Silent Line piston compressors
Do you need a quiet compressor that will disturb you or your colleagues as little as possible at work? ABAC brings a revolutionary soundproofing solution to its reciprocating compressors, thanks to a special plastic housing, with no major differences in overall dimensions. To make matters worse, it adds patented airflow technology for better heat dissipation. ABAC Silent reciprocating compressors are the best solution when it comes to peace and quiet in the workplace. Just take a look for yourself - up to 61 dB instead of the usual 93-97 dB...that's a big difference for your ears! Want to learn more about silent compressors? Then click continue.

ABAC Silent reciprocating compressors are designed with an emphasis on long service life (as evidenced by the robust cast iron cylinders), but also on ease of operation, the possibility of service intervention, the time of which is monitored by a motor hour counter, but above all on the lowest possible noise pollution of the surroundings. It saves your ears thanks to special, patented aggregate covers with acoustic foam on the inside. Add the simple opening of this cover, the easy oil quantity check from the outside and the branded pressure switches that ensure 100% trouble-free automatic operation of the machine, and you have the ideal slow-speed compressor for both corporate and small business.
What about compressor noise levels?
|
|
The overall noise level of a compressor is affected by a number of operating factors, such as airflow through the intake filter, the cyclical movement of the piston and connecting rod, the sound emitted by the valves on the valve plate, or the whistling of V-belts. | |
|
The noise level value is characterised by two basic quantities, both using the decibel dB(A) as the unit. The acoustic power level Lwa expresses The acoustic pressure level Lwp expresses |
For clarity, our catalogue gives both values, the acoustic power level Lwa and the acoustic pressure level Lwp at a distance of 4 m from the noise source and when the sound wave propagates on a hemispherical surface. There is an exact mathematical relationship between Lwa and Lwp (4 m) and the above-defined acoustic pressure level Lwp (4 m) is almost exactly 20 dB(A) lower than the acoustic power level. Knowing the differences between Lwa and Lwp is essential for a correct understanding of the data when selecting a silenced compressor. |
