Compact Pre-Filtration Solution for HVAC and Ventilation Systems
COARTEX Cassette Z-Line Filters are compact and efficient pre-filters designed for HVAC and industrial ventilation systems. The filter media is arranged in a Z-shaped pleat configuration, which increases the effective filtration surface area while maintaining low airflow resistance. This design allows high air volume handling with low pressure drop and high dust holding capacity.
Cassette Z-Line Filters are commonly used as the first filtration stage in air handling units (AHUs), ventilation systems, and air intake applications, protecting downstream filters and improving overall system performance.
Key Features
- Z-line pleated filter media for increased filtration surface
- High dust holding capacity with stable airflow performance
- Low initial pressure drop for energy-efficient operation
- Suitable for pre-filtration in HVAC and ventilation systems
- Available in disposable cardboard frames or reusable metal frames
- Metal cassette versions allow easy side access for quick filter media replacement
- Compatible with standard air handling units and filter housings
Typical Applications
Cassette Z-Line Filters are widely used in:
- Air Handling Units (AHUs)
- HVAC ventilation systems
- Commercial buildings and offices
- Hospitals and laboratories
- Industrial ventilation systems
- Air intake filtration systems
They help capture coarse dust particles and airborne contaminants, protecting fine filters and improving air quality in ventilation systems.
Construction Options
COARTEX Cassette Z-Line Filters are available in several configurations to suit different system requirements:
- Frame materials: Cardboard or galvanized steel cassette
- Filter media: Synthetic non-woven pleated media
- Filter classes: Typically G4 – M5
- Installation: Standard cassette filter housing or filter banks
The Z-pleated structure provides a large filtration surface in a compact frame, resulting in longer filter life and reliable filtration performance.
Why Choose COARTEX Cassette Z-Line Filters?
COARTEX Cassette Z-Line Filters provide an economical and reliable pre-filtration solution for HVAC systems. Their robust construction, high dust holding capacity, and low resistance help maintain efficient airflow while extending the service life of downstream filters such as bag filters and HEPA filters.
