VERTICAL LAMINAR AIRFLOW CABINETS

How it Functions :
  • The room air is taken through the top of the cabinet through the pre filter, which traps larger size particles and increase the life of main HEPA filter.
  • Air is forced evenly through the HEPA filter, resulting the stream of unidirectional clean air within the work zone of the cabinet
  • A nominal filter face velocity of 0.45m/s or 90 fpm (+/- 10%) ensures the sufficient number of air changes within the enclosed area of the cabinet in order to maintain cleanliness.
  • The filtered air travels across the internal work zone of the cabinet in unidirectional vertical stream and leaves the main work chamber across the entire open front of the cabinet.
HORIZONTAL LAMINAR AIRFLOW CABINETS

How it works :

  • The room air is taken through the bottom of the cabinet through the pre filter, which traps larger size particles and increase the life of main HEPA filter.
  • Air is forced evenly through the HEPA filter, resulting the stream of unidirectional clean air within the work zone of the cabinet.
  • A nominal filter face velocity of 0.45m/s or 90 fpm (+/- 10%) ensures the sufficient number of air changes within the work area of the cabinet in order to maintain cleanliness.

BIOLOGICAL SAFETY CABINETS CLASS III
The Class III cabinet is defined as a totally enclosed ventilated cabinet of gas-tight construction and is suitable for handling agents assigned to Biological safety levels 1, 2, 3 and 4.

How it works:

  • Two fans regulate the Airflow in the cabinet (refer the diagram). In case of failure of the exhaust fan (F2), the supply fan (F1) does not function, since they are interlinked. However, the exhaust fan will continue to run in case of failure of the supply fan. This ensures total protection to the operator and the environment.
  • The room air is taken through a pre filter located on top of the cabinet, which traps large size particles and increase the life of main supply HEPA filter.
  • Close to the work surface, the down flow air stream 'splits' and enters the exhaust plenum from the front and rear perforations provided in the work area, providing a uniform down draft over the entire work area.
  • The downflow of the cabinet enters the exhaust plenum below the worktable, where it passes through two HEPA filters in series, one mounted below the worktable and the other above the main chamber.
  • The air from the exhaust plenum is double HEPA filtered and exhausted directly back to the lab without recirculation. Optionally, an exhaust collar can be provided for connecting to a dedicated ductwork system, to pass the air to the external environment.
  • The material of construction is industrial-grade galvanized steel with abrasion resistant white epoxy powder coated finish.
Features & Benefits:

  • Operations in the cabinet are conducted through attached rubber gloves.
  • Designed for an absolute level of containment, they are frequently used for work involving the hazardous bacteria, virus and microorganisms.
  • Exhaust air is double HEPA filtered through superior quality HEPA filters (9.997% down to 0.3?), thus ensuring complete product, operator and environmental protection from airborne biological hazards; a pre filter also extends the life main filter.
  • Integrated pass-through with interlocking doors at one side of main chamber allows materials to be transferred into the cabinet without the risk of environmental contamination.
  • Durable and easy to clean stainless steel work top will never rust or cause contamination.
  • Permanently lubricated direct drive centrifugal blower(s) reduces operating costs.
  • Two Magnahelic gauges are mounted on top of the equipment for monitoring negative pressure in the work zone during usage and the pressure built up on the HEPA filters
Microprocessor is optional at additional cost:

Microprocessor Functions:

  • Audible and visual alarm for lower exhaust.
  • Built in 24 hr clock and experiment timer.
  • An admin PIN can be set to restrict unauthorized access to all menu functions.
  • Built in solid-state variable speed controller (adjustable from zero to maximum setting).
  • Excellent illumination in the work zone.
  • Cabinet airflow velocity is displayed constantly on the LCD displays.
  • U V hour meter for monitoring total usage time of UV lamp.
  • Superior electrical safety for the operator since all cabinets are factory tested after production at manufacturing site.
