KVD (direct driven) and KVB (belt driven) from sizes 7/7 to 12/12 are a range of single skin supply or extract box fans for inline application. These fans are designed for cost effective installations with low to medium pressure drop whilst keeping very good sound performances.

• KVD – Double inlet Direct Driven range with airfl ows from 700 to 7500 m3/h, IP 54 Class Motors single phase except 12-12-D6 three phase.

• KVB – Double inlet belt driven range with airfl ows from 700 to 13 000 m3/h IP 55 Class F motors.

Features & benefi tsRobust and quiet opera-tion thanks to the galvanized steel fan and motor support mounted on 4 anti-vibration rubber plots. Outlet connected to the casing through an 18 mm thick rubber joint acting as a fl exible seal. Reinforced bottom panel

giving the box fan more stability and mechanical resistance. Indoor and outdoor installation with the same standard unit. Easy to install with motor wired to the IP 55 connection box. KVB and KVD have a round inlet and square outlet. Effi cient double inlet galvanized steel forward curved impeller balanced stati-cally and dynamically. The KVB and KVD have a 3 year warranty. Airfl ows up to 50 000 m3/h are available upon request. Operates with air up to 50°C. Belt driven KVB range is available for three phase 60 Hz opera-tion.
