Description
Product Overview
The Sy-Klone FEFF209 is a high-efficiency RadialSHIELD recirculation filter for RESPA cab systems that rely on clean, recirculated air to maintain operator comfort. With its MERV 16 rating, the filter captures fine particulate before it re-enters the cab’s ventilation system. Because the FEFF209 uses RadialSHIELD sealing technology, it helps prevent bypass air and maximizes filter effectiveness.
Built for demanding heavy-equipment environments, this filter supports HVAC efficiency and helps reduce dust buildup inside the cabin. It installs easily in compatible RESPA recirculation housings used in construction, mining, agriculture, forestry, and waste-handling applications.
