The AirTAC GFR300C08MLJC2T AirTAC Filter Regulator NPT1/4 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.
GFR300C08MLJC2T is an AirTAC GFR300 filter regulator: water and particulate filtration plus pressure regulation in a single body. This configuration takes a 1/4 in NPT port, is the low-pressure regulator type, and carries a manual drain, a 40 um filter element, a metal bowl and a round pressure gauge reading in psi. No reverse/check valve is fitted and no mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and the catalogue offers drain choices, a 5 um (W) filter grade, alternative gauge scales and G or NPT thread options. Because AirTAC publishes flow as curves rather than a single rated figure, we confirm flow and datasheet figures 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.

Point-of-use filtering and regulation for the gripper circuit on a robotic pick-and-place cell, with the round psi gauge for local setpoint checks at the cell.
Clean, regulated air ahead of a machine's pneumatic valve manifold, with the manual drain opened at shutdown to clear accumulated condensate.
Filtered, regulated air for cylinder-driven tucking and sealing heads on a cartoning line, with the metal bowl guarding against splash and debris in the plant environment.
Size and port: the 300 size steps up from 200 for larger ports and higher flow; this unit is 1/4 in NPT (PT is the standard thread, with G and NPT as order options - match the thread to your fittings). Drain: manual (M) suits lines that are blown down at shutdown or service intervals; automatic (A) and differential-pressure (blank) versions are catalogue alternatives in the same size. Filter grade: 40 um standard here, 5 um with code W for finer protection. Gauge: this unit has the external round gauge with a psi scale; embedded square gauges and MPa or bar scales are options. Regulator type: low-pressure (L) - confirm the setpoint range against your circuit before ordering. Bracket: not fitted (J).
Flow is published as curves, not a single rating, so 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 GFR300 flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow and sizing from the datasheet on request.
The M in the code selects a manual drain: condensate is released by opening the drain at shutdown or service intervals rather than automatically. If you prefer automatic or differential-pressure draining, those are catalogue options in the same size - ask us to quote the alternative code.
