WJER-30 Automatic BOV Aerosol Filling Machine 20-30 Cans per Min (Automatic lifting )
Product Introduction
The WJER-30 is a automatic Bag-on-Valve (BOV) aerosol filling machine designed for small to medium batch production. It integrates PLC control and an automatic height adjustment system – no manual intervention needed when switching between different can sizes.
With a production speed of 20–30 bottles per minute and a filling accuracy of ±1%, the WJER-30 delivers consistent results for a wide range of water-based aerosol products, including:Water-based fire extinguishers,Water-based spray paints,Nasal sprays,Deodorant sprays,Olive oil sprays,Shaving gels.
Process Flow

Feature
(1) PLC Control with HMI.User-friendly interface allows easy parameter setting, real-time monitoring, and fault diagnosis. One-touch operation reduces training time and human error.
(2) Automatic Height Adjustment (Patented Design).The machine automatically adjusts its filling and crimping heads to match container height (70–300mm) without any tools or manual recalibration. Changeover between different can sizes takes seconds.
(3) Complete BOV Filling Heads Configuration.1 crimping & gas filling head – seals the valve and charges propellant;2 liquid filling heads – high-efficiency liquid dosing;1 pressure test head – ensures each can meets pressure standards;1 valve cleaning head – removes residue before sealing
(4) High Precision & Flexibility,Filling volume: 30 – 500 ml (customizable);Filling accuracy: ±1%;Container diameter: φ35 – 70 mm;Container height: 70 – 300 mm
(5) Low Air Consumption.Compressed air requirement: 0.6–0.7 Mpa with only 1 m³/min consumption – energy-saving and suitable for small workshops.
(6) Expandable into a Full Production Line;Optional equipment available:Can feeding machine ,Nozzle pressing machine,Cap pressing machine,Packing table.
Detailed Image
Gas Filling & Crimping Head
Gas Filling, then sealing
Equipped with a pressure sensor (precision 0.01MPa) to realize the protection of no-pressure non-sealing, to avoid the waste of package material
Filling head
Liquid Filling Head
Guided forced filling head, precision fixed, filling accuracy control
Pressure Measurement head
Real-time monitoring of the internal pressure of aerosol cans for compliance with standards to ensure product safety
Cleaning Head
The cleaning head can be customized according to customer needs. The main purpose is to clean colored and easily solidified materials. The cleaning medium is the volatilized gas of industrial alcohol and pressurized to clean the remaining material in the valve core to prevent the valve core from clogging.
PLC control
Multi-language interface
Touch screen interface, intuitive and easy to understand, real-time monitoring of the production process, with a three-color alarm light to indicate faults
Dosing Cylinder
Be linked with the filling head to ensure the liquid dosing precision through the piston movement and pressure sensor, and the guided forced filling head reduces the residue.
Turntable
Turntable conveyor system, aerosol cans move steadily in a circular motion without wobbling
