The AirTAC GFR40015MC2K AirTAC Filter Regulator, PT1/2, 40 um 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 GFR40015MC2K 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 PT1/2 (1/2 in) port, a manual drain bowl in polycarbonate, the standard 40 um filter element, a round external gauge with a psi scale, a fitted reverse/check valve, and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator adjusts from 0.05 to 0.9 MPa (7-130 psi), and the operating temperature range 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 a choice of port, thread (PT standard, G and NPT as order options), drain type, filter grade (40 um standard, 5 um with code W), gauge style and scale, and reverse/check valve. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |

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 filtered, regulated air to a pneumatic press or clamping fixture on a metal-forming line, where the 1/2 in port matches the main drop and the psi gauge lets operators set and verify working pressure at the cell.
Conditions the air feeding cylinders and diverters on a carton packaging conveyor, with the 40 um element catching pipe scale and the manual drain letting maintenance clear condensate during scheduled checks.
Supplies regulated air to gripper and tool-change circuits in a robotic welding cell, where the check valve holds the set circuit against backflow and the bracket gives a tidy panel-mounted installation.
Start with the size and port: the 400 size with its PT1/2 connection suits lines plumbed at 1/2 in, and larger sizes carry larger ports and more flow. Choose the drain type for the bowl: manual drain (this unit, code M) needs periodic draining by hand, while automatic and differential-pressure drains discharge condensate without operator attention. Choose the filter grade: 40 um is standard for general air prep, and 5 um (code W) is the finer option. Pick the gauge style and scale - embedded square or external round, in MPa, psi or bar. Thread is PT as standard; G (BSPP) and NPT are order options. A reverse/check valve (code K, fitted here) and a mounting bracket can be specified. Flow 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. 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 we do not quote one number. Tell us your application and we will confirm the flow and sizing data from the datasheet on request before you order.
M is the manual-drain code: condensate collected in the polycarbonate bowl is drained by hand, which suits lines with regular maintenance rounds. The trailing K means a reverse/check valve is fitted, and C2 specifies the external round gauge with a psi scale. With a manual drain, the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
