Semi-Automatic BOV Aerosol Filling Machine | AL-BOV

The AILE AL-BOV-A is a compact, bench-style semi-automatic Bag-on-Valve (BOV) filling and crimping machine designed for laboratory formulation, pilot batches, and small-to-medium commercial production. Integrating under-the-cap gas charging & crimping with positive displacement liquid dosing on a unified stainless steel workstation, it allows a single operator to achieve continuous packaging with zero changeover tooling required.

Delivering a stable working output of 500–700 cans/hour (8–12 cans/min), the system uses clean compressed air or nitrogen (N2) as the propulsive medium, completely isolating high-value active ingredients inside a laminated pouch. Controlled by a Siemens PLC and responsive touchscreen, it features a secondary multi-stroke filling mode for high-capacity containers (up to 550ml+). Built with sanitary SUS316L fluid contact pathways for pharmaceutical and cosmetic purity.

Core Machine Highlights:
• Integrated 2-in-1 Workstation: Left Station for Vacuum/Under-the-Cap Gassing & Sealing; Right Station for Through-the-Valve Dosing
• Production Throughput: 500–700 cans/hour (One-operator setup)
• Dosing Flexibility: Single-stroke up to 280 ml (equipped with repeat dosing logic for large cans)
• Tooling Advantage: Fits Ø35–70 mm diameter and 100–270 mm height without swapping starwheels or molds
• Sanitary Execution: Full SUS304 body casing with SUS316L fluid contact components
• Premium Electronics: Siemens PLC & HMI, Schneider air breaker, SMC / AirTAC pneumatics

Semi-Automatic Bag-on-Valve (BOV) Packaging Machine

Compact 2-in-1 Footprint: Designed for boutique personal care brands, pharmaceutical R&D labs, and contract aerosol pilot runs. A single operator comfortably handles 500–700 cans/hour. Integrates under-the-cap propellant charging/crimping and through-the-valve liquid dosing onto a standalone SUS304 table (1000 × 660 mm).

The AILE AL-BOV-A solves the barrier of entry for Bag-on-Valve packaging. While large-scale factories deploy fully automatic BOV filling lines, this semi-automatic system gives emerging producers the same pharmaceutical-grade barrier protection at a fraction of the capital cost. Learn the fundamentals in our guide: What is Bag-on-Valve technology?.

Controlled by an intuitive Siemens PLC and color touchscreen, all critical cycle timings and dosing strokes can be calibrated digitally without mechanical trial-and-error.

Tool-Free Size Changeover

Fits can diameters from Ø35mm to Ø70mm without replacing costly molds. Height is dialed in rapidly using an ergonomic manual handwheel.

Secondary Multi-Fill Function

Equipped with repeat-stroke automation on the touchscreen to fill high-capacity pouches (e.g. 400ml–500ml) without sacrificing dosing precision.

Pharma & Cosmetic Grade Contact

All fluid pathway parts, dosing pistons, and nozzles are machined from certified SUS316L stainless steel, resistant to corrosion and acid formulations.

Safe Low-Cost Operation

Eliminates the danger of flammable hydrocarbons. Powered simply by standard single-phase 220V power and an industrial air compressor.

Common BOV Commercial Applications:

Saline Nasal Sprays Sunscreen Continuous Mists Thermal Spring Facial Waters Gourmet Olive Oil Sprays Wound Wash & Burn Relief Post-Foaming Shave Gels
1. If I change to a different can height or diameter, do I need to purchase extra molds? +
No extra molds are needed. The AL-BOV-A accommodates diameters from Ø35mm to Ø70mm and heights from 100mm to 270mm using universal centering clamps. Height adjustments between different SKU runs are completed in less than 3 minutes simply by turning the top ergonomic handwheel.
2. Do I need an expensive gas storage tank, or can I use an ordinary air compressor? +
A standard industrial air compressor (with basic air drying and filtration to 0.5–0.8 MPa) is completely sufficient for most cosmetic and household BOV products. If packaging pharmaceutical-grade sterile saline or oxygen-sensitive edible oils, the system can connect directly to standard high-purity Nitrogen (N2) cylinders via a dual-stage pressure regulator.
3. How does the machine fill large cans exceeding the 280ml cylinder capacity? +
The Siemens touchscreen includes a dedicated Multi-Stroke Dosing Mode. For instance, to dose 400ml, set the cylinder stroke to 200ml; the machine will automatically inject twice into the same container in one clamping cycle, eliminating the need to custom-order oversized metering pistons.
4. What should I check if liquid drips from the valve or nozzle after filling? +
Occasional dripping after extensive production usually indicates friction wear on the inner nozzle O-ring or cylinder seals. AILE supplies complete backup seal kits with each machine, and our video manuals demonstrate step-by-step seal replacement within 10 minutes without disassembling structural linkages.
5. If our order volume grows, can we easily transition to an automated line? +
Yes. The AL-BOV-A uses the exact same 1-inch valve sealing collet geometry and positive displacement dosing principles as our continuous production platforms. When your monthly throughput expands past 50,000 cans, you can smoothly step up to our automatic BOV packaging lines (50–80 cans/min) while retaining the AL-BOV-A as a flexible pilot or rework unit.
6. Can AILE test our cans, pouches, and liquid formula before we place an order? +
Yes, we strongly encourage sample testing. You can send your empty aerosol cans, BOV valve pouches, and bulk product to our Guangzhou facility. Our engineers will perform live filling, verify inflation pressure retention, and share high-definition testing videos and FAT reports before shipment sign-off.
