The AirTAC GFR30010AJF1TK AirTAC Filter Regulator 3/8in NPT 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 PT3/8" ports, a automatic 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 GFR30010AJF1TK is a GFR300 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/8 in NPT port, an automatic drain that ejects collected condensate without manual attention, a 40 um standard filter element, an embedded square pressure gauge scaled in MPa, and a built-in reverse/check valve that holds downstream pressure if the upstream supply drops. The polycarbonate bowl suits this 300 size, and no mounting bracket is fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR filter-regulator line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and options include automatic, manual or differential-pressure drains, a 5 um (code W) element, square or round gauges with MPa, psi or bar scales, a reverse/check valve, and G (BSPP), NPT or PT threads. Flow for this unit is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Point-of-use conditioning for a CNC machining centre: the 40 um element strips water and chips of particulate before the shop air reaches solenoid valves and tool-change cylinders, while the regulator holds a steady set pressure and the check valve keeps the circuit charged if the main supply dips.
Feeding pneumatic clamp and divert cylinders on a carton packaging line: the filter-regulator sits at the line drop, the automatic drain keeps condensate out of the valves without operator rounds, and the MPa square gauge lets the line technician verify set pressure at a glance.
Conditioning air tapped from a textile plant's humid, heavily cycled ring main: the GFR300 removes moisture and lint-laden particulate before air reaches loom and winder actuators, and the built-in check valve protects the machine circuit from upstream pressure loss during compressor changeover.
Size the GFR series by port and expected flow: this unit is size 300 with a 3/8 in NPT port; larger sizes (400, 600) carry bigger ports and more flow capacity, and flow is published as curves rather than one rated number, so ask us to confirm sizing against your application before ordering. Choose the drain to suit the installation: automatic (this unit) suits unattended duty, manual suits periodic checks, and differential-pressure drain is the catalogue default. The 40 um element is standard; specify the 5 um W grade where finer particulate removal is needed. The embedded square gauge here reads in MPa; round external gauges and psi or bar scales are available. Thread: PT is the AirTAC standard, with G (BSPP) and NPT (this unit) as orderable options. Brackets are optional; this configuration ships without one.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The reflux valve permits reverse flow 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 number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your application and we will confirm the flow curve and correct sizing from the datasheet on request before you order.
The A in the code sets the automatic drain: collected condensate is ejected from the polycarbonate bowl without manual attention, which suits unattended installations. The K sets a built-in reverse/check valve, which holds downstream pressure if the upstream supply is lost. If you would rather drain manually, or do not need the check valve, the corresponding GFR300 variants are available - ask us for the exact codes.
