Square Inline Fan – size 8 in

The CHA08 moves 2,270 CFM through an 8-inch inline body using a 0.75 HP motor. It is designed for enclosed spaces where a low-noise, low-power ventilation unit must run continuously — including residential and commercial bathroom exhaust, server room cooling assist, small retail storage areas, wine cellars, and under-floor or inter-floor ventilation voids where larger units cannot be physically accommodated.

Main Features With RCD Series

• Full mold, full welded structure, galvanized sheet or stainless steel housing
• Technology axial impeller with higher efficiency and lower noise
• Compact design, easy to install
• It is designed for direct connection in line with standard diameter circular ducting
• Chinese Energy Saving label
• ISO9001:2000 controllable standard
• CFM = 2270
• HP = 0.75

At 0.75 HP, the CHA08 is the most energy-efficient unit in the CHA lineup capable of sustaining 2,270 CFM on a continuous basis. This low power draw makes it practical for installations where the fan operates 16 to 24 hours per day — such as server room hot-aisle exhaust, parking level CO extraction on small basement levels, or continuous toilet exhaust systems in apartment buildings where energy consumption across multiple units is a significant operational consideration.

The 8-inch duct size positions the CHA08 in the standard range used by residential and light commercial HVAC contractors, which means installation, spares, and duct components are readily available without special ordering. The compact inline body can be installed horizontally or vertically within ceiling voids, riser shafts, or service corridors as narrow as 300 mm, provided the duct runs are straight for at least 1.5 duct diameters on each side of the unit.

For applications that currently use 2,270 CFM but anticipate future growth — such as a retail unit that may expand its kitchen operations — the CHA10 (3,600 CFM, 1.5 HP) offers a direct upgrade path without changing the duct layout beyond increasing from 8-inch to 10-inch connections. The CHA05 (1,750 CFM, 0.25 HP) is available for very small or highly restricted ventilation requirements where the CHA08 would be oversized.
