aerosol filling Production Line: Complete Manufacturing Process Explained
2026-09-02
Choosing the right BOV aerosol Filling Machine depends on your product, valve size, container type, filling volume, and production needs.
If you are looking for a semi-automatic BOV filling machine, this guide will help you quickly compare the main options.
What Is a BOV Aerosol Filling Machine?
BOV stands for Bag-on-Valve. In BOV packaging, the product is separated from the propellant by a flexible bag.
This system is widely used for water-based aerosol products.
For BOV filling, the typical process is:
Gas filling and sealing → Liquid filling
The right machine should match your product and packaging specifications.
5 Semi-Automatic BOV Filling Machines
1. WJER-300S – Split-Type BOV Filling Machine
The WJER-300S uses two separate machines for gas filling/sealing and liquid filling.
This design is suitable for customers who need separate filling stations and a flexible production setup.
Main specifications:
Capacity: 10–15 cans/min
Liquid filling range: 30–300 ml
Gas filling accuracy: ±0.03 MPa
Liquid filling accuracy: ≤±1%
Can diameter: 35–70 mm
Can height: 70–330 mm
Valve: 25.4 mm (1" BOV)
Propellant: N₂ or compressed air
2. WJER300 – Compact BOV Filling Machine
The WJER300 combines the gas filling/sealing head and liquid filling head on one worktable.
It is a practical choice for standard 1-inch BOV aerosol products.
Main specifications:
Capacity: 10–15 cans/min
Liquid filling range: 30–300 ml
Gas filling accuracy: ±0.03 MPa
Liquid filling accuracy: ≤±1%

Can height: 70–330 mm
Valve: 25.4 mm (1" BOV)
3. WJERZ300 – Outer-Crimping BOV Filling Machine
The WJERZ300 uses an outer-crimping sealing method.
It is especially suitable for applications using plastic bottles, where the sealing method is an important consideration.
Main specifications:
Capacity: 10–15 cans/min
Liquid filling range: 30–300 ml
Gas filling accuracy: ±0.03 MPa
Liquid filling accuracy: ≤±1%
Can diameter: 35–70 mm
Can height: 70–330 mm
Valve: 25.4 mm (1" BOV)
4. WJERZ-150 - 20mm BOV Filling Machine
This machine is designed for 20mm BOV valves.
It is suitable for smaller containers and products with a relatively small filling volume.
Main specifications:
Capacity: 10–15 cans/min
Liquid filling range: 2–60 ml
Gas filling accuracy: ±0.03 MPa
Liquid filling accuracy: ≤±1%
Can diameter: 25–35 mm
Can height: 58–330 mm
Valve: 20mm BOV
Propellant: N₂ or compressed air
5. Shaving Gel Aerosol Filling Machine
This machine is specially designed for shaving gel aerosol products and applications requiring a post-foaming process.
It supports a larger liquid filling range of up to 650 ml.
Main specifications:
Capacity: 300–600 cans/hour
Liquid filling range: 30–650 ml
Gas filling accuracy: ±0.03 MPa
Liquid filling accuracy: ≤±1%
Can diameter: 35–70 mm
Can height: 70–330 mm
Valve: 25.4 mm (1" BOV)
Pentane adjustment: 5–60 ml
How to Select the Right BOV Filling Machine
Before choosing a machine, check these key factors:
1. Valve size
Is your product using a 20mm or 25.4mm (1") BOV valve?
2. Container type
Check whether you are using plastic bottles, aluminum cans, or tinplate cans.
3. Filling volume
Make sure the machine's filling range covers your required volume.
4. Product type
Different products may require different filling and foaming processes.
5. Production capacity
Choose a machine according to your required daily output.
Quick Comparison
Machine | Key Feature | Filling Range | Valve |
WJER-300S | Split-type design | 30–300 ml | 25.4 mm |
WJER300 | One-table design | 30–300 ml | 25.4 mm |
WJERZ300 | Outer crimping | 30–300 ml | 25.4 mm |
20mm Bov Machine | Small BOV valve | 2–60 ml | 20 mm |
Shaving Gel Machine | Post-foaming | 30–650 ml | 25.4 mm |
Final Thoughts
Choosing a BOV aerosol filling machine is not only about price or speed.
The most important factors are:
Product → Container → Valve → Filling Volume → Sealing Method → Production Capacity
By matching these requirements with the right machine, you can achieve more stable filling and a more efficient production process.
