The AirTAC GR40010F2T AirTAC Air Pressure Regulator NPT3/8 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/8" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR40010F2T is an AirTAC GR400 series air pressure regulator, a genuine AirTAC part built for one job: holding a steady, adjustable downstream pressure from a compressed-air supply. This 400-size unit is fitted with a 3/8 in NPT port and comes with the embedded square pressure gauge scaled in psi, so the setpoint can be read and adjusted directly at the unit. It is the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and it accepts a maximum inlet (working) pressure of 1.0 MPa (145 psi). Operating temperature is -20 to 70 C, a wider window than the rest of the G family, which helps in colder shops and unheated plant areas.
GR400 is one of four sizes in the range (200/300/400/600), each stepping up in port size and flow capacity. Across the series you can order NPT or G threads instead of the PT standard, choose a psi, MPa or bar gauge scale, add a reverse/check valve, or specify the low-pressure type. Because AirTAC publishes regulator flow as curves rather than a single rated figure, we confirm the exact flow and datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. 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, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

On a fabrication cell's pneumatic clamping press, this regulator sits after the main shut-off valve and holds a fixed clamping pressure so workpieces are gripped consistently across every cycle, with the psi gauge letting the setter verify the setpoint at a glance.
On a carton packaging line, the GR40010F2T feeds the divertor and sealing cylinders at a reduced, stable pressure so cartons are sealed without crushing, while the wider -20 to 70 C rating suits dock-side lines exposed to cold air.
On a robotic pick-and-place cell, this regulator on the gripper air manifold keeps the supply pressure to the gripper jaws constant regardless of swings in the plant header, protecting delicate parts from over-gripping.
Start with the port and size step: this unit is 400 size with a 3/8 in NPT port, one step up from the 300 series, so size up if your line's flow demand sits above what a smaller regulator can pass - we will check the published flow curves against your application before you order. The gauge here is the embedded square type scaled in psi; MPa and bar scales are available if your team works in metric. Thread is NPT as coded, with PT (the standard) and G (BSPP) as orderable options - this is a specification choice, not a delivery matter. A mounting bracket is included, and the GR400 is also panel-mountable if you prefer a fixed manifold layout. If your circuit needs the regulator to hold downstream pressure during upstream decay, ask about the K option, which adds a reverse/check valve.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves rather than a single rated number, so there is no one rated-flow figure we can honestly quote. Send us your line pressure, set pressure and expected air demand, and we will confirm the sizing from the GR400 datasheet curves on request before you order.
The T at the end of GR40010F2T codes the 3/8 in port as NPT thread; PT is the series standard and G (BSPP) is also an orderable option, so you can match your existing pipework. The fitted square gauge here reads in psi (the 2 scale code); MPa and bar scales are available, and an external round gauge can be specified instead of the embedded square one.
