Deliver Ventilation Scope with Fewer Units and Lower Electrical Load
AN INNOVATIVE Tunnel ventilation system
Major infrastructure projects must demonstrate sustainability and value for money while delivering the required performance. That is why we have developed the MoJet®, an innovative tunnel ventilation system which has been installed worldwide.
The innovative design results in markedly improved energy efficiency and fewer or smaller jet fans being required to provide the same degree of ventilation, as verified by independent measurements in full-scale tunnels.
MoJets® do not encroach upon the traffic envelope, and can be installed very close to tunnel walls and soffits, reducing space requirements and construction costs. To calculate the performance of the MoJet® compared to conventional jet fans, please use our installation factor calculator. To estimate the reduction in your procurement and annual operating costs, please download our estimator.

WHY USE MOJET? Benefits of using the MoJet®
Reduced number of jet fans
The innovative design results in markedly improved energy efficiency and fewer or smaller jet fans being required to provide the same degree of ventilation

Reduced power consumption
lower costs for energy and installed power, as well as a lower carbon footprint.

Reduced cabling costs
MoJets® can be installed much closer together than conventional jetfans.
