The AirTAC GFR300C10MC2WT AirTAC Filter Regulator 3/8 in NPT, 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 GFR300C10MC2WT is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 300 unit is supplied with a 3/8 in NPT port, a 5 um filter element (finer than the 40 um standard), a manual drain, a round psi gauge, a metal bowl and a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi), the regulation range is 0.05-0.9 MPa (7-130 psi), and the working temperature is -5 to 70 C (non-freezing).
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 including automatic, manual or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and full datasheet figures 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.

Clean, regulated air to spray guns: the 5 um element strips water and particulate that would spoil a finish, the regulator holds a steady gun pressure, and the manual drain is bled at shift changeover.
Steady regulated air to pick-and-place and carton-sealing cylinders along the line; the round psi gauge lets operators verify the setpoint at a glance during changeovers.
A filtered, regulated supply for gauges, actuators and test rigs where fine control matters; the manual drain suits attended, supervised setups that are bled between runs.
Step the size and port (200 to 600, 1/8 to 1 in) against the flow your line needs; this unit is size 300 with a 3/8 in NPT port. Choose the drain: manual (as here) needs periodic bleeding by hand, while automatic and differential-pressure drains handle condensate for you - note the regulation range differs by drain type, 0.05-0.9 MPa (7-130 psi) with a manual drain versus 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains. Filter grade is 40 um standard or 5 um (code W) for finer protection; this unit carries the 5 um element. Gauges are embedded square as standard with an optional external round gauge in MPa, psi or bar scales - a round psi gauge is fitted here. Threads come as PT (the standard), G (BSPP) or NPT, and brackets are optional across the family. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and full datasheet figures on request before you order.
This unit is specified with a manual drain: accumulated condensate is bled by hand at intervals you set. Automatic and differential-pressure drains are available in the same family if you prefer unattended operation - note the regulation range differs: 0.05-0.9 MPa (7-130 psi) with a manual drain versus 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drains.
