Description

We have broad and long experience of reparing impactors, predominantly the NGI. Examples are:

  1. Nickel coating of NGI body and pre-separator
  2. TiN layer on USP induction port and pre-separator tapered male ends
  3. Polish severely scratched surfaces, such as joints between impactor parts (the NGI stage 1 female entry port is vulnerable) and surfaces around the entry of the induction port. Any measures are discussed with the customers prior, since some parts simply have reached end-of-life.
  4. Reconditioning nozzles on stages where the holes regain their original specifications, or repairing complete stages. Which are verified by optical or mechanical inspections, or through method for determining stage pressure drop:Impactor Nozzle Diameter Measurement NGI

If a component has reached end-of-life, rest assured, we have the full range of refurbished impactor components available at an affordable price. (See the images for further descriptions.)
