The characteristics are valid for the inlet of air with a relative humidity of 50 % and a temperature of 20 °C at a atmospheric pressure of 1013 mbar abs. and water at 15 °C as operating liquid.The tolerance is ± 10 %.
The motors are supplied as standard for the input voltage ranges of 50 and 60 Hz and for the protection category IP55 as well as approbated for UL and CSA. Compressors with ATEX 94/9 EG for category 2G are available, too.

The motors are designed according to DIN EN 60 034 / DIN IEC 34-1 andtemperature class F. For the three phase machines the tolerances are ± 10 % for fixed voltage and ± 5 % for voltage range.For all three phase machines according to UL and CSA norm (UL 507 and CSA 22.2 No. 100) the maximum allowed voltage tolerances are -10 % resp. +6 %. The frequency tolerance is maximum ± 2 %.
All L-BV2 achieve the standards and norms of the low voltage directive 72/23/EWG,L-BV2 achieve the standards and norms of the low voltage directive 72/23/EWG,BV2 achieve the standards and norms of the low voltage directive 72/23/EWG,rotating electrotechnical motor EN 60034-1-34, electromagnetic compatibility (EMC)DIN EN 61000-0/-6/-4.

Vacuum pumps of the L-BV2 range are suitable for evacuating gases and wet vapours down to inlet pressures of 33 mbar abs.(97% vacuum). All these vacuum pumps are equipped with built-in cavitation protection. For operation below 80 mbar abs. the cavita-tion protection should be connected to protect the vacuum pump.All pumps L-BV2 are especially space-saving in their monoblock design. They are available in cast iron (standard color RAL 9006). The motor is painted as standard in RAL 9006.

The motors are designed according to DIN EN 60 034 / DIN IEC 34-1 andtemperature class F. For the three phase machines the tolerances are ± 10 % for fixed voltage and ± 5 % for voltage range.For all three phase machines according to UL and CSA norm (UL 507 and CSA 22.2 No. 100) the maximum allowed voltage tolerances are -10 % resp. +6 %. The frequency tolerance is maximum ± 2 %.
All L-�V2 achieve the standards and norms of the low voltage directive 72/23/EWG,L-�V2 achieve the standards and norms of the low voltage directive 72/23/EWG,�V2 achieve the standards and norms of the low voltage directive 72/23/EWG,rotating electrotechnical motor EN 60034-1-34, electromagnetic compatibility (EMC)DIN EN 61000-0/-6/-4.
