Features

Eight carbon trays at 56 kg total media weight — exactly double the CF-4000’s tray count and carbon mass — matched to the organic load carried by 7,000 – 8,000 CMH of two- to three-station commercial kitchen exhaust
The same 550 mg/g iodine value and 630 – 650 g/L filling density as the CF-4000, ensuring consistent adsorption performance per kilogram of carbon regardless of model size
Carbon pellet hardness above 93% prevents fragmentation into dust under the mechanical vibration of 4,118 – 4,706 CFM airflow across eight tray surfaces over a 3 – 5 month service interval
200 Pa wind resistance — identical to the CF-4000 — confirms that the exhaust fan does not require uprating when upgrading from a CF-4000 installation to this larger model in an existing duct system
W 1,020 mm × H 530 mm flange connects directly to wide-body rectangular exhaust duct trunks typical of two- to three-station commercial kitchen exhaust systems without a custom plenum adapter
At 90 kg gross weight, mechanical handling equipment is required for positioning — a planning factor that distinguishes this unit from the 55 kg CF-4000 and must be accounted for in the installation programme
This model’s airflow range matches the HEL-8000 Ecology Unit exactly, making it the direct carbon filter pairing for HEL-8000 installations where odour control beyond the electrostatic stage is required

The CF-8000 Activated Carbon Filter processes 7,000 – 8,000 CMH (4,118 – 4,706 CFM) through eight carbon trays carrying 56 kg of activated carbon, handling odour and VOC removal for medium-to-large commercial kitchen exhausts including dual-station and three-station configurations where a single-tray unit cannot absorb the compound load. Its airflow range is matched exactly to the HEL-8000 Ecology Unit, making it the designated carbon filtration stage for HEL-8000 installations in kitchens where local regulations require odour control in addition to particulate and grease capture.

The CF-8000’s eight trays at 56 kg carbon weight represent a precisely doubled capacity relative to the CF-4000 — not an approximation but an exact doubling of both tray count and carbon mass. This means the CF-8000 adsorbs the same organic concentration per unit volume of exhaust air as the CF-4000, sustaining the same 3 – 5 month service interval even though it processes twice the airflow. The W 1,020 mm × H 530 mm duct flange accepts standard wide-body rectangular duct trunk connections without a transition piece, and the identical 200 Pa wind resistance to the CF-4000 ensures that the existing exhaust fan selection remains valid when this unit is specified instead of or in addition to a smaller carbon filter.

At 90 kg gross weight, the CF-8000 requires forklift or crane positioning during installation — a logistics requirement that should be confirmed with the building’s site access constraints before procurement. For systems processing less than 4,000 CMH, the CF-4000 provides the same carbon quality specification in a 55 kg cabinet that does not require mechanical handling; for exhausts exceeding 8,000 CMH and reaching up to 12,000 CMH, the CF-12000 is the correct scale-up with twelve trays and 84 kg of carbon media.
