SAN-EI Air Agitator
Pneumatic Air Mixer
The SAN-EI Air Agitator (Air Mixer) is a pneumatic mixing device powered by a compressed-air motor. It is designed for stirring and mixing liquids in industrial tanks and containers. Because the mixer is driven by an air motor rather than electricity, it can operate safely in hazardous environments such as areas with explosive gas, combustible dust, high temperature, or high humidity.
The equipment is compact, lightweight, and easy to operate, making it suitable for many industrial mixing applications.
1 Working Principle
The air agitator operates using a pneumatic air motor connected to a mixing shaft and impeller.
Operating process
-
Compressed air is supplied to the air motor.
-
The air motor converts pneumatic energy into rotational motion.
-
The motor drives the mixing shaft.
-
The impeller rotates inside the liquid tank to stir and mix the fluid.
The rotation speed can be easily adjusted by controlling the air flow.
Users can regulate the air supply through a needle valve to obtain the desired mixing speed.
2 Main Features
Easy Speed Control
The mixer speed can be adjusted simply by controlling the amount of compressed air supplied to the motor.
Safe Operation in Hazardous Areas
Because the agitator uses compressed air rather than electricity, it can safely operate in:
-
explosive gas environments
-
combustible dust environments
-
high-temperature areas
-
high-humidity conditions
Compact and Lightweight Design
The air mixer is small and light enough to be carried by one person, making installation and relocation easy.
Simple Mechanical Structure
The air agitator has a simple structure with few moving parts, resulting in reliable operation and easy maintenance.
3 Typical Components
A SAN-EI air agitator system usually consists of:
-
pneumatic air motor
-
mixing shaft
-
impeller (agitator blade)
-
mounting bracket or clamp
-
air control valve
-
compressed air supply line
These components work together to provide efficient mixing performance.
4 Typical Applications
SAN-EI air agitators are widely used in industries that require safe and reliable mixing operations.
Chemical Industry
Mixing of chemicals, solvents, and additives.
Petrochemical Industry
Agitation of oils, fuels, and other liquid materials.
Paint and Coating Industry
Mixing pigments and coatings in tanks.
Pharmaceutical Industry
Liquid mixing in clean production environments.
Food Processing
Mixing liquids such as syrups or ingredients.
Because air mixers produce no electrical sparks, they are particularly suitable for hazardous environments.
5 Advantages of Pneumatic Mixers
Compared with electric mixers, air agitators provide several advantages:
• explosion-proof operation
• simple speed adjustment
• safe overload behavior
• self-cooling during operation
• compact and portable design
These advantages make pneumatic mixers ideal for industrial environments where safety and flexibility are important.
