Tico LF Low Frequency Mounting Pad
Where attenuation of vibration is the prime factor, Tico LF / PA pads provide the well-proven scientific answer. These pads isolate disturbing frequencies where expensive rubber-in-shear or spring devices may have been considered. They are flat and naturally stable under compressive stress, therefore side restraints are rarely needed to ensure a sturdy installation.
Tico LF / PA pads have a bonded-sandwich construction. The centre layer is synthetic elastomer, precision moulded with a fluted pattern developed for optimum vibration absorption across a specific load range. Top and bottom layers are bonded cork to provide high-friction bearing surfaces. Double layers of Tico LF / PA pads can be used to achieve a lower natural frequency.
Typical Applications
Heating and ventilation systems with air conditioning units, boiler plant or fans sited near or above inhabited or other critical areas.
Heavy compressors, critical areas.
Business/computer systems.
Precision production plant, test and inspection equipment, sensitive instruments, etc.
Key Features:
Excellent isolation at low frequencies.
High lateral stability.
Isolate structures from plant vibration.
Isolate equipment from structural disturbance.
Two grades to suit most applications.
Rapid installation.
No mechanical parts to maintain.
Should be used in conjunction with Tico adhesives, provides major savings and prevents floor damage.

Calculating Static Deflection
1/ Calculate the stress on the pads using the formula:-
Stress in kN/m² = (Weight of machine in kg x9.81) / 1,000
Area of pad in m²
2/ Project the horizontal line from calculated stress to intercept desired thickness. Read the deflection off the horizontal axis of the graph.
Calculate Natural Frequency
1/ Calculate the stress of the pad from information above.
2/ Read from vertical axis across to desired pad thickness.
3/ Read Natural Frequency (fn) off horizontal axis.
