About the AirTAC GC300-08 FRL Unit (GC30008MC1W)
GC30008MC1W is an AirTAC G-series three-unit F.R.L. combination: separate filter, regulator and lubricator built as one 300-size set with PT1/4 ports. The W code fits the fine 5 um filter element for tighter particulate control than the standard 40 um grade, with a manual-drain bowl that is bled by hand on a maintenance schedule. With a manual drain the regulator adjusts over 0.05-0.9 MPa (7-130 psi), and the round external pressure gauge on the MPa (1) scale is included.
This is a genuine AirTAC part. The GC series is offered in 200, 300, 400 and 600 sizes, with PT as the standard thread and G (BSPP) or NPT as catalogue options, automatic or differential-pressure drain alternatives, and a choice of gauge types and scales. The 300-size bowls are polycarbonate (PC). Max inlet pressure is 1.0 MPa (145 psi) and working temperature is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so we confirm sizing and datasheet figures 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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.

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: GF300-08 filter, GR300-08 regulator and GL300-08 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 GC300-08 FRL Unit (GC30008MC1W) Is Used
Analytical instrument air
Point-of-use treatment upstream of laboratory analyzers and sample-handling actuators, where the 5 um element trims fine particulate before it reaches sensitive pilot valves.
Optical assembly benches
Feeding air-driven pick-and-place fixtures and vacuum generator supplies at precision assembly stations that call for cleaner-than-standard plant air.
Process control valve panels
Conditioning positioner and pilot air on process valve manifolds, with the regulator holding a fixed setpoint and the round MPa gauge giving operators a visible line check.
Is the AirTAC GC300-08 FRL Unit (GC30008MC1W) the Right Station?
Size 300 with 1/4 in PT ports is the mid-range G-series step; drop to 200 for compact branches or move to 400/600 for larger mains. Choose this W code when the 5 um element is wanted for finer particulate removal; the standard 40 um grade suits general plant air and holds longer between element attention. Manual drain means scheduled hand bleeding; pick A (automatic) or the blank differential-pressure drain for unattended operation, noting the regulator range then reads 0.15-0.9 MPa (20-130 psi) instead of 0.05-0.9 MPa (7-130 psi). The round MPa gauge is included in this code; square-gauge and psi/bar scale versions exist. PT is standard, with G (BSPP) and NPT orderable to match your piping. Flow is published as curves, not a single rating - ask us to confirm sizing before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" 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 0.05 - 0.9 MPa (7 - 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008MC1W) FAQ
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no single flow number is quoted here. Send us your line pressure and air demand and we will confirm sizing against the datasheet on request.
The W code fits a 5 um element for applications with finer-particle sensitivity, while the standard 40 um grade suits general plant air. Both are catalogue options on this 300-size set, so pick GC30008MC1 for 40 um or GC30008MC1W for 5 um; if you are unsure, tell us the downstream equipment and we will help you decide.
