Introduction to Advanced Cleanroom Disinfection
The challenge of maintaining sterile environments in healthcare, pharmaceutical manufacturing, and research laboratories has long been hampered by inefficient disinfection methods.

The Mini-DryFog® Machine represents a significant leap forward in disinfection technology, offering a solution that is both highly effective and user-friendly.
What is a Mini DryFog® Machine?
The Mini-DryFog® Machine provides an easy-to-use, high-tech solution for fogging in confined spaces.

Its flexible nozzle design enables rapid vapor dispersion, ensuring complete coverage of disinfecting vapor throughout the target area. This revolutionary approach transforms how facilities maintain sterility in critical environments.
How Does the Mini Dry Fog System Work?
The Mini Dry Fog System operates by generating ultra-fine droplets—typically less than 10 microns in diameter—using compressed air and specialized nozzles.
These droplets remain suspended in the air as a true “dry fog,” allowing them to uniformly fill the cleanroom environment without wetting surfaces or sensitive equipment.

As the fog disperses, it effectively reaches hard-to-access areas, making it ideal for decontamination and humidity control.
The system is engineered for minimal chemical use while maximizing coverage, helping facilities meet strict cleanroom standards with greater efficiency and consistency.
Designed for Confined Spaces
A single Mini-DryFog® unit is suitable for disinfecting room volumes of up to 20M³ (700 ft³) using just 500 mL of Minncare liquid disinfectant solution. This makes it ideal for:
- Biological safety cabinets
- cRABS (Closed Restricted Access Barrier Systems)
- Glove boxes

- Pass-through tunnels
- Ambulances
- Small cabinets
- H₂O₂ vaporization systems.
Key Benefits of the Mini-DryFog® Technology

Elimination of Hazardous Formaldehyde
One of the most significant advantages of the Mini-DryFog® Machine is its ability to eliminate formaldehyde disinfection procedures. Formaldehyde is a known carcinogen that poses serious health risks to personnel. By transitioning to the Mini-DryFog® system, facilities can maintain sterility while protecting their staff from harmful chemical exposure.
Remarkable Speed and Efficacy
The Mini-DryFog® Machine has been proven effective in killing coronavirus aggressively within just one minute. This rapid action dramatically improves safety protocols in critical environments where contamination control is essential.
Advanced Configurable Spray Technology
The newly designed spray apparatus features eight different nozzle positions, significantly increasing coverage possibilities and flexibility.

This innovative design allows for both horizontal and vertical spray diffusion, ensuring that no surface or corner remains untreated.
Optimizing Operational Efficiency
Dramatic Reduction in Process Time
Typical disinfection cycles with the Mini-DryFog® Machine can be completed in less than 3 hours, depending on room size and ventilation system efficiency.

This represents a remarkable improvement over conventional systems that may require 3-5 days to achieve similar results.
The benefits of this shortened disinfection cycle include:
- Substantially lower clean room downtime
- Increased operational capacity
- Improved production scheduling
- Enhanced facility utilization.
Maintaining Environmental Quality
Regular use of the Mini-DryFog® Machine may contribute to maintaining low particulate levels due to the suppression of airborne particles.

Additionally, the system operates with minimal noise and ultrasonic vibration, creating a more comfortable work environment while maintaining rigorous disinfection standards.
Ideal Applications
The Mini DryFog® Machine is suitable for a variety of controlled environments, including:
- Pharmaceutical Cleanrooms
- Semiconductor Manufacturing

- Biotechnology Laboratories
- Medical Device Assembly Rooms
- Hospital Sterile Processing Areas.
