The AirTAC GFR300C10ALC2WTK AirTAC Filter Regulator, NPT3/8, 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 GFR300C10ALC2WTK is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at your setpoint. This configuration is built on the size 300 body with a 3/8 in NPT port, a 5 um filter element (finer than the 40 um standard), an automatic drain that expels collected condensate without manual attention, and the low-pressure regulator type. It is rated for a maximum inlet pressure of 1.0 MPa (145 psi) and -5 to 70 C operation, and it is supplied with a round external gauge scaled in psi, a reverse/check valve, a mounting bracket, and a metal bowl.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options that include manual, automatic or differential-pressure drains, 40 um or 5 um filtration, standard or low-pressure regulation, square or round gauges scaled in MPa, psi or bar, PT, G or NPT threads, and bracket choices. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 0.15 - 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 filtered, regulated air to the pneumatic cylinders on a carton-sealing or case-packing conveyor, where the 5 um element protects the directional valves and the automatic drain keeps condensate out of the line during continuous runs.
Supplying clean, stable low-pressure air to the gripper and vacuum-generator circuits of a robotic pick-and-place cell, with the round psi gauge letting technicians verify the setpoint right at the panel.
Holding a gentle, stable supply pressure for the air-actuated fill and capping valves on a bottling line, where the low-pressure regulator type and automatic drain suit long, unattended production shifts.
Within the GFR range you step up through sizes 200, 300, 400 and 600 as your port and flow demand grows; this unit is size 300 with a 3/8 in NPT port. Drain choice matters: automatic (as fitted here) suits unattended duty, manual drain puts discharge in the operator's hands, and the differential-pressure default drains on a pressure drop. Filtration is 40 um standard or 5 um (code W, as here) for finer protection. The low-pressure type (code L) is selected when your setpoint sits below the standard regulator's range; ask us to confirm the exact adjustment range for your setpoint. Gauges come as the embedded square type or an external round gauge, scaled in MPa, psi or bar; threads can be ordered in PT (standard), G or NPT. Because AirTAC publishes flow as curves rather than a single rated figure, send us your flow and pressure requirements 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 the GFR300 as performance curves rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the sizing from the datasheet before you order.
The W code fits a 5 um element instead of the 40 um standard, giving finer protection for downstream valves, cylinders and instruments. The A code adds an automatic drain, so collected condensate is expelled without manual attention - useful where the unit is mounted in a panel or another awkward spot. Both are catalogue options across the GFR range.
