The new compact filter NKJ from NESTRO was photographed today outside the factory in Schkölen - almost on a “green field”. A crane was necessary to place the extraction unit on one of four discharge units. It happened so quickly that the photographer finished all the shots after just three hours.
With this new JET filter series type NKJ, the German NESTRO Lufttechnik GmbH offers to the woodworking industry a new compact device for outdoor installation in four performance classes for air volumes from 13,000 to 32,000 m³/h. Each of the new four filter types consists of just three pre-assembled elements that are simply placed on top of each other and screwed together on site:
• An upper compressed-air unit,
• a middle filter/fan unit with intake and return air sections plus
• one of four different base/discharge units (bins, briquetting press, rotary valve, swiss container).
In the suction section, the air flow is calmed using a pre separation chamber. Coarse chips are separated from fine dust at an early stage using gravity. The dust settles on the filter bags, which are cleaned at regular intervals using compressed-air pulses from the upper section. The so-called filter cake is blown off, falls into the funnel and is discharged. The device works as a clean gas filter. The frequency-controlled fan/fans with closed high-performance impellers (efficiency class IE3) are located behind the filter hoses and therefore only transport clean air. The filtered air with a certified residual dust content of < 0.1 mg/m² is released to the outside or returned to the hall.
