The AirTAC GFR400C15LC2WK 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 GFR400C15LC2WK is a size 400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1/2 in PT port, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, a differential-pressure drain that bleeds accumulated condensate automatically whenever the pressure differential across the element is high enough, and a reverse/check valve (code K) that holds the downstream circuit when upstream pressure is lost. It is the low-pressure type and carries a round external gauge with a psi scale; a mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of drain types, 40 um or 5 um filtration, gauge styles and scales, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rating, so we confirm the datasheet and sizing 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.

On a stamping or assembly press with air-operated clamps, this unit filters the supply to 5 um to protect valve spools and cylinders, regulates the clamp circuit at low pressure, and the check valve holds the clamps if the upstream feed drops.
Feeding carton sealers, diverters and wrap stations on a packaging conveyor, the unit conditions the 1/2 in main supply, keeps condensate out of the actuator circuit via the differential-pressure drain, and lets operators read line pressure in psi.
On filling and capping machines where finer air quality helps keep ejectors and gripper valves clean, the 5 um element and low-pressure regulation suit the gentler actuator circuits, while the included bracket allows tidy mounting beside the machine.
Start with the port step: this unit is a size 400 with a 1/2 in PT port, one step up from the 3/8 in size 400/10 variant and below the 3/4 in size 600, so match the size to the air demand of the circuit - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. The 5 um element (W) suits circuits that need finer particulate removal than the standard 40 um grade; the differential-pressure drain needs no manual attention but the same series offers automatic (A) and manual (M) drains if your duty cycle calls for them. This is the low-pressure type (L) for circuits that run below standard regulator settings - the exact adjustment range for this variant is not published, so confirm it with us. The round psi gauge is fitted as coded; embedded square gauges and MPa or bar scales are the other catalogue choices. PT is the standard thread here, with G (BSPP) and NPT available as order options, and the included bracket simplifies panel or wall mounting.
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 series as curves rather than a single rated figure, so we do not quote a number. Tell us your application and we will confirm the flow curve and correct sizing from the datasheet on request.
W is the 5 um filter grade, one step finer than the 40 um standard element, and C2 codes the fitted external round gauge with a psi scale. The same series can be ordered with the 40 um element, an embedded square gauge, or MPa or bar scales if you prefer.
