Respicefinem 110V 500W PTC Ceramic Air Heater Element

The Respicefinem PTC heating element delivers reliable 110 V, 500 W output for forced‑air heating systems. Built around a ceramic thermistor and a compact aluminum fin assembly, the module transfers heat efficiently to moving air, making it ideal for equipment replacements, custom HVAC projects, and DIY repairs that require a matching voltage and airflow configuration. The element features bare‑wire connections and must be installed by a qualified technician with proper insulation and ventilation.

Thanks to positive temperature coefficient (PTC) technology, the heater self‑regulates: as the ceramic warms, its electrical resistance rises, naturally limiting the temperature rise and protecting downstream components. An integrated 150 °C normally‑closed thermal protector adds an extra safety layer, disconnecting power if the element exceeds its design limit. The compact aluminum housing measures approximately 140 × 50 × 26 mm (5.51 × 1.97 × 1.02 in) and weighs about 165 g, fitting easily into standard mounting slots. Ensure adequate clearances and proper fan or blower flow for optimal performance.
