24"x24" Ring Panel Filter (Secondary) 24/case The 24” x 24” x 1” 2-Ply Ring Panel serves as the second stage in a multi-layered air filtration system. Positioned after the pre-filter, this durable ring panel is specifically designed to capture particles as small as 1 micron, significantly enhancing air quality while shielding the high-efficiency HEPA filter from premature clogging and wear. Commonly used in commercial air scrubbers and negative air machines, this 2-ply filter panel maximizes system performance by maintaining airflow efficiency and reducing the frequency of costly HEPA filter replacements. Key Features: Dimensions: 24” x 24” x 1” 2-Ply construction for enhanced particle capture (1 micron and larger) Strategically placed as a second-stage filter for optimal system protection Extends the life of the final-stage HEPA filter Change recommended when airflow decreases or pressure gauge exceeds 2.6" W.C. (high speed) or 1.9" W.C. (low speed) This 2-ply ring panel filter is a critical component in maintaining clean, safe, and efficient operation in air filtration systems used in abatement, remediation, and construction environments. Abatement Technologies H2KM, BDK2M and ANY other Air Scrubber which requires a 24"x24" Primary Filter Size: 24"x24" Quantity Per Case: 24 Filters
