Esco cleanroom products include fan filter units, air showers, softwall cleanrooms, pass through boxes/transfer hatches, powder containment, downflow booths and garment storage cabinets.
Backed by decades of experience, Esco cleanroom products offer state of the art designs compliant with the latest international standards. The firm strives to offer the most efficient, cost effective and highest quality products in today’s market and this strategy is adopted in the development of all Esco products, from microbiological safety cabinets, fume cupboards and CO2 incubators to ultra low temperature freezers.
Significant investment in research and development helps Esco in its quest to provide the highest quality products and many experiments are performed to validate the quality and capacity of these products.
The greatest source of particulate contamination in a cleanroom is the operator. Air showers are installed between changing areas and the cleanroom. The air shower enhances cleanroom operating protocol by serving as a reminder to all operators that they are entering a controlled environment. Personnel therefore develop the habit of gowning up properly before entering the air shower.
Air showers are self-contained chambers installed at the entrance of cleanrooms and other controlled environments. They do not exchange air in the environment in which they are placed, allowing them to be positioned in new or existing cleanrooms without upsetting current airflow regimes. They minimise particulate matter entering or exiting the clean space. Personnel and materials entering or exiting the controlled environment are “scrubbed” by high velocity HEPA-filtered air jets with velocities of 20–22m/s (4,000–4,300fpm). Contaminated air is then drawn through the base within the unit, filtered and recirculated.
Esco is a leader in air showers for demanding applications in the microelectronics, semiconductors, pharmaceutical, spray painting, lab animal research and food markets. The current Esco air shower is a third-generation product and features field-programmable microprocessor control that offers the maximum application flexibility of any unit on the market.
In regards to effectiveness of animal allergen removal, the recommended synthetic clothing material for minimising the transfer of allergens from animal facilities is polyester. When cleaning polyester lab coats, the Jetstream Air Shower (JAS) managed effectively to remove 95.4% of the allergens after 60 seconds of air showering.
