Fume Hoods – Clean room equipment.
Key Features of Fume hoods for clean room
- All local ventilation systems (devices) are designed to three primary goals
- To protect the user from inhaling toxic fumes (fume hoods, glove boxes, biosafety cabinets)
- To protect the product or testing (experiment) (glove boxes and biological safety cabinets)
- To protect the atmosphere (recirculating fume hoods, biological safety cabinets, the exhaust airstream)

Description
Fume Hoods – Clean room equipment
A fume chamber or fume hood or fume cupboard is a type of local ventilation systems that is designed to limit coverage to toxic fumes, hazardous, dusts or vapors. The fume hood is two main types exist, PVC ducted and carbon filter recirculating (ductless). Other related types of local ventilation systems (devices) include: Laminar air flow, Biosafety cabinets, Clean benches, glove boxes and snorkel exhausts.
All local ventilation systems (devices) are designed to three primary goals:
- To protect the user from inhaling toxic fumes (Fume hoods, Glove boxes, Biosafety cabinets)
- To protect the product or testing (experiment) (glove boxes and biological safety cabinets)
- To protect the atmosphere (recirculating fume hoods, biological safety cabinets, the exhaust airstream)
Fume hoods naturally protect only the user, and are maximum commonly used in laboratories where noxious chemicals or hazardous are released research development, during testing, practicing and also used in industrial applications or other activities where noxious vapors or gases or hazardous or dusts are generated or released. Inspection of Fume Hoods should be inspected in accordance with the American Society of Engineers (ASHRAE 110) to certify proper control and ASHRAE 110 means quantifying containment performance

Specifications
Fume Hoods Specifications
- Ergonomic features, like taller sight lines, a crush-resistant sill airfoil, and a wire chase that keeps cords out of your way.
- Advanced ergonomic features, like an optional and innovative automatic sash control that automatically moves back to the correct working position while leaving your hands free.
- Safety features that are far above the industry standard – including higher-rated safety glass, thicker liner board, and consistent airflow delivery for the life of the hood.
- Innovative design that offers more usable space — ideal for a tall or bulky apparatus, material, or process.
- Quality construction for longer life, for all-welded steel frames to forged brass bodies on the remote service fixtures.

Applications
Airshower Applications
Cleanroom Applications:
The greatest source of particulate contamination in a cleanroom is the operator. Air showers are installed between change areas and the cleanroom. The air shower enhances
Cleanroom operating protocol by serving as a reminder to all operators that they are entering a controlled environment. Personnel therefore develop the habit of gowning up properly before entering the air shower.
Pharmaceutical and Lab Animal Research Applications:
- Air showers keep pharmaceutical production and lab animal breeding areas clean and also minimize egress of hazardous substancesand allergens from the controlled environment.
- Air is forced by the blower(s) throughULPA filter(s) which are >99.999% efficient against particles size between0.1 to 0.3 microns.
- Filtered air is ejected through nozzles at high velocities into the chamber.
- These turbulent air streams disperse particulate matter on all surfaces.
- Dispersed particulate matter migrates with the air stream towards the lowerareas in the air shower chamber.
- Air enters the blower supply plenum through pre-filter(s) installed at the base of thechamber.
- The air is continuously filtered and recirculated. The air shower is a self-contained device and does not exchangeair with the environment in which it is placed.
- A disposable pre-filter with 85% arrestance extends the life of the main filter.
- The air shower is constructed of electro galvanized steel sheets with an abrasion-resistant oven-baked powder coated finish.
- The air shower is constructed of SS 304 /SS 304L MAT finish.
- Air Shower is exclusively factory tested for safety and performance in accordance with international standards.
- In case of a power failure, automatically all doors are unlocked Optional parts
- Infrared sensor auto door
- ULPA filter
- Stainless steel or Galvanized
- No base plate, it is easy for truck to pass
- fluorescent lamp / Emergency switch
