The AirTAC GFR300C10MLC2T AirTAC Filter Regulator NPT3/8 Low-Pressure 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 GFR300C10MLC2T is an AirTAC GFR300 filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This configuration is the 300 size with a 3/8 in NPT thread, the standard 40 um filter element, and a manual drain you open by hand to expel collected condensate. It is the low-pressure type, intended for circuits that run well below standard line pressure, and it carries an external round gauge scaled in psi so the set pressure can be read directly. Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C (non-freezing). The bowl is metal, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and with choices of drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale (MPa, psi or bar), thread (PT standard, G and NPT as options) and bracket. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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 0.15 - 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.

Feeds filtered, reduced-pressure air to bagging or carton-sealing stations where delicate actuators and sealing jaws must run well below standard plant pressure, with the psi gauge letting operators verify the setting at a glance.
Supplies clean, regulated air to fixture clamps on a CNC cell, where the 40 um element keeps particulate out of the clamp cylinders and the low-pressure type holds a gentle, repeatable clamping force.
Conditions and steps down air for blow-off nozzles and product-guiding air jets along a conveyor line, with the manual drain emptied during routine line walks and the metal bowl standing up to daily plant service.
Start with size and port: the 300 size with a 3/8 in NPT port suits lines whose tubing and fittings step up from 1/4 in, but the right step depends on the flow your circuit needs - we can check it against the published curves. This unit has a manual drain, which is the right choice where someone walks the line routinely; if the point is inaccessible or unmanned, ask about the automatic or differential-pressure drain versions of the same size. The 40 um element is the standard grade for general plant air; a 5 um element (code W) is available if finer particulate removal is needed. The low-pressure type is selected where the working pressure sits well below standard regulator range - confirm the exact adjustment range with us. The round gauge here reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. PT is the standard thread and G or NPT are ordered as options - this unit is the NPT version. A bracket is included.
Because flow is published as curves and not as a single rated number, send us your application details and we will confirm sizing from 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 GFR series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and the air demand of your equipment, and we will confirm the sizing from the datasheet on request.
The M in the code is the manual drain: condensate collected in the metal bowl is released by opening the drain by hand, which suits points that are checked routinely. The L is the low-pressure regulator type, intended for circuits running well below standard line pressure; its exact adjustment range is not in the published table, so confirm it with us before ordering.
