Constantly high clean air flow with Njord air purifiers
Njord Constant Flow™
Optimum control setting of the air purifier that ensures constant high airpurification over time.
Njord air purifiers are controlled by default with the setting called constant flow control. Constant flow means that the air purifier’s fan adjusts its speed as the filters clog and the resistance of the air increases. This technology ensures a constant high cleaning of the air that guarantees the effect over time.
In all Njord air purifiers there is a mechanical pressure gauge that constantly measures the pressure across the filters. Depending on the pressure, the fan motor adjusts its speed so that you always get the same amount of clean air out of your air purifier. The fan speed increases the more clogged the air filters become.
When the pressure reaches a preset maximum pressure, the air purifier will alarm, a red light will light up. When this happens, you have a couple of weeks of operation left before you have to change the filters. With Njord Constant Flow™, you as a customer know that you have an optimal function where the air purifier delivers the same amount of clean air with the same high separation capacity over time.
There are several programming options to control your Njord air purifier, but we recommend the constant flow setting as it provides an optimal solution for the vast majority of businesses.
