4.5L Electric ULV Fogger With Automatic Spraying

The 4.5L portable fogger features a frequency-conversion motor that adjusts output flow and a fixed valve that tilts up to 60 degrees for flexible spray patterns. It emits 20-50 micron droplets (average around 30 microns), enabling rapid coverage across greenhouses or large indoor spaces. The unit is designed for easy filling and operation; the 16.6-foot power cord supports mobile positioning, and the automatic spraying mode minimizes manual triggering for continuous misting. This model is well suited for disinfecting, humidity management, and general area fumigation in controlled environments.
Hurricane Ultra II ULV Fogger

Built for professional reliability, the Hurricane Ultra II ULV fogger is designed in the USA and has earned trust for over two decades. Its rugged construction supports both oil- and water-based products, making it versatile for greenhouse sanitation and pest control. The device includes precision nozzles—three chemical-resistant outlets—to maximize output while maintaining control over droplet dispersion. The high-performance blower ensures wider droplet reach, enabling faster coverage of greenhouse bench rows and larger rooms. This model emphasizes durability and consistent performance in demanding environments.
LONYEON 8L Backpack ULV Fogger

The LONYEON 8L ULV fogger features a backpack design that distributes weight for extended operations, making it suitable for covering larger greenhouse areas. It offers an 8-liter tank with a long spray range, a corrosion-resistant spray head, and a flexible hose that enables adjustments mid-use. The adjustable flow and a 40-foot atomization distance provide strong versatility for reaching corners and dense plant blocks. A user-friendly handle-mounted ON/OFF switch and easy refilling further support efficient, continuous misting over extended sessions.
ULV Fogger 7L Portable Sprayer

This 7-liter ULV fogger is designed for both indoor and outdoor use, offering a large capacity with a vertical design that helps balance weight for manageable handling. It includes a wide spray range—suitable for disinfecting and deodorizing large greenhouse spaces. The unit is intended for simple refills and continuous operation, with a focus on reliability in professional settings. The accompanying features emphasize broad coverage and ease of transport, making it a practical option for larger greenhouses or multi-room facilities.
5L ULV Fogger Sprayer With 3 Nozzles

This model uses three precision nozzles to deliver an ultra-fine mist up to 30 feet, enabling broader coverage with reduced solution waste. The 5-liter tank supports longer spraying sessions, ideal for large greenhouses or multiple high-value beds. The spray head tilts up to 60 degrees to facilitate indoor spraying, while the adjustable flow rate (150–330 ml/min) provides control for delicate misting or strong outdoor application. The design aims to balance efficiency with portability for frequent use around the workspace.
Buying Guide: Key Considerations For Greenhouse Fogger Purchases
- Tank capacity and spraying duration: Larger tanks extend operation between refills, reducing downtime during routine misting or sterilization. Consider whether a backpack design or handheld unit better fits your greenhouse layout.
- Droplet size and spray distance: Fine droplets (roughly 20–50 microns) provide thorough coverage without excessive wetting. Longer spray distances help reach back corners and dense plant blocks.
- Flow rate and nozzle options: Adjustable flow and multi-nozzle configurations let you tailor output for different tasks, from delicate humidity control to aggressive sanitization.
- Portability and ergonomics: Backpack models distribute weight for all-day use, while compact units offer quick maneuverability in tight spaces between benches.
- Power and cord length: A sufficient cord length or battery-assisted options improve reach across larger greenhouses. Check for convenient on-handle controls when possible.
- Material compatibility: Choose units designed to handle water- or oil-based formulations without corrosion to ensure long-term durability in humid environments.
- Maintenance and replacement parts: Simple disassembly and accessible replacement nozzles or seals reduce downtime and extend the life of the fogger.
- Safety and compliance: Ensure the device meets local safety standards and that you follow label guidance for chemical misting to protect workers and plants.
In greenhouse settings, selecting an ULV fogger involves balancing capacity, portability, and spray control. For large spaces, models with backpack design and adjustable droplet outputs can provide the most efficient coverage. Smaller or multi-room facilities may benefit from handheld units with automatic spraying mode for continuous misting during sanitation cycles. Consider how often you’ll use the device, the types of formulations applied, and the layout of your greenhouse when making a final choice.
