How to Install Different Types of Exhaust Fans?

According to the installation position of the exhaust fan, it can be divided into wall-mounted, window-mounted, and ceiling-mounted types. The installation methods of different types of exhaust fans also vary slightly.

Common Types of Exhaust Fans

Wall-mounted Exhaust Fan

Wall-mounted exhaust fans are directly installed on the wall hole, with the 6-inch wall extractor fan being more common. These exhaust fans are generally small in size. Due to their narrow cross-section, their ventilation strength is weaker, making them suitable for relatively small and enclosed spaces.

When installing a 6-inch wall extractor fan, first measure the exact size of the exhaust fan’s outline and the screw hole installation position, then use a steel chisel or a portable impact drill to drill the installation hole on the wall. Place wooden blocks (or wooden cushions) inside the hole and embed with mortar. Once the mortar hardens, the 6-inch wall extractor fan can be installed. Since the installation position of the 6-inch wall extractor fan is relatively low, it must be securely fixed to avoid loosening during use. Waterproof measures should also be taken during installation to ensure the lifespan of the exhaust fan.

Window-mounted Exhaust Fan

Window-mounted exhaust fans are installed on windows, which eliminates the need to drill holes in walls and saves on ventilation ducts. However, window-mounted exhaust fans take up window space, blocking some light. During installation, first remove a piece of glass, measure the exhaust fan size, drill holes in the window frame using an electric drill, and thread screws into place. If the window frame is larger than the exhaust fan, prepare a piece of galvanized sheet to fix the exhaust fan, with the sheet surface painted to prevent rust.

Ceiling-mounted Exhaust Fan

Ceiling-mounted exhaust fans are installed on the ceiling and are more aesthetically pleasing, usually requiring suitable lengths of ventilation ducts. For aluminum buckle plate ceilings, metal fasteners matching the ceiling keels are generally equipped, making installation convenient. For wood keel ceilings, connect the ventilation ducts first, and then fix the exhaust fan panel with wood screws.

Exhaust Fan Installation Instructions

Pre-installation Inspection

Before installation, carefully check whether the exhaust fan product is intact, whether the fasteners and bolts are loose, and whether the impeller has collided with the fan cover, etc. Check for any damage during transportation, particularly for small equipment like the 6-inch wall extractor fan. When choosing the exhaust outlet location, avoid major obstacles within a three-meter radius of the outlet.

Installation Points

The exhaust fan should be installed level, and the installation position should be stable and not tilted. After installation, check the surrounding seals, and if necessary, use glass glue to seal gaps to prevent air leakage.

Installation Acceptance

After installation, check whether any tools or debris are left inside the fan. Manually rotate the fan blades to ensure smooth movement without obstructions. Only if no anomalies are found can the fan be test run. If vibrations or abnormal motor sounds occur during operation, stop the fan immediately for inspection and repair. For the 6-inch wall extractor fan, due to its wall-mounted position, ensure it is securely fixed and properly sealed to ensure safety and effectiveness.
