VENTS TT PRO 250 P – professional inline fan Ø250 mm

VENTS TT PRO 250 P is a high-performance two-speed inline fan with a mixed-flow axial-centrifugal impeller, designed for ventilating spaces that require high airflow and high static pressure. It is suitable for ventilation systems in greenhouses, grow rooms, production and commercial facilities, as well as residential applications. Thanks to its compact design and removable motor block, the fan is easy to install, service and clean.

VENTS TT PRO 250 P is part of the professional TT PRO series, developed for ductwork with high aerodynamic resistance. The combined axial and centrifugal fan technology provides significantly higher pressure than standard axial fans while maintaining high performance and relatively low noise levels.

The housing is made of high-quality impact-resistant polypropylene plastic, corrosion-resistant and suitable for operation in humid environments. The fan is equipped with a two-speed single-phase AC motor mounted on double-sealed ball bearings, providing a service life of up to 40 000 hours of continuous operation. Built-in thermal protection prevents motor overheating and automatically switches it off in the event of overload.

One of the model's main advantages is the removable central motor block, which allows easy servicing and cleaning without removing the ductwork. This significantly reduces maintenance time and makes ventilation-system upkeep easier. The fan can be installed horizontally or vertically, in any position, directly into round ductwork with a diameter of 250 mm.

📋 Instructions for use

1. Install the fan in a round Ø250 mm air duct.
2. Follow the airflow direction indicated by the arrow on the housing.
3. Connect the fan to the electrical supply according to the manufacturer's diagram.
4. Select the desired speed using a suitable two-speed switch or compatible controller.
5. Inspect the fan periodically and clean the impeller when necessary.
6. For servicing, remove the motor block without dismantling the air ducts.

⚠️ Important: The fan is designed to convey clean air at temperatures up to 60°C. Do not use the unit to extract explosive, flammable or heavily contaminated gases and dust particles. Ensure free access for periodic maintenance during installation.

💡 Tip from Urban Botaniks: For maximum efficiency in grow rooms, pair the TT PRO 250 P with a quality Ø250 mm carbon filter and sound-insulated air ducts. This ensures optimal air exchange, effective odour control and quieter operation of the whole ventilation system.
