Product Description

Product Description

The Rigid Mesh Coated Pleated G4 Paper Frame Primary Air Filter is a high-performance disposable panel filter engineered for HVAC pre-filtration. This rigid pleated air filter features a unique coated wire mesh support on the downstream side, which stabilizes the pleats and prevents media damage even under variable airflow conditions. The moisture-resistant paper frame ensures dimensional stability in humid environments, while the synthetic fiber media provides efficient particle capture with low resistance. 

Designed as a cost-effective solution, this G4 pleated air filter effectively extends the service life of downstream medium and HEPA filters, reducing overall system maintenance frequency and operational costs.

Product Features

As a rigid pleated air filter with superior structural integrity, this product delivers consistent performance and long service life. 
The coated mesh reinforcement locks each pleat in place, preventing sagging and media fatigue. 
The moisture-resistant paper frame resists warping in high-humidity conditions, ensuring a reliable seal within the filter rack. 
With G4 (MERV 8) efficiency, this disposable panel filter effectively captures lint, dust, pollen, and other coarse particulates. Its low initial resistance (50-70 Pa) reduces fan energy consumption, while the high dust-holding capacity extends replacement intervals. 
The lightweight, rigid design simplifies handling and installation, minimizing labor time.

Product Applications

This MERV 8 filter is ideally suited as a primary pre-filter in commercial and industrial ventilation systems. 
Installed upstream of AHUs, fan coil units, and air handling systems, this disposable panel filter protects sensitive cooling/heating coils from fouling, thereby maintaining system thermal efficiency. 
Common end-user segments include office buildings, hospitals, schools, data centers, manufacturing facilities, and cleanrooms. 
The filter is also widely used in air compressor intakes, gas turbine pre-filtration, and paint booth supply air. 
By capturing large particles before they enter the ductwork, this rigid pleated air filter significantly reduces cleaning costs for downstream components and enhances overall indoor air quality.
