Type "VP" Voidpack Range Air Handling Units  
The VP range of air handling units are primarily designed for the small size installation where access and low cost are of prime consideration. They are specifically adaptable for ceiling voids and below floor installations.

Units are of pentapost framework construction with double skin insulated panels offering good thermal properties and maximum acoustic power loss through casings. Special purpose built designs are available on request.

Capacity

VP range air handling units are available as standard in four different sizes, VP1 to VP4, covering capacities from 0.10m³/s to 2.00m³/s.

Selection

Selection is usually dependent on coil velocity. Two duties are listed for each unit, 2.40m/s for cooling applications and 3.60m/s for general ventilation applications.

Arrangements

The main body of the unit is generally supplied in one section, although as an option it can be supplied in two sections for ease of access.
 Six standard arrangements are listed, below, although many more can be incorporated. The sequence of components may also be varied to suit specific applications.
