 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.

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.

Feeds clean, regulated air to the tool-change and clamping circuits of a CNC machining centre, with the 40 um element catching water and swarf-carried particulate before the valves. The manual drain suits a shop where an operator walks the machines daily.
Sits upstream of the cylinder and gripper manifold on a carton packaging line, holding a steady set pressure for consistent sealing and case-eject strokes. The 1/2 in port matches the main drop feeding the line, and the psi gauge lets maintenance read the setting at a glance.
Used at department-level take-off points on a factory ring main, filtering and regulating the branch supply before it splits to individual workstations. The fitted check valve holds the branch setting if the main dips, and the manual drain is handled on the weekly round.
Size 400 with a 1/2 in port sits in the upper-middle of the GFR range; step up to size 600 or down to 300 depending on the flow your line needs, and confirm the choice against the published flow curve with us before ordering. The manual drain on this unit means someone drains the bowl on a routine basis; automatic or differential-pressure drains are available if you want unattended drainage. The 40 um element is the standard grade; specify 5 um (code W) where finer filtration is needed. The round psi gauge is fitted here; embedded square gauges with MPa, psi or bar scales are the alternative. Thread is NPT on this model; PT is the standard and G (BSPP) is also an order option. A mounting bracket can be added if you need one (this unit ships without). Flow for this family is published as curves, not a single rating, 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 series as curves rather than a single rated figure, so there is no one rated flow number we can quote for this 1/2 in, size 400 unit. Send us your required flow and working pressure and we will confirm the sizing against the datasheet curve before you order.
The M in the code GFR400C15MJC2TK specifies a manual drain: the bowl is emptied by hand on a routine you set. If you prefer unattended drainage, the same unit can be ordered with an automatic drain (code A) or the default differential-pressure drain; the manual-drain version also carries the wider 0.05-0.9 MPa (7-130 psi) regulation range.
