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.
Seismic/Wind Rated Spring Mounts
Hahn Mason provides a wide array of captive spring isolators crafted to significantly reduce the transmission of vibration, impact, and noise across diverse commercial construction applications. Engineered to meet stringent wind and seismic requirements, these isolators provide exceptional stability and performance, even in the face of extreme conditions. The steel captive housing enhances the isolators’ structural integrity, offering superior protection against vibrations, impacts, and external forced. Our seismic spring floor isolators are available in three configurations for floor-mounted equipment: captive, housed, and snubbed.

Hangers
Hahn Mason offers a diverse range of isolation hangers available in neoprene, spring, and elastomer configurations. Our neoprene hangers are engineered to effectively isolate high-frequency vibrations in suspended piping and equipment, preventing vibration transmission to the building structure. Spring flex hangers are designed to isolate low-frequency vibrations, while elastomer and spring hangers offer isolation for both low and high-frequency vibrations. Each hanger is molded using color-coded elastomers, with springs color-coded for instant identification of loading capacities.
Seismic Bracing
Hahn Mason provides a comprehensive selection of seismic restraint products tailored for ceiling-suspended equipment and piping. Our seismic restraints are meticulously crafted to accommodate both isolated suspended equipment and non-isolated seismic equipment. For isolated systems, our seismic cable kits offer flexibility, ensuring proper installation with slightly slack cables to prevent short-circuiting of the isolation system. Available in various configurations and equipped with multiple mounting brackets, these kits facilitate a secure connection to the building structure. Crafted from aircraft cable, our cables are offered in different sizes and color-coded for easy identification, with factory-installed swaged ends for added convenience.
Neoprene Isolation Mounts and Pads
Hahn Mason provides a wide range of elastomeric isolators and pads designed to limit the transmission of structure-borne vibration. These versatile solutions are ideal for various applications, including HVAC and electrical equipment. Our elastomeric products are engineered to isolate and attenuate high-frequency disturbing energy, ensuring optimal performance and comfort.
