Design Questions to Consider

When designing an effective vibration isolation system, it is crucial to address several key factors to ensure optimal performance and reliability. By carefully considering the following design questions, you can tailor your isolation solution to meet the specific demands and constraints of your project.

Sources of Vibration: Identify where the vibrations are coming from.

Frequency Range: Determine the frequency and amplitude of the vibrations.

Regulatory Standards: Ensure compliance industry standards and regulations as well as with local building codes in regards to seismic and wind control.

Weight and Load Distribution: Consider the weight and how it’s distributed.

Environmental Conditions: Assess temperature, humidity, and exposure to harsh conditions.

Space and Installation Constraints: Evaluate available space and installation challenges.

Impact on Adjacent Structures: Consider effects on nearby structures and equipment.

Product Offerings

Modern building techniques, which utilize longer spans and thinner floors, have made today’s structures more vulnerable to noise, vibration, and related issues from HVAC equipment, as well as seismic and wind events. At Hahn Mason, we provide a comprehensive range of products and services designed to protect buildings, equipment, and occupied spaces from the unwanted intrusion of vibration, noise, and seismic energy.

Spring Mounts

Hahn Mason provides a comprehensive selection of spring isolators engineered to minimize the transmission of vibration, impact, and noise across various commercial construction applications. From small fans to heavy-duty HVAC equipment, our spring-based isolators effectively diminish these factors while enhancing product stability and extending equipment life. Our spring floor isolators come in four configurations for floor-mounted equipment: open spring, captive, housed, and snubbed.
