While Gravity Ventilation can be cost effectively and successfully applied to the majority of industrial and a significant number of commercial applications, there are occasions where ventilation is still required, but because of insufficient temperature differential being generated in the building, or because of the building configuration etc, gravity ventilation may not always be able to provide the guaranteed level of air flow required for particular applications.

In these instances the most desirable option could be to either provide a full mechanical ventilation system, or at the least, supplement the gravity system with some mechanical vents.

As part of Robertson's 'One Stop Ventilation Shop' we are able to provide the equipment necessary to meet individual project requirements.

In addition to the Robertson range of Gravity Ventilation products we can therefore provide:

• Axial Flow Fans
• Silencers
• Roof Exhaust Units
• Roof Inflow Units
• Mixed Flow Fans
• Wall Fan Units

As well as having the capability to provide the above equipment, Robertson are able to design, manufacture, supply and install complete mechanical ventilation systems for such specialised applications as Power Generation plants, Materials Handling applications, Environmentally Sensitive Industrial Processing facilities, etc.
