About the AirTAC GC300-15 FRL Unit (GC30015ALF1K)
GC30015ALF1K is a genuine AirTAC G-series three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator built as one 300-size station for compressed air only, with a reverse (check) valve fitted as indicated by the K suffix. The 1/2 in PT port suits a main drop feeding several downstream circuits. The automatic drain opens the filter bowl as condensate collects, the standard 40 um element handles general-purpose particulate removal, and the low-pressure (L) regulator type is set up for circuits running below standard line pressure. An embedded square gauge on an MPa scale shows the regulated downstream pressure, and the lubricator meters oil mist into the air stream.
The G series spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, available as single units, two-unit sets or three-unit combinations in PT, G (BSPP) or NPT threads. On this 300 size the bowls are PC (polycarbonate), operating temperature is -5 to 70 C (non-freezing) and maximum working pressure is 1.0 MPa (145 psi). Flow is published as curves rather than a single rated figure, so ask us to confirm datasheet and sizing figures for your application on request.

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. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
Model Code: AirTAC GC300-15 FRL Unit (GC30015ALF1K)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 15 | Port size PT1/2". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-15 filter, GR300-15 regulator and GL300-15 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the AirTAC GC300-15 FRL Unit (GC30015ALF1K) Is Used
Robotic weld cell air feed
Conditioning the compressed air feeding gripper and clamp actuators in a robotic welding cell, where the fitted check valve is part of the specified circuit arrangement.
Palletiser gripper circuit
Supplying filtered, regulated and lubricated air to vacuum and grip actuators on an end-of-line palletiser fed from a 1/2 in drop, with automatic condensate draining.
Automotive assembly tool ring
Feeding nutrunners and pneumatic screwdrivers along an automotive trim line, combining filtration, low-pressure regulation and oil-mist lubrication at the tool ring main.
Is the AirTAC GC300-15 FRL Unit (GC30015ALF1K) the Right Station?
This configuration gives you a 300-size F.R.L. with a 1/2 in PT port, automatic drain, standard 40 um element, embedded square MPa-scale gauge and a fitted reverse (check) valve (K). Step to a 200 or 400/600 size if your flow demands it, or drop the K suffix if you do not need the check valve. The drain can be ordered as manual (M) or differential-pressure (blank) instead of automatic (A), the element as 5 um (W), and the gauge as an external round type with psi or bar scale. The thread can be ordered as G (BSPP) or NPT instead of the standard PT. Because this is the L (low-pressure) type, confirm the exact adjustment range with us before ordering. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before you order.
Quick checklist
- ✓ Body size for your peak flow (PT1/2" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- 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 the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC GC300-15 FRL Unit (GC30015ALF1K) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so we do not state a number here. Share your inlet pressure and consumption profile and we will confirm the curve and datasheet figures for this exact model on request.
K means a reverse (check) valve is fitted on the unit. The same set without the K suffix (GC30015ALF1) is identical otherwise. If your circuit calls for the check valve, order the K version; we can confirm the circuit detail with you on request.
