Blowers and exhausters are both types of fans for air movement and ventilation, distinguished by their operational functions.
Blower:
- A blower propels air into a space or system, creating positive pressure.
- Its primary application is air supply to areas, conduits, heating units, or equipment.
- Blowers are designed to elevate both air pressure and volume in a regulated manner.
Exhauster:
- An exhauster extracts air, gases, or vapors from an area by generating negative pressure or suction.
- It is employed for ventilation purposes, such as expelling stale air, smoke, or hazardous fumes.
- Exhausters contribute to maintaining a clean and healthy atmosphere by removing undesirable airborne substances.
In essence, a blower introduces air, while an exhauster removes it.
