Specification text
Circular VAV terminal units made of flame-resistant plastic, for variable air volume systems and fume cupboards. Suitable for the control of extract air containing hazardous particles, as all components coming into contact with the airflow are made of plastic (no interior metal parts). Ready-to-commission unit which consists of the mechanical parts and the electronic control components (attachments). Each unit contains an averaging effective pressure sensor with bluff body or a nozzle for volume flow rate measurement, and a damper blade. Factory assembled control components (attachments) complete with wiring and tubing. Effective pressure sensor with 3 mm measuring holes, hence resistant to contamination. Position of the damper blade indicated externally at shaft extension. The damper blade is factory set to open position, which allows a ventilation airflow even without control. Meets the hygiene requirements of EN 16798, Part 3, of VDI 6022, Sheet 1, and of DIN 1946, Part 4.
