The ABM Hexseal Difference


APM Hexseal’s core mission is to provide sealing solutions that function in the world’s most hostile environments, which means that we have explored different types of elastomeric materials in order to understand and improve the performance characteristics of our products.

The elastomeric materials offered by APM Hexseal for their products can be changed depending on the intended use or environmental conditions – whether there might be exposure to extreme high or low temperatures, oils, chemicals or solvents, and even sunlight, oxygen, or ozone.  Other factors to consider are abrasion resistance, elongation percentage, and compression.

Throughout its history, APM Hexseal has obtained numerous patents for environmental seals for toggle, pushbutton, rocker and rotary style switches and potentiometers, and for lever, toggle and pushbutton circuit breakers.

Below is a list of ABM Hexseal’s different sealing elastomers for Sealing Boots and Bushings along with their special characteristics:

ebm-papst Diagonal Compact Fans


The market requirements for electronics cooling are constantly increasing and necessitate ever more intelligent high-performance solutions. Up until now tubeaxial fans have been widely used. These function optimally where there is little pressure loss.

If this increases on account of a higher power density or increasing filter clogging, tubeaxial fans soon reach their limits. The consequence: Inefficient, noisy fan operation.

The new diagonal compact module from ebm-papst can now provide the ideal solution:

As its characteristic curve is less sensitive to pressure, the diagonal fan permits efficient operation even with increasing filter clogging or a higher power density. In addition, higher air performance provides enhanced cooling action, which makes this the ideal solution for demanding applications requiring intensive cooling. Simple mounting and installation round off the advantages of this new concept.

The advantages of the diagonal compact module:

  • Pressure-insensitive diagonal fan: constant characteristic curve, long filter service life, longer maintenance intervals
  • Up to 49% lower energy consumption
  • Reduced power loss and hence improved cooling action and longer service life
  • Up to 50% better air performance in nominal operation
  • Demand-based air flow thanks to speed control
  • Up to 7 dB (A) sound reduction
  • Shallow installation depth
  • Completely pre-assembled – Plug & Play
  • Mechanical compatibility with existing industry standard for uncomplicated retrofitting and exchange
