The AirTAC GFR400-15MC1TK 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 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 GFR400-15MC1TK is a size 400 filter regulator that 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 40 um filter element, a manual drain on the polycarbonate bowl, an external round pressure gauge scaled in MPa, a built-in reverse/check valve, and a mounting bracket. The manual-drain regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum inlet pressure is 1.0 MPa (145 psi). Operating temperature 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 port sizes from 1/8 in to 1 in, a choice of manual, automatic or differential-pressure drains, a 40 um standard or 5 um (code W) element, square or round gauges with MPa, psi or bar scales, PT, G or NPT threads, and bracket options. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow figures for your application 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. 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.

| 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. |

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-clamp and chip-clearing circuits of a CNC machining centre, with the 1/2 in port handling the cell's main air drop and the manual drain bled at shift start.
Sits at the head of a carton-sealing or case-packing conveyor line, filtering line water and holding steady regulator pressure to the pick-and-place and clamp cylinders that index the product.
Installed as the point-of-use unit on a factory air drop serving pneumatic assembly fixtures, where the 40 um element protects valve spools and the check valve holds downstream pressure if the main supply dips.
Start with the size and port: the 400 series steps up in flow capacity and port size from the 200 and 300 series, so match the 1/2 in NPT connection here to your line size and expected air demand. Next, choose the drain: this unit has a manual drain, which suits installations where an operator can bleed the bowl on a routine basis; automatic or differential-pressure drains suit unattended duty. The 40 um element is the standard grade - specify the 5 um W option only where downstream equipment needs finer filtration. Gauge choices are the embedded square gauge or this external round gauge, with MPa, psi or bar scales. Thread is NPT here; PT is the catalogue standard and G (BSPP) is also an order option. A bracket is included on this unit.
One honest note on sizing: AirTAC publishes flow for the GFR series as curves, not as a single rated number, so we do not quote a flow figure here. Ask us to confirm the datasheet and check the curve against your application before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as performance curves rather than a single rated figure, so we do not quote a flow number for this unit. Contact us and we will confirm the datasheet and check the size 400 curve against your air demand before you order.
The M in the code GFR400-15MC1TK specifies a manual drain, which an operator opens periodically to bleed accumulated water from the polycarbonate bowl. If the unit will run unattended, the same GFR400 size is available with an automatic drain (code A) or the default differential-pressure drain.
