IP55 fan VRJ-4

high-temperatureradialextraction

Overview
Jet Fan System is used for controlled exhaust of smoke and harmful gases in case of fire in car parks and for daily ventilation. It limits smoke spread, provides smoke-free evacuation routes and improves safety. VENCO jet fans operate at low speed for daily removal of CO and vehicle emissions, reducing operating costs, and at high speed during fire events to confine and exhaust smoke rapidly. The fans increase firefighters' visibility, allowing approach up to 10 m and faster fire suppression, limiting damage to the car park.

Features

• Radial jet fans available in 50 N and 100 N thrust models reduce the number of units required in a system
