Engineered for precision and performance, this 700W tangential crossflow blower delivers a remarkably uniform and wide-span airflow across its entire outlet, setting it apart from traditional centrifugal or axial fans. Operating on a standard 220V power supply, this robust unit is designed to provide consistent, low-turbulence air distribution with minimal noise, making it an ideal choice for applications where even air coverage and quiet operation are paramount. Its compact cylindrical design allows for seamless integration into space-constrained equipment without compromising on output efficiency.
Our Silent Cross-flow Fan PTC Heater is a compact, high-efficiency heating module that combines a PTC ceramic heating element with an integrated cross-flow blower fan. Engineered for whisper-quiet operation, this unit delivers powerful, uniform warm air circulation across a wide range of appliances. Available in 600W, 900W, 1200W, and 1800W configurations, it offers flexible heating capacity to suit different cabinet sizes and temperature requirements. The cross-flow fan design ensures a broad, even airflow pattern, making it an exceptional choice for applications that demand silent, stable, and safe heating.
This wall‑mounted boiler blower is a high‑performance centrifugal fan designed for heating boiler systems. Rated at 32W, 220V 50Hz, it adopts stainless steel‑related metal housing structure. Compact and robust construction delivers stable air supply for combustion supporting and exhaust. Two viewing angles show the front air inlet and the side with complete motor assembly, presenting the full mechanical structure of the blower unit.
The 200W 220V Mini PTC Air Heater with Fan is a compact and efficient heating solution designed for small-space applications. Combining self-regulating PTC (Positive Temperature Coefficient) ceramic heating technology with an integrated fan, this unit delivers consistent, forced-air warmth in a space-saving design. Operating at 220V with a 200W power rating, it provides reliable, energy-efficient heating ideal for personal or targeted use.
This silent cross‑flow PTC heater runs on 220V power, with power options of 350W and 353W. It integrates cross‑flow fan assembly and PTC heating module. Designed to match boiler heat exchangers, it delivers uniform, stable warm airflow. The shaded‑pole motor drives the cross‑flow roller fan, cooperating with fin‑type PTC heating element for rapid and safe heating performance.
Our Corrugated Electric PTC Air Heater is a high-performance, self-regulating heating solution designed specifically for industrial and commercial drying applications. Available in power ratings of 1000W, 1500W, 1600W, 1800W, and 2000W at 220V, this heater delivers consistent, energy-efficient heat output with enhanced safety and longevity. The corrugated fin design maximizes surface area for superior heat dissipation, making it an ideal choice for clothes dryers, drying cabinets, and oven-type drying boxes.
Upgrade your heating and cooling systems with our high-performance Cylindrical Small Fan Motor Convection 12V 24V DC Cross Flow Fan Blower. Engineered for precision airflow, this compact yet powerful tangential blower is designed to deliver consistent, linear air distribution across a wide surface area. Whether you are building a custom fireplace insert, enhancing a wood stove, or improving HVAC equipment, this DC cross flow fan provides the reliability and efficiency you need for demanding thermal management applications
The stainless steel NTC temperature sensor is an NTC (Negative Temperature Coefficient) thermistor temperature probe enclosed in a stainless steel housing. It combines the high sensitivity of the NTC thermistor with the excellent mechanical strength and corrosion resistance of stainless steel, making it a durable temperature sensing device widely used in complex industrial environments. Its core operating principle is to accurately detect temperature by measuring the change in resistance, which decreases exponentially with increasing temperature.
