Tips for buying Laboratory Hood, Ductless

  1. Ductless laboratory hoods do not exhaust conditioned air to the outside, and therefore they are more energy efficient than exhaust hoods. However, the issue of safety of using ductless hoods with hazardous chemicals is still questionable.
  2. A laboratory that uses hazardous materials on a regular basis, may find the ductless hood to be of limited use.
  3. Because ductless laboratory hoods are used under a wide variety of conditions, they should be constructed of materials that provide safer and longer-lasting use. Ductless hoods should be rigid, nonflammable, and non-corrosive with a chemical-resistant and acid-resistant work surface. Ductwork and exhaust-fan materials must also be inert to any chemicals or substances used in the hood.
  4. The ductless laboratory hoods should come with an airflow monitor with an alarm to measure the face velocity and to alert employees when operation is out of range.
  5. An alarm should be provided by the exhaust blower/fan to indicate below-normal operation.
  6. An adjustable sash is recommended to provide access to the inside of the ductless laboratory hood without the need to completely open the sash. This may allow harmful fumes to escape the ductless hood. The sash should be made of shatterproof material to protect against small explosions that may occur during handling of dangerous substances inside the ductless hood.
  7. Among the most common pieces of equipment in any laboratory are chemical fume hoods. Facilities should look into various important factors specific to each individual laboratory.
  8. When installing new air handling or local ventilation equipment, such as fume hoods, facilities should assess ventilation quality and quantity to ensure that the airflow remains uniform and non-turbulent.
  9. Facilities should carry out routine ductless laboratory hood monitoring at least quarterly and should include airflow patterns and face velocity, as well as maintenance of fans, ducts, and grilles.
  10. Before the purchase of auxiliary-air fume hoods, facilities should carry out an energy audit to determine if the cost of installing untreated air-supply systems justifies the savings from running less conditioned air through the hoods.
