The RTi DE401 Cartridge is a precision-engineered replacement desiccant element designed for the RTi DE-series desiccant dryers. Featuring activated alumina desiccant beads and a fast-change polycarbonate cartridge design, it efficiently removes water and water vapour to help you maintain clean, dry air in automotive paint booths, industrial air systems and compressed-air networks.
Ensure your compressed air remains ultra-dry and contaminant-free with the RTi DE401 Cartridge — a high-quality replacement desiccant element crafted for rugged performance and easy servicing. Built to support the reliable operation of RTi’s DE-series dryers (such as model “DE401-M04” and other DE-series configurations) that deliver up to 25 SCFM in cartridge-type deployment, this element utilizes activated alumina desiccant beads housed in a durable polycarbonate cartridge.
The polycarbonate cartridge design eliminates the need for loose desiccant beads that could migrate into your system, while providing tool-free cartridge replacement in under two minutes. By installing the DE401 on schedule, you protect your spray equipment, pneumatic tools and paint finishes from moisture and water-related defects—ensuring better results and fewer maintenance disruptions.
The DE401 Cartridge is engineered for use in the RTi DE-series desiccant dryers rated for up to ~25 SCFM (half-inch port versions) and other cartridge-type models with built-in dew-point indicators. For example:
RTi DE401-M04 (½″ port, cartridge type, 25 SCFM)
Other “DE” prefix models within the RTi/Reading Technologies product line (check your model label for compatibility with element part DE401)
