Vacuum Pump Enclosures Promote Silence of the Labs
Laboratories with mass spectrometers and scanning electron microscopes are often annoyingly noisy. The culprit? The ubiquitous vacuum pump, that steadily whines at an irritating 500Hz.
One or more rotary pumps or scroll pumps are typically required to maintain primary vacuum for the turbo molecular pumps that provide the high vacuum required for operation. The mechanical parts rotating in the pump motor generate a distracting racket. This noise makes working conditions around mass specs and SEM's uncomfortable and tiring for anyone who works in the lab.
Contrary to the claims of vacuum pump manufacturers, technologies are not yet available to produce a truly silent vacuum pump. The MS Noise solution? A Noise Reduction Box, a specially designed soundproof vacuum pump enclosure made of plastic and special materials to improve noise absorption.

Introducing MS Noise Vacuum Pump Enclosures
Noise reduction boxes, manufactured by MS Noise, reduce vacuum pump noise by three quarters, or 15 dB(A). They consist of two main parts: a base and a cover. Installation is very easy and is achieved without tools or disconnecting the vacuum pump.
There is convenient access for system checks and maintenance. Some models have a side window to check oil levels, and a side trap door for access to the screw ballast.
Pipe and cable connections are enclosed by polypropylene brush material, which provides protection against dust and contributes to additional soundproofing. This design concept simplifies installation and allows much better compatibility to the wide number of available vacuum pumps.
We accommodate virtually all models of vacuum pumps.
Thick polyurethane acoustic foam material covers the interior part of the box. The foam has open cell construction that delivers very good noise absorption. The wavy form factor of the foam multiplies absorption capacity by increasing the surface area for sound reception. The foam is fire resistant and complies with FMVSS 302 and DIN 4102 B3.
The noise reduction level obtained by the combination of foam and plastic structure, with the pipes and cable inputs/outputs closed by a brush polypropylene is about 15 dB(A). Decibels are a logarithmic scale, so consider that the MS Noise vacuum pump enclosures reduce your vacuum pump noise by 75%.
Our boxes are built for installation on the floor, thus precious bench space is not wasted. And they can also accommodate mist filters.
Think about it; you get some peace and quiet, and your pump emissions do not have to circulate in the lab.
All requirements related to lab safety are taken into account in the construction (ventilated box by bearing fans, use of non flammable materials, and use of heat resistant materials). MS noise reduction boxes conform to the European directive related to low voltage equipment 73/23/CEE.
An optional oil pan for vacuum pump storage is available. It is made of steel, and powder painted resistant to oil. This oil pan is equipped with four vibration absorbing castor wheels, in order to be able to move the pump and box easily. Two of the four wheels are equipped with a brake blocking system.
Enclosed vacuum pumps concentrate heat. The box ventilation system consists of two fans with a total air flow of about 250 m3/h, or over 1000 air exchanges per hour inside the box. The fans have long lasting ball bearing mounts, which guarantees quiet operation and much longer lifetime.
