The AirTAC GFR40015MC2WK AirTAC Filter Regulator PT1/2, 5 um is a genuine G-series filter regulator: water separation, 5 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 GFR40015MC2WK is a filter regulator: one body removes water and particulate from compressed air and holds downstream pressure steady. This size 400 unit is threaded PT1/2 (1/2 in), fitted with a 5 um filter element, a manual-drain bowl in polycarbonate, a round gauge reading in psi, and a reverse/check valve. The regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), the unit accepts up to 1.0 MPa (145 psi) inlet, and it operates from -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part from the GFR400 series. The GFR line spans sizes 200 to 600 with ports from 1/8 to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um optional filtration, gauge and scale options, and G or NPT thread variants. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet 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 0.05 - 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 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.

Feeding spray guns on a finishing line, where clean, dry air at a set pressure keeps atomisation consistent; the 5 um element and manual drain suit a booth that an operator checks each shift.
Holding a steady clamping pressure to workholding cylinders on a CNC fixture, with the check valve helping hold the set pressure if upstream supply dips.
Regulating supply to sealing jaws and pick-and-place cylinders on a cartoning or wrapping line, with the 1/2 in port serving a machine header fed from the plant ring main.
Size the unit by port and required flow: this 400-size body carries PT1/2 (1/2 in), and the next size step up or down changes both port and flow capacity - we can confirm curve figures against your demand before you order. The manual drain means the bowl is emptied by hand, which suits installations someone already visits regularly; choose automatic or differential-pressure drain codes if the unit will be left unattended. The 5 um element (code W) gives finer protection than the 40 um standard where downstream valves and cylinders need it. The round gauge is scaled in psi; square embedded gauges and MPa or bar scales are alternatives in the series. PT is the standard thread here, with G (BSPP) and NPT available as order options, and a mounting bracket is included.
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 curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your line pressure, set pressure and air demand, and we will confirm the sizing from the datasheet curves before you order.
The polycarbonate bowl collects water and the 5 um element traps particulate, but with a manual drain the condensate must be emptied by hand - open the drain when the bowl is visibly loaded. If the unit sits in an unattended location, ask us about the automatic or differential-pressure drain versions of the same GFR400 unit.
