The AirTAC GAFR Filter & Regulators GAFR400 is a genuine two-in-one filter & regulator — a diversion-type water/particulate filter and a balanced pressure regulator built into ONE body. It has See datasheet ports, a 40 µm filter element and regulates 0.15 - 0.9 MPa (20 - 130 psi). It has no lubricator, so it adds no oil to the airflow.
The AirTAC GAFR400 puts an air filter and a pressure regulator into one 3/8in body, so a single unit does two jobs and your air preparation takes one fewer joint to seal. Incoming air is spun by a diversion structure that drops liquid water and solid grain into the 100 cc drain bowl, then the balanced regulator holds any setting from 0.15 to 0.9 MPa (20-130 psi). The 40 um standard element suits general machine air, and there is no lubricator anywhere in this unit.
At 880 g this is a mid-size component that belongs on its included mounting bracket or a panel, not hanging on the tubing. The circular gauge ships fitted and reads MPa and psi because the PT thread code sets that scale, and the pressed-in knob keeps your setting locked as vibration shakes the line. Rated from -5 to 70 C, the unit must never be allowed to freeze.

Specifications follow the official AirTAC GAFR catalogue (pages 235-236). Air must not freeze in the unit. The fitted circular gauge reads in MPa / psi, set by the PT thread code. This unit filters and regulates only; it does not add lubrication.

The filter and the regulator are ONE body here — there is no separate GAF filter or GAR regulator part to assemble. Need lubrication downstream too? Add a lubricator by ordering the matching GAFC400- F.R.L. combination instead.
Figures are the end of the flow curve plotted in the AirTAC catalogue at 0.7 MPa inlet pressure — a sizing envelope for comparing bodies, not a rated flow. Read the catalogue curve for a real duty point. Outlet pressure falls as flow rises, so size a body with headroom above your peak demand.

Clamping fixtures on a milling or turning center draw bursts of air through 3/8in drops. This unit filters chips' enemy, condensed water, out of the supply and holds a steady clamp pressure as the plant header wanders.
Sealing jaws and vacuum cups on packaging machines run best on clean, stable air. The 100 cc drain bowl captures the moisture a shift produces, and operators vent it at the manual drain during changeovers.
A 3/8in drop in a maintenance bay feeds impact tools, test rigs and blow-off guns. One GAFR400 on the wall bracket conditions that whole drop, and the fitted gauge lets technicians read pressure at a glance.
Port code 10 makes this the 3/8in member of the GAFR400 family; a GAFR300 on the same port is one size down and a GAFR500 on 3/4in is one size up. The blank bowl position means clear PC here, while C orders metal and N orders nylon on this body, and only the GAFR600 is restricted to metal. With no option letters in the SKU, you get the standard 0.15-0.9 MPa type, both a semi-auto and a manual drain, the mounting bracket, a fitted gauge on a 1/4in connection with MPa and psi scales (PT thread), and the 40 um element. If downstream actuators need oil mist, order the matching GAFC400 combination instead, since a GAFR never adds lubrication; use W for a 5 um element or K for a reverse-flow valve when the application calls for them.
Sizing check: the flow curve of this body is plotted to 7000 L/min at 0.7 MPa inlet, 2x the 3500 L/min envelope of a GAFR300, so step up from the smaller body only when your air demand actually doubles.
Quick checklist
This is a filter and regulator only — it delivers filtered, pressure-set air with no added oil. If a downstream tool needs lubrication, add a separate lubricator or order the GAFC400- combination; do not expect an oil mist from this unit.
It is a filter and regulator in one 3/8in body. Standard type covers 0.15-0.9 MPa (20-130 psi) of regulated outlet, with a maximum pressure of 1.0 MPa (145 psi) and a proof pressure of 1.5 MPa (215 psi). Temperature range is -5 to 70 C and the unit must not freeze. The condensate bowl holds 100 cc, the unit weighs 880 g, the element grade is 40 um, and the gauge connection is 1/4in.
This model, with no drain letter in the code, ships with both a semi-auto drain and a manual drain fitted to the same bowl. If the line runs unattended or carries heavy condensate, order GAFR40010ASA instead; the A code swaps in an automatic drain on the identical 3/8in body.
