AeroTech's High Volume Limit Load Blower in SISW (Single Inlet Single Width) configuration is a direct-driven centrifugal blower where the heavy-duty impeller is mounted directly on the motor shaft, eliminating belts, pulleys, or couplings entirely. This design provides compact installation, low maintenance, and high mechanical efficiency. The blower housing is fabricated from high-quality steel with precision-welded construction, and the rigid, vibration-free design ensures stable long-term operation.
Impellers are available in backward-curved, forward-curved, or radial blade types as per application requirements, and all impellers are dynamically balanced for smooth, reliable performance. Delivers up to 2,50,000 CMH airflow at up to 1200 mm w. g.
static pressure. Handles temperatures up to 380°C with cooling disc arrangement. Available in MS, SS, Aluminium, and FRP with special coatings for corrosive or high-temperature environments.
Established in 1997, AEPPL has over 25 years of expertise serving power, petrochemicals, fertilizers, cement, mining, and automotive sectors. ISO 9001:2015 certified with rigorous dynamic balancing to international standards.

A Double Inlet Double Width (DIDW) blower should be chosen when you require massive volumetric airflow (CFM) in a clean-air environment with restricted installation space, such as an HVAC Air Handling Unit. For high-pressure or material handling, an SISW blower is required.
For highly abrasive airstreams containing cement clinker or boiler fly ash, impellers must be fabricated from abrasion-resistant alloys like Hardox 400/500 steel, or heavily coated with tungsten carbide, to prevent rapid blade erosion and fatal fan imbalance.
For extracting highly corrosive acids like hydrochloric or sulfuric acid, Fiberglass Reinforced Plastic (FRP) offers superior chemical resistance and lifecycle longevity compared to 316L Stainless Steel, which can still succumb to chloride pitting under extreme concentrations.
A V-Belt drive decouples the fan speed from the motor's synchronous RPM, allowing engineers to precisely tune the fan's performance curve by changing pulley ratios. It also thermally and mechanically isolates the motor from hot or vibrating fan casings.
Severe vibration is typically caused by severe impeller imbalance due to localized particulate buildup, abrasive wear on the blades, or bearing failure. Continuous vibration monitoring systems are recommended to detect these imbalances before they cause catastrophic shaft failure.
