This product features a helical spring-type metal structure with excellent elasticity and compressibility; it provides support for dust-collection filter bags, preventing them from excessively contracting or deforming due to negative pressure during the filtration process.

  • Retractable spring structure

Can be compressed along the axial direction, reducing the space required for transport and storage.

  • Easy installation and maintenance

Suitable for dust collection equipment where space is limited or filter bags require frequent replacement.
