The ASFF Series are adjustable spring floor isolators that provide a solution for low frequency vibration and impact attenuation by isolating disturbing frequencies. The ASSF Series use the spring elements within a cast housing that are positioned within the floating slab while still accessible from above for adjusting the slab to a specified height.
Spring supported concrete bases have long been used to isolate individual pieces of equipment. The ASFF adjustable spring jacks have expanded on that concept – from the support of an individual piece of equipment, to supporting an entire room. The design consists of two reinforced concrete slabs – the floating or isolated wearing slab and the structural floor slab.
The floating floor slab is designed with a minimum thickness of 4″ between the structural and the floating slabs. The ASFF Series serve as a permanent load bearing resilient material that connects the two slabs while isolating the floating floor form the base floor. ASFF mountings offer permanent, safe support for both the floating slab and the imposed live load over the life of the building.
