Heavy Duty Virgin Activated Carbon Air Filter (38mm & 50mm Carbon Bed)
Commercial-grade Virgin Activated Carbon Filter designed for high-efficiency odor control and air purification in indoor growing environments and ventilation systems.
Carbon Spec & Density: 990mg/g (±20mg/g) high-adsorption virgin carbon in 38mm or 50mm bed thickness options.
Maximum Airflow Design: Inner & outer steel mesh engineered with 53% open area to maximize CFM and minimize static pressure.
Size Range: Flange sizes from 4″ (100mm) up to 12″ (300mm) with body lengths from 200mm to 1000mm.
Flange Options: Available in Galvanized, Black Powder-Coated, or Lightweight Aluminum finishes.
Extended Service Life: Reversible flange and base design allow flipped mounting to double filter longevity
Engineered for greenhouse, indoor cultivation, and industrial ventilation systems, our Activated Carbon Filters provide superior air purification and odor elimination. Packed with high-density, low-dust virgin activated carbon (990mg/g iodine rating), each filter ensures 100% air-contact coverage without air bypass. The durable steel housing features a 53% open mesh ratio to ensure high air throughput while reducing fan strain.
