Walk In Fume Hood

Walk in fume hood is a regarded as a great way to handle odors and toxic fumes from processing units and distillation assemblies. These floor standing fume hoods can feature services like air, gas, nitrogen or any other type of gas. Weiber mobile fume hoods are ducted or ductless as per choice, microprocessor based, advanced and CE marked equipments are designed for both laboratory and industrial application like:

• Extraction of fumes, aerosols and dusts from the internal workspace to prevent dangerous toxic concentrations from escaping into the laboratory
• For avoiding the creation of a dangerous, potentially explosive atmosphere in the internal workspace
• Protection against dangerous extrusive substances
• Protection against flying debris, compounds or particles from the internal workspace

Compatible Standards:

• ASHRAE-110-1995.
• CSA Z316.5-94.
• EN 14175
• CAN/CSA-22.2
• EN-61010-1
• IEC-61010-1

Special Features:

• Microprocessor based controls
• Welded superstructure for structural rigidity and design flexibility to contain large equipment and conveyances
• Three-piece baffle system with three adjustable dampers to regulate lighter- and heavier-than-air gases
• Airfoil around top and sides of sash opening, with electrical fixtures and plumbing controls mounted on bias surface
• Electrical switches and receptacles. Also explosion-proof lighting and fixtures available.
• Air velocity monitor/alarm
• Blowers � selected to match hood and ductwork configuration, corrosive or ignitable exhaust fume
• Removable exterior side panels.
• Double wall construction for ease of routing service piping.
• Lights are mounted above a sealed safety glass panel keeping corrosive fumes and hazardous vapors isolated.
• Safety equipment for operators, tested according to EN 14175

Operating Principle:

Fume-hoods draw air out of the rooms they are installed in. There needs to be an adequate volume of air available or the fume-hood will not be able to draw a sufficient volume of air to function properly. Protect you from fumes you are working with. The fan sucks in the air toward the duct inside of the fume hood and exhaust outside.

Testing Procedures of Containment

Fume hoods are specifically to decrease the loss of static pressure at a given baffle opening position. According to the standard procedures the average loss of static pressure at any given four points at ninety degree and 3 duct dia from the fume hood, that will not exceed 75 feet per minute at 0.25 inch, with full slash opening and face velocity of 100 feet per minute.
