AventicsFilter Pressure Regulator, G1/4 BSPP, 5 Micron, 1000 l/min, 0.5–8 bar, Polycarbonate Bowl, No Gauge

Product Description

What this part is

An AVENTICS Series AS1-FRE filter pressure regulator, a filter and a regulator built into a single modular body, so one unit removes water and particulate and then holds a stable downstream set pressure. It is the middle element of a modular G1/4 air preparation chain, the AS1 answer to a conventional FRL, and clamps to the neighbouring AS1 modules rather than screwing into pipe on both ends.

Decoding the order code

Full factory code: AS1-FRE-G014-GAN-080-PNB-AO-05.00. AS1: AVENTICS Series AS1 modular air preparation. FRE: filter pressure regulator, filter and regulator combined. G014: G 1/4 parallel (BSPP) air connection rather than NPT. GAN: no pressure gauge fitted; the GAI variant carries an integrated gauge. 080: regulation range to 8 bar. PNB: polycarbonate reservoir bowl. AO: automatic condensate drain, open when unpressurised. 05.00: 5 µm filter element.

What these specs mean in practice

There is no gauge on this build. Set pressure is read at a separately fitted gauge, either in the downstream line or in the AS1 gauge port.

A 5 µm element is general-purpose protection for valves, cylinders and air tools rather than instrument-grade air. The series carries separate microfilter and active-carbon modules at 0.3 µm and 0.01 µm, and this unit does not replace them.

The automatic drain dumps collected condensate on its own and sits open when the unit is unpressurised, so a machine shut down overnight self-empties instead of filling the bowl. A polycarbonate bowl keeps the level visible and is attacked by solvents and by some compressor oils.

Published specifications

Type: filter pressure regulator, Series AS1-FRE. Compressed air connection: G 1/4 (BSPP). Nominal flow: 1000 l/min. Working pressure: 1.5 bar minimum to 12 bar maximum. Regulation range: to 8 bar. Filter porosity: 5 µm. Reservoir: polycarbonate. Condensate drain: automatic, open without pressure. Pressure gauge: not fitted (GAN). Ambient temperature: −10 °C to +50 °C. Media: compressed air. Mounting: modular AS1 chain.

Quantity and configuration

One filter regulator module, removed unused from an R480342567 air preparation unit. No pressure gauge, no mounting bracket and no connection plates are included.

Mounting data

This build flows left to right; the R→L build of the same unit is R412014731. Clearance under the bowl is required for drain access and element changes.

Interchange guidance

R412014731 is the same unit built right-to-left. R412014645, R412014646 and R412014648 are the GAI (gauge fitted) and alternate-bowl builds in the same envelope, related versions rather than equivalents of this exact code. R412014658 is the 5 µm, 12 bar AS1 filter regulator with a semi-automatic drain.
