Understanding Filter Headers: A Guide to Rigid Cell Filters

When it comes to rigid cell filters, understanding the role of filter headers is crucial for effective air filtration and system performance. Headers serve not only as a means of securing the filter within its housing but also play a significant role in the overall design and functionality of the filtration system. Let’s explore the common configurations of filter headers and their applications.

Box Style (No Header)

The box style filter features a basic square frame without any headers. This design is straightforward and often used in applications where the filter can be easily inserted and removed from its housing without additional securing mechanisms. While this configuration is simple, it may not provide the same level of stability as headered options. Box style filters are best suited for environments where quick replacements are necessary and space is not a constraint.

Single Header

The single header configuration includes one header positioned on the air-entering side of the filter. This design helps to secure the filter in place, preventing any movement or bypassing of air around the edges. Single header filters are particularly beneficial in systems where the airflow direction is constant, ensuring that the filter performs optimally by maintaining a tight seal. They are commonly used in side-access housings, offering a balance between stability and ease of access for maintenance.

Double Header

In contrast to the single header, double header filters feature headers on both the air-entering and air-leaving sides. This dual-header design significantly enhances the filter’s stability, making it an excellent choice for high-velocity air applications. Double header filters minimize the risk of air bypass, ensuring that all incoming air passes through the filter media. This configuration is ideal for environments with varying airflow patterns or where consistent performance is critical.

Single/Double Header Filters

Filters with single or double headers are specifically designed for use in side-access housings. Their construction allows for easy installation and replacement, making them a practical choice for facilities that require frequent maintenance. The secure fit provided by the headers ensures that these filters can withstand the rigors of air movement without compromising efficiency.

Box Style & Double Header Filters

Box style filters with double headers are perfect for face-loading systems. This configuration combines the benefits of a robust header system with the ease of a box-style design. These filters are particularly useful in applications where space is limited yet a strong, secure fit is essential. The double headers provide additional support, ensuring the filter remains firmly in place even under fluctuating airflow conditions.

Conclusion

Understanding the different configurations of filter headers is essential for selecting the right rigid cell filter for your specific application. Whether opting for a box style filter, a single header, or a double header configuration, each design offers unique advantages tailored to various operational needs. By considering the specific requirements of your filtration system, you can ensure optimal performance and longevity of your filters.
