Features

Twelve carbon trays at 84 kg total media weight — the largest configuration in the CF series — sized for exhaust systems between 10,000 and 12,000 CMH serving multiple cooking lines in high-volume institutional or industrial food service operations
The 84 kg carbon mass adsorbs 50% more organic load per service interval than the CF-8000, reducing the annual carbon replacement frequency in high-intensity cooking operations where the CF-8000’s interval would already reach its lower bound of three months
Identical 550 mg/g iodine value and 630 – 650 g/L filling density across all CF models means each kilogram of carbon delivers the same adsorption performance regardless of which model size is installed
200 Pa wind resistance held constant across the CF-4000, CF-8000, and CF-12000 confirms that exhaust fan selections valid for the smaller models remain valid for the CF-12000, with no fan uprating required when scaling up carbon filtration capacity
W 1,560 mm × H 530 mm flange dimension accepts the wide-body rectangular duct trunks used in large-scale commercial exhaust systems, connecting without a custom plenum transition
Cabinet depth (590 mm) and height (590 mm) are identical to the CF-8000, so the CF-12000 occupies the same duct-side installation depth — only the 1,690 mm width requires additional clearance planning relative to the CF-8000’s 1,155 mm
At 120 kg gross weight, the CF-12000 requires forklift positioning with a minimum 500 kg capacity rated machine; confirming site access for this equipment before delivery is a mandatory pre-installation step

The CF-12000 Activated Carbon Filter handles 10,000 – 12,000 CMH (5,882 – 7,059 CFM) through twelve carbon trays loaded with 84 kg of activated carbon — the largest configuration in the CF series — designed for banquet kitchens operating multiple cooking lines simultaneously, institutional cafeteria operations serving several hundred covers per service, and food processing facilities where exhaust volumes exceed the CF-8000’s 8,000 CMH ceiling. At 120 kg gross weight, it requires forklift positioning and structural verification of the mounting surface before installation begins.

The three-model CF series scales linearly: CF-4000 uses four trays at 13 – 14 kg carbon, CF-8000 doubles to eight trays at 56 kg, and CF-12000 extends to twelve trays at 84 kg — each step adding four trays and approximately 28 kg of media while keeping the cabinet depth and height constant at approximately 590 mm. Only the width grows: 620 mm for CF-4000, 1,155 mm for CF-8000, and 1,690 mm for CF-12000. This consistent depth dimension means the CF-12000 fits in the same duct-side wall clearance as its smaller siblings; only the additional 535 mm of width beyond the CF-8000 needs to be confirmed in the installation space before ordering. The W 1,560 × H 530 mm flange connects directly to wide rectangular trunk ducts standard in large commercial exhaust systems without a bespoke adapter.

For exhausts in the 7,000 – 8,000 CMH range, the CF-8000 provides equivalent carbon quality and the same 200 Pa wind resistance in a 90 kg cabinet that is 535 mm narrower and requires less clearance on-site. The CF-12000 becomes the correct specification when sustained cooking load or regulatory odour discharge limits would exhaust the CF-8000’s 56 kg carbon bed before the five-month upper bound of its service interval, making the additional 28 kg of adsorption capacity a functional requirement rather than an oversizing choice.
