- Indicates pressure level at which continuous operation is possible.
- Indicates max. air flow rate. (Static pressure: 0 kPa.)
- Actual operating noise measured on a new pump with the ORION recommended motor running under vacuum/pressure conditions. Operating noise level is from a position of 1 m in front of the unit and at a height of 1 m.
- Please choose one of the inlet/outlet flange options from G1 to G5 when making your order.
- Permissible ambient temperature range: 0 to 40 ℃, under normal humidity (65 ±20%).
- Specifications tolerance range: ±10%.
- Permissible power supply voltage fluctuation: rated voltage ±5%.
- Please install an overload protection device (such as a thermal relay). Use the current rating listed on the motor nameplate as a guide when setting the protection device.
- Always operate with a relief valve to ensure that the discharge pressure and degree of vacuum noted in the specifications chart are not exceeded. Failure to do so can lead to motor overload, burnout, and/or locking-up of the blower.
- Always operate with an air filter to ensure that foreign matter is removed. Failure to do so can lead to trouble from the accumulation of particulate within the close tolerance sections of the product.
- For detailed specifications, be sure to confirm the information on the product specifications document.

- In order to remove foreign matter, always install and operate an intake filter (one of the available accessories) with the Side Channel Blower. Failure to operate with an intake filter can lead to trouble from particulate clogging within the close tolerance internal parts of the product.
- The above-mentioned intake filter, air muffler and other products are general-purpose items that can work with other devices and will require a bushing or other part to adapt to the required connection diameter. Please contact us for details.
Regarding Piping Installation
A flange set and relief valve are required when installing 2BH models.
Please see our catalog of Dry Vacuum Pumps and Blowers for details.
