Esco Airstream Horizontal Laminar Flow Clean Bench offers proven protection for your samples and processes. With over thousands of units in use worldwide, this model offers a sensible balance of quality, performance features and cost-effectiveness. Like all Esco clean benches this model features many key innovations for which Esco is recognized for: mini-pleat separatorless ULPA filter technology, the best product protection in the world, external rotor motors, superior filter mechanical construction.

Features

·      ULPA filters (per IEST-RP-CC-001.3) tested to a typical efficiency of >99.999% for 0.1 to 0.3 micron particles are better than HEPA filters. ULPA filters last as long as conventional HEPA filters and have similar replacement costs.

·      All Esco laminar flow clean benches provide ISO Class 3 air cleanliness within the work zone as per ISO 14644.1, significantly cleaner than the usual Class 5 classification on clean benches offered by the competition.

·      The intelligent blower system maintains airflow as the filter becomes loaded, ensuring optimum efficiency and product protection.

·      An additional disposable pre-filter traps large particles in the inflow air prior to reaching the main filter, protecting against damage and prolonging filter life.

·      All Esco products are manufactured for the most demanding laboratory applications. All components are designed for maximum chemical resistance and enhanced durability for a long service life. The main body of the clean bench is constructed of industrialgrade electro-galvanized steel.

·      One piece formed stainless steel work surface with a curved front edge is designed for maximum operator comfort.

·      Built-in warm white, electronically ballasted, 5000k lighting provides excellent illumination of the work zone and reduces operator fatigue. The reliable lighting system is zero-flicker and instant start.

·      Esco Laminar Flow Clean Benches have been tested for cross-contamination and product protection using microbiological test methods specified in EN12469.

·      Each clean bench is individually factory tested for safety and performance in accordance with international standards.

·      Most of electrical components are UL listed or UL recognized, ensuring superior electrical safety for the operator.

·      Esco ISOCIDE antimicrobial coating on all painted surfaces.

Airflow

·      Room air is taken in from the top of the clean bench through a disposable pre-fi lter 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 clean bench; this dilutes and fl ushes all airborne contaminants from the interior.

·      A nominal filter face velocity of 0.45 m/s or 90 fpm ensures that there is a suffi cient number of air changes within the enclosed area of the clean bench in order to maintain cleanliness.

·      The purified air travels across the internal work zone of the clean bench in a horizontal, unidirectional stream and leaves the main work chamber across the entire open front of the clean bench.
