NAV5 ANTI VIBRATION MOUNTING KIT 540823

Introduction

Nuaire NAV Anti-vibration mounting kits are available from i-sells.co.uk in both rubber (NAV1 to NAV6) and spring type (NAV37 to NAV58), the correct selection and type employed will depend on the accurate calculation of the weight of the assembly to be supported. For the full range and advice please contact the i-sells sales team.

General Installation

AV mounts should not be fitted to a fan/silencer assembly unless there are flexible connectors fitted between the assembly and associated ductwork. AV mounts should be installed with the matched mounting feet and positioned such that they carry an equal proportion of the assembly weight. This is particularly important where fans and silencers are installed on suspension rods

Please note: AV mounts isolate the fan only.

Silencers/ back-draught dampers and other  "significant mass" accessories should form part of the fixed ductwork after the flexible connection.

Rubber AV Installation

Secure the NAV to its mounting location using the two holes on the baseplate and appropriate fixings for the application (provided by others).

Lower the unit onto the NAV’s, ensuring that the mounting points of the unit are in line with the central inserts at the top of the NAV’s.

Screw the fixings i.e. bolts, washers and nuts (provided by others) through the mounting points of the unit into the central inserts of the NAV’s.

If the unit needs to be raised above the height of the NAV, additional nuts can be used for height adjustment (see fig. 3) or alternatively packing shims should be inserted either between the top cover and the unit mounting point or underneath the NAV as appropriate.

Once all NAV’s are levelled to their nominal working height, ensure the unit is level.

Maintenance

AV mounts are maintenance free but a periodical inspection is recommended to check the security of fixings and the condition of rubbers and springs.
