FAEBI ® 20 Rubber air-spring for highly, effective insulation of machinery and sub- assemblies against impact and oscillation. The bell-shaped component is made of high-grade elastomer. The construction allows a highly effective insulation without the disadvantage of excessive horizontal deflection. It is impossible for the element to break down as a result of overloading or a sudden drop in pressure. To reduce vertical dampening, the component is available with additional attenuation. The baseplate is equipped with an anti-slip plate so there is no need to anchor the machine to the floor. Note: For outdoor use (e.g. isolation of a roof top air condition unit) the FAEBI ® can be supplied in stainless steel and EPDM elastomer version. BILZ Level Controller Systems Level control is important part of an optimally functioning air-spring system. Level control can be utilized whenever load changes occur on rubber air-spring insulated machines, causing an unwanted one-sided spring deflection of the air elements, e.g. tilting of the machine. Insulation against Impact and Oscillation Depending upon the static load, the natural frequency of the elements varies between to 2,5 – 6 Hz in vertical direction. The ratio between vertical and horizontal natural frequency is 1– 1,2. Maximum spring deflection during impulse load is approximately 15 mm. Range of Application Excellently suited for active insulation of high-speed power presses, forging hammers as well as other machines and equipment with high dynamic forces. Passive insulation of measuring and testing machines as well as high-precision machine tools. Can be supplied optionally with electronic or mechanical level control! (See page 21) Assembly The components are screwed on to the machine by means of pre- drilled holes. It is not necessary to anchor the machine to the floor. The machine is placed on deflated elements which are then inflated to a maximum of 5–6 bar via a standard valve. To level the machine, air can either be released or added. The maximum height adjustment available is 10 mm. Control of Air Pressure Upon request, FAEBI ® elements can be equipped with an air pressure monitor.This monitor will indicate if air-pressure goes below the desired value.
