INSTALLATION & OPERATING INSTRUCTIONS
ALLOWABLE NOZZLE LOADS
Allowable nozzle loads on a silencer will depend on the method of support, type of silencer, material of constructions, and operating temperature. Specific load limits can be provided on request. Typically standard silencers have limited nozzle load capabilities. Users should specify wind, earthquake, differential thermal expansion, and super-imposed loads.
Flow arrows will indicate the required direction of flow. Many designs are bi-directional and may not have a flow arrow.
Silencers exposed to liquids should be equipped with low point drains. Liquid service should be specified by the user.
SILENCERS INSTALLED COMMON TO MORE THAN ONE FLOW SOURCE
It is not recommended that a silencer be installed in a system with more than one flow source without special operation and design considerations. Consult the factory for specific guidelines.
ACOUSTIC RESONANCES & PIPE LENGTHS
Acoustic resonance’s can develop in the piping between the silencer and the noise / flow source. The silencer should be installed as close as possible to the source.
VANEC silencers are all welded construction; spare parts are not required or available.
