PSI Atmospheric Degassers


  • Mud (drilling fluid) is pumped from the bottom of the pit by the unit’s powerful 10 HP TEXP motor and directed to an elevated separation tank.
  • Within the tank, a baffle plate creates a sheet of high-pressure drilling fluid against the tank wall, facilitating the escape of entrained gases through a vent pipe for disposal.
  • Degassed fluid then flows downstream through a discharge, ensuring efficient processing.

Model Options

  • Two models are available:
    • ATMDG-S Standard Model: Designed for mud pits up to eight feet (8′) deep.
    • ATMDG-DT Deep Tank Model: Specifically engineered for pits deeper than eight feet, providing versatility to accommodate various pit depths.

Safety and Durability

Constructed from rugged high-quality American steel, with exterior surfaces coated with industrial-grade polyurethane and internal surfaces epoxy coated, guaranteeing long-wearing durability even in demanding environments.

Atmospheric Degassers

Compact Design

Both models are compact, allowing for easy integration into virtually any application while still leaving ample room in the pit for additional mud handling equipment.


The unit is capable of processing fluid to within 16 PPG at flow rates of up to 600 GPM, making it suitable for a wide range of drilling applications.


The PSI Atmospheric Degasser is specifically designed for removing entrained gases from drilling fluid, providing a compact and cost-effective solution for this critical process in drilling operations.


Featuring an insulated, explosion-proof starter/motor combination, the units ensure safe and trouble-free operation.
