San-ei Air Mixer

SAN-EI Air Agitator

San-ei  Air Hoist  Air Motor  Air Winch  Air Balancer Air Mixer  Air Cranes

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

1. Compressed air is supplied to the air motor.

2. The air motor converts pneumatic energy into rotational motion.

3. The motor drives the mixing shaft.

4. 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.

SAN-EI Air Balancer

San-ei  Air Hoist  Air Motor  Air Winch  Air Balancer Air Mixer  Air Cranes

Pneumatic Load Balancer System

The SAN-EI Air Balancer, branded as “MY HAND”, is a pneumatic lifting and balancing device powered by compressed air. It is designed to allow operators to lift, lower, and move heavy loads smoothly with minimal effort, effectively acting as a “right hand” for material handling operations.

Unlike conventional lifting equipment, the air balancer automatically adjusts the lifting force according to the weight of the load, enabling safe and precise handling of heavy objects in industrial environments.

---

1 Main Features

Labor-Saving Operation

The air balancer allows heavy objects to be moved easily using only one hand, greatly reducing operator fatigue and improving working efficiency.

Automatic Load Detection

A built-in load detection system senses the weight of the workpiece and automatically adjusts the air pressure to balance the load.

Simple Weight Measurement

A simple scale integrated into the balancer enables operators to estimate the approximate weight of the object being lifted.

All-Air Powered System

All operations are driven purely by compressed air, eliminating electrical sparks and making the equipment safe for explosive or hazardous environments.

Simple and Lightweight Design

The mechanical structure is simple and compact, resulting in a lightweight system that is easy to install and maintain.

---

2 Working Principle

The air balancer operates based on a pneumatic balancing mechanism.

Operating process

1. A workpiece is attached to the hook of the balancer.

2. When the operator lifts the object, a load detector senses the weight.

3. The detector sends a pressure signal corresponding to the load weight.

4. The air cylinder generates an upward pulling force equal to the weight of the load.

5. The load becomes balanced, allowing the operator to move it freely in vertical or horizontal directions.

Because the lifting force continuously adjusts to the load weight, the object can be manipulated smoothly and safely.

---

3 Operating Conditions

Typical operating parameters include:

Air supply pressure:
0.3 – 0.6 MPa

Installation location:
Indoor use recommended

Installation time:
Most air balancer systems can be installed within one day, depending on the configuration.

---

4 Typical Models

SAN-EI provides different air balancer models depending on the required load capacity.

Example Models

BTA80A-S
BTA120A-W
BTA Series (various capacities)

These models vary in:

• maximum suspension load

• lifting stroke

• air consumption

• mounting configuration.

The exact specifications depend on the model and application.

BTA120A	2138	1500	120	0.3〜0.6	360

---

5 System Components

A SAN-EI air balancer system usually includes:

• Pneumatic cylinder

• Load detector

• Control valve

• Hook or suspension device

• Air supply line

• Mounting structure

These components work together to provide precise load balancing and lifting.

---

---

7 Advantages Compared with Conventional Lifting Devices

Air balancers provide several advantages over traditional lifting systems:

• easy one-hand operation

• precise load control

• improved workplace safety

• reduced worker fatigue

• explosion-proof operation

SAN-EI Air Winch 

San-ei  Air Hoist  Air Motor  Air Winch  Air Balancer Air Mixer  Air Cranes

Pneumatic Winch Product Series

SAN-EI Air Winches are pneumatic lifting and pulling devices driven by compressed air motors. These winches are designed for heavy-duty industrial operations where safety, reliability, and explosion-proof performance are required.

Because the winch operates using compressed air instead of electricity, it can work safely in areas where electrical equipment may pose a risk, such as explosive environments or locations without power supply.

SAN-EI offers a range of W-series air winches, which are compact, lightweight, and easy to operate while providing strong pulling capacity for industrial applications.

---

1 Main Features

Explosion-Proof Operation

Air winches are powered by compressed air and do not generate sparks, making them suitable for hazardous environments such as chemical plants and oil facilities.

Compact and Portable Design

The winch is designed to be compact and lightweight, allowing easy movement and installation in different working environments.

Reliable Pneumatic Motor

SAN-EI winches use robust radial piston air motors with oil-bath lubrication to ensure durability and stable performance.

Low Air Leakage

The operating section uses poppet valves, which minimize air leakage and improve operational efficiency.

Flexible Speed Control

The air flow from the control valve can be adjusted through the valve handle, allowing smooth control of winch speed.

High Safety Performance

Both manual and automatic systems use band brake mechanisms to ensure safe braking during operation.

Durable Construction

Bearings are fully sealed to prevent oil leakage and ensure long service life.

---

2 Structure and Working Principle

SAN-EI air winches consist of several main components:

• Pneumatic air motor

• Gear reduction mechanism

• Winch drum

• Control valve system

• Brake mechanism
