Descriptions:

• HWS Series cabinets are self-contained Class 3.5 horizontal laminar flow work stations designed for installation on standard laboratory benches, or on optional floor stands. Cabinets are produced with work zone width of 90cm, 120cm or 180cm, with the option of 60cm or 75cm work zone height.
• Each cabinet is factory-tested and certified by a NATA-registered laboratory to establish compliance with the performance requirements of AS1386, Part 5.
• Vertical Flow Cabinets : VWS Series cabinets may be preferred for applications where the work process is optimally presented to vertical airflow.
• Operation : Horizontal laminar flow in the work zone creates a biologically-clean, particle-free work environment.
• A direct-drive fan draws in ambient air through a prefilter on the top of the cabinet and supplies it to the work zone through a HEPA filter. The average air velocity in the work zone is maintained between 0.45 and 0.5 m/s, with all velocity readings within 20% of their average.
• Air cleanliness within the work zone is better than Class 3.5 (Class 100). To enhance work zone air cleanliness, it is recommended that cabinets are installed in cleanrooms which provide a secondary barrier.

Applications:

HWS Series cabinets are designed to provide a high degree of protection for process products and apparatus in laboratory and production facilities. Many critical applications in the medical, pharmaceutical, scientific and electronics fields demand an ultra-clean work environment which is free from biological and particulate contamination.

Typical applications include:

• Aseptic dispensing
• Assembly of electronics and optics components
• Cell culturing
• Media pouring
• Preparation of medical devices/equipment
• Sterility testing

Constructions:

• Cabinet
  Constructed in electro-galvanised steel, etch primed and finished in a special baked enamel that has been developed for laboratory equipment. The work zone is constructed in Grade 304 stainless steel. The stainless steel work surface incorporates a lip to prevent liquid spills from contacting the HEPA filter. A removable, washable metal screen protects the HEPA filter form mechanical damage.
• Fans
  A direct-drive fan is regulated by a speed controller to enable airflow to be maintained through filter life. Fans and filter plenums are designed to provide ultra-quiet operation and low vibration level.
• HEPA Filters
  Clyde-Apac HEPA filters, are manufactured to the most exacting standards for critical applications. Each filter is individually certified to achieve an arrestance efficiency of not less than 99.995% to the stringent BS3928 Sodium Flame test.
• All testing is conducted in a NATA-registered factory laboratory and a NATA-endorsed test label, being an extract of the test report, is affixed to each filter.
• Prefilters
  An easily-accessed, washable prefilter arrests not less than 90% of particles 5 micron and larger, thus prolonging HEPA filter life. A warning light in the control panel signals the need for Prefilter service.
