Esco Airstream® Vertical Laminar Flow Cabinets offer proven protection for your samples and processes where operator protection is not required. Vertical laminar flow offers certain tangible advantages over horizontal flow cabinets (which may be the convention in some parts of the world), such as lower energy consumption (40% of conventional systems) levels through the use of exclusive motorized impeller technology and less airflow turbulence (especially when large objects are used in the work zone). In fact, the negative pressure filter mounting system employed on these models is widely recognised to be superior to that of conventional horizontal flow cabinets.

Product Highlights

ISO Class 4 air cleanliness within work zone as per ISO 14644.1 (equivalent to Class 10 as per US Federal Standard 209E, 10 times “cleaner” than the usual Class 100 classification on cabinets offered by the competition).
High-quality polyester pre-filter and main ULPA filter with a typical efficiency of 99.9997% at MPPS and 99.9998% at both 0.3 and 0.12 microns provide the best product protection in the world; typical main ULPA filter lifespan is more than 3 years depending on the usage of the cabinet.
Mini-pleat separatorless ULPA filter technology reduces energy consumption and delivers increased laminar airflow uniformity for better product and cross contamination protection.
Integral filter metal guard on both sides prevents accidental damage to ULPA filter; seamless filter gasket is permanently molded on the filter frame and will not deteriorate over time; aerosol (DOP/PAO) challenge test port included.

Cabinet Airflow Profile

Room air is taken in from the top of the cabinet through a disposable pre-filter with 85% arrestance; this serves to trap larger particles and increase the life of the main filter.
Air is forced evenly across the ULPA filter(s); the result is a stream of clean laminar air within the work zone of the cabinet; this dilutes and flushes all airborne contaminants from the interior.
A nominal filter face velocity of 0.45 m/s or 90 fpm ensures that there is a sufficient number of air changes within the enclosed area of the cabinet in order to maintain cleanliness.
The purified air travels across the working zone of the cabinet in a vertical, unidirectional stream and leaves the main work chamber across the entire open front of the cabinet and through Auto-Purge™ slots at the back wall of the workzone. Auto-Purge™ slots are designed to eliminate air turbulence and the possibility of dead- air corners in the workzone.
