Eye Bolt Multi-Bag Filter

Product Overview

The CMI Eye-Bolt Multi-Bag Filter Housing is a cost-effective and versatile solution for industrial liquid filtration. Designed with a balanced eye-bolt closure system, it provides reliable sealing performance with simple operation and low maintenance cost.

This model is widely used in water treatment, chemical processing, coatings, and general industrial applications where regular bag replacement is required, but ultra-fast opening is not critical.

The side-inlet and bottom-outlet configuration ensures complete drainage and stable filtration performance. The hinged lid allows single-operator access without lifting or removing the cover.

All housings can be designed and manufactured in accordance with ASME Section VIII, Division 1 upon request.

Key Features

• Economical eye-bolt closure design
  A practical and cost-efficient solution for most industrial filtration systems.
• Balanced hinged lid structure
  The lid remains supported during opening, reducing operator fatigue and improving safety.
• Reliable sealing performance
  Uniform gasket compression ensures stable sealing under low- to medium-pressure conditions.
• Low maintenance requirements
  Simple mechanical structure with fewer components reduces long-term operating cost.
• Complete drainage configuration
  Side inlet and bottom outlet minimize residual liquid and improve maintenance safety.
• Universal filter bag compatibility
  Compatible with standard Size 1 and Size 2 filter bags (metal or plastic ring).
• Smooth surface finish
  Easy cleaning and suitable for general industrial environments.
