FOCUS ON EC FAN ONLY
In industrial environments, ventilation and cooling systems are exposed to dust, moisture, and challenging operating conditions. Standard fans often fail to provide long-term reliability under these circumstances, leading to costly downtime and maintenance. This is where IP55 fans become critical.
IP55-rated centrifugal (IP55 Backward Curved Centrifugal Fan, IP55 Forward Curved Centrifugal Fan) fan and IP55 axial fans combine robust design with reliable protection against dust and water, making them ideal for industries such as refrigeration, data centers, mechanical equipment, and outdoor HVAC systems.
In this article, we explain what IP55 protection means, the benefits of IP55 centrifugal and axial fans, and the environments where they deliver maximum performance.
The IP (Ingress Protection) rating is an international standard (IEC 60529) that classifies the degree of protection offered by electrical enclosures against dust and liquids.
First digit “5” → Dust-protected. Limited ingress of dust is permitted but not enough to interfere with the fan’s safe operation.
Second digit “5” → Protected against low-pressure water jets from all directions.
This means an IP55 fan can withstand dusty industrial conditions and exposure to water spray, making it more durable than standard IP20 or IP44 fans.
At PBM, we offer a range of IP55-rated fans tailored for demanding environments:
IP55 Backward Curved Centrifugal Fan – High efficiency, ideal for HVAC and industrial ventilation.
IP55 Axial Fan – Reliable cooling for electronics, IT equipment, and outdoor air systems.
IP55 Single Inlet Blower – Compact design for machinery cooling.
IP55 Dual Inlet Blower – High airflow capacity, suitable for large refrigeration units.
IP55 Forward Curved Centrifugal Fan – Compact solution for confined spaces requiring moderate airflow.
In facilities such as woodworking plants, textile factories, or cement processing, airborne dust is unavoidable. IP55 centrifugal and axial fans prevent dust ingress, protecting motors and extending service life.
IP55 fans can withstand rain, humidity, or cleaning sprays, making them suitable for outdoor HVAC systems, cold chain storage, and food processing plants where hygiene requires regular washing.
With EC motor technology, PBM IP55 fans offer maintenance-free operation with longer lifespans compared to conventional fans.
By using Electronically Commutated (EC) motors, PBM’s IP55 fans reduce energy consumption, supporting sustainability and lowering operating costs.
Available in centrifugal and axial designs, IP55 fans can be integrated into a wide range of systems, from HVAC and medical equipment to industrial cooling and data centers.
Moisture and condensation are common in cold storage facilities. IP55 centrifugal fans ensure reliable air circulation and temperature control without risk of water damage.
Continuous cooling is critical in server rooms. IP55 axial fans provide dependable airflow in environments where dust and humidity could otherwise cause equipment failure.
Hygienic environments require frequent washing and cleaning. IP55 fans resist water spray and guarantee stable ventilation performance.
From rooftop units to external ventilation ducts, IP55 fans withstand rain, dust, and wind, making them suitable for all-weather operation.
In heavy-duty machinery, fans often face vibration, dust, and exposure to lubricants. IP55-rated blowers ensure reliable cooling under these harsh conditions.
