Plastic deodorizing grilles, suitable for farm odor control systems

Farm exhaust gases are a formidable opponent: containing high levels of ammonia, hydrogen sulfide, and corrosive moisture, they rapidly degrade inferior packing materials, leading to frequent replacements, reduced purification efficiency, and unexpected costs. Our odor control grid packing is made from high-density polypropylene (PP) plastic, a material chosen for its exceptional durability in farm environments.

Excellent Corrosion and Chemical Resistance

PP plastic is unaffected by corrosive compounds in farm exhaust gases. Ammonia, fecal acids, and moisture—common in livestock barn and manure storage exhaust gases—do not affect its structure. Tests show that our PP packing maintains its integrity even after continuous exposure to farm exhaust gases for more than 5 years.

Lightweight and Extremely Durable

PP plastic achieves a perfect balance between strength and weight. Despite its lightweight nature, it is highly impact-resistant, able to withstand accidental impacts from agricultural equipment or debris in exhaust fumes. A pig farm reported that after three years of use, their PP filler showed no signs of cracking or deformation, even under the high-vibration conditions of a fan-driven exhaust system.

Maximizing the contact area between gas and the medium for deep purification

The spiderweb-like grille design creates thousands of tiny, uniform channels, forcing exhaust gas to flow slowly and evenly through the purification medium. This eliminates “dead zones” where gas might bypass treatment, ensuring full contact between odor-causing compounds (ammonia, hydrogen sulfide, volatile organic compounds) and the medium.

Our grille design maximizes the contact area while minimizing airflow resistance, which is crucial for reducing the load on exhaust fans. Lower resistance means 15% to 20% savings in electricity when the fan delivers the same volume of gas, thus reducing the farm’s energy costs.

Every farm is different, and our PP deodorizing grille filler is designed to adapt to various environments. We offer multiple configurations to fit common farm exhaust systems:

Why choose our PP plastic deodorizing grille filler?

Long service life: Reliably operates for over 5 years in harsh farm exhaust environments without premature replacement.

High efficiency: The spiderweb-like design maximizes the contact area between gas and the medium, purifying over 80% of odors.

Safe: Non-toxic and safe for farms, it will not harm livestock or pollute organic farming operations.
