- Multiply that result × 60 to verify the necessary airflow.
- Install the extractor and connect the activated carbon filter in-line.
- Join the flexible ducts and seal with aluminum tape to prevent leaks.
- Maintain negative pressure in the grow space for total odor control.
- Periodically check the filter's condition and replace it when it loses effectiveness.

Frequently asked questions
-
Proporciona un caudal de extracción de hasta 4250 m³/h a través de un extractor de 315 mm de boca. Ese volumen está pensado para cuartos de cultivo de gran superficie. Asegura una renovación constante del aire durante todo el ciclo.
-
Incluye el extractor centrífugo de gran caudal, un filtro de carbón activo compatible con la boca del extractor, tubo de aluminio flexible y las abrazaderas metálicas necesarias. Con eso tienes una instalación rápida y segura sin comprar nada más. Todo está dimensionado para trabajar en conjunto.
-
Al renovar el aire de forma constante, mantiene la temperatura estable y la humedad bajo control en la sala. Eso se traduce en un entorno de cultivo más previsible y en plantas más sanas. Además elimina los olores gracias al filtro de carbón.
-
Utiliza carbón activo virgen de origen mineral y alta densidad, pensado para eliminar los olores por completo incluso en grandes volúmenes. El carbón virgen es también lo que da al filtro una vida útil larga. Es la parte del sistema que más conviene no escatimar.
-
Es la opción ideal para growers profesionales que necesitan un sistema robusto, silencioso y duradero, capaz de gestionar grandes volúmenes de aire. Encaja en salas de cultivo industriales o invernaderos. Para un armario doméstico resultaría excesivo.
-
Sí, el diámetro de boca es de 315 mm y tanto el filtro como el tubo incluidos son compatibles con esa medida. Las abrazaderas metálicas del kit fijan las uniones para que no se muevan. Así evitas fugas y pérdidas de presión.
