Aura Vertical SD4 – the highest level of product protection, with operator protection

The Aura Vertical SD4 is a partially recirculating vertical laminar flow cabinet, designed for highly comfortable working conditions. The Aura SD4 laminar flow cabinet has unique design features that ensure class leading performance. The design of the Aura SD4 VLAF cabinet is almost identical to that typically found in microbiological safety cabinets and consequently provides a high level of protection to the operator, environment and product.

70% of the air is returned to the work area through the main H14 grade HEPA filter while 30% is exhausted into the environment through the H14 grade exhaust HEPA filter.
