Automatic Dehydrator, 230 VAC

Rev : A | Rev date : 23 May 2024

The GIBSON X F4 Automatic Pressurization Dehydrator is designed to protect air dielectric cable systems up to 950 l. 
The dehydrator includes a self contained completely automated air drying system that utilizes a pressure swing moisture absorption cycle to provide pressurized dry air. This eliminates the need for replacement or manual reactivation of the desiccant and together with the flowmeter leakage monitoring makes the GIBSON X F4 dehydrator ideal for unattended operation.
The diaphragm pumps hold a pressure of 12 kPa. 


  • Flow rate 250 Nl/h +/- 10%
  • dew point better than -40°C @ 30°C Ambient temperature and 85° relativ humidity
  • two pumps each with one drying chambers running alternatively
  • drying chamber automatic regeneration
  • microprocessor controls low pressure and power failure alarm
  • local alarm signalling
  • mounting: wall, floor, 19" rack
  • including flowmeter for leakage easy detection
