- Provide a high degree of protection
- Demanded by medical, pharmaceutical and scientific fields.
- Do not protect personnel from aerosols of hazardous materials that may be handled in the cabinet
Description
Air in the HWS Horizontal Laminar Flow Cabinet is passed through the work zone in a smooth, horizontal direction, the blower fan and mounting position are designed to maximize airflow. The deeper rear plenum ensures unobstructed airflow to the HEPA filter face. As a result, the cabinet is quieter with reduced vibration and longer service life for the HEPA filter.
Personnel Protection
Horizontal Laminar Flow Cabinet cabinets provide protection for products or experiments, however they do not protect personnel from aerosols of hazardous materials that may be handled in the cabinet.
For applications where personnel and environmental protection is required, Other Cabinets such as the Class I or Class II biological safety cabinets, or cytotoxic drug safety cabinets (as applicable) should be considered.
Applications
HWS (Horizontal-flow) Laminar Flow Series cabinets are designed to provide a high degree of protection for process products and apparatus in laboratory and production facilities. Critical Applications in industries such as Medical, Pharmaceutical, Scientific and Electronic Fields Demand an ultra-clean work environment that 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 and
- Sterility testing.
HWS Series Laminar Flow cabinets are intended for work with non-hazardous materials in such applications.
Australian Standards
The HWS Horizontal Laminar Flow Cabinet is designed and compliant to Australian Standard: AS2252.6 with Air Cleanliness compliant with ISO class 5 (class 100) AS ISO 14644.1.
AES Environmental maintains an ISO 9001:2015 quality management system to ensure process and product conformance.
- Hourmeter
- Manometer
- Service taps for air, gas and vacuum
- Extra quiet operation
- Floor stand (fixed height)
- Floor stand (electric height – adjustable)
HWS Series cabinets are factory tested by a NATA-Accredited laboratory. Additional testing is recommended as follows:
- On site prior to use
- After maintenance
- After filter replacement
- After re-location
- At least annually
- In special circumstances, e.g. if faulty operation is suspected.

Cabinet
The housing is constructed of locally sourced steel and consists of a high quality powdercoated finish to provide a suitably solvent, alkali and acid resistant laboratory grade coating. The work area is fully constructed from stainless steel, with inward folds to avoid sharp edges. A removable, washable metal screen protects the HEPA filter from 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 quiet operation and low vibration level.
HEPA Filters
Clyde-Apac® HEPA filters, are manufactured to AS 4260. Each filter is individually tested to be leak-free in accordance with AS 1807.6. A manufacturer endorsed test label fitted with an extract of the test report is affixed to each filter. A prefilter extends the life of the exhaust HEPA filter and protects it from the mechanical damage during cleaning of the work zone.
Pre-Filters
An easily-accessed, washable pre-filter 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 pre-filter service.
Electrical
A low voltage touch control panel is located on the front of the cabinet. Glare-free lamps provide a minimum lighting intensity of min 650 lux at the work floor.
