Fan lengths up to 1780mm:

Using our longer fans means you need less of them to match the length of your trench heating unit. The benefits of this include:

• Lower costs
• Faster assembly time
• Lower power consumption
• Lower motor noise
• More uniform airflow

Brushless DC (BLDC/EC) motor:

Introducing all-new Airtek brushless DC (BLDC/EC) motors. Featuring 3-phase drive technology and built in sinewave controller, our motors have been optimised for low noise, smooth running, high efficiency and improved EMC (Electromagnetic Compatibility).

Speed controllable:

Speed controllable by 0-10V DC input providing compatibility with Heating, Ventilating, Air Conditioning (HVAC) controls and building management systems (BMS). The 0-10V input requires hardly any current, allowing you to manage many fans from just one controller.

Constant speed function & soft-start:

The constant speed function maintains continual fan speed independent of static pressure against the fan. The fan speed and noise levels are always precisely as you set them, even if the air pressure against the fan changes (e.g. blocked filter, grill covered by an object). Uniform speeds are maintained throughout the trench heating system, even when different length fans are used. The motors incorporate a soft-start feature for reduced load and long life.

Black coated fan wheels, housings and guards:

• Reduced visibility
• Increased corrosion resistance

High quality ball bearings in motor and fan wheels:

• Low noise
• Long life
