70″ Wide Ductless Fume Hood with One Air Cleaner [Model # SS-370-DCH]

Reasons This Model May Work for Your Application:

  1. Our standard singular air cleaner 70″ Wide Ductless Fume Hood is capable of up to 350 CFM, while the dual air cleaner model can reach up to 700 CFM.
  2. Many customers prefer this dual air cleaner option because two operators can utilize the hood at the same time (because of the unit’s width) and receive double the air volume.
  3. Two air cleaners also means double the filtration media.

Depending on the application you’re performing, a variety of filter media can be utilized. Options include:

  • HEPA Filtration- 99.97% efficient on particles 0.3 microns and larger
  • ASHRAE Filtration- 95% efficient on particles 0.5 microns and larger
  • ULPA Filtration – 99.9995% efficient on particles 0.12 microns and larger
  • Activated Carbon Filtration
  • Specialty-Blended Filter Media: Acid Gas, Mercury, Aldehydes, Ammonia
This high-flow, dual air cleaner model has been used for a variety of applications, including chemical fume control, soldering applications, pharmaceutical compounding containment, solvent and epoxy fume control, light dust removal, biological applications, and many more procedures that require the removal of fumes and/or particulate.
This filter housing on this fume hood (and most other Sentry Air Ductless Fume Hood models) is capable of holding multiple filters, so a combination of chemical and particulate filters can be used if the application emits both particles and chemical vapors.

This Ductless Fume Hood can also be customized in a variety of ways:
  • Increased air volume
  • Multiple-entry options
  • Size/Dimensions specifications
  • Custom cutouts
  • Multiple folding hinged lids
  • Custom material request
  • Blower mounting options
