Single Bag Filter – SF Series（Side Inlet / Eye-Bolt）

Product Overview

The CMI SF Series Side Inlet Single Bag Filter Housing is an industrial-grade filtration vessel designed for applications requiring higher pressure resistance, improved mechanical stability, and reliable long-term sealing performance.

Compared with the EF Series (economic V-clamp design), the SF Series features a robust eye-bolt closure structure and a side-inlet / bottom-outlet flow configuration, ensuring enhanced durability and consistent operation under varying pressure and flow conditions.

The housing is available in Size 1 / 2 / 3 / 4 configurations, with pressure ratings up to 10 bar (Size 1 & 2) and up to 21 bar (Size 3 & 4), making it suitable for a wide range of industrial processes.

It represents the standard industrial solution where both cost efficiency and mechanical strength are required.

Key Features

• Industrial eye-bolt closure design
  Provides stable and uniform sealing for long-term operation.
• Higher pressure capability
  Up to 21 bar, significantly stronger than V-clamp type housings.
• Side-inlet / bottom-outlet configuration
