Shop Mufflers for Central Vacuum Systems
How do I select the best muffler for my central vacuum system?
All central vacuums use a motor to create suction, some motors are noisier than others. Noise also carries vibration generating around the unit as well as vibration in the walls. Professional installers and technicians will always recomend the central vacuum Activac II HEPA exhaust muffler/filter when completing a new or existing central vacuum installation. Purifies your air and deodorizes it all at the same time.
Are you trying to lower the noise level coming from the central vacuum? Is there a rattling noise in the house when the vacuum is running? Which is frustrating when you are using the system. First and foremost think of what an automobile muffler does for a car, reduces sound and vibration, a central vacuum muffler does the same for the vacuum. Lessens the noise levels making it easier on the ears. Mufflers are universal for all central vacuums.

How do Central Vacuum Mufflers work?
All vacuum manufacturers seek to lower the noise level their vacuum cleaners produce as much as possible and some have done a great job so far. In reality, the whole burden of reducing the noise level is carried by these small accessories called mufflers. The technology used and the operation mode of these accessories are impressive yet quite easy to understand, so here is a little insight into how central vacuum mufflers work.
Sound is produced by the fluctuations in the air pressure. With engines, these fluctuations are caused by the opening and closing of exhaust valves and the entrance of high-pressure gas in the system. Here, it meets the low-pressure one in the pipes and the two collide. However, their collision, or rather overlapping, happens a little further down from the entry spot, which leads to the formation of a low pressure area. This whole process allows the noise to advance much faster than the gases. As far as the perception of noise is concerned, it is determined by two main factors: the sound wave frequency and the air pressure level. Normally, the noise production increases in direct ratio to the number of sound waves. However, this is not always the case.
All the sound waves that reach the ear at a given moment sum up and produce a certain noise level. The interesting fact is that there can be two opposite sound waves, in which case they cancel each other out. This is the principle used with some headphones. Two sound waves can be in phase, in which case they produce twice as much noise but the frequency remains unaltered. This principle is known as constructive interference. Otherwise, their sum is zero. This principle is known as destructive interference. In this case, the maximum pressure level is reached by the first sound wave at the same time the minimum pressure level is reached by the second.
Central vacuum mufflers conceal a number of holed tubes that block the sound waves the vacuum cleaner produces, thus cancelling out the noise. The sound waves and the gases reach inside through the central area of a muffler, after which they hit the muffler wall and are reflected into the main body. The holes in the tubes allow them to move from one chamber to another. Once they reach the last one, they turn and exit the muffler. The resonator chamber is the second chamber inside a muffler. Its length and capacity are calculated to cancel the frequency of the sound wave that enters it. However, these frequencies may vary, so mufflers are designed to be able to cancel a range of frequency rather than a specific one.
There is no term of comparison between an appliance equipped with a muffler and one that does not have such an accessory. The reasons why central vacuum manufacturers seek performance on this level of noise reduction are obvious. Some people can only install their central vacuums around their living area or their neighbors’ living area, so they need their central vacuum cleaners to produce as little noise as possible. This is where the central vacuum mufflers come into play, so they play a crucial role in the manufacturing of comfortable and bearable cleaning equipment.
What kind of central vacuum muffler should I use?
Some mufflers come in different shapes,sizes,lengths and varied thickness. Typically they are constructed from PVC and sound suppressing acoustic foam which absorbs a good majority of noise levels and vibration. All are made to lower the decible levels of the central vacuum making it quieter, some do a better job than others. They typically dampen the sound level from 1 to 7 decibles, making it more enjoyable to own a central vacuum system.
What is the best central vacuum muffler?
A new style muffler dust reducer and purifier has revolutionized the central vacuum muffler industry. It is called the Activac II. It is the industries first and true certified H E P A exhaust muffler/filter for central vacuums. It can be used on 98% of all central vacuums made today. It contains and traps 100% microscopic allergy pollutants from escaping your vacuuum system. No other muffler in the United States can gaurantee that. The newest technonlogy and top of the line muffler on the central vacuum market is the all new activac II-hepa filter. This new advanced and acoustic designed muffler not only deadens the sound, it also purifies the exhaust air. There are three major reasons for buying the best the first time...1) Sound reduction 2) Purify the air 3) Deodorizing your unit. The Activac II muffler is great for allergy & asthma sufferers.
