The AirTAC GFR300C15C2W AirTAC Filter Regulator PT1/2, 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 GFR300C15C2W is an AirTAC GFR300 filter regulator: a 1/2 in (PT1/2) unit that removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries the optional 5 um filter element (the W grade, finer than the 40 um standard), a differential-pressure drain, a round pressure gauge reading in psi, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The 300 size uses a polycarbonate bowl, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads as order options alongside the PT standard. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet details 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.

Cleaning and regulating the air that feeds clamps, tool changers and blow-off nozzles on a CNC machining cell, where compressor condensate and shop-air grit reach the machine's point of use.
Steadying air to sorter diverters, case sealers and carton-closing cylinders on a packaging line, so actuation stays consistent while upstream demand from other stations fluctuates.
Filtering and regulating supply to weld-gun clamps and fixture cylinders in a robotic welding cell, keeping contaminated shop air away from the valve stack at each gun.
Size and port step up with flow demand: the 200, 300, 400 and 600 bodies take 1/8 in through 1 in ports, so match the port to your line and let the published flow curves - not a single rating - settle the size; we will confirm sizing against your application on request. Drain choice is differential-pressure (the default, fitted here), automatic (A) or manual (M), and filtration is 40 um standard or 5 um with the W code, as on this unit. Gauges can be omitted (N) or ordered with MPa, psi or bar scales, and the thread is PT as standard with G (BSPP) and NPT available to order. A mounting bracket is included unless the J (no bracket) code is specified.
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 GFR300 as curves, not as a single rated number, so there is no one figure we can quote honestly. Tell us your application and we will confirm the flow and full datasheet figures for this exact model on request.
The W code at the end of GFR300C15C2W selects the optional 5 um filter grade, finer than the 40 um standard, for points of use that need cleaner air. Drain type (differential-pressure here, automatic A or manual M), gauge scale and G or NPT threads are also order-time choices across the GFR family.
