IDW Service Parts & Accessories
IDW service parts and accessories keep your SMC heatless desiccant air dryer running at its rated dew point. Automation Distribution stocks genuine SMC replacement parts for the IDW Series — service kits, controllers, silencer and muffler kits, purge plugs, foot mounting kits, and filter elements — so you can schedule maintenance without unplanned downtime.
What's in this category
- Service kits — scheduled-maintenance kits matched to dryer model and service interval, available in 12,000-hour and 24,000-hour versions (for example, IDWC35-12000 for the IDW35N, IDWC55DF-24000 for the IDW55N). Replacing desiccant and seals on schedule maintains the dryer's rated pressure dew point.
- Controllers — replacement dryer controllers covering the full IDW range: IDWPDCK01 for IDW04N–35N units and IDWPDCK02 for IDW45N–365N units.
- Silencer & muffler kits — replacement silencer kits (IDWPD1SK01, IDWPD1SK02) and mufflers (IDWPD2SK01) for the dryer's purge exhaust, matched to specific IDW size ranges.
- Purge plugs — IDW-PPK series purge plugs (PPK31, PPK33, PPK37) that set the dryer's purge rate by size and rating.
- Mounting hardware — foot mounting kits such as the IDWFB35 for secure floor installation.
- Filter elements & components — replacement filter elements (66047-2, 66067-2) and components including power cables, keeping the dryer's integral filtration and electrical systems serviceable.
Which part do I need?
SMC IDW parts are matched to specific dryer models and size ranges, so the correct part depends on your dryer's part number. Service kits are tied to both the model and the maintenance interval; controllers, silencers, and mufflers are grouped by IDW size range. If you have your dryer's model number, the SMC IDW series catalog lists the matching service parts — or contact our team with your part number and we'll confirm the right kit.
