Preparing airflow intelligence
Calibrating industrial-grade components and rendering the next section.
AeroTech's High Volume Limit Load Blower in DIDW (Double Inlet Double Width) configuration features air entry from both sides of the blower, providing higher airflow in a compact size. The backward curved impellers are fabricated from high-grade steel, dynamically balanced for smooth vibration-free operation. The rigid welded construction from heavy-gauge steel with scroll-type casing ensures efficient air guidance.
The non-overloading characteristic of backward curved impellers inherently limits absorbed power, preventing motor overloading — a critical safety feature for large industrial systems. Available in direct drive or belt-driven configuration. Anti-corrosive powder coating or epoxy paint for enhanced durability.
Heavy-duty ball bearings and precision-machined shaft for continuous duty. Delivers up to 2,50,000 CMH at above 1200 mm w. g.
static pressure, handling temperatures up to 380°C with cooling disc. Available in MS, SS, Aluminium, and FRP. Widely used in HVAC air handling units, central AC plants, clean rooms and laboratories, industrial ventilation in factories and workshops, commercial spaces including malls, theatres, hotels, hospitals, and office complexes, and power plants and refineries for combustion air supply.
