High-temperature fan VRJ

IP55radialextraction

Overview
Jet fans are used to control and extract smoke and harmful gases in car parks, and for daily ventilation. VENCO VRJ radial jet fans operate at lower speeds to remove CO and vehicle emissions during normal operation and at higher speeds to limit smoke spread in fire situations, enabling faster evacuation and safer access for emergency services. Tested to EN 12101-3, these units help maintain visibility for firefighters up to approximately 10 m.

Features

• Available in 50 N and 100 N thrust models to reduce the number of units required
