The AirTAC GFR400C15MF2W AirTAC Filter Regulator PT1/2, 5 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 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 GFR400C15MF2W is a size-400 filter regulator that removes water and particulate from compressed air and sets downstream pressure in a single body. This configuration carries a PT1/2 (1/2 in) PT thread, a 5 um filter element for finer filtration than the 40 um standard, a manual drain bowl, and an embedded square gauge scaled in psi. 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 unit operates from -5 to 70 C (non-freezing). The polycarbonate bowl is fitted with a manual drain, and a mounting bracket is included.
This is a genuine AirTAC part in the GFR400 size range, with port sizes, thread options (PT standard, G and NPT to order), drain types, filter grades and gauge scales available across the family. Because flow is published as curves rather than a single rated figure, 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 0.15 - 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.

Feeding clean, regulated air to a machining centre's pneumatic tool clamps and actuators, with the 5 um element protecting fine valve internals and the psi gauge giving operators a direct setpoint readout.
Conditioning air for conveyor diverters and carton-forming cylinders on a packaging line, where the manual drain is bled during shift changeovers and the regulator holds a stable pressure for consistent cylinder stroke timing.
Serving a spray-booth air drop where finer 5 um filtration helps protect finish quality, and the regulator sets the lower, stable pressure that spray equipment and air-assisted applicators need.
Choose the size-400 / PT1/2 step when your line runs at 1/2 in porting and you want filter and regulator in one body instead of two components. Pick the 5 um element (this model) over the 40 um standard when downstream equipment needs finer particulate removal; the manual drain suits installations where an operator can bleed the bowl on a routine, while automatic and differential-pressure drains are the alternatives for unattended duty. The embedded square gauge here reads in psi; MPa and bar scales and an external round gauge are options. PT is the standard thread, with G (BSPP) and NPT as order options, and a bracket is included.
Flow for this family is published as curves, not a single rating, so send us your application conditions and we will confirm sizing against the datasheet before you order.
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 family as curves rather than a single rated figure, so we do not quote a number. Send us your application conditions and we will confirm the flow curve and sizing from the datasheet on request.
The M in the code specifies a manual drain bowl: condensate is released by operating the drain by hand. It suits installations with routine operator presence; choose automatic or differential-pressure drain versions where the unit runs unattended.
