Inertia Bases

Inertia Base should be used where the machine to be vibration isolated produces large unbalanced forces which would result in excessive motion if supported directly on spring or rubber based isolators. They should also be used where the machine is subject to external forces or is inherently unstable.

AKINCO Inertia come in several standard sizes as listed in our catalogue. However, these can also manufactured to any size and specifications, even for heavier and more complex vibration isolation problems, where viscous damping may also be required. For frame lengths greater than 2400 mm we would normally recommend 6 isolators or more for exceptionally large bases. The base is to be filled with concrete having a mass of between 2300 and 2700Kg / M³

Longevity and Maintenance Benefits

When machines are mounted on properly designed inertia bases, the reduction in transmitted vibration is significant. This means less wear and tear on moving components, greater stability during operation, and fewer vibratory forces being transferred to structural supports or nearby equipment. Over time, this helps extend the operating life of the machinery and reduces the frequency and cost of maintenance interventions. By minimising disruptive movements, inertia bases also help to protect alignment, seals, and bearings, all of which are critical for the long-term reliability of pumps and similar mechanical equipment

Areas of applications

Typically used with vibration isolators for support and isolation of:

  • Chillers
  • Pumps
  • Compressors
  • Centrifugal Fans
  • Air Handling Units
  • Evaporative Condensers
  • Cooling Towers

Inertia bases find application across a range of environments where vibration control and noise reduction are critical. These include:

  • Commercial Buildings: To reduce noise transmission from HVAC systems and mechanical equipment, helping maintain a quiet and comfortable workspace.
  • Industrial Facilities: For protecting sensitive machinery and ensuring stable operations by mitigating the impact of vibration and external forces.
  • Healthcare Settings: In hospitals and clinics, minimizing noise and vibration helps maintain a tranquil environment essential for patient care.
  • Residential Complexes: Used to control noise from water pumps, air handling units, and other building services, enhancing the comfort of occupants.

Whether in a high-rise office tower, a manufacturing plant, a medical facility, or a residential development, inertia bases provide robust support and effective isolation to meet demanding operational requirements.
