Sound insulation hood:

According to the applicable environmental guidelines, sound insulation must be provided for installed Roots blowers.

The standard sound measurements with IKS sound insulation hoods provided sound insulation of up to a maximum of 20 dbA.

The sound cabins are equipped with removable, locked parts or with hinge doors to facilitate the service work.

When using a sound insulation hood, is the compressor unit, together with the sound insulation hood, mounted on a base frame and can be transported together by means of a forklift.

Lobe pump:

Structural features:

  • Rotary pistons consisting of three massive and dynamically balanced blades.
  • These rotary pistons rotate contact-free in a cast iron housing.
  • Continuously increasing compression achieved by the design of the housing -> pulsation is kept low right at the point of origin -> the gearbox is a heat-treated and refined helical gear according to DIN-6.
  • Gears that are mounted on the drive shaft with a conical seat without the use of a feather key.
  • Lubrication done by splash lubrication.
  • A process chamber, which is sealed off from the oil boxes with a multi-part labyrinth seal, with a condensate intermediate chamber.
  • Shaft seal which seals off the drive shaft
