AI Technical Summary
The filter structure in existing ventilation equipment is prone to loosening or displacement due to vibration during operation, which can lead to leakage of fluorine-containing gas and pose a safety hazard.
The locking mechanism works in conjunction with the arc-shaped support frame to stably fix the filter structure; the airtight connection is ensured through the tight fit between the sealing mechanism and the connecting pipe.
It improves the reliability of equipment operation, prevents the filter structure from loosening, ensures no leakage of fluorine-containing gas, and protects the safety of the production environment.
