🔌 What is a Ductless Fume Hood?
Ductless fume hoods are fume hoods without a duct but with a complete scrubbing solution for the expected output from the reaction carried out inside the hood. This makes them a preferred choice for scientists where external ducting is not possible.
A ductless fume hood protects your personnel and the environment from toxic or volatile chemicals so that you can concentrate on what matters most in your work. Continuous airflow across the work surface draws contamination away from the user, recycling clean air back into your laboratory.
Our ductless fume hoods provide energy savings, safety, and convenience — at the heart of our product line is the innovative Pure Air Filtration Technology that creates a safe work environment over the widest range of applications in the industry.
Research Laboratories: Found throughout research labs worldwide, designed to protect the user and environment from hazardous vapours generated on the work surface.
Educational Facilities: Pure Air Basic ductless fume hoods are found in educational facilities throughout the world — safe, easy to use, and effective.
Forensic Laboratories: Designed to protect the user and the environment from hazardous vapours in sensitive forensic analysis environments.
Package & Mail Inspection / Powder Processing: HEPA filters can also be fitted where particulate or microbial flow is planned.
Industrial Small-Scale Handling: Ideal for laboratory environments where space is limited and only small volumes of harmful substances are handled.
How to Order a Ductless Fume Hood
Ductless fume hoods are typically custom-designed to meet individual requirements. Follow these steps to ensure you receive the right system for your laboratory:
Assess Your Needs
While ductless fume hoods offer more convenience, it’s essential to consider their limitations compared to traditional vented hoods. Certain chemicals or high-volume operations might require a vented system.
Provide Detailed Information
The ductless fume hood is tailored to your specific needs — provide a comprehensive list of chemicals, expected vapours, reaction conditions, and daily usage to ensure perfect operation.
Determine Hood Size
The size of the fume hood should accommodate the equipment and materials you’ll be using. According to those sizes, the size of the fume hood should be planned accordingly.
Customisation is Key
Ductless fume hoods are custom-designed to meet individual requirements. The scrubbing process, filtration method, and operational techniques may vary based on your chemical profile.
Design and Validation
Based on the information you provide, our team will design the ductless fume hood that meets your specific needs. Once constructed, we conduct validation tests to ensure optimal performance and provide a validation protocol for periodic revalidation for regulatory requirements.
By following these steps and working closely with our experts, you can acquire a ductless fume hood that provides a safe and efficient working environment for your laboratory.

Ductless Fume Hood — Step-by-Step Operating Guide
Follow these steps to safely and effectively use your ductless fume hood:
🔐 Preparation
- Wear appropriate PPE: gloves, lab coat, safety glasses
- Clear the work area inside the fume hood of unnecessary items
⚡ Turn On the Hood
- Locate the power switch and turn it on
- The fan starts running, creating downward airflow within the hood
⚗️ Place Chemicals
- Place chemicals inside the fume hood
- Avoid working directly under the airflow
- Keep chemicals organized and labelled
🔬 Start Experiment
- Begin your experiment or procedure
- Keep the sash lowered to capture fumes effectively
📊 Monitor Air Quality
- Regularly check air quality indicators
- If indicators show high contaminants, adjust sash or increase fan speed
🚫 Clean Up
- Carefully clean up any spills or residue
- Dispose of waste materials according to safety guidelines
🔒 Turn Off the Hood
- When finished, turn off the fume hood
- Allow the fan to continue running briefly to filter remaining fumes
Advantages, Selection Guide & Limitations
✓ Advantages
- No External Venting: Eliminates the need for complex ventilation systems, reducing installation costs and simplifying maintenance.
- Portability: Many ductless hoods are portable, allowing them to be easily moved to different locations within a laboratory.
- Flexibility: Can be used for a variety of applications — chemical handling, biological research, and pharmaceutical manufacturing.
- Energy Efficiency: Ductless hoods typically consume less energy than traditional vented hoods.
◆ Selecting for Different Chemicals
- Chemical Type: Determine the type of chemicals you’ll be working with (e.g., acids, bases, organic solvents) before selecting.
- Toxicity: Assess the toxicity level. Highly toxic substances may require more advanced filtration systems.
- Volatility: Consider the volatility. Volatile substances evaporate quickly and may require higher airflow rates.
- Filtration Efficiency: Choose a hood with a filtration system appropriate for the specific chemicals you’ll be handling.
△ Limitations
- Limited Airflow: May have limitations in airflow compared to vented hoods, affecting performance for highly volatile or toxic substances.
- Filter Maintenance: Filters need regular inspection and replacement to ensure optimal performance, adding to maintenance costs.
- Cost: Ductless hoods can be more expensive than traditional vented hoods, especially for larger or specialised models.
