Here at Holliday Technical Services (HTS), we understand the importance of safety in laboratory environments. That's why we're happy to address your concerns about Ductless Fume Cupboards (DFCs) in this FAQ.

Short answer: DFCs can be just as safe as traditional ducted fume cupboards when used correctly and chosen for the appropriate applications. Here's why:

• Matched to the application: The key to Ductless Fume Cupboard (DFCs) safety lies in selecting the right filter for the specific chemicals and volumes you'll be working with. HTS experts can guide you through this process.
• Effective filtration: Modern DFCs utilise high-performance filters like activated carbon, HEPA, and ULPA to capture fumes and particulates efficiently.
• Regular maintenance: Like any fume cupboard, proper maintenance and testing are crucial for optimal safety. HTS offers nationwide DFC servicing to ensure your unit functions effectively.

However, Ductless Fume Cupboards might not be ideal for every situation:

• Highly toxic or explosive chemicals: In such cases, a ducted fume cupboard offering direct exhaust to the outside might be necessary.
• Large volumes of chemicals: The capacity of DFC filters is finite, so they may not be suitable for high-volume fume generation.

At Holliday Technical Services (HTS), we understand the importance of choosing the right filters for your Ductless Fume Cupboard (DFC). Here's a breakdown of the available options and how to select the best fit for your needs:

Types of DFC Filters:

• Activated Carbon Filters: Ideal for capturing a wide range of chemical fumes and odours. Choose from specific carbon types tailored to your chemicals for optimal performance, see our chart on this page.
• HEPA (High-Efficiency Particulate Air) Filters: Capture 99.97% of airborne particles down to 0.3 microns, suitable for dust, aerosols, and biological agents.
• ULPA (Ultra-Low Penetration Air) Filters: Offer even higher efficiency, capturing 99.9995% of particles down to 0.12 microns, for the most demanding filtration needs.

Choosing the Right Filter:

Selecting the correct filter depends on two key factors:

1. Chemicals you're using: Different chemicals require specific filter types for effective capture. Refer to manufacturer's recommendations or consult with HTS experts for guidance.

Here at Holliday Technical Services (HTS), we prioritise safety in all laboratory environments. Knowing when to replace your Ductless Fume Cupboard (DFC) filter is crucial for maintaining optimal protection. Let's explore the different methods you can utilise:

Built-in Filter Saturation Alarm:

Most modern DFCs come equipped with filter saturation alarms, which automatically alert you when the filter needs replacing. This is the most reliable and recommended method for monitoring filter life. Pay close attention to these alarms and promptly change the filter as indicated.

Additional Monitoring Techniques:

While the built-in alarm is crucial, consider these additional methods for a layered approach:

• Airflow Meter: Use an anemometer to measure the airflow velocity at the fume cupboard face. A decrease in airflow can indicate filter saturation.
• Sniffer Test: For certain chemicals, use a specialised "sniffer" tool to detect if fumes are escaping the filter, potentially indicating filter saturation.
• Headaches, Tiredness or Chemical Odour: If lab users complain of headaches, tiredness or you can smell chemicals being used, it could be a sign that your fume cupboard filters are saturated and need replacing.
• Regular Maintenance Schedule: HTS offers comprehensive DFC maintenance plans that include filter inspection and replacement based on manufacturer recommendations and usage patterns.

Remember:

• Timely Filter Replacement: Replacing saturated filters ensures they continue to effectively capture harmful fumes and protects your lab environment.
• Expert Guidance: Unsure about filter life or replacement? Contact HTS for expert advice and nationwide filter replacement services.
