Hoods Ductless, Captair, Purair, Streamline


The operation and installation cost of a ductless hood is substantially lower than that of a conventional hood. Once a ductless fume hood is installed, the only annual cost to the customer is the filter(s). A ductless hoods has no external connections beyond the power cord to be moved. Conventional hoods require a third party to move exhaust duct work and other connections before the hood may be relocated. Ductless hoods can be moved and operational in minutes where conventional hoods may be out of service for weeks

Ductless fume hoods provide excellent protection for the operator and other employees from toxic fumes and vapors that are generated during experiments in laboratories.

A fume hood is a device that is enclosed on five sides with the sixth side being accessible for operator and entrance of air. Ductless hoods, workstations and enclosures are not a total replacement for every exhaust system. However, ductless systems can be used for a variety of common applications being done in today's laboratory environment. A ductless system should never be used when chemistry produces unknown results or if known chemical volumes of evaporation is excessively high. With the advancement in chemistry technology, most reactions are completed at micro or nano levels. A ductless system, where low volumes of known chemical reactions are present, is practical and can provide a safe working environment.

Streamline Laboratory Products' vertical laminar flow cabinets are the ideal choice for those seeking laminar flow cabinets that offer consistent and reliable product protection at an economical price. Features include:

  • Class 100 (US Fed Std 209E) / ISO Class 5 product protection with 99.999% (at 0.3 microns) HEPA-filtered vertical laminar air
  • Mini-pleat HEPA filter with aluminium frames
  • All components of the cabinet are cleanroom compatible and do not particulate
  • Reinforced 304 grade stainless steel worktop with rounded edges in front for operator comfort
  • Electronic blower monitor with LED display on the front panel
  • Blower speed controller is also located inside the electrical panel
  • Energy-efficient external rotor motor design that ensures 360 degree
  • airflow distribution, and optimum airflow uniformity
  • Integrated filter/blower module
