The AirTAC GFR400C15MC2WG AirTAC Filter Regulator G1/2, 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 GFR400C15MC2WG 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 5 um filtration element (one step finer than the 40 um standard), a manual drain for the bowl, a fitted external round gauge with a psi scale, and a G1/2 (BSPP) port with G thread. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and maximum working (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" to 1", and with choices of drain type, filter grade, gauge style and scale, thread (PT standard; G and NPT are order options) and bracket. 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 0.15 - 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.

Point-of-use conditioning for the pneumatic clamps, tool-change actuators and chip-clearing blasts on a machining centre: the 5 um element protects sensitive valves from finer particles while the regulator holds a steady setting for repeatable clamping force, and the psi gauge lets setters verify the line at a glance.
Conditioning and regulation for the diverters, pushers and sealing cylinders on a carton or bagging line. The manual drain suits a line that is bled down at shift start and end, and the round psi gauge gives operators a visible setpoint for consistent seal and pusher action.
Feeding a manifold of directional valves and gripper circuits on a robotic assembly cell, where finer filtration helps the pilot valves seat cleanly over long production runs. The regulator sets the circuit pressure for the grippers, and the included bracket fixes the unit to the cell frame next to the manifold.
Size 400 with a G1/2 port sits in the upper half of the GFR range; step up to size 600 or down to size 300 depending on the flow your line needs - ask us to check the published flow curves against your demand before ordering. Drain type is a real operating choice: this unit has a manual drain, which suits attended installations where an operator can bleed the bowl on a routine; automatic or differential-pressure drains suit unattended duty. The 5 um element (code W) is the finer of the two published grades (40 um standard, 5 um optional) - choose it where downstream valves and cylinders are sensitive to finer particles. Gauge options are the embedded square gauge or an external round gauge, with MPa, psi or bar scales; this unit carries a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options; this unit is ordered with G thread. A mounting bracket is included.
Because flow is published as curves rather than a single rating, we do not quote a rated flow number. Send us your application details and we will confirm the datasheet figures and correct sizing 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 the GFR series as curves, not as a single rated figure, so we do not quote a rated flow number for this unit. Tell us your port size, working pressure and air demand, and we will confirm the datasheet flow curve and check the sizing against your application on request.
The bowl that collects water and particles has to be emptied, and this unit uses a manual drain: an operator opens the drain at chosen intervals. Manual drain suits attended installations with a routine check, while automatic and differential-pressure drains suit unattended duty. If your compressor room or cell is not visited daily, ask us about the automatic-drain version of the same GFR400 unit.
