WJER-80 BOV Aerosol Filling Line Project for Water-Based Fire Extinguisher

Introduction

This project was completed for a water-based fire extinguisher manufacturer who required an efficient and reliable aerosol filling solution for producing portable fire protection products.

With the increasing demand for lightweight, convenient, and environmentally friendly fire protection products, water-based aerosol fire extinguishers have become an emerging product category in the fire safety industry.

The customer needed a production line that could achieve:

• Stable filling performance

• Accurate liquid and gas filling

• Reliable sealing quality

•  Continuous production capability

Based on the customer's product requirements and production capacity, Wejing designed and supplied the WJER-80 BOV aerosol filling production line solution.

 

1. Project Background and Customer Requirements

The customer is a manufacturer specializing in water-based fire extinguisher products. To improve production efficiency and meet increasing market demand, the customer planned to establish an automated aerosol filling production system.

Compared with traditional fire extinguishing equipment, water-based aerosol fire extinguishers have advantages including:

· Lightweight packaging

· Easy operation

· Clean discharge

· Low residue

· Convenient storage

However, producing this type of product requires specialized filling technology and precise process control.

(1) Accurate Filling of Water-Based Extinguishing Agent

The customer's products contain water-based extinguishing formulations, including:

· Water

· Fire suppression additives

· Foam agents

· Functional chemical components

These materials require accurate filling control to ensure consistent product performance.

(2) Separation Between Product and Propellant

Traditional aerosol filling methods usually mix product and propellant directly.

For water-based fire extinguishing products, the customer required a filling method that could separate:

· Extinguishing liquid

· Propellant gas

Therefore, BOV (Bag-on-Valve) technology was selected as the ideal solution.

(3) Stable Mass Production Capability

The customer required a production line with:

· Continuous operation

· Stable output

· Reliable sealing

· Easy maintenance

2. Wejing WJER-80 BOV Aerosol Filling Production Line Solution

According to the customer's product characteristics and production requirements, Wejing provided a customized WJER-80 BOV aerosol filling production line.

The complete system integrates:

· Aerosol can conveying system

· BOV valve installation system

· Gas filling system

· Liquid filling system

· Sealing system

· Automatic control system

The production line was specially designed for water-based aerosol fire extinguisher manufacturing.

(1) BOV Filling Technology Application

The WJER-80 production line adopts Bag-on-Valve technology.

The structure allows the extinguishing liquid to remain inside the inner bag while the propellant gas stays outside the bag.

This design provides:

· Better product stability

· Cleaner spraying performance

· Reduced contamination risk

(2) Automated Production Process

The integrated production line reduces manual operation and improves production efficiency.

The complete process includes:

· Can feeding

· Valve installation

· Gas filling

· Liquid filling

· Sealing

· Product inspection

(3) Customized Equipment Configuration

Wejing customized the production solution according to:

· Product formula

· Container size

· Production capacity

· Factory layout

 

3. Production Process of WJER-80 BOV Aerosol Filling Line

The WJER-80 production line completes the entire aerosol filling process through several automated steps.

(1) Aerosol Can Feeding

Empty aerosol cans are transferred into the production line through the conveyor system.

The feeding system ensures:

· Stable transportation

· Accurate positioning

· Continuous production

(2) BOV Valve Installation

The Bag-on-Valve system is accurately installed onto the aerosol can.

The valve separates:

· Water-based extinguishing agent

· Propellant gas

This improves product stability and spray performance.

(3) Gas Filling and Sealing

Compressed air or nitrogen is filled into the space between the bag and the can.

The system provides stable pressure control to ensure consistent spraying performance.

(4) Liquid Filling

The water-based extinguishing agent is accurately filled into the inner bag.

This process prevents direct contact between the product and propellant.

(5) Quality Inspection

The finished products can be inspected for:

· Filling accuracy

· Sealing quality

· Pressure stability

 

4. Technical Features of WJER-80 Production Line

 

5. Project Advantages and Results

The WJER-80 BOV aerosol filling production line provides the customer with an efficient and reliable manufacturing solution.

(1) Improved Production Efficiency
