DIY Guide: How to Install a Ventilation Fan in Difficult Frames

1. Measure & Adjust the Frame

If your wall or window frame is smaller or larger than the fan size, you can create a custom mounting board using plywood or PVC sheet. Cut it to fit the opening, then attach the fan securely.

2. Wall-Mounted or Window-Mounted Options

• Wall-mounted exhaust fans (kipas ekzos dinding) are best for kitchens and bathrooms.

• Window-mounted fans are perfect when there’s no external wall space.

3. Using Ducts for Airflow Direction

In tight spaces, you can add an HVAC duct or vent pipe to guide airflow outside. This is useful in small rooms or teres rumah where direct mounting isn’t possible.

4. Silent & Low-Noise Setup

Look for quiet extractor fans or brands like Khind that are known for low noise performance. This makes them suitable for bilik tidur (bedrooms).

5. Temporary or Cheap DIY Fixes

If you cannot cut the wall, use a portable extractor fan setup. Some mini ventilation fans can be mounted with brackets or simply fixed near a window vent.
