Filter Screen Ventilation Grilles (SZR Series)
SZR Filter Screens (SZR-801 to SZR-806) are integrated ventilation and filtration accessories for enclosed equipment systems, detailed on Pages 87 and 88. Combining louvered housing, replaceable filter media, and modular construction, these grilles deliver multi-stage protection against dust, moisture, and contaminants while maintaining balanced airflow.
Functional Highlights for Enclosure Ventilation
Multi-Protection Design
The louvered structure provides splash resistance against water ingress, while the replaceable filter cotton traps particulates, offering both IP-rated environmental protection and clean airflow for sensitive components.
Scalable Sizing for All Enclosures
The series includes six models with opening dimensions from 80.5mm to 282mm, accommodating small control boxes to large industrial cabinets.
Minimal Maintenance Requirements
Filter elements are easily removable for cleaning or replacement, reducing long-term upkeep costs and equipment downtime.
Harsh-Environment Durability
Impact-resistant, UV-stabilized ABS housing withstands temperature fluctuations, chemical exposure, and outdoor conditions.
Quick-Install Mounting
Pre-configured mounting holes enable direct integration into standard cabinet cutouts, eliminating the need for custom modifications.
