The AirTAC AirTAC GFC300-08 Combination Unit (GFC30008LF1) is a genuine G-series two-unit air-preparation set: a filter regulator that filters and regulates in one body, coupled to a lubricator. Two bodies do the work of three, with PT1/4" ports, a 40 µm element, a differential-pressure drain and regulation over 0.15 - 0.9 MPa (20 - 130 psi).
GFC30008LF1 is a two-piece AirTAC G-series air-treatment set: a filter-regulator paired with a lubricator, giving the downstream circuit filtered, regulated and oil-mist-lubricated compressed air through PT1/4 (1/4 inch) ports. The regulator is the low-pressure type for circuits set below standard line pressure, the 40 um element with differential-pressure drain handles water and particulate removal, and the set is fitted with a square pressure gauge scaled in MPa.
This is a genuine AirTAC part. The G series spans 200, 300, 400 and 600 sizes with 1/8 to 1 inch ports; options across the family include automatic or manual drains, a 5 um filter element, external round gauges, psi or bar scales, and G (BSPP) or NPT threads. Maximum working pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so we confirm flow 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The set has no separate bracket code — the two 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 set. Constituent units, orderable separately as spares: GFR300-08 filter regulator and GL300-08 lubricator.
A GFC is two units because filtering and regulating share one body. A GC is three separate units — filter, regulator and lubricator. Both filter, regulate and lubricate; the GFC is the shorter assembly, the GC keeps the filter and regulator serviceable as separate bodies.

Feeding screwdrivers and small impact tools at assembly benches that run at reduced pressure, with the oil mist extending tool motor life and the 40 um filter stopping scale from entering the collet mechanism.
Running thread-guiding and cleaning air jets on a weaving or spinning frame set below main line pressure, keeping the jets supplied with filtered, regulated and lubricated air.
Supplying pilot air to actuated ball and butterfly valves on a process skid running at low pressure, with lubrication protecting the positioner and actuator internals.
Both units are size 300 with PT1/4 (1/4 inch) ports; step to 200, 400 or 600 for a different port size. The filter-regulator bowl uses the differential-pressure drain as its default, with automatic (A) and manual (M) versions orderable, and the 300-size bowl is polycarbonate. The 40 um element is standard - the W suffix gives 5 um. This code's F position specifies the square gauge on the MPa scale; round-gauge versions and psi or bar scales are available in the family. The regulator is the low-pressure type, so confirm its adjustment range against your setpoint with us. PT is the standard thread, with G (BSPP) and NPT available to order. Flow is published as curves rather than a single rating, so ask us to confirm sizing against your application before ordering.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream, so if any branch must stay oil-free, take that branch off before the lubricator or use a GFR300-08 filter regulator on its own.
Yes. AirTAC publishes flow for this size as performance curves rather than a single rated figure, which is why no flow number appears here. Send your operating pressure and air demand and we will confirm the figures from the datasheet and check the sizing against your application.
They are the gauge options: F specifies the square gauge and C the external round gauge, each with a trailing scale digit (1 = MPa, 2 = psi, 3 = bar). This model, GFC30008LF1, carries the square gauge on the MPa scale. Drain type and the 5 um W element are separate choices we can walk through on request.
