what is a high-pressure blower？

High pressure fan (also known as high-pressure blower, vortex air pump, side flow fan) is a type of general-purpose industrial air pump that can output high air pressure. It relies on the high-speed rotation of the impeller to repeatedly boost the air and output high-pressure airflow. It can blow air or vacuum suction, and is a commonly used air source equipment for equipment matching

Working principle of high-pressure fan

The motor drives the impeller to rotate at high speed, and air enters the pump body, making a spiral circulation motion between the impeller and the side channel; Every time the impeller blades pass through, they are accelerated and compressed. After multiple repetitions, the pressure increases significantly and is finally discharged from the outlet; The air inlet can create negative pressure, achieving suction and vacuum functions. Characteristics: High pressure, low air volume, opposite to ordinary high flow centrifugal fans.

Main characteristics of high-pressure fan

1. Dual use of blowing and suction: one end for air blowing (positive pressure blowing), one end for air intake (negative pressure suction), dual-use for one machine.
2. Oil free output of clean air: The pump does not require oil lubrication, and the output gas does not contain oil stains, making it suitable for food and packaging.
3. Compact structure and small volume, aluminum die-casting shell, easy installation, no need for complex foundations, can operate continuously for 24 hours.
4. The only consumable parts are bearings, with minimal daily maintenance; Can be used in explosion-proof and anti-corrosion versions.
5. Pressure range: commonly 10-100kPa for vortex high-pressure fans; Dual level models have higher pressure.

Attention: High pressure fan ≠ Roots fan. Roots blower belongs to positive displacement blower; The vortex high-pressure fan belongs to the regenerative side flow type, and their principles, prices, and applicable working conditions are different.

Common application scenarios of high-pressure fans

1. Environmental protection/organic fertilizer equipment: aeration mixing, dust removal and back blowing, material pneumatic feeding and conveying, and supporting gas supply for flipping and throwing.
2. Adsorption fixation: Vacuum adsorption for engraving machines and packaging machines.
3. Water treatment: aeration and oxygenation of sewage tanks.
4. Material transportation: plastic particles, powder suction feeding.
5. Blow drying and water removal: Blow water and dry the workpieces on the assembly line.
6. Printing PCB、 Filling equipment.
