In Part 1 we looked at why sound is important, how we measure Sound Pressure and level, and how we measure Frequency, which describes the variation in sound pressure. In this second part we look at the remaining two important ways of measuring sound, Sound Sources and Sound Power.

Understanding the underlying physics of sound, where it is generated and attenuated, how we measure it, and the impact it has on us, is an important part of being able to design the right air movement systems and select the correct products.

Independent measurements carried out by Université Libre de Bruxelles (ULB) have indicated a doubling of the in-tunnel thrust, when conventional jet fans were fitted with MoJet® outlet silencers in the Montgomery Tunnel, Brussels.

Future-proof chilled-water solutions are now available for large projects from 380 kW upwards from FläktGroup.

Fläkt Woods, a FläktGroup company, solutions in action. Tunnel ventilation solutions are designed and installed for daily use but also as a precaution for devastating events which could occur... such as described in this article.

This article looks at factors to be considered when selecting the right fan to achieve the desired air flow volume. In particular, both fan and motor efficiency are explored.

This article explains the basic principle of air movement; how creating a pressure differential is the key to creating a flow of air; and how we can measure pressure – the first step in selecting the right fan to provide the desired air flow.

With the new HyFlex-Geko that is part of our innovative fan coil family we have created a new level of flexibility and performance. What was previously classified as great now defines a new high.

FläktGroup has extensive know-how and long experience of delivering the best possible balance between comfort and optimised energy consumption performance from our Air Handling Units.

We are very pleased to announce that, not only has our ECO TOP & SIDE casing achieved VDI 6022 Hygiene Standard but also has been approved for T2/TB2/L1(M)/D1(M).

Fläkt Woods UK (FläktGroup), together with Danfoss drives, are the first to announce: a fully certified en12101-3: 2015 packaged HT fan and VSD solution in the UK & Europe.
