Laminar Flow Cabins for Weighing and Sampling​

Laminar Flow Cabins for Weighing and Sampling​

These laminar flow cabins are used for production, weighing, sampling and packaging.
These laminar flow cabins consist of prefilters, fans, HEPA filters (H13/H14), lighting fixtures, electric and automatic control systems, PVC curtains, wheels or parts for hanging from ceiling. Also, day/night set back energy savings, alarm feature for motor failure and emergency shut down available on request with AC control systems.
Laminar Flow provides the highest levels of operator protection from potentially harmful airborne contaminants generated during manual powder handling operations such as weighing, sampling, charging and dispensing.
This unit provides product protection (Class ISO 5) from surrounding area contamination by creating a clean processing zone minimizing cross contamination risk from other products/processes.
Class ISO 5 according to ISO EN 14644-1 (Class l 00 according to Fed. Std. 209 E)
A negative pressure inside the unit prevents the escape of fine powders from the work area towards the external environment.
LF cabins consist of two stage pre-filters, fans, HEPA filters (H 13/H 14), lighting fixtures, electric and automatic control systems, PVC curtains, front legs or parts for hanging from ceiling.
Flexible PVC strip curtains and/or rigid walls increase the protection by separating the working area and external environment between each other.
Airflow is filtered by two stages of pre-filters. Also partially exhausted to create inside negative pressure after HEPA filtration.
Airflow recycled through the HEPA filters to generate the laminar flow.
