SMC AFD40-D Compressed Air Filters

Also known as coalescing filters, these filter elements fit in SMC modular compressed air filters to remove oil and particles. Check the manufacturer series on your filter to ensure compatibility.

Elements that remove particles down to 0.3 microns are less likely to clog than those that filter to 0.01 microns. Use them for general purpose compressed air, or as a prefilter to protect higher purity filters from clogs.

Elements that remove particles down to 0.01 microns remove even the smallest contaminants from your compressed air. Use them for applications where air purity is critical, such as food processing, electronic manufacturing, or pharmaceutical production.

SMC Modular Compressed Air Filters for Oil Removal

Remove oil from your compressed air line to extend the life of air-powered tools and equipment. These filters connect to other SMC units in the same series with joiner clamps (sold separately), so you can customize your air preparation system. They’re also known as coalescing filters. To prevent clogs, install a particle filter before the oil filter.

Filters with a filter service indicator let you know when the filter element needs to be changed. The indicator will turn increasingly red as the element clogs.

Joiner clamps (sold separately) create compact, airtight connections between components, even if the pipe sizes are slightly different. They come with mounting brackets to attach the filter to a wall or equipment.

SMC Compressed Air Filter Bowls

Polycarbonate Plastic

Nylon Plastic

Aluminum

Aluminum with Sight Glass

Replace a damaged bowl on your SMC modular compressed air filter, or switch to a different bowl material or drain type. These bowls come with an O-ring to ensure a tight seal.

Bowls with an automatic drain periodically release condensate into the air, eliminating the need for manual emptying.

Aluminum bowls are more durable than plastic bowls, so they hold up better to bumps and drops.

BSPP threads are also known as G threads. BSPT threads are also known as R threads.
