Core Technical Features

  • Controlled Extraction Leverage:

    Extractor handles help technicians insert or remove high-pin-count modules without loading connectors or PCB structures unevenly.
  • Module Format Compatibility:

    Configuration options support 3U/6U VPX, CPCI, ASAAC, SEM, VITA 48, single-wide, double-wide, and custom module formats.
  • Material and Finish Options:

    Aerospace aluminum, stainless steel, and titanium options can be paired with anodize or passivation for environmental resistance.
  • Safety and Retention Details:

    Integrated locking mechanisms and extraction limit stops can be reviewed where accidental release or over-travel must be controlled.

Fan Pullers for Safe Removal of Press-Fit Cooling Fans

Perseus fan pullers are purpose-built tools for safe, damage-free removal of press-fit and tight-tolerance cooling fans from heat sinks, cold plates, and chassis mounting bores in military and aerospace electronics. These tools distribute extraction force evenly around the fan frame to prevent bending, cracking, or damage to fan components, mounting surfaces, or adjacent electronics during maintenance.

Puller designs are available for common fan frame sizes from 40mm through 120mm, with jaw configurations that engage the fan frame mounting flange without contacting the fan blades, motor housing, or electrical connector. Tool materials and heat treatment are selected for durability in depot and field maintenance environments, with operating temperature ratings appropriate for standard maintenance conditions.

Engineering answer: Always use the specified puller size matched to the fan frame diameter. Using an incorrectly sized puller or improvised tools can concentrate force on a small section of the frame, leading to fan damage, heat sink fin deformation, or damage to the mounting bore that compromises future installation fit.

Engineering answer: Apply extraction force evenly and progressively using the puller's center screw mechanism. If the fan does not move with reasonable force, stop and verify that all locking devices, retention hardware, and electrical connectors have been fully disengaged before continuing.
