SPECIFICATION E

Mountings – SLR-MT Air Spring Mount SLR-MT restrained mountings contain MT air springs in place of the SLF springs in the SLR mountings. The steel housing around the MT air spring serves exactly the same purpose as the SLR housing in explanation D. SLR-MT are recommended in lieu of SLR in highly critical situations as…

SPECIFICATION D

Mountings – SLR Spring Mountings SLR and SLRSO restrained mountings limit upward travel when weight is temporarily removed and provide safety stops for windy rooftop applications. All mountings are shipped with removable steel spacers between the sides and the top plate of the mounting as shown in the illustration. When the spacer is in place,…

SPECIFICATION C

Mountings – Neoprene Mountings It is possible to reach frequencies as low as 84 cpm(1.4 hz) or even lower using steel springs and provide excellent isolation at RPM or the fundamental frequency, but noise transmission is another issue. The high pitched whines and hums developed by very high speed centrifugal, screw and sometimes reciprocating compressors,…

SPECIFICATION B

Mountings – SLF Spring Mountings SLF spring mountings are our standard for all high efficiency installations. This is a bare spring design with a good ratio between the diameter and the working height to assure lateral stability. Our suggested specification states “that the spring diameter shall be no less than 0.8 of the compressed height…

SPECIFICATION A

Mountings – Neoprene Mountings Double deflection neoprene mountings and double deflection rails are recommended for minor equipment or basement locations only. We have placed this limitation on all rubberlike materials because of their relatively minor deflections. SPECIFICATION A Neoprene mountings shall have a minimum static deflection of 0.35”(9mm). All metal surfaces shall be neoprene covered…
