The AirTAC GR40010F2 AirTAC Air Pressure Regulator 3/8 in PT 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 GR40010F2 is an AirTAC GR-series air pressure regulator: it does one job, holding your downstream pressure steady at the value you set, regardless of swings in supply pressure or changes in air demand. This is the 400 size with a PT3/8 (3/8 in) port, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the F2 code means an embedded square gauge with a psi scale is fitted so you can read and dial in the setting directly at the unit. Maximum inlet pressure is 1.0 MPa (145 psi), and the GR series handles a working temperature of -20 to 70 C, wider than the rest of the G family.
This is a genuine AirTAC part. The GR line spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, an optional low-pressure type limited to 0.4 MPa, and a choice of gauge scales. Because AirTAC publishes flow performance as curves rather than a single rated figure, we confirm the datasheet and flow data for your exact model 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 machine-tool clamping circuit, the GR40010F2 sets and holds the clamp pressure at the value the fixture was designed for, so workpieces are gripped consistently across every cycle instead of at whatever the shop supply happens to deliver.
Feeding cylinders on a carton-forming or case-packing conveyor, this regulator lets the line technician set one stable downstream pressure for the sealing and pusher actuators, protecting them from supply-line surges and keeping motion repeatable.
At the point of use in an assembly cell, the GR40010F2 takes the 3/8 in main drop and reduces it to the pressure the cell's tools and grippers need, with the fitted psi gauge giving operators a visible, adjustable setpoint at the station.
Start with the port and size: the 400 size steps up in flow capacity and port size from the 300, so pick 400 when your line runs larger piping or higher demand - match the 3/8 in PT port to your existing pipework, or order the G (BSPP) or NPT variant if your installation uses those threads. Set your gauge scale to suit the crew: this unit carries the square psi gauge (F2), while MPa and bar scales and an external round gauge are available in the series. If your setpoint never exceeds 0.4 MPa, the low-pressure L type is worth considering; otherwise this standard type covers 0.05-0.9 MPa. A mounting bracket is included, and the GR400 is also panel-mountable. One honest note on sizing: AirTAC publishes regulator flow as curves, not a single rated number, so ask us to confirm the flow data against your application before you order.
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 performance as curves rather than a single rated figure, so there is no one flow number we can quote for this model. Tell us your supply pressure, set pressure and expected air demand, and we will confirm the flow data from the datasheet for the GR400 size before you order.
The F2 code on GR40010F2 means an embedded square gauge with a psi scale is fitted as standard. If your team works in metric units, the GR series is also available with MPa or bar gauge scales, and an external round gauge is an option - specify the scale you want when ordering, alongside G (BSPP) or NPT thread variants if PT does not suit your pipework.
