The AirTAC GFR300C15MJC2WGK AirTAC Filter Regulator, G1/2, 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 GFR300C15MJC2WGK is a size-300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a G1/2 (BSPP) port, a 5 um filter element (the finer of the two catalogue grades), a manual drain for hand-bleeding the metal bowl, a round pressure gauge reading in psi, and a built-in reverse/check valve. The standard-type regulator covers an adjustment range of 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi) and a working temperature of -5 to 70 C (non-freezing). It is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, square or round gauges in MPa, psi or bar scales, and an optional check valve. Flow is 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 0.15 - 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 conditioning for a machining centre's pneumatic circuit: the 5 um element strips water and fine particulate before the machine's solenoid valves and tool-clamp actuators, while the regulator holds the clamp circuit at its set pressure and the round psi gauge lets a technician read it directly.
Mounted at the air drop feeding a packaging line's cylinders and vacuum grippers. The regulator keeps actuator speed consistent at the set pressure, the check valve holds downstream settings if upstream supply dips, and the manual drain lets an operator bleed accumulated condensate during shift checks.
Regulating and filtering the air that actuates weld-gun clamps and positioners in a robotic cell. The 5 um grade protects the cell's control valves from contamination, the psi gauge supports routine pressure verification, and the manual drain suits cells serviced on a fixed maintenance schedule.
Size 300 with a 1/2" port sits in the middle of the GFR range; step up to size 400 or 600, or down to 200, according to the flow your line needs - we will check the published flow curves against your demand on request. This unit's 5 um element suits air that feeds sensitive valves, cylinders or instruments; the 40 um grade is the standard choice for general plant air. The manual drain (code M) means an operator bleeds the bowl by hand, and it also widens the regulation range to 0.05-0.9 MPa (7-130 psi) versus 0.15-0.9 MPa with automatic or differential-pressure drains. The fitted round gauge reads in psi; square embedded gauges and other scales are catalogue options. The thread here is G (BSPP); PT is the standard thread and G or NPT are specification options to order. No bracket is included with the J code, though brackets are an available option, and the K code adds a check valve to hold downstream settings.
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 one number. Send us your application details - required flow, working pressure and downstream equipment - and we will confirm the sizing from the datasheet curves on request before you order.
The M code fits a manual drain: an operator opens it by hand to release collected condensate from the metal bowl, which suits installations checked on a regular schedule. It also gives this standard-type regulator the wider 0.05-0.9 MPa (7-130 psi) adjustment range; the automatic and differential-pressure drain options carry a 0.15-0.9 MPa (20-130 psi) range. Automatic and manual drains are catalogue alternatives if your duty suits them better.
