Square Inline Fan – size 24 in

The CHA24 is the highest-output unit in the square inline fan range, delivering 11,600 CFM through a 7.5 HP axial impeller. At this capacity, it is engineered specifically for continuous heavy-duty exhaust in large commercial kitchens, industrial processing lines, and factory floors where conventional fans fail to maintain adequate air change rates. The 24-inch duct connection handles the airflow volumes required by multi-hood kitchen installations or large production areas without requiring parallel fan configurations.

With 11,600 CFM of airflow and a 7.5 HP motor, the CHA24 addresses ventilation demands that mid-range inline fans cannot sustain. It is the right choice when the exhaust load consistently exceeds 8,000 CFM — such as large hotel kitchens serving multiple outlets simultaneously, industrial catering facilities with continuous high-temperature cooking, food processing plants with heavy grease and steam generation, or large-scale manufacturing environments with fume extraction requirements.

The galvanized steel housing (with stainless steel option) and fully welded structure are built to withstand the mechanical stress of continuous high-speed operation in harsh kitchen and industrial environments. The axial impeller design maintains high volumetric efficiency at 11,600 CFM while keeping noise levels lower than comparable centrifugal designs at the same output. Direct inline connection to standard circular ducting eliminates the need for adapters or transitions, reducing installation time and pressure drop across the duct run.

For installations requiring more than 11,600 CFM, two CHA24 units can be configured in parallel on a shared duct riser, effectively doubling capacity without increasing duct diameter beyond what the existing structure supports.
If your application requires between 8,000 and 11,000 CFM, review the CHA20 (8,700 CFM, 3 HP) as a lower-power alternative.
