The AirTAC GFR30010MC3TK AirTAC Filter Regulator NPT3/8 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 PT3/8" 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 GFR30010MC3TK is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This configuration is the 300 size with a 3/8 in NPT thread, a 40 um standard filter element, and a manual drain you operate by opening the bowl drain when needed. It is a standard-type regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi), a maximum inlet pressure of 1.0 MPa (145 psi), and a working temperature of -5 to 70 C (non-freezing). The round pressure gauge fitted here reads in bar, a reverse/check valve is fitted, and a mounting bracket is included. The polycarbonate bowl suits this 300 size (only the 600 size uses an aluminium alloy bowl).
This is a genuine AirTAC part. The GFR filter-regulator family spans the 200, 300, 400 and 600 sizes with ports from 1/8 to 1 inch, and offers automatic, manual or differential-pressure drains, a 5 um element option (code W), gauge scale choices, G/NPT thread options, and low-pressure variants. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application before ordering.

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.

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 a pneumatic press station: the 40 um element strips water and pipe scale before the air reaches directional valves and cylinders, while the regulator holds a steady working pressure for consistent clamping and forming strokes. The manual drain is emptied during scheduled operator rounds.
Filtered, regulated air for the pneumatic actuators on a bottling and capping machine. Clean, pressure-stable air keeps filler lift cylinders and capper heads moving repeatably through a shift, and the bar-reading gauge lets line staff verify set pressure at a glance.
Conditioning the air feed to a robotic welding cell's pneumatic grippers and torch-clean station. The check valve holds the regulated pressure against supply dips so parts are not dropped mid-cycle, and the included bracket mounts the unit neatly at the cell's air inlet panel.
Start by matching the size and port to the air demand of the machine: the 300 size with a 3/8 in NPT port sits in the middle of the GFR range, and the larger 400 or 600 sizes carry more flow. Choose the drain to suit access: this unit has a manual drain, which suits stations an operator visits anyway; automatic or differential-pressure drains suit unattended installations. The 40 um element fitted here is the standard grade; specify the 5 um W option where downstream equipment needs finer filtration. The round gauge on this unit reads in bar, and square embedded gauges or MPa/psi scales are alternatives. PT is the standard thread; G (BSPP) and NPT are order options, and this unit is ordered in NPT. A bracket is included, and the fitted check valve holds downstream pressure if upstream supply is interrupted. Because flow is published as curves rather than one rated figure, send us your application details and we will confirm the sizing against the datasheet before you order.
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 GFR flow as performance curves rather than a single rated figure, so we do not quote a number that could mislead your sizing. Tell us your application's air demand and inlet pressure and we will confirm the flow figures from the datasheet on request before you order.
The M in the code GFR30010MC3TK specifies a manual drain: condensate collected in the polycarbonate bowl is released by opening the drain when needed, which suits stations visited during normal maintenance rounds. If the installation is unattended, the same GFR300 series can be ordered with an automatic drain (code A) or the default differential-pressure drain instead.
