AirTAC GC400-15 FRL Unit (GC40015C2)
The AirTAC AirTAC GC400-15 FRL Unit (GC40015C2) is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT1/2" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).

About the AirTAC GC400-15 FRL Unit (GC40015C2)
The GC40015C2 is a three-piece F.R.L. combination from AirTAC's G series: a separate air filter, pressure regulator and lubricator that together clean, regulate and oil-mist-lubricate the compressed air feeding your equipment. This configuration uses 1/2 in. PT ports in the size 400 body, a differential-pressure drain on the filter bowl, the standard 40 um filter element, and a round external pressure gauge with a psi scale for US-style readouts. Maximum inlet pressure is 1.0 MPa (145 psi) and the regulator adjusts from 0.15-0.9 MPa (20-130 psi) with this drain type; operating temperature is -5 to 70 C (non-freezing). The filter and lubricator bowls are PC (polycarbonate) at size 400.
This is a genuine AirTAC part. The G series is offered in sizes 200, 300, 400 and 600, with automatic, manual or differential-pressure drains, 40 um or 5 um filtration, square or round gauges in MPa, psi or bar scales, and G (BSPP) or NPT threads as catalogue options. Flow for the series is published as curves rather than a single rating, so ask us and we will confirm the datasheet and sizing 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 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: GF400-15 filter, GR400-15 regulator and GL400-15 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 GC400-15 FRL Unit (GC40015C2) Is Used
Packaging line fill-and-seal
Prepares air for the fill heads and sealing jaws on a vertical form-fill-seal packaging machine, keeping water and 40 um particulate out of the seal cylinders while feeding them a metered oil mist.
Lab automation actuators
Conditions supply to the pneumatic actuators on laboratory sampling and dispensing equipment, where the psi-scale gauge matches US instrument readouts.
Bottling line rail adjusters
Regulates and lubricates air to the bottle-guide rail adjusters and lift cylinders on a beverage bottling conveyor, holding steady pressure through changeovers.
Is the AirTAC GC400-15 FRL Unit (GC40015C2) the Right Station?
Size 400 with PT1/2 ports suits lines built around 1/2 in. pipework and higher air demand; step to 200/300 for lighter duty or to 600 for the largest ports and flow capacity. The standard 40 um element is the usual choice for general plant air, with the 5 um W grade available when finer filtration is needed. The psi-scale round gauge reads the regulated outlet in familiar US units. The differential-pressure drain clears the bowl automatically as the pressure differential builds. PT thread is the standard on this model; G (BSPP) and NPT are options to order. Rated flow is published as curves, not a single figure, so share your flow demand and we will confirm sizing against the datasheet 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC GC400-15 FRL Unit (GC40015C2) FAQ
AirTAC publishes G-series flow as curves rather than a single rated number, so we do not state a figure here. Give us your working pressure and air consumption and we will confirm the sizing from the datasheet on request.
Yes. The C2 code means a round external gauge with a psi scale; MPa and bar scales are catalogue alternatives. The differential-pressure drain can be swapped for automatic (A) or manual (M), and G (BSPP) or NPT threads can be ordered in place of the standard PT.
