  DC-5™ Air Saver
Dynamic Air's exclusive DC-5 Air Saver technology is the key to complete control of material through the entire conveying line
One of the secrets of a successful and highly efficient pneumatic conveying system, whether it is a high pressure dense phase system or a low pressure dilute phase system, is trying to achieve an optimum pressure balance. Many systems operate in what we call an unstable and/or unbalanced pressure condition. This means the conveying system can be using either too much compressed air or not enough compressed air, both of which are undesirable.
When excessive compressed air is used to convey a given material, the conveying velocity will be too high and the result can be material breakdown or excessive wear on the system. Also, the system will use excessive energy, and therefore maintenance becomes higher and reliability is reduced. When not enough compressed air is used, the convey rate may be too low and it’s even possible that conveying line plugging can occur.
It is also important to understand that every system must constantly fight friction, and that this friction is usually not evenly distributed throughout the conveying line. For instance, tubing bends are a major cause of friction in a pneumatic conveying system and they can easily be responsible for more than 50% of the total resistance of the pneumatic conveying system. The straight tubing in a system, however, has a much lower level of friction than a tubing bend.
Other friction factors which must be considered are components such as conveying line couplings, diverter valves, elevation changes, etc. Also, the shape, density and cohesiveness of each material to be conveyed create another variable which adds to the total friction factor, thus impeding the conveying process even further.
Therefore, the frictional resistance seen in the conveying line will vary considerably from system to system and throughout a given system, depending upon the components used plus the length of the conveying line and the conveying velocity. These varying and unbalanced frictional forces in a pneumatic conveying system, if not pressure balanced properly, can cause unstable and undesirable pressure and velocity conditions, resulting in poor performance and an unreliable and inefficient conveying system.
In order to create the optimum pressure balance in a pneumatic conveying system and to counteract the varying forces of friction, the compressed air must be properly and timely distributed for a smooth flow of material through the conveying line.
The pressure balance control must also be precise and instantaneous. If the pressure balance control reacts too slowly or overcompensates, the flow of material through the conveying line will be disrupted and the performance compromised.
To effectively counter balance all the friction factors normally inherent in a pneumatic conveying system, Dynamic Air has developed the DC-5 Air Saver technology which accurately controls and pressure balances the pneumatic conveying system.
The DC-5 Air Saver technology achieves the proper pressure balance because it automatically senses the conveying system conditions and reacts instantaneously and accurately without overcompensation. Thus material is conveyed through the conveying line in a smooth controlled manner and at the desired conveying velocity, to optimize the conveying process for higher performance and reliability.
The DC-5 Air Saver technology is adaptable to almost any type of Dynamic Air pneumatic conveying system regardless of the conveying pressure or vacuum.
