TT Silent/Dalap AP Fan 250mm, 1050/1330m3/h

Ultra-Quiet Inline Fan for Professional Ventilation

The TT Silent/Dalap AP 250 inline duct fan represents the pinnacle of quiet ventilation technology, delivering exceptional airflow performance while maintaining whisper-quiet operation. This extremely quiet ventilation fan is engineered for professional grow rooms, hydroponics systems, and indoor cultivation where noise control is paramount. Compatible with all standard 250mm ducting systems, this fan excels in high-pressure applications where traditional fans struggle to maintain efficiency.

The TT Silent AP series bridges the gap between axial and radial fan technologies, combining the high airflow capacity of axial fans with the pressure handling capabilities of radial designs. This dual-speed inline fan features advanced engineering that makes it ideal for complex ventilation systems with extended ductwork runs and multiple bends.

Key Features and Performance Benefits

This professional-grade inline fan incorporates cutting-edge design elements that set it apart from standard ventilation equipment. The dual-speed motor with thermal protection ensures reliable operation under varying load conditions while protecting against overheating damage.

• Dual-speed motor with thermal overload protection for reliable long-term operation
• Premium ball bearings extending operational life up to 40,000 hours of continuous use
• Semi-radial metal impeller blades engineered for maximum airflow velocity and pressure
• Polymer-coated steel housing providing durability and corrosion resistance
• Reinforced plastic rotor assembly for lightweight yet robust construction
• Vibration-free operation with advanced balancing technology
• External junction box for simplified electrical connections and maintenance access

Installation and Application Guidelines

The TT Silent/Dalap AP 250 offers exceptional versatility with both horizontal and vertical mounting options. The external mounting bracket allows for secure wall or ceiling installation, making it suitable for various grow room configurations. This inline fan performs optimally in ducting systems up to 45 meters in length, maintaining consistent airflow even through complex ventilation networks.

The fan operates at two distinct speed settings: the low setting delivers 1050 m³/h at 127W power consumption and 1965 RPM, while the high setting achieves 1330 m³/h at 178W and 2495 RPM. The acoustic performance is remarkable, generating only 34dBA on low speed and 38dBA on high speed, making it virtually silent during operation.

Speed control can be configured permanently before installation or managed through an external speed controller (sold separately). The single-phase motor with ball bearing construction guarantees maximum performance in both horizontal and vertical positions, providing flexibility for any installation requirement.

Ideal Applications and User Recommendations

This professional inline fan excels in grow rooms, indoor gardens, hydroponics systems, and any application requiring quiet, efficient ventilation. It's particularly well-suited for residential growing operations where noise levels must be minimized, as well as commercial facilities with strict acoustic requirements.

The TT Silent AP 250 performs exceptionally well when paired with air filtration systems and climate control equipment. For optimal performance, consider combining with appropriate ducting accessories and speed controllers to create a complete ventilation solution tailored to your specific growing environment.
