Ravenscroft specialises in providing low velocity displacement ventilation solutions to commercial and manufacturing premises.

Displacement ventilation is the perfect solution for lobbies, theatres and large public spaces with high ceilings and large air volume requirements. Thermal displacement ventilation is based on cool air supplied at low level and due to the natural buoyancy of warm air, draws fresh air into the occupied zone. This results in the occupant constantly enjoying fresh air in pleasant temperatures.


Halton low velocity displacement ventilation creates a comfortable, draft free atmosphere while guaranteeing adequate fresh air for the occupants. Because incoming air is released at such low velocities, displacement ventilation is practically silent, making it an ideal solution for areas where acoustics are essential.

Flexible Designs

Displacement ventilation can be supplied from various diffuser terminals, including false columns, free standing drums, under floor diffusers and units built into the walls. Displacement ventilation diffusers are easy to adapt into interior features by disguising them behind architectural facades.

Several international studies have found that indoor air quality in schools remains poor. This causes an increase in symptoms and illness, shortens attention span, while good air quality can enhance children’s concentration and also teachers’ productivity. The most common indoor climate problems are inadequate ventilation and thermal comfort.

Halton low velocity displacement ventilation diffusers can be concealed in numerous ways behind architectural facades.

This allows the diffusers to blend into the design or to become design features themselves.

Facades can be made of a multitude of materials, including wood and metal.
