Combination Spring Hanger – Dual-Element Vibration Isolation for Enhanced Noise and Vibration Control

The Combination Spring Hanger is a high-performance vibration isolation solution that integrates a steel spring and a neoprene (or elastomeric) element in a single unit. Engineered for superior acoustic and vibration control across a broad frequency range, this hanger is ideal for suspending mechanical equipment such as HVAC ductwork, piping, fan coil units, and ceiling-mounted systems in commercial, industrial, and institutional applications.

By combining the low-frequency isolation capability of a spring with the high-frequency damping of a neoprene element, the Combination Spring Hanger delivers optimal performance in environments where quiet operation and structural protection are essential.

Key Features:

• Dual Isolation Elements: Incorporates both a steel spring for low-frequency isolation and a neoprene cup or washer to absorb high-frequency vibration and impact noise.

• Color-Coded Springs: Easy identification of load capacity and deflection values for quick selection and on-site verification.

• Robust Housing: Enclosed in a heavy-duty steel frame or box to protect internal components and simplify installation.

• Threaded Rod Mounting: Standard top and bottom threaded holes accommodate suspension rods for secure mounting from ceilings or beams.

• Wide Load Range: Available in multiple capacities and spring deflections to support light to heavy suspended systems.

Benefits:

• Wide Frequency Isolation: Controls both high-frequency noise and low-frequency structural vibration in one unit.

• Quiet Operation: Ideal for noise-sensitive spaces such as hospitals, studios, schools, libraries, and residential buildings.

• Extended Equipment Life: Reduces wear on mechanical systems by isolating vibration and shock at the source.

• Code-Compliant Design: Many models comply with seismic, acoustic, and mechanical code requirements.

• Consistent Performance: Delivers stable deflection under load, helping maintain system alignment and reduce maintenance needs.

Common Applications:

• Suspended HVAC ductwork and piping systems

• Fan coil units, air handling units (AHUs), and variable air volume (VAV) boxes

• Acoustically sensitive ceilings (e.g., in studios, theaters, lecture halls)

• Commercial and institutional mechanical rooms

• Data centers, laboratories, clean rooms, and healthcare facilities

Types of Combination Spring Hangers:

• Standard Combination Hangers: With basic neoprene and spring elements for general use.

• Pre-Compressed Combination Hangers: Factory pre-set to rated deflection for fast and easy installation.

• Seismic Combination Hangers: Include additional restraints for use in earthquake-prone regions.

• Custom Load and Deflection Options: Designed for unique system weights or acoustic requirements.

Why Choose Combination Spring Hangers?

Standard spring or neoprene hangers may not provide sufficient isolation across the full vibration spectrum. Combination Spring Hangers are the ideal solution when both structure-borne vibration and airborne sound must be controlled. Their dual-action design ensures smoother operation, better occupant comfort, and protection for both the building and mechanical systems.

Spring Hanger – High-Performance Vibration Isolation for Suspended Equipment

A Spring Hanger is a precision-engineered vibration isolation device designed to reduce the transmission of noise and vibrations from suspended mechanical systems into the building structure. Ideal for HVAC units, piping systems, ductwork, fans, and other suspended equipment, spring hangers use heavy-duty steel springs to absorb and dampen low-frequency vibrations, ensuring quiet and stable system operation.

Key Features:

• Steel Spring Element: High-tensile steel springs provide superior isolation from low-frequency vibrations often produced by heavy or high-speed mechanical equipment.

• Durable Housing: Constructed with a galvanized or powder-coated steel frame to resist corrosion and environmental wear in both indoor and outdoor settings.

• Load Capacity Options: Available in various spring ratings and deflection ranges to accommodate different equipment weights and dynamic load requirements.

• Color-Coded Springs: Simplifies identification during installation, ensuring correct selection for specific load ranges and applications.

• Flexible Installation: Designed for easy integration with threaded rods and brackets, suitable for installation in tight ceiling spaces and mechanical rooms.

Benefits:

• Superior Vibration Isolation: Effectively isolates and absorbs both vertical and horizontal vibrations, especially in low-frequency ranges, where other materials like rubber or neoprene may fall short.

• Noise Reduction: Reduces structure-borne and airborne sound transmission for quieter indoor environments in commercial, residential, and industrial buildings.

• Protects Equipment and Structures: Minimizes operational stress, extending the life of mechanical systems and preventing damage to surrounding structural components.

• Improves Comfort and Compliance: Meets acoustic and vibration standards for modern buildings, ensuring occupant comfort and regulatory compliance.

Common Applications:

• HVAC systems (fans, AHUs, chillers)

• Suspended piping and duct systems

• Ceiling-mounted electrical and mechanical equipment

• Generators, pumps, and compressors

• Acoustic isolation for theaters, studios, and performance spaces

Types of Spring Hangers:

• Standard Spring Hangers: For general-purpose vibration isolation in HVAC and mechanical systems.

• Precompressed Spring Hangers: Designed to maintain spring deflection during installation, simplifying setup and ensuring optimal performance.

• Combination Hangers (Spring + Neoprene): Offer enhanced vibration isolation across a broader frequency range, combining the benefits of both elastomeric and spring elements.

Why Choose Spring Hangers?

Spring Hangers are essential for vibration control in systems where dynamic forces and low-frequency vibrations are prevalent. Unlike simple rubber or neoprene hangers, spring hangers provide higher deflection and superior isolation, making them ideal for demanding commercial and industrial applications. With a variety of configurations and load ratings, they are a versatile and reliable choice for engineers, contractors, and facility managers looking to optimize system performance and occupant comfort.
