Of all the machines in your company, did you bother to refer to their numerical designation? All industrial machines and appliances are classified using some numerical designations. This is based on the construction of the machine such as the material used to make the casing, shafts, blades, etc. For blowers, the numerical designation is based on the Air Movement and Control Association.
This equipment is available in a number of configurations. This can be based on the intended application or where they’ll mounted. This may include the duct blowers, roof ventilators, volume blowers, etc.
That is, the duct blowers can be designed with specifically for in-line mounting. This can be through the support braces or the flanges.
The industrial blower manufactures are very specific on these two aspects since they determine the ability of this machine to handle air efficiently. For example, quite a number of volume and pressure blowers are designed to handle air with an enclosure within the factory floor. Normally, they are designed such that they have a common mounting platform. That is, for both the electric motor and the blower. If possible, they should be mounted on vibration isolators.
In addition to the above factors, it is important to purchase only those products that comply with the factory standards. In fact, purchasing them from a reputable and ISO certified company can be a better deal.
