SMC AW40-04B-2-D | AW40 Filter Regulator 1/2" Rc, Metal Bowl, Bracket, No Drain/P.Gauge
SMC AW40-04B-2-D modular filter regulator — body size 40, 1/2" Rc port, metal bowl, with mounting bracket. No auto drain, no pressure gauge. 5 µm filtration, 0.05–0.85 MPa set range.
Product Overview
The SMC AW40-04B-2-D is a modular combination filter regulator (FRL) from the AW series, integrating particulate filtration and pressure regulation in a single compact unit. It features Body Size 40, Rc 1/2" (04) threaded ports, a metal bowl (Code 2), and is supplied with mounting bracket (B) but without pressure gauge, without automatic drain, and without pressure switch. The standard filter element provides 5 µm rating and the regulator is factory-set for 0.05–0.85 MPa (7–123 psi) output range. It is designed for panel or frame mounting in pneumatic main-air lines upstream of actuators or downstream of the main compressor receiver.

Key Features
-
Space-Saving Combo Design: One unit replaces separate filter + regulator — reduces piping, weight, and footprint on the air header.
-
Metal Bowl (Code 2): Suitable where polycarbonate bowls are prohibited (high temperature, aggressive cleaning agents, mechanical impact risk).
-
Bracket Included (Option B): Pre-assembled L-bracket allows direct panel or frame mounting — no extra hardware to source.
-
Modular Expandability: Can be coupled with SMC AW / AL / AM series units (lubricator, secondary filter, shut-off valve) using union connectors.
-
Easy Element Replacement: Filter cartridge unscrews with bowl — no tools required for routine maintenance.
Typical Applications
-
Main Air Line Conditioning: Installed at machine entry point to clean and regulate shop air before distribution to valves/cylinders.
-
Packaging / Assembly Machinery: Where consistent regulated pressure and particle-free air are critical to cycle repeatability.
-
Food / Pharma Auxiliary Lines (with metal bowl): Where PC bowls are excluded by plant hygiene/WIP policy — verify chemical compatibility of metal bowl coating.
-
Retrofit / Panel Build: Drop-in replacement for older SMC AR + AF combinations or other ISO-compliant FRL brands with same port spacing.
Code Breakdown: AW40 = Body Size 40 | -04 = Rc 1/2" port | -B = With mounting bracket | -2 = Metal bowl | -D = No auto drain / no gauge (manual drain plug). For polycarbonate bowl with guard use AW40-04BG-D; for auto drain add -D after gauge code (e.g. AW40-04BDG-D).
