Precision Filtration for Critical Spaces

Excelling in high-efficiency air filtration, these secondary and final filters are engineered for applications demanding the utmost particulate control, such as clean rooms and pharmaceutical or electronic manufacturing areas. Their robust construction and adherence to EN 1822, ISO 29463, and ISO 14644 standards make them a prime choice for spaces requiring up to 99.99% efficiency at 0.3 micron.

Versatile Installation and Customization

Available in box or flange types, these filters fit ceiling, wall, or duct mounts, and come in customizable sizes, shapes (rectangular or square), and frame thickness options. Whether your application demands a specific pressure drop, diameter, or flow rate, solutions can be tailored for seamless integration into new or existing setups.

Durable Construction for Demanding Environments

Constructed with high-grade galvanized steel, aluminium, or stainless steel frames, and equipped with synthetic fiber media, these filters are designed to endure high humidity (up to 100%) and temperature ranges up to 80C. Choice of polyurethane or epoxy sealants and adaptable gasket materials ensure lasting performance in the most challenging conditions.

FAQs of Secondary & Final Filters:

Q: How are secondary and final filters used in clean room and pharmaceutical environments?

A: These filters are integral to maintaining ultra-clean air by trapping up to 99.99% of airborne particles at 0.3 micron, essential in environments where air purity is critical to product quality and safetyin clean rooms, hospitals, electronics, and pharma facilities.

Q: What types of media and frame options are available for these filters?

A: The filters are offered with synthetic fiber HEPA or ULPA media and constructed with galvanized steel, aluminium, or stainless steel frames. Frame thickness can be selected (25 mm, 50 mm, or 100 mm) to fit your specific application needs.

Q: When should I replace or maintain my secondary and final filters?

A: Replacement is recommended when the filters approach their specified initial pressure drop (typically 2535 mm WG), or as prescribed by operational protocols to maintain high filtration efficiency. Regular inspection ensures optimal performance and adherence to clean room standards.

Q: Where can these filters be mounted within a building or facility?

A: They are designed for ceiling, wall, or duct mounting, making them suitable for integration into various HVAC systems or dedicated filtration units in critical areas such as pharma production, hospitals, or clean rooms.

Q: What is the process for selecting the appropriate configuration for my application?

A: Selection involves evaluating air velocity (0.45 0.05 m/sec), desired flow rate (10003000 CFM or custom), filter efficiency requirements, frame size, and installation type (box or flange, rigid frame). Consulting with a supplier or manufacturer helps ensure the best match for your project.

Q: How do the filter features benefit my facilitys operations?

A: Benefits include superior particulate retention, high durability under demanding conditions (up to 100% RH and 80C), customizable sizing, and long service life, ensuring minimal downtime and exterior air contamination risk in sensitive environments.

Q: What international standards do these filters comply with?

A: These filters meet the rigorous quality and performance benchmarks set by EN 1822, ISO 29463, and ISO 14644, assuring performance for critical air filtration requirements worldwide.
