![]() ![]() ![]() Ideally isolator deflection should be more than three times greater than the deflection or “sag” of the support. The key is to select isolators that are “softer” than the supporting building structure. Is equipment LOCATED on a RIGID concrete building structure or a FLEXIBLE VIBRATION SENSITIVE structure? If RIGID, use tall “double deflection” neoprene or springs If FLEXIBLE, use springs only. ![]() Vibration from equipment running at slow or variable speeds can pass through low deflection isolators and possibly be amplified by them. Is slowest equipment SPEED ABOVE 1200 rpm? If NO, use spring mountings.To Select The Proper Isolation For Mechanical Equipment in Most Applications You Need to Ask: (The importance of location is the same for isolating suspended equipment.) SELECTION If equipment is running below 1200 rpm, springs are required regardless of location. The key to proper isolator selection in upper levels is to make sure isolator deflection is much greater than floor deflection. On upper building levels where the structure can be very susceptible to vibration, springs are necessary. Neoprene mountings are satisfactory under equipment on a very stiff support structure such as a ground supported concrete slab. The location of your equipment in the building is the main deciding factor in selecting either neoprene mounts or springs. Sensitive Structural Supports Require Greater Deflections ![]()
