Vibration Isolation Mounts are designed to isolate noise, reduce resonant vibration and lower structure-borne noise.

They can be used for a variety of applications including isolating everything fans, motors, pumps, machinery, and compressors to air handling equipment.

Both Isolation Mounts (spring and neoprene) work well for vibration control and high frequency sound reduction, but if you need low frequency airborne sound reduction as well, we recommend using the spring mounts.

Spring mounts are designed to isolate machinery. The mounts come with a double deflection neoprene friction pad on the bottom to prevent slippage and lower sound transmission. The top has a spring loading and adjustment bolt with a locking cap screw. The adjustment bolts are very substantial because they must be made rigid enough to maintain the alignment at the top of the spring with the base plate. The head of the bolt is actually the equipment supporting surface.

    I believe I traced the source of a persistent low freq (16-60 Hz) humming noise throught our home, to our Air Condx Air Handler unit which rests horizontally and directly on our attic floor joists. In fact, the noise is audible even when the handler unit is switched off. Will the attached rubber isolator mounts be effective if I place them between the bottom of the air handler cabinet and the wooden floor joists? If not, is there any other remedy? Thanks, Leo

      Hi Leo,

      These isolation mounts would definitely work for your application. You can also check out our isolation pads which would also be effective. Please feel free to call in with any additional questions! 800-782-5742

    I am looking for some type of isolator for mounting a diaphragm pump that weighs approximatly 65lbs. The pump has four rigid 1/2in dia slots on frame for mounting to isolators. The area in which the pump is to be mounted is both unlevel and the product that is pumped is a brine solution. Therefore we require something that is corrosion resistant if not corrosion proof. All metals must be stainless, we will fix mounts to the floor (tile over concrete).

      Hi Marcus,

      All of our isolation mounts with cap and screw are made with steel and may begin to corrode over time if immersed in brine. Please call in and speak to one of our technical sales reps so they can try to find a viable solution for you: 800-782-5742

    We live in a condo which was quiet until our upstairs neighbor returned from a long medical absence with a large oxygen concentrator unit on casters which she needs to run continuously. It is set up close to a wall, on her floor which is our ceiling, also close to a cross beam. It produces noise, and also a great deal of vibration in our ceiling, walls, and the cross beam. We tried supplying foam rubber to place underneath it, but that only dampened the vibration a little. This is driving me crazy. What will best eliminate both the noise and the vibrations in our walls and ceiling?

      Hi Andrea,

      You will probably need to treat the vibration and airborne sound from the tank separately. You had the right idea putting the machine on something to absorb the vibration, but foam rubber may be insufficient for the amount of vibration. I would suggest using one of our isolation pads instead. Stopping the airborne noise from the tank may be a little more complicated. Mass is what stops airborne noise, and mass loaded vinyl is great at this, but this goes inside a wall or ceiling during construction, which for you it’s a little late. What you can do is dampen the sound by using a damping compound on a new layer of drywall and applying it to your existing ceiling and wall. If you want to go a step further you can isolate your new layers of drywall with resilient isolation clips, creating a ‘dead space’ between your existing wall and ceiling and two layers of new drywall with damping compound in between. This is often referred to as ‘room within a room’ treatment or a ‘floating ceiling’ or wall. When adding new drywall, make sure to seal up all cracks with acoustical caulk. A 1% opening lets in 50% of the sound. These applications can be tricky, so please call in and speak with one of our knowledgeable sales reps if you have any questions: 800-782-5742

    I have a front loading washer/dryer(siemans) that is supposed to be on a concrete slab. It is instead on the first floor. What isolation mounts would you suggest?

    Our non-profit shelter recently aquired some recording studio equipment that we want to use to make money for the shelter. The studio space is 2nd floor above a garage. Drums make the floor act like a resonator. We would like to make an 8×8 ft riser to place drumsets on so that they don’t transfer the vibration to the floor. What would we use, how many, placed where?

    • :

      I would consider first, adding a layer of 1/4″, 1# IsoStep completely covering the floor and adding a layer of carpet pad and carpet over top. If building a riser, you have to remember that that too, will act like a resonator (2×6 framing members, plywood flooring, etc, creates a hollow “box”). If you build a riser, you should use Green Glue Dampening Compound between two layers of flooring and put cotton batting insulation in-between the framing members underneath and seal it on the bottom with a thin layer of ply. It’s going to be a heavy riser so you may want to make 2 smaller ones that you can move about easily. IsoStep will still be the more critical product needed and, yes, treating the whole floor would be almost necessary since the untreated floor will be a weakness and still radiate to the space below. Adding some acoustical panels to the space behind the drums and on the walls right and left of the drums would also be recommended in order to reduce the overall reverberation throughout the space that can leak into the walls and transmit to the areas below that 2nd floor.

    Hello, We live in a condo. Each unit has an HVAC system. They cause our floor to vibrate which then comes up through our bed. Do you have something I could put under each of the four legs to damp out the vibration? Milt Waxman 11939 Gorham Ave. Unit 306 Los Angeles, CA 90049-5365

      The quickest and easiest solution to you problem is to put an AlphaIsolation cup mount under each bedpost. Go to the AlphaIsolation Cup Mount product page for more information.

      The solution that would work better, but cost more, is to install IsoStep Floor Underlayment beneath the carpet, laminate or wood in the entire room. See the IsoStep Floor Underlayment data sheet for more information.
