The Jeven JLI-Turbo hood has been designed for kitchens where exhaust hoods with high efficiency grease extraction are needed and supply air units on the hoods are impossible to install.

JLI-Turbo is equipped with rotating filter units, damper plates and measurement taps. The TurboSwing filtering solution was developed for separating grease in professional kitchens. The fast rotating separation plate isolates even the smallest particles and throws them at high speed onto the outer edges of the separation chamber, from which grease and other particles drain into the collection basin. TurboSwing separates liquid grease and particles and they are then removed by means of a tap. During an annual/monthly check-up the TurboSwing dome and separation plate can easily be removed and washed in a dishwasher.

Functional principle

  1. Dirty air rises due to temperature differences against the ceiling of the hood.
  2. Dirty air is exhausted immediately through the TurboSwing units.
  3. Since TurboSwing’s air intake is placed close to the ceiling, the warmest dirty air is always exhausted through it. The ventilation efficiency is of the highest rate, because of the correct position of TurboSwing with respect to the kitchen equipment.
  4. Clean air is exhausted into the ducts.

JLI-Turbo functioning principle

Dirty air enters the TurboSwing (1). The separation plate rotates (2) grease and impurities are separated (3) and moved (4) to the edges of the separation chamber from where they drain into the collection basin (5). Liquid grease can be removed through the tap (6). Clean air exits to ducts (7).

Sound Power level, Lw

Sound power level Lw in each octave band is computed by adding the corresponding factor, Kok to the sound power level LpA.
Lw= LpA+Kok.

The hood shall be installed by hanging bars (f.ex. M8). These bars are not included in the delivery. Holes for the hanging bars should be drilled to the ceiling of the kitchen by using the shown fixture points.
Recommended height position of the hood is 2100-2200 mm.
Install plastic protective corner profiles on the lower end.

Depending on the kitchen’s utilization rate, grease should be removed daily / weekly or less frequently. Kitchen staff should always let the grease to run from the tap to a grease receiver. When degreasing, always use a work surface that meets the requirements. Always wait that kitchen equipment has cooled down before starting the procedure.

Wall surfaces are cleaned in connection with the kitchen normal cleaning or if necessary separately. Cleaning is carried out with detergent for stainless steel surfaces.


Hoods length, width and A, B dimensions can be chosen freely.
Max. module size is 3000 mm x 1800 mm.

Positioning of the hood

The size of the canopy is determined by the size of the kitchen equipment. The overhang depends on the type of equipment and the distance between the hood and the equipment.
For this type of equipment, the overhang should be at least 300 mm.
The typical distance between the hood side and the floor is 2100-2200 mm.
If the equipment has any doors that open upwards, make sure that there is enough distance to the canopy.
