Metallic Sleeve 200 mm. Odor Resistant is a connector for 200 mm ducts that houses a neutralizing block such as Ona Block or Zerum Block. It reduces residual odor in Indoor cultivation, provides discretion, and improves the exhaust in indoor grow cabinets with forced extraction.

The 200 mm Metal Sleeve Odor Control works as the final stage of air treatment within the extraction line. The metal body incorporates a cylindrical housing where a deodorizing block fits (commonly compatible with Ona Block and Zerum Block).
The airflow passes through the inside of the sleeve, comes into contact with the aromatic surface, and attenuates remaining volatile compounds that, even after the carbon filter, may remain in the flow. The result is more neutral air to the outside, ideal for residential or commercial environments sensitive to odor emissions.
This piece works together with filters, extractors, and ducts, reinforcing the system's discretion without additional power consumption. The metal construction offers mechanical resistance, thermal stability, and easy maintenance; simply check for tightness, clean accumulated dust, and replace the block when it loses intensity.
Integration is done with standard 200 mm clamps and flexible or rigid ducting, without complex adapters.
This accessory stands out for its low cost and remarkable effectiveness during flowering phases, drying rooms, and hot periods, when terpene volatilization increases.
This is a practical solution within the cannabis growing accessories catalog for those seeking extra odor control in medium and large installations found in any Grow Shop in Spain.
Designed for Indoor growing projects with 200 mm extraction, this sleeve provides a consistent aromatic finish in medium/high volume indoor grow tents and technical rooms. Direct installation at the final section optimizes contact time with the block and helps deliver a more discreet flow to the street.
It is used to neutralize residual odors and aromatize the flow before the outside exit. The block reduces odorous compounds that may escape despite the carbon filter, improving environmental perception and reducing nuisance in neighborhoods or areas with stricter regulations.
This metal connector is part of the cannabis growing accessories category focused on air treatment. Real compatibility with Ona Block and Zerum Block, assembly with 200 mm clamps, and perfect coexistence with extractors, filters, and elbows commonly used in Grow Shop in Spain installations.
Especially recommended during flowering, drying rooms, and hot periods with high terpene emission. Useful in commercial basements, homes with close neighbors, and environments where odor discretion is a priority. Also convenient between cycles to maintain a more pleasant exhaust while renewing the room's air.
