Ductless Fume Hood is a viable alternative to conventional fume hoods. This type of fume hood utilizes carbon or HEPA filtration to protect laboratory personnel from toxic chemical fumes, odors, and particles. Known for its plug-and-play feature and mobility, Ductless Fume Hood guarantees a hassle-free installation and no lab work interruption.
Esco Ascent™ Ductless fume hood is known as the "green" solution to Modern Chemistry. This cabinet is equipped with Nanocarb™ filters which removes chemical vapors from the workzone. Also, it has multiple models, configurations, and filter options to suit user's application.
Must-have features to consider:
- Compliance to ASHRAE 110 for superior fume containment
- Effective carbon filtration efficiency
- Easy-to-use control system with alarms for unsafe conditions
- Wide selection of carbon filter types to accommodate a variety of chemical handling
- Plug-and-play feature which prevents any laboratory downtime
- Offers a broad range of accessories and options
- Industry-unique dual diffuser system that helps optimize carbon filter life
- Energy-efficient design which reduces total carbon footprint
- Must be mobile, portable, and easily relocated
- FiltraCheck™ free service to qualify your application's suitability for a ductless solution

If application involves, transferring, dilution, titration and no force evaporation, Ascent™ Max ductless fume hood with Nanocarb™ carbon filter type B is recommended.
If application involves heat and these acids are used frequently with high volume, Frontier™ Acid Digestion ducted fume hood (EFQ) is recommended. This is a specialized ducted fume hood designed to withstand acids and high temperatures.
FiltraCheck™ is a free chemical service assessment that helps customers determine the proper ductless fume hood model and appropriate filter based on their application. This chemical evaluation also estimates the carbon filter life. Customers need to fill up the FiltraCheck™ Form. After which, they will receive an advice with the suitable fume hood solution.
Ascent™ Max ductless fume hoods have an option of adding a VOC sensor. This sensor activates audio-visual alarms when the carbon filter is nearing saturation. For Ascent™ Opti ductless fume hoods, there is a built-in sample port where color detection tubes can be used to manually determine filter saturation.
Gas detectors such as Draeger Accuro pump or RAE meter are also recommended. These apparatus are placed above the exhaust flow to test the concentration of the gases/chemicals present. The actual ppm is checked against the OSHA guideline for PEL (Permissible Exposure
Limit). If it’s still comfortably below the limit, the carbon filter is still effective.

loads or Apparatus not more than 40 kg
Yes, the ductless fume hood can be operated 24/7 but this may cause rapid filter saturation.
Ductless fume hoods are designed for handling chemicals and not for storage. The proper storage for chemicals is in a designated base cabinet or mobile cart, both of which are available as options for Ascent™ Ductless fume hoods.
Ascent™ Max ductless fume hood uses real-time airflow sensing. As soon as the fan capacity is reached, the airflow starts to deteriorate resulting in an “Air Fail” indicating that the filter needs to be checked
No, a fume hood is containment device used to protect the user from inhaling toxic fumes and vapors. Forced evaporation of chemical waste is strictly prohibited because it can saturate the filter faster and may affect the containment.
Yes, different apparatus may be used as long as it will not block the perforations at the back wall. Also, make sure that the dimensions will have at least a 100 mm clearance to avoid airflow disruption.
For safety purposes, Ascent™ Max ductless fume hood does not have an auto shut-off feature. Instead, users can set the 'exp timer' that serves as a countdown timer. It will display "TIMER COMPLETE" and alarm once the countdown is over.
No due to lack of space. The fluorescent lamp is found at the front panel, away from the work zone and therefore, not exposed to fumes and vapors.
The sash handles are constructed from a metal with chrome plating for aesthetic and durability purposes.
