AirTAC GFR300-10 Filter Regulator (GFR30010ALC1)
The AirTAC AirTAC GFR300-10 Filter Regulator (GFR30010ALC1) 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 PT3/8" 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.

About the AirTAC GFR300-10 Filter Regulator (GFR30010ALC1)
GFR30010ALC1 is an AirTAC GFR-series filter regulator in the low-pressure type: one body filters water and particulate from compressed air and regulates downstream pressure at reduced set points. This 300-size unit has a PT3/8 port, an A-code automatic drain, the standard 40 um element, a mounting bracket included, and a C1-coded external round gauge reading in MPa so the set point is visible at a glance.
This is a genuine AirTAC part in the 200/300/400/600 G-series line, offered in other ports and threads (G and NPT as catalogue options), other drain types, the 5 um element and square-gauge variants. The exact adjustment range of the low-pressure type is confirmed from the datasheet on request, along with flow figures, which AirTAC publishes as curves rather than a single rating.

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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Where the AirTAC GFR300-10 Filter Regulator (GFR30010ALC1) Is Used
Gentle blow-off station
Sets a low, stable blow-off pressure for chip and dust clearing on an electronics assembly bench, with the MPa round gauge making the set point easy to read and verify.
Panel-mounted supply branch
Bracket included, so it mounts straight onto the machine frame and feeds a valve manifold on a packaging line branch that runs at reduced pressure.
Filling line low-pressure section
Regulates the low-pressure section of a liquid filling line, where the automatic drain keeps condensate out of the product-contact valve zone.
Is the AirTAC GFR300-10 Filter Regulator (GFR30010ALC1) the Right Unit?
Pick the L-coded low-pressure type when the process calls for gentle set points rather than full line regulation - and note that its adjustment span differs from the standard type, so we confirm the range from the datasheet before you order. The C1 option puts an external round gauge with an MPa scale on the unit; an embedded square gauge is the alternative. Automatic drain handles condensate unattended, and the bracket is included for panel or frame mounting.
Flow is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering. The thread is standard PT; G (BSPP) and NPT are order options.
Quick checklist
- ✓ Body size for your peak flow (PT3/8" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Oil needed downstream? Use GFC instead
Installation & Maintenance Notes
- check Mount vertically, bowl down, following the airflow arrow.
- check One body does the filtering and the regulating — no separate regulator needed.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.15 - 0.9 MPa (20 - 130 psi).
- check Drain condensate before the bowl fills.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
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 GFR300-10 Filter Regulator (GFR30010ALC1) FAQ
No single rated flow number exists to quote: AirTAC publishes flow for the G series as curves. Send your working pressure and air demand and we will confirm the sizing and the datasheet figures on request before you order.
The L code selects the low-pressure regulator type, intended for reduced set points rather than full line pressure regulation, and it carries a different adjustment span from the standard type. This unit also includes a mounting bracket and an external round MPa gauge, which the square-gauge versions do not have. We confirm the exact adjustment range from the datasheet on request.
