Centrifugal Blowers – Single Inlet

Single Inlet Centrifugal Blowers are engineered for efficiency, durability, and focused air delivery. Designed to draw air from one side of the blower and expel it at 90 degrees, these units are ideal for systems requiring directed airflow under high static pressure.

Their space-saving design, coupled with robust construction and CE-certified motors, make them perfect for a wide range of industrial and commercial ventilation applications.

Focused Flow | Space-Saving Design | Consistent Output

Specifications:

Single Inlet signifies that the air is drawn from one side of the blower only.

Model Description

Precision at Every Step — From Winding to Delivery

At VBM Enterprises, every product goes through a systematic, quality-controlled process to ensure high performance, durability, and safety. Here’s how we bring excellence to every fan and motor we build:

Step 1: Coil Winding & Motor Assembly

We begin with precision winding of coils to create efficient fan motors, followed by connecting lead wires to ensure electrical integrity.

Step 2: Motor Testing

Every motor undergoes Ohm value testing to check coil resistance, ensuring proper functionality from the start.

Step 3: Hi-POT & Impulse Testing

We perform high-potential and impulse testing to verify insulation strength between coils and motor casings, enhancing product safety and reliability.

Step 4: Motor Mounting & Impeller Balancing

Change the color to match your brand or vision, add your logo and more.

Step 5: Final Assembly & Quality Checks

Impellers are assembled to the motors, followed by pre-delivery inspections checking for vibration, wattage, and current to ensure optimal performance.

Step 6: Final Testing & Packing

A final round of Hi-POT insulation testing is conducted before products are carefully packed for delivery — guaranteeing both safety and quality in transit.
