Circulation Fan NTA447

Circulation Fan NTA447

The 4 Blade 47 cm Circulation Fan is designed for the movement of air and uniform temperature and humidity and is ideal for industrial halls, greenhouses, mushroom production halls, Poultry Farms, and livestock.

This fan is installed on the ceiling and high altitude below the roof of halls.

The circular fan reduces the pressure loss by improving the performance of the main ventilation system and increasing the efficiency of cooling systems (coolers) and pro-fan and heating systems such as a fan heater and jet heater.

During the winter, low-density air wants to rise to the highest part of the room and accumulate below.

Since temperature is generally important in lower and middle elevations, temperature sensors are installed at low altitudes, and the accumulation of hot air at high altitudes causes that circuit breaker system issue a close delay command so it can lead to an increase of fuel consumption.

In the summer, according to the operating of the main ventilation system (running at full speed), the heated air accumulates below the ceiling so the ventilator interrupts and the hall atmosphere will be humid.

By installing a circulation fan, hot air exhaust as quickly as possible.
