AirMaster - SMV

Consultant: The Keenan Consultancy

Client: University of Edinburgh

The Project

Refurbishment of a studio and a media room at the University of Edinburgh’s student radio station has included installation of SAV Systems’ AirMaster mechanical ventilation with heat recovery units.

The student radio station was launched in October 1992 and is one of the longest running student broadcasting services in the UK. It was recently re-branded as an internet radio station called and its facilities were refurbished.

The Challenge 

As both the studio and the media room are windowless there was a need for mechanical ventilation and AirMaster units were specified by The Keenan Consultancy for their ability to meet strict performance criteria. These included a requirement for very low noise levels during broadcasting, as well as demand controlled ventilation to align fan operation to variable occupancy levels, thereby optimising energy efficiency.

The Solution

AirMaster units are inherently quiet (35dBA at 1m) and become even quieter by reducing fan speed (e.g. 30dBA at 1m at 80% of full throughput). In the case of, the fans were set to modulate between 40% and 100% of full throughput, meaning that operation below 80% can be expected regularly.

In addition, the units can attenuate external noise by at least 49dB to minimise intrusion by external noise.
