FAQ's
Frequently Asked Questions
Why is a centrifugal blower used in a dust control system?
Centrifugal blower primarily moves air at high pressure to create suction, for overcoming the pressure drop across given Air pollution control equipment.
What's the difference between a drop-through and a blow-through rotary valve?
Drop-through valves discharge directly from hoppers; blow-through valves are integrated into pneumatic lines to introduce material into the air stream.
TNBi offers both types, engineered to match your conveying system’s flow, pressure, and material handling requirements.
Are TNBi spares compatible with non-TNBi systems?
Yes. TNBi spares, such as timers, bags, cages, and pulse valves, can be matched to most OEM setups. Retrofit kits are also available.
