An open Sonation sound insulation hood. Next to it a pump on an oil pan. In addition, various Sonation sound insulation hoods lined up.

Model SSH22

Model SSH22 is suitable for housing and insulating two vacuum pumps in a sound protection hood. The maximum pump size is approx. 230x270x600mm (WxHxD).
For mass spectrometers with two vacuum pumps, such as the Edwards E2M28 or the Agilent/Varian DS602, this is the optimal solution.


Active Pump Protection System (APPS)

The APPS (Active Pump Protection System) module (Active Pump Protection System) enables you to perfectly protect your sensitive and important devices by monitoring all important operating data.
The system constantly monitors all important operating data such as temperature, current consumption and the function of the fans. In the event of a fault, an optical and acoustic warning is issued. The ventilation is temperature controlled, so that the insulated device is optimally cooled at all times.


Sound protection
The noise level in the laboratory is significantly reduced which prevents hearing damage and leads to higher concentration and productivity.
Universal and flexible
By using pump-specific interchangeable covers, the sound protection hood fits perfectly to the pump used. If a different pump is to be insulated at a later date, this is easily possible by replacing the cover.
Simple commissioning
Commissioning of the sound protection hood can be carried out by the end user within a few minutes.
Easy pump access
Both the cover and the front can be removed with a flick of the wrist via quick-release fasteners. This makes it easy to check the oil level, operate the gas ballast valve or perform other work on the pump at any time.
Internal pump socket
All sound protection hoods are equipped with an internal socket for connecting the vacuum pump. This means that only one socket or cable is required to supply power to the pump and the sound protection hood. Separate power supply of the pump and the sound protection hood is also possible.
Temperature monitoring with alarm function - models with APPS (Active Pump Protection System)
The exhaust air temperature is continuously monitored. In the event of overheating, a visual and acoustic alarm is triggered.
Temperature-controlled fans - models with APPS (Active Pump Protection System)
The speed of the fans is controlled depending on the required cooling capacity, which contributes to an increased service life as well as optimal noise minimization.
Wide range input - models with  APPS (Active Pump Protection System)
The sound protection hood can be operated on 110V networks as well as on 230V networks.
Emergency shutdown function - models with APPS (Active Pump Protection System)
When a critical internal temperature is reached, it is possible to automatically switch off the internal socket to prevent a defect.
