Heated air source using non-magnetic nickel-chromium wire, clean and hygienic, in compliance with environmental protection standards. Equipped with a dry-burn and breakage prevention feature.

Smart wind tunnel design, air passes evenly through the inside and outside of the spiral heating wire, achieving nearly 100% heat exchange, with minimal pressure loss and low flow rate.

PID/SSR control with high accuracy, fast feedback, durable for long-term use, multiple protective devices, suitable for continuous 24/7 operation.

The air outlet is equipped with a K-type thermocouple for direct detection and control, ensuring a constant outlet temperature.

Stainless steel housing, safe and reliable, suitable for high-temperature operation.

Continuous operating temperature up to 350℃/500℃/650℃ below, widely applicable.

Power options include 3KW/5KW/7.5KW (up to custom-made 10KW); also available with an intelligent remote control switch for added convenience upon request.

The portable mini hot air blower is mainly composed of three major parts: an internal centrifugal fan, a heater, and a control circuit.

Distinguish between internal and external installation of blowers: Built-in blower type and external gas source type:

Built-in Fan Type: Equipped with an internal fan, the air volume and pressure can be adjusted as needed, suitable for continuous operation.

External gas source type: Requires an external gas source, which can be a medium-pressure blower or compressed air, suitable for fixed or intermittent product use.

1. Working Principle

The operation principle is as follows: Once powered, the axial flow blower blows air into the heater, allowing the air to pass evenly through both the inner and outer sides of the spiral tube wound with electric heating wires. The electric heating wires heat the passing cold air (the temperature range of the small heat fan is: room temperature - 250°, if a higher temperature is required, please specify at the time of order). The K-type thermocouple at the outlet continuously feeds back the outlet temperature to the temperature control instrument (the temperature reading of the thermocouple is the set value used for actual temperature control), which monitors the actual operating temperature based on the set temperature and sends relevant information back to the solid-state relay to control whether the heater operates. At the same time, the axial flow blower can adjust the air volume by using a voltage regulator, thereby achieving control over both the operating temperature and air volume.
