Ductless Fume Hoods: Why Go Ductless?

The Advantages of Purchasing a Ductless Fume Hood

There are numerous advantages to utilizing a Ductless Fume Hood as opposed to a conventional Ducted Fume Hood System. These benefits include mobility, cost efficiency, and environmental friendliness.


Sentry Air Systems Ductless Fume Hoods are highly convenient and portable. Because everything but the electrical plug is essentially internal, the hood simply has to be unplugged to be relocated. To move a ducted system would require a complete re-installation of ductwork, which may require the hiring of outside help to complete. Ductless Fume Hoods are up and running again in minutes.

Cost Efficiency & Minimal Maintenance

There are several reasons that Sentry Air Systems Ductless Fume Hoods are an economical choice:

  • Minimal Installation. When a Sentry Air unit arrives at its destination, it requires minimal installation. There are no costly installation fees.
  • Low Maintenance. The main and most important up-keep requirement for Ductless Fume Hoods is the replacement of the filter. Beyond filter changing and regular cleanings, these units are basically maintenance-free and don’t require outside assistance.
  • Heating & Cooling Systems. A large amount of money is spent on heating and cooling systems. Ducted systems typically take this paid-for heated or cooled air and channel it outside. Ductless Systems recirculate the air.
