The AirTAC GFR40015JF2 AirTAC Filter Regulator PT1/2, 40 um, 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 PT1/2" 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 GFR40015JF2 is a size-400 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is threaded PT1/2 (1/2 in, PT standard), carries the standard 40 um filter element, drains condensate by differential pressure, and is fitted with an embedded square gauge scaled in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and no mounting bracket is included. Max inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing. The polycarbonate bowl suits sizes 200-400 (only size 600 uses an aluminium alloy bowl).
This is a genuine AirTAC part from the GFR400 series. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic or manual drain alternatives, G or NPT thread options, and gauge scale choices. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing 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.

Feeding filtered, regulated air to tool-clamp and tool-change cylinders on a CNC machining centre, where the 1/2 in port matches the machine's main air drop and the psi gauge lets setters read set pressure directly.
Conditioning the air that drives carton-sealing and case-erecting cylinders on a packaging line, with the 40 um element catching pipe scale and the differential-pressure drain clearing accumulated water during runs.
Supplying regulated air to pneumatic clamps and light press fixtures in a fabrication cell, where the square psi gauge gives operators a visible setpoint and the single filter-regulator body saves panel space.
Start with the size and port: the 400 frame with its 1/2 in PT port sits in the upper-middle of the GFR range (200/300/400/600), so match it to your line's pipe size and expected demand - we can confirm the flow curve against your application. Choose the drain: this unit uses the differential-pressure drain (default); automatic (A) or manual (M) drains are available on other codes. The 40 um element is the standard grade; specify a W code if you need 5 um. The square gauge here is scaled in psi; MPa or bar scales and an external round gauge are alternatives. Thread is PT as standard - order G (BSPP) or NPT variants if your piping needs them. This code has no bracket (J); bracketed versions exist. Flow is published as curves, not a single rating, so ask us to confirm sizing before you order.
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 GFR400 series as curves, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow curve and sizing from the datasheet on request before you order.
This unit's differential-pressure drain (the blank code position) bleeds condensate from the polycarbonate bowl automatically as the pressure differential across the filter builds. If you prefer, other GFR400 codes offer an automatic drain (code A) or a manual drain (code M); the manual-drain variant also widens the regulator adjustment range to 0.05-0.9 MPa (7-130 psi).
