CrystalAir supplies industrial-grade exhaust fans designed for continuous operation, high airflow capacity and long service life. If you are looking to purchase an exhaust fan for ventilation improvement, heat reduction or air extraction, this page outlines our available models and specifications.
For complete ducting design and airflow calculation services, please refer to our Industrial Exhaust System Malaysia page.
If your project requires multiple extraction points or duct routing, you may require a full Industrial Exhaust System Installation Service instead of a standalone fan.
See how CrystalAir’s industrial exhaust fan operates, including its automatic shutter mechanism, in this close-up demonstration video.
Our SMC Fiberglass Industrial Exhaust Fan is designed for high-volume ventilation in factories, warehouses and industrial buildings. Manufactured with a corrosion-resistant Sheet Moulding Compound (SMC) housing, it is suitable for applications requiring durable equipment, continuous air extraction and reliable airflow.
The direct-drive design connects the motor directly to the fan blades, eliminating the need for belt transmission and reducing routine belt maintenance. With high airflow capacity and an automatic shutter, this industrial exhaust fan is suitable for wall-mounted factory ventilation and selected rooftop applications with appropriate weather protection and installation arrangements.

CrystalAir Industrial Box Type Exhaust Fans are designed for high-volume air extraction in factories, warehouses, production areas and industrial workshops. They help remove accumulated heat and stagnant indoor air while supporting better ventilation across large working spaces.
We supply both belt-driven and direct-drive box type exhaust fans to suit different airflow requirements, installation conditions and maintenance preferences. These fans can be installed at suitable wall openings as part of a properly planned factory ventilation system. Correct fan sizing, placement and adequate replacement-air openings are essential for effective performance.

Our Rooftop Exhaust Fan is specially designed for installation on the rooftop of factories, warehouses and industrial buildings. It helps extract hot air, stale air and trapped heat from the highest point of the building, where heat naturally accumulates. Unlike conventional fiberglass exhaust fans that require an additional weather hood for roof installation, this rooftop model comes with a dedicated roof-mounted design, making it a cleaner, more practical and more weather-suitable solution for rooftop ventilation applications.
This fan is ideal for buildings where wall-mounted exhaust fans are not suitable, or where additional roof-level air extraction is required to improve overall airflow. When properly installed with roof support and flashing, the rooftop exhaust fan can help improve indoor air circulation, reduce heat build-up and create a more comfortable working environment for factories, warehouses, workshops and production areas.

CrystalAir Commercial Small Exhaust Fans are suitable for localized ventilation in smaller commercial and industrial spaces, including workshops, utility rooms, storage areas and selected factory sections.
These wall-mounted exhaust fans are available in different sizes and airflow capacities for applications that do not require large industrial extraction equipment. Selection should consider room volume, required air exchange, available installation space and the type of air being extracted.

CrystalAir supplies and installs industrial exhaust fans for factories and warehouses throughout Malaysia. The following projects demonstrate how different fan types and installation arrangements can be selected according to building layout and ventilation requirements.
For a metal fabrication factory with ground-floor and mezzanine areas, CrystalAir installed a combination of box type exhaust fans and rooftop exhaust fans to provide air extraction at different building levels.
This arrangement supports the removal of stagnant air from lower working areas and accumulated hot air from the upper roof space.
For a factory experiencing hot and stuffy indoor conditions, CrystalAir installed an active ventilation system using EX-325 and EX-200 box type industrial exhaust fans.
The fans were positioned across the building to support air exchange and reduce stagnant indoor air in different production areas.
Every factory has different ventilation requirements. Contact CrystalAir for advice on suitable industrial exhaust fan models, airflow requirements and installation arrangements.
Choosing the correct fan depends on:
Floor area (m²)
Ceiling height
Required air changes per hour (ACH)
Heat load level
Installation position (wall or roof discharge)
