Suction filter G 2½
From
€136.10*
Suction filter (with metall cover) G 2½" for side channel blowers
suitable for: Side channel blowers in pressure mode
Function: The side channel blowers operate with very small clearance for the compression, therefore the use of a filter is obligatory.
technical data:
air flow:
480 m³/h
fits for:
SKV-NS-530SKV-ND-520
Attention: Safe attachment of the suction filter to the SKV only possible with 90° bend!
Silencer G 2½" (metal)
From
€71.59*
Additional silencer for side channel blowers with G 2½" connection thread
suitable for: Side channel blowers in pressure as well as vacuum operation
Function: The side channel blowers are equipped with silencers at the pressure side as well as at the suction side. Corresponding sound pressure levels of the respective models can be found in the corresponding data sheets. Depending on the configuration further measures for sound insulation may be necessary. Our additional silencers can be simply connected in series with the silencers equipped by default. The assembly is possible via the factory-side threaded flanges. Using the additional silencers the sound pressure levels can be reduced by ~ 3dB(A) with the short version and by ~ 5dB(A) with the long version.
technical data:
Model:
Thread G 2½" (both ends)
Dimension (Diameter C / Length A):
100 mm / 270 mm or 570 mm

Inline filter G 3"
From
€391.29*
In-Line-Filter for side channel blowers and rotary vane pumps with G 3" connection thread
suitable for: Side channel blowers and rotary vane vacuum pumps in vacuum operation
Function: The use of a filter for protecting the side channel blowers as well as the rotary vane vacuum pumps is obligatory. The pumps operate with very small clearance for the compression, so penetrating dirt would damage the device. In the case of the rotary vane vacuum pumps, it would additionally decrease the service-life of the equipment.

Safety valve RV30 (3")
From
€101.97*
Safety relief valve RV30 for side channel blowers with G 2½" and 4" connection thread
suitable for: Side channel blowers in pressure resp. vacuum operation
Function: The side channel blowers are cooled by the external motor fan as well as by the air to be delivered in the side channel. Therefore a safe and proper operation is only possible if the side channel blower is operated below the maximum permissible pressure difference. The use of a safety valve ensures that an adequate amount of air is always available for the cooling of the unit. The safety valves are adjustable and should be set to 90% of the maximum differential pressure of the corresponding side channel blower model.
technical data:
Description:
Safety relief valve manually adjustable(not pre-adjusted!)
Application:
for limiting a maximum pressure resp. vacuum
Spring:
V2
Material:
aluminium
Options:
- without filter: pressure operation (limited also in vacuum operation)- with filter: vacuum operation
fits for:
SKV-NS-530 up to SKV-NS-1370SKV-ND-520 and SKV-ND-1110SKV-NDF-900 up to SKV-NDF-2050
Attention:
Don't forget to order the T-neck!
The adjustable range depends on the used blower model and the operation mode!

400 V power supply cable
From
€30.90*
400 V power supply cable for side channel blower
Description:
400 V power supply cable with 3 m or 5 m length
Note:
According to standard EN 60204-1 an electric motor with a rated power of more than 0.5 kW has to be protected against overheating. The use of a motor protection switch protects the motor against overload as well as a short circuit.A direct connection without motor protection switch is only possible in accordance with this standard.
Motor protection switch 10 - 16 A (400V)
From
€31.42*
suitable for: Side channel blowers and rotary vane vacuum pumps
Function: According to standard DIN EN 60204-1, motors with a rating of more than 0.5 kW must be protected against unacceptable heating. This applies to the majority of our side channel blowers. A motor protection switch ensures both overload protection and short circuit protection for the cables and lines. If an unacceptable current increase, e.g. by overloading or blocking the motor, the motor protection switch interrupts all active conductors. An overload protector as well as phase loss protection can not be provided by a motor protection switch. For this purpose, further actions must be taken.
