This article discusses the design of unidirectional airflow systems used to ventilate operating theatres and provide low concentrations of airborne micro-organisms during surgical operations.

The standard introduces the types of air diffusion, the UDAF that removes the airborne contamination by displacement, and the non-unidirectional flow (air mixing, non-UDF) that reduces airborne contamination by dilution.

Proper design and control prevents turbulence and stagnant air in the critical area. Once relevant parameters are established, it is crucial that airflow patterns be evaluated for turbulence or eddy currents that can act as a channel or reservoir for air contaminants (e.g., from an …

This article discusses the design of unidirectional airflow systems used to ventilate operating theatres and provide low concentrations of airborne micro-organisms during surgical operations.

Unidirectional Air Flow (UDAF) System: It creates a controlled airflow pattern where air moves in a single direction within a defined space. It maintains a clean environment over a filling line for pharmaceutical manufacturing by removing particles and contaminants.

The Uni-Directional AirFlow (UDAF) SteriPharm is an EU GMP Grade A (ISO14644-7:2004) aseptic environment in which various sterile tasks can be carried out. In this instance, the system was being used for sterility testing. While a unidirectional airflow is paramount for sterile production, a single pass turbulent flow system is also accepted (US

Uni-Directional Air Flow (UDAF) Booths and Canopies provide a localised clean air environment of ISO 5 (Grade ‘A’) over an aseptic process. They are usually positioned above machines and pieces of equipment within cleanrooms or secure environments.

Extract Technology was lately awarded a contract by one of the major pharma company in Russia for supply of its latest generation Uni-Directional AirFlow SteriPharm Isolator for sterility testing.
