Frequently asked questions

What is the noise level of the unit?

For all sizes of unts, we produce our own acoustic covers, adapted to the location and customer requirements. These in conjunction with our silencers show a high noise attenuation efficiency.
At the same time, we design the set in the middle band of the speed spectrum so that the resulting sound pressure level is as low as possible.

How fast will you process my inquiry?

If we know all the parameters, then processing and sending the offer is a matter of a few hours.
