Circulating unit (CU) to be installed below suspended ceiling or onto movable box 04/D
Circulating units are used to supply filtered air to a workplace and to protect the product from ambient contamination.
The design of the circulating unit, together with suitable regulation, provides uniform airflow at the outlet under the unit, with the required speed in the range of 0.3 ÷ 0.45 m.s-1 (when air density ς = 1.2 kg.m3).
The protective effect is enhanced by attaching flexible or fixed screens along the perimeter of the unit.
When installing the circulating unit in areas without a defined class of cleanliness or in an environment with increased dust generation, a pre-filter is mounted at the suction inlet of the unit.
