Deshengxin BFU - Frequently Asked Questions (FAQs)
Basic Knowledge
-
What is a BFU and how does it work?
A BFU (Blower Filter Unit) is a self-contained air purification module that combines a fan and a high-efficiency filter (HEPA/ULPA) to provide laminar airflow in cleanrooms and controlled environments. -
What's the difference between a BFU and an FFU?
While often used interchangeably, BFU typically emphasizes the integrated blower for higher static pressure, while FFU is a more general term. Deshengxin BFUs are engineered for robust performance. -
Where are Deshengxin BFUs commonly used?
They are essential in pharmaceuticals, semiconductor manufacturing, biotechnology labs, hospital operating rooms, and electronics assembly where ultra-clean air is critical.
Technical Specifications
-
What cleanroom classes can Deshengxin BFUs achieve?
With proper HEPA/ULPA filters, our BFUs can maintain environments from ISO Class 1 to ISO Class 9. -
What filter efficiencies are available?
We offer HEPA filters (H13-H14) and ULPA filters (U15-U17), with efficiencies up to 99.9995% on 0.12μm particles. -
What are the standard sizes available?
Common sizes include 575x575mm (2'x2'), 1175x575mm (4'x2'), and 1175x1175mm (4'x4'). Custom sizes are available. -
What is the typical airflow velocity?
Adjustable from 0.35 to 0.55 m/s, ensuring stable laminar flow for various cleanroom requirements.
Motor and Control
-
What are the benefits of EC motors in your BFUs?
Our EC motors offer higher energy efficiency, precise speed control, longer lifespan, and lower heat generation compared to AC motors. -
