The AirTAC GFR600-25 AirTAC Filter Regulator 1 in PT, Auto Drain 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" ports, a automatic 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in one body. This 600-size unit is threaded PT1 (1 in) and carries an automatic drain, so collected condensate is expelled without manual attention. Filtration is the standard 40 um grade, the bowl on size 600 is aluminium alloy, and the fitted round gauge reads in psi so outlet pressure can be set and checked at a glance. The built-in reverse (check) valve holds the downstream circuit if upstream supply is interrupted, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR line runs from size 200 to 600 with port sizes from 1/8 in to 1 in, and options include manual or differential-pressure drains, a 5 um element, G or NPT threads, gauge scale choices and low-pressure variants. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet figures 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.

At the 1 in header take-off feeding a stamping press cell, the GFR600-25 strips water and scale from the main supply and holds a steady regulated pressure to the press air-over-oil and clamping circuits, with the check valve holding the circuit during supply dips.
On a bottling hall conveyor section driven by pneumatic diverters and stop-gates, this unit filters the plant supply to 40 um and regulates it to the pressure the gate cylinders were set up for, while the automatic drain copes with condensate from long distribution runs.
Ahead of a 1 in solenoid-valve manifold controlling a bulk-material gate or damper actuator, the GFR600-25 removes moisture and particles that would score valve seats and holds supply pressure stable so actuator stroke times stay repeatable.
Start with the port step: this unit is 1 in PT, the largest in the GFR range, so step down to a smaller size if your line runs at lower flow. Choose the drain to match access: automatic (this unit) suits unmanned or hard-to-reach installations, manual suits supervised daily checks, and differential-pressure drains only when the element loads up. Filter grade is 40 um standard; specify W for 5 um where finer pre-filtration is needed. Gauge scale is selectable (MPa, psi or bar) and this unit ships with a round psi gauge. PT is the standard thread; G (BSPP) and NPT are order options. A bracket is included; J variants omit it.
Because rated flow is published only as curves, not a single number, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs and we will confirm sizing against the datasheet curves on request before you order.
The A in the code means the bowl drains condensate automatically, which suits installations that are not checked daily. Manual-drain and differential-pressure-drain variants are available in the same series if you prefer supervised draining; regulation range depends on drain type, so confirm the variant with us when ordering.
