Ductless Fume Hood

Ductless fume hoods, or filtered fume hoods, are self-contained, filtered enclosures that remove hazardous fumes, vapors and particulates from the immediate environment. Typically used in locations where outside ventilation cannot suffice, a ductless fume hood is a necessity to eliminate high percentages of harmful contaminants to protect users, applications and the atmosphere.

There a few key characteristics that distinguish Ductless Fume Hoods from Conventional Ducted Fume Hoods (that typically vent outdoors):

• A “recirculating” air pattern and no external ducting or venting.
• The use of high-quality filtration media.
• Benefits including environmentally-friendly operation, energy efficiency, cost efficiency, minimal maintenance, and mobility.

Why choose AirHawk over other ductless fume hoods?

• 1400 Lux LED Light: The AirHawk has the brightest light in a fume hood in the market! The 1400 Lux LED light provides the operator superior visibility for sensitive or diverse applications such as biological studying, soldering, and pharmaceutical compounding.
  
• User Friendly Control Panel: The AirHawk ductless fume hood control panel features centralized light and fan controls as well as digital displays for air pressure and runtime.
• Adjustable Light & Fan Controls: The ability to adjust the light intensity and fan speed allows the operator to accommodate varied uses and adapt depending on the application requirements. Recording or making note of the fan setting helps an operator optimize the fan speed for distinct preparations or operations.
• Air Pressure Digital Display: The Air Pressure display utilizes a precision solid state pressure sensor to measure the filter saturation by monitoring the static pressure on the particulate filters. Over time as the filter begins to saturate, the air pressure will slowly increase. Once it reaches a certain point the filter should be changed to ensure high filter efficiency. The clear digital display makes it easy to monitor the filter saturation to protect the operator’s health and environmental safety. 
• Runtime Digital Display: The runtime digital display shows the time the fume hood has been in operation in hours. This feature supports accurate time keeping for filter PM schedules and maintenance of the fume hood. When filters are replaced, runtime can be reset to zero for the next cycle.

How does a Ductless Fume Hood work?

1. Operators perform their process in the work area of the hood. The access area at the front of the hood is often referred to as the “sash “. While performing in the work area, fume and particulate emissions from the application are quickly pulled into the filtration system by a powerful fan situated on top of the hood.
2. Air is processed through a pre-filter, which captures some of the particles.
3. Air is passed through the main filter and the majority of contaminants are captures. Main filter options include:
   • HEPA Filter [up to 99.97% efficient on particles 0.3 microns and larger]
   • ASHRAE Filter [up to 95% efficient on particles 0.5 microns and larger]
   • ULPA Filter [up to 99.9995% efficient on particles 0.12 microns and larger]
   • Activated Carbon Filter [efficiency rate varies with the chemical being extracted]
   • Specialty-blended Filters [e.g. Acid Gas, Aldehydes, Ammonia, Mercury]
4. Once filtered, air is distributed back into the immediate environment.

Ductless Fume Hood features and benefits

Environmentally-Friendly: In many cases, ducted exhaust hoods empty extracted fume and particulate directly outdoors without sending it through a filtration system first. Ductless Fume Hoods trap hazardous particulate in filters so they can be disposed of properly.

Energy Efficiency/Cost Efficiency: Ductless Fume Hoods recirculate existing room air, while externally ducting systems remove heated, cooled, or dehumidified air outdoors, which requires that air to be replaced. This has the potential to waste energy and increase cost.

Minimal Maintenance & Installation Requirements/Easy Mobility: While externally ducting exhaust hoods require complicated installation because of ducting construction, Ductless Fume Hoods can be up and running with minimal installation. They are essentially “plug and play” solutions. Ductless Containment Hoods do not require any ducting or external venting and can be moved from location to location with relative ease. The only maintenance requirements are replacing saturated filters and wiping the hood down with appropriate cleaning supplies from time to time.

All specifications are nominal and subject to change without notice. Not intended for explosive or highly flammable applications. (i.e. when the Lower Flammability Limit is exceeded for any given chemical). Please consult the specific MSDS for questions regarding flammability limits.
