Insulated PTC air heater for 220 V AC systems, available in 750 W or 1000 W power ratings. The unit measures 205 x 80 x 102 mm and uses a PTC thermistor as the heating element to provide fast, stable warming by forced airflow. Key specifications: - Input voltage: 220 V AC. - Power options: 750 W or 1000 W nominal. - Size: 205 x 80 x 102 mm. - Heating material: PTC thermistor. - Heating method: heat radiation via airflow. - Connection cable: high-temperature lead for reliable electrical connection. - Surface insulation: yes. - Construction: PTC element mounted inside an aluminum tube and insulated from the tube surface. Why choose this PTC air heater: - Safe operation due to insulated surface and non-live external surfaces during operation. - Self-regulating PTC material maintains a near-constant surface temperature without complex control electronics. - Fast warm-up time and long service life under normal operating conditions. - Low operating noise suitable for equipment and appliance integration. - Compact form factor and high-temperature cable simplify installation into existing systems. Performance notes and compatibility: - Nominal power values are reference figures; actual heating output depends on installation, airflow, and heat loss. - Expect a performance tolerance of approximately plus or minus 15 percent across different working environments. - Not suitable for applications requiring highly precise current or power accuracy. - Intended for integration into 220 V AC devices and systems that provide forced airflow across the heater. Typical applications and use scenarios: - Incubator temperature support: provides stable, self-regulated heating for small incubators where consistent air temperature is required. - HVAC and warm-air outlets: serves as a compact heating element in small air-conditioning or ventilation units to deliver rapid warm airflow. - Equipment and appliance integration: ideal for automatic heating modules, ticketing machines to prevent condensation, beauty equipment, and various household appliances that require a safe, insulated heating source. Installation guidance: - Install where forced airflow can pass through the heater to ensure effective heat transfer by radiation and convection. - Select the power variant that matches the thermal load and available airflow of the target application. - Use the supplied high-temperature lead for secure wiring and observe standard electrical safety practices during installation. This insulated PTC air heater is a practical, compact heating solution for 220 V AC equipment and appliances that require reliable, self-limiting temperature control and insulated, low-noise operation.
