Laminar Flow Powder Hoods provide a single direction of air flow through the hood. As opposed to turbulent flow that doesn’t have an orderly flow. Laminar flow powder hoods provide a faster and more efficient elimination of powder hazardous fumes.
Laminar Flow Powder Hoods
Flow Sciences’ Contained Vented Enclosure (CVE) / Laminar Flow Powder Hood series comes with a built-in exhaust system that is also compatible with house systems to suit various benchtop / scale-up operations and nanotechnology applications. CVE enclosures use airfoils and plenums to create a laminar airflow across the work surface, reducing eddies and turbulence in order to ensure reproducibility, accuracy and containment. Each unit comes with a face velocity alarm; acrylic walls for added visibility; and a chemically resistant, dished phenolic base to maintain spills and protect the work surface from harmful chemicals.
Exhaust Port
6” Thimble connects to house system or can be recirculated back into the lab
Face Velocity Alarm
FS1650 face velocity alarm alerts the operator when airflow is compromised
Bag-In / Bag-out HEPA
HEPA change out system that allows for safe removal and replacement of the primary 4” HEPA filter
LED Light
LED light to illuminate the work surface
Dished Base
Dished phenolic base captures accidental liquid and powder spills
Top and Rear Plenums
Top and rear plenums are used to direct airflow and maintain containment at the face opening. These also prevent particles from possibly falling back onto the work surface if the fan is turned off.
Front Lift Doors
Hinged front doors that lift for easy loading and unloading of equipment.
Airfoils
Airfoils staged around the perimeter of the face opening stabilize the airflow, improve laminar airflow and improve containment along the leading edge.
Single HEPA Filter – Bag Out Series
Flow Sciences’ Single HEPA Series Contained Vented Enclosures are designed for maximum containment with the use of airfoils and plenums, creating a laminar airflow across the work surface, which reduces eddies and turbulence.
The ETA Series features a front door lift that allows for easy loading and unloading of equipment. The single 4” thick HEPA filter and the fan is ideal for bench top/scale up and nanotechnology applications and has been proven by an independent test organization to contain loss based on process and quality.
The top-mounted exhaust system can recirculate air into the lab or send it directly to the house exhaust without transferring vibration from the fan unit to the work surface.
As an additional safety measure, FSI’s Contained Vented Enclosures feature a face velocity alarm that visually and audibly alerts the operator when airflow is compromised. These features allow for reproducibility and accuracy of weighing.
In case of an accident, the dished phenolic base is chemically resistant and designed to contain spills. The ETA Series is available in 3’ or 4’ standard width units and features LED lights and waste ports to safely transfer contaminants from the enclosure.
Dual HEPA Filters – Bag In / Bag Out Series
Flow Sciences’ Dual HEPA BIBO Series of Contained Vented Enclosures are designed to prevent loss of containment with the use of airfoils and plenums, creating a laminar airflow across the work surface, which reduces eddies and turbulence. The ETA Series features a front door lift that allows for easy loading and unloading of equipment.
The single 4” thick HEPA filter with fan is ideal for benchtop/ scale up and nanotechnology applications and has been proven by an independent test organization to contain loss based on process and quality. FSI’s state-of-the-art BIBO feature allows the operator to safely remove and replace the main filter while maintaining maximum containment from toxic fumes and particles.
