Instruction Sheet
PHASE-A-MATIC™ Rotary Phase Converters have been developed, tested, and thoroughly proven over a 46 year period demonstrating exceptionally high reliability and long life. These converters are the workhorse of many commercial uses and multitudes of home shop machines. LIFE EXPECTANCY: The Rotary Converter has been in use for approximately 46 years and has already proven itself to be extremely reliable when properly applied. Phase-A-Matic™ was recently able to purchase back the first one that was ever sold, and it is still working fine. It is reasonable to expect the converter to be in good working condition and service for 20 or 30 years or more. We continue to hear back from customers who have them still running their equipment faithfully after 20 years and more.
Uses include: Lathes, Mills, Grinders, Drills, Saws, Metalworking and Woodworking Equipment, Printing Equipment, Sewing Machines, Garbage Disposals, Food Processing Equipment, Meat Grinders, Food Mixers and Blenders, Conveyer Belts, and numerous other uses.
Reliability, quality and construction of the PHASE-A-MATIC™
Rotary Phase Converter:
Baldor Electric/PHASE-A-MATIC™ Design . The rotary portion of our converter is proprietary, custom built to our specifications by Baldor Electric, one of the largest and most trusted motor manufacturers in the world, with warranty stations nationwide and worldwide. It is a true phase converter and not a modified electric motor as most of our competitors use. Many years of testing, changing and developing the converter in conjunction with Baldor’s engineers has produced a very simple and trouble-free converter with extremely low idle current and low noise level. Many of our customers confirm that our rotary converters are the quietest and most trouble-free available.
Simplicity of design; uses all soldered connections . Keeping the design exceptionally simple reduces the risk of electrical connection failure to almost zero since these are some of the most common causes of failure.We use only soldered connections with no mechanical electrical connections like spade clips, terminals or screws which can vibrate loose or corrode over time. There are no start capacitors, relays or contactors with connections which can come loose or arc and weld the contacts causing failure of the contactor and the start capacitors, and perhaps even the rotary converter or your equipment. Because of this we do not have circuit board failures caused by spikes generated by the magnetic contactors as some of our competitors do.
The Rotor . The PHASE-A-MATIC™ failure rate is practically zero because the rotors are specifically designed and manufactured for rotary converter use. However, some of our competitors emphasize that rotors often fail. This is because they machine standard electric motors, modifying and thereby weakening standard electric motor rotors, which were not originally designed to be used as a phase converter.
Testing before shipment . Every converter is performance tested before shipment and assigned a serial number. These records are kept for review if any questions should ever arise about the performance specifications.

Great for what it does but not a miracle
Style: 30 sqft
Sticks well. Definitely thicker and nicer than the Kilmat version. If I were buying again I would just buy more of this, the value is better even though you get less total coverage per pack.
Can be cut to size easily, we used a box cutter which got a little gummed but but not too bad. we were able to get it in and around everywhere we needed to put it and it held up well as we were mashing it into weird spots. It doesnt smell hardly at all while being applied and once its on there is no smell whatsoever The product is great for what it is. 4 stars only because I think it gets oversold for how much this alone can do. We did notice a slight reduction in noise but nowhere near the multiple decibels we see claimed everywhere. If your vehicle is mostly quiet but just has that little bit getting through this will probably do wonders, If you have a vehicle where there's significant engine noise in the cabin you'll need more than just this to bring that down.

Great product!
Style: 30 sqft
I can say this product makes a huge difference with road noise and is cleaner and easy to work with when applying compared to other mats that cost about the same price.

Very heavy and thick
Style: 30 sqft
I purchased mini brands of sound ending and this is by far the heaviest sound deadening I've ever ordered. I'm not installed yet but I have a good feeling that is going to work exceptionally in blocking sound. If weight is a concern for you I would recommend a lighter product however if sound quality and a quiet ride is your priority this is the one for you.

Siless Hybrid 3-in-1 - Far Exceeded my Expectations!!!
Model: SLH20025
I recently installed the Siless Hybrid 3-in-1 sound deadening mat in my vehicle, and I’m genuinely impressed. For just $80 for 25 square feet, this product delivers performance that rivals materials costing twice as much — and with far less hassle. If you're on the fence......Just buy it! You will not be disappointed.
Easy to Install: Unlike traditional sound deadening products that are stiff, sharp, and temperature-sensitive, this mat is soft, flexible, and easy to work with. I cut it cleanly with regular scissors and pressed it into tight spaces using just my fingers, so if in you don't have a roller or install tool, a good pair of scissors and your hands can get the job done. With other brands like Dynamat, the aluminum layer often leaves micro cuts on your hands and tears up your fingertips, but Siless does not due the acoustic layer being on top and above the aluminum layer that holds the butyl layer. So, it's very easy on your hands.
Even in cooler temperatures (around 50°F), I had no trouble applying it but it goes on better heated. If warm outside, I would leave the entire box out in the sun for at least 30 minutes when it's warm or heats it's very pliable and easy to mold. Make sure its where you want it because once applied it's not ever falling off. and it became even more pliable and easy to mold. No heat gun, no mess — just straightforward application.
I installed 40–50 square feet throughout the interior, covering everything except the headliner and the flooring forward of the rear seat. The difference in cabin noise is astonishing. I can turn my radio up concert loud with gut-punching bass, and from outside the car, it sounds like a factory sound system at mid volume. I was blown away by how well it contains sound — both inside out and outside in.
My exhaust is pretty aggressive and now is barely audible from inside the cabin. While driving, it almost sounds like a stock factory setup. The Siless matting actually changed the driving experience and feels refined.
If you're skeptical about sound deadening gimmicks, I get it, but this is the first product I've used and when I needed more, I went Stright to the 3 in 1 Hybrid matting and purchased it again. I love researching before buying and that's very uncommon for me to do.
Note: Proper installation is key, and it does take time and patience. But if installed correctly and in the right places, it works better previously used from paint-on sound deadening to Dynamat.
Update Nov, 2025
After using it this in 4 separate vehicles now. I feel the Siless’s 3 in 1 Hybrid has nailed it for best budget deadener that is better than dynamat extreme in performance and installation
Protip: buy a roll of 2-3” aluminum tape and tape the seams. After trimming the edges tend to very sticky between the panels. I ran a strip of aluminum tape over the seems to create a better seal and true moisture
I used it on four vehicles now and have I have not been paid to review and purchased every order myself.
3 in 1 Hybrid deadener by Siless is the best all around easy to apply sound deadner period!

Top quality
Model: SLH20025
This Siless Hybrid 3-in-1 sound deadening mat is easy to work with and feels high-quality. The butyl material is thick and pliable, making it simple to cut and fit into doors, floors, or panels.
After installation, road noise and vibrations are noticeably reduced, and it also seems to improve the overall cabin feel. No bad smell.
At 25 sq ft per roll, it’s a good value for anyone looking to dampen noise and improve car acoustics. Overall, a solid, effective option for automotive soundproofing. Used on a Fiesta ST.
