The AirTAC GFR30010F2TK AirTAC Filter Regulator, NPT3/8, psi Gauge 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 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 GFR30010F2TK is a size-300 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, the standard 40 um filter element, a differential-pressure drain that bleeds collected condensate automatically when the pressure differential across the element rises, an embedded square gauge scaled in psi, a fitted reverse/check valve that holds downstream pressure when the supply drops, and a mounting bracket included. Maximum inlet pressure is 1.0 MPa (145 psi), the standard regulation range is 0.15-0.9 MPa (20-130 psi), and the operating temperature is -5 to 70 C (non-freezing). The polycarbonate bowl suits general-purpose installations; only the size-600 units use an aluminium alloy bowl.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, filter grades of 40 um (standard) or 5 um (code W), differential-pressure, automatic or manual drains, square or external round gauges scaled in MPa, psi or bar, G (BSPP) or NPT thread options, and an optional low-pressure regulator type. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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 conditioning ahead of a pneumatic press or clamping station: the 40 um element strips water and pipe scale, the regulator holds a steady set pressure for consistent clamping force, and the check valve keeps the circuit pressurised during brief supply dips.
Feeding diverters, stops and gate cylinders on a packaging or material-handling conveyor line, where the square psi gauge lets operators verify set pressure at a glance and the differential-pressure drain keeps condensate out of the valve manifold.
A dedicated filtered-and-regulated drop feeding air-operated control components and pilot valves on a production machine, with the mounting bracket securing the unit to the machine frame and the 3/8 in NPT port matching standard plant drop piping.
Choose the size and port step against the air demand of the circuit: this unit is size 300 with a 3/8 in NPT port; larger sizes carry larger ports and higher flow capacity. Drain options are differential-pressure (this unit, self-acting), automatic, or manual; pick manual where you want controlled inspection, automatic where condensate loads are heavy. Filter grade is 40 um standard or 5 um (W) for finer protection. Gauge choices are the embedded square gauge (this unit, psi scale) or an external round gauge in MPa, psi or bar scales. Thread is NPT here; G (BSPP) is an order option, and PT is the catalogue standard. A bracket is included, and the K code adds a reverse/check valve to hold downstream pressure. 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. 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 capacity curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and required flow, and we will confirm the sizing against the datasheet curves on request before you order.
The differential-pressure drain (the default, fitted on this model) releases collected condensate automatically when the pressure drop across the 40 um element rises, so no operator action is needed in normal service. If you prefer a drain that opens only when operated, order the automatic (A) or manual (M) drain variants of the same size 300 filter regulator.
