AC – Fiberglass Mounts

AC Fiberglass Mounts are bolt-down fiberglass vibration isolators designed for audible frequency noise and vibration isolation of mechanical equipment. They are suitable for HVAC, MEP, rooftop, and equipment support applications across the UAE, GCC, and wider MENA region.

Product Description

Kinetics Model AC Fiberglass Mounts are engineered vibration isolators used where reliable isolation of audible frequency vibration or noise is required. They are suitable for mechanical equipment with lowest operating speeds of 1750 RPM when installed on a grade-supported slab or pier.

The AC Fiberglass Mount is typically selected where predictable dynamic response, permanent load support characteristics, bolt-down installation, and vertical lift control are required. Each isolator consists of a molded inorganic fiberglass isolation pad bonded to a steel load transfer plate and formed steel bolt-down bracket. An equipment anchor bolt with neoprene grommet helps prevent metal-to-metal contact, supporting effective vibration isolation.

The fiberglass media is stabilized during manufacture and coated with a flexible, moisture-impervious elastomeric membrane. This construction helps provide constant natural frequency over a wide operating load range, high energy dissipation, and controlled viscous damping. AC Fiberglass Mounts are suitable for utility ventilating fans, vane axial fans, high-speed motors, roof-mounted exhaust fans, and similar mechanical equipment used in commercial buildings, industrial facilities, mechanical rooms, rooftop plant areas, and infrastructure projects across the Middle East.

Specification

Vibration isolators shall be precompressed molded fiberglass pads individually coated with flexible, moisture-impervious elastomeric membrane. Vibration isolation pads shall be molded from glass fibers with fiber diameters not exceeding 0.00027″ (6.8 microns) and with a modulus of elasticity of 10.5 million PSI (750,00 kg per sq. cm).

Natural frequency of fiberglass vibration isolators shall be essentially constant for the operating load range of the supported equipment..

Vibration isolators shall be bonded to a steel load transfer plate and a formed steel bolt-down bracket and shall also include an equipment mounting bolt with a neoprene grommet to prevent metal-to-metal contact.

Vibration isolators shall be selected by the manufacturer for each specific application to comply with deflection requirements as shown on the Vibration Isolation Schedule or as indicated on the project documents..

Vibration isolators shall be Model AC, as manufactured by Kinetics Noise Control, Inc.
